It all makes sense since the card isn't slower, just the connection is. So as long as you don't have much data to transfer it works at full performance, that's why this is useful for mining where you don't have to stream textures or rendered 4k ouput
I'm playing World of tanks on 1x using riser, no problem. GPU is R7 250 1 GB. Only, to solve overheating of GPU, I use Asus GPU Tweak II to adjust fan speed, voltage... Temperature is ~70° C and room temperature is ~ 18° C. Fan is on 75% and it's noisy...
thx for answering my question bub. here I still have my 1650 super from MSI. And I was about to hook my gpu to my mobo. But then I remembered, I still have a couple of these mining risers my ol' buddies gave me. But yo right. the small end is only 8 lanes. And todays graphics cards use all 16 lanes.
Vídeo not useless at all, this is exactly the information I needed. Interesting to see there's so little impact, initially I thought that being on 1 lane instead of 16 lanes would mean the VGA is 16 times slower... But no! Probably it is 16 times slower when it needs to transfer data from the processor/ram to the GPU, but after the data has been transferred and stored in the GDDR, then the VGA can chug happily through it without having the interface as a significant bottleneck. Also, as expected, some games are better optimized to load the necessary stuff to the VGA and keep most of the processing there, while other games that are not so optimized for that will rely more heavily on CPU/RAM and thus the PCIe becomes a bottleneck. This made me curious to see how would be the performance if the external VGA was connected to a laptop through its mini PCI express port... Or through the ExpressCard slot. Every laptop has at least one mPCIe slot where the wifi adapter is connected, would you please borrow a friend's laptop and test the external VGA on it?
Keep in mind, not all your PCIe slots are directly connected to the CPU, others are connected to the chipset on the motherboard. I think x1 PCIe slots tend to be connected to the chipset since they are often used for non-critical functions (like an extra USB card, or something) Also it doesn't matter if you use a x16 or a x1 PCIe slot, it will always run at x1 since that's what that riser card is wired for. And you're not really using USB 3.0, you're using PCIe protocol, it just happens that the USB 3.0 cable has enough wires to support x1 PCIe which can be a few meters long before signal loss.
The x1 slot going through the chipset was my guess as well. On z77 like you'd most likely be using with a 3570k the chipset lanes are 2.0 while the primary CPU lanes are 3.0. Some of his results were cut roughly in half and in situations where the PCIe bandwidth was the bottleneck that's pretty much what you'd expect since 3.0 is double 2.0's speed.
5:00 Because most data is being loaded into GPU RAM. On a 1x slot, Windows utilizes almost 20% of it's bandwidth, and the remaining is struggling to keep up the demand of textures and other video data. Once all that data is loaded, the GPU loads it from it's RAM(12-16GBps max), rather than load it via the much slower PCIE 1x connection (1GB/s max rate). Also, USB1x slot and USB through a full size 16x slot, is the same data rate, so performance should be the same. The only thing a full size 16x riser card slot offers over a 1x slot, is additional power to the GPU (1-4x slot = 25-35W, 16x slot is 75W; which might be the cause of lower performance on AMD cards, as the card now gets ~50W less power than on a USB 1x or 4x open end slot).
You can SLI/xfire with a riser card, but not an x1 riser card like this. SLI requires a minimum of an x8 connection on both cards while xfire requires x4.
It's not a a stupid test and it is not a stupid idea, apparently when you ran this test GPUs were not as expensive as they are now in 2020/2021 and I have had to go this route because low profile GPUs for my SFF build are ridiculously expensive now where they are available and so I got an affordable used GTX 750 TI of regular size and have had to change its orientation to fit my SFF case hence the necessity for this adapter arrangement. But thanks for letting me know what I'm going up against, just wondering it it will be better using the 16x regular extension riser.
You dont even realize it, This is a very interesting test for us computer science engineers thinking about pcie bandwidth and all the other technical stuff. Thanks for this piece of data.
he is very moderate and humble. This is not a stupid test. PCI e slot broken and then PCI e 1x is alive. then you can save that motherboard without much performance loss.
Very informative and I like your style of speech. It is transparent and thoroughly I can get it through clearly. Just plug and play then good to go and with simple explanation.
Nice that it works for you. I have a card that won't fit in the case I currently own so I tried this to no avail (device manager and driver installer don't recognize the card). My guess is the card needs more than X1 bandwidth.
Thanks for this. They are actually not supposed to use the USB branding for non compliant/licences devices, however I think this applies more for the USB insignia than the actual connector hardware. Using a USB 3.0 cable makes sense as they are cheap, shielded and have differential pairs. If you are planning to use this for a laptop via USB you are SOL
Dont call this a stupid video or a stupid test. This video helped me a lot! I bought an expensive GPU and it doesn't fit in my case. I need to make it into external and using this riser is my only hope.
hi can you give me some info? I have a riser plugged into an old core i5 laptop with no usb 3 connections, it does not seem to run the graphic card at all, the graphic card is powered by an external corsair vs650 power supply. I short the connections out for the power switch on the power supply and the graphic card fan comes on but it does not switch on the screen.
Q: There are two parts to the PCI-E card 1.the part that plugs into the MoBo 1x and the part that plugs into the GPU 16x Can you plug the GPU with the riser card into a different PCI-E to USB 3.0 card or even better can you plug in your graphics card directly into a USB3.0 port?
Hmm.. I see, I want to get a PCIE extender with a backplate (basically a Pcie Extender which plugs into the back of the PC) We are really only talking about a design change here... do you perhaps know where I could get one of those?
Good idea but you must consider that PSU in such PC is not strong enough for cards that consume much power. GT 710, for instance, is low power consumer and I believe it wouldn't be problem for such PSU. In the other hand, I wouldn't use R7 260 on that PSU...
Thank you for testing this. I am looking at a way to free up an 16X slot on a server. Putting a cheap GPU on a 1x slot sounds like the right idea. At least it is less expensive then buying a new motherboard. Will be running and Ryzen 7 1700 CPU.
Another reason you might do this is if you want to use a full size card because the low profile variant doesn't exist or is too much of a markup, on a motherboard/case combo taht can't take said full size card without a riser.
FYI, these riser usb cards are not meant for gaming. Your supposed to use them for mining and machine learning. For gaming, latency is a critical factor, so you should plug directly in motherboard. For mining and AI, brute compute power is needed. Data isn't moved around as much as 60fps 4K so latency is not a bottle neck at all ... I even think we can connect through a USB hub. But training a neural network with 6 GPUs is orders of magnitude faster than with a single GPU ... dont even bother with CPU, the software libs will get updates while ur still training
your riser is not working properly, example if you order 10 of them 3 or 4 will come faulty, to make sure riser is working properly you must overclock to max and if it works same as pluged in board then is a good riser, and never use added molex to sata converter cause it can burn
2:22 maybe that adapter x1-x16 could be used if you have only 1 pcie x16 and you want to run a old card in sli ,thats 1 reason the adapter could be usefull
So, where people may do this is in a laptop. Its caveat city, but it is a method to equip a laptop with a GPU. That all depends on the PCI-E slot on the laptop which will be x1 and it would have to work at BIOS level.... In this, I would only recommend like a GPU that does not require more power than PCI-E spec - so less than 75w (1050gtx, ti, , 1650gtx, ti, 750ti
The load is mainly on the GPU (evidenced in the Hitman frame rates). If a graphics application is CPU intensive it's because the GPU has to talk to the CPU constantly.
PCIe x16 has 16 full duplex lanes while PCIe x1 has just 1 full duplex lane. USB3.X [cable-only] is just a single full duplex wire, unlike USB’s predecessors, which are half-duplex. Therefore, swapping between x1 and x16 really shouldn’t make much difference as seen in the graphs. The actual differences I would likely attribute to the lane multiplexer, which is what allows some motherboards to have more PCIe slots than others. Finally, USB3 and PCIe data protocols are similar but different. It is like trying to plug an ethernet cable wired with a USB3 head into your computer’s USB port. It wont work. As one youtuber demonstrated, you wouldn’t be able to plugin the USB end of the PCIe adapter into a USB3 port and get instant graphics, that is, without a protocol translator. Basically, a USB cable is being used here but not the USB protocol itself, so there are no USB protocol related bottlenecks. :)
Not a stupid test, its a good test. I checken my laptop with on board graphics, Intel Core i3 with HD5500. The drop in graphics performance is about 8% through the USB3.0.
Actually, it's quite a useful information since I owns a Dell Optiplex 980 SFF. Because the design of the motherboard and the size of the case, I couldn't use a normal sized GPU. Just one question,if you power the GPU via PCIe riser using a seperate PSU, does it impact performance?
You'd use a non usb riser cable and mount the card on the outside of the case, and use an external psu, its possible, and wouldn't effect performance as you'd have full bandwidth.
Thanks this was helpful, wasn't sure if the riser even provided video out on a card. Need to relocate a 4th GPU externally just for running my 4th and 5th screens above my 3way SLI surround setup. Not for gaming just my desktop while gaming. This will work perfect. I have one x16 slot available on my board under the sli bridge and didnt want to cram a single slot card in there to just reduce the airflow I gained from a staggered 3way. 👍
I honestly don't care if it works at all with pcie 1x to pcie 16x via usb 3.0 cable, that's what it is intended for and it should work for that. I want to know if it works if you plug the usb 3.0 directly into a usb 3.0 port.
No way. The USB cable is only used as an electrical connection, the data isn't transferred via the USB protocol at all. You also see ExpressCard to PCIe adapters that use HDMI as the connector, for the same reason that there are enough pins, common, cheap and good enough electrically.
Hi, thanks so much for this test... This helped me alot, busy building a pc where the GPU can't go on to modo and has to be layed on it side. It's not going to be a big gaming pc, but the GPU is going to be used for small/old games and pic editing. Thanks
this would have a use case for someone who has a laptop and would like to game at home, using a riser and a graphics card, without having to purchase a whole desktop.
Take this with a grain of salt ; but I believe unless you are powering from the PCI-E 6PIN 12V Rail you are actually limiting the amount of power provided to the riser card. From my understandings, the PSU doesn't enforce the 75W limitation when using the 6PIN directly from PSU vs SATA or other types of power. The heat seen here could have also been generated by the GPU trying to draw more power than what your Molex was providing to the riser which also would explain the drastic drop in performance/stability. Molex only provides 6~8amps per connector in comparison to the 6PIN which gets about 13amps per wire and draws most power directly from the PSUs 12V Rail.
It's not stupid. I have two 1070's that are different widths, and as such I cannot connect the rigid HB SLI bridge to them. Maybe I can use two of these mining risers to make it work.
Thanks, you video gave me an idea. I have a dh55hc motherboard i5 650 and I could not make a gtx 1060 to work on the main pcie slot. Now with the riser on the pciex1 slot. it works and i can play some games.
All I wanted to know is if it will work connected to the onboard USB port and not that riser like card... but there was too much talking going on... Can anyone just give me a "yes" or "no" answer?
Sounds like your powerdelivery from the riser is fluctuating and pumping to much power into the card causing over heating. If your card hasnt the bandwidth due to the riser or power delivery to the cards pin connectors you wont get preformance of the card
I doing with 2 pcs GTX 1050ti & the performance like have one GTX 1660 super..im doing like this because 2 pcs GTX 1050ti more cheap than 1 pcs GTX 1660 super..and my graphic card is far from motherboard because i modified my own casing so im using one PCle x16 mount for other GTX 1050ti card & its working..but i dont know if using the lian li extender graphic card cable is working or not if we bending it if there your card is not tailing with your motherboard place...lian li extender graphic card is new technology & expensive..so im using the PCle entender like in this video
Ruski I thought the device being used in this video was USB based? I already know that you can use pciex1 risers on laptops but I want to know if there is USB ones that will work on them.
So, this is using a usb3 cord but in actuality its a pcie x1 to x16 riser card, and this is possible on laptops, since laptops have mini pci-e you have to buy a mini pci-e to pci-e x16 riser card and it will work, the downside to this is that some laptops only have one slot and the built in wireless adapters generally occupy this slot, so if you plan on using ethernet or a usb wireless adapter this would work and its done quite often actually. And if you wanted to do it this is what i came up with, with 5 minutes of searching: www.amazon.com/Mini-Express-Extension-Adapter-Riser/dp/B01FVPITN8
Totally possible, actually planning on building a Back up Desktop out of an old laptop I had laying around. With this I should be able to do a little gaming and editing on it (it will require a power supply however)
This works well if all you own is an older Dell or hp with a locked bios because the pcie x16 slot is only 25 watts by adding this you can draw extra power from the molex or sata....I did a few videos on it and it actually is pretty neat...Nice video btw I subbed
Just need to clean the slot out. Proper liquid cooling solution should not short anything. I had the same thing happen to me. I just cleaned the board with distilled water and let it dry out FULLY. Worked good as new.
Clean it with rubbing alcohol - never conductive. Even distilled water will pick up metal ions (everywhere on a mobo..) and become conductive. The alcohol will evaporate, for sure, WAY faster.
Thanks for video. Also mentioned temperatures in graph would be usefull. If I understand you correct then you have riser PCIe1x Male to PCIe16x Female. And you plug PCIe16x GPU to riser's PCIe16x Female and then tried two cases: 1. riser's PCIe1x Male to motherboard PCIe16x Female 2. riser's PCIe1x Male to motherboard PCIe1x Female Am I correct? Thanks PS: can you please post link to riser?
I am a newby into PCIe cards, Would it be possible to connect the PCIe16x directly to a laptop through the USB ports (NO 1x PCIe) although slower ? (I know the PCIe bus is faster than the USB Bus ) Any info/input appreciated. I Just want to use a Data Acquisition PCIe Card with My Laptop
USB 3.0 controller latency is about 20 microseconds. PCI express v4.0 latency is 125 nanoseconds (v3.0 latency is 300 nanoseconds). You should have no further questions about performance.
It's good so you will not go to that direction after seeing the experiment. Thanks, keep on doing video like this to enlighten newbies but if it is for expansion speed is not an issue but video wise decompression and compression with usb is the main factor there.
How come you can use a USB 3 pointer to the graphics card why do you have to use a PCI slot that's my thing I want to do I want to hook one of them of what happened through USB 3 point out it works with thunderbolt what's the difference
Why does it affect some games? Some games transmit more data to/from the video card. 1x port can only go as fast as 1x even if your card is 16x. Why it doesn't make a difference for mining it's because you don't need to transmit alot of data tofrom your video card. I hope I have answered your questions. lol
Only just stumbled across this video. I'm currently running my 1080ti on a riser and i've got zero issues other than multitasking is fucked. It can handle a single game but if you open OBS that's it. My computer just stops. 16X riser is the ribbon you people want.

The 1x slot probably goes through the northbridge chip, so there is extra overhead and latency. The 16x runs straight to the CPU pins.

Could try running them in SLI through multiple pcie usb riser cards and see if it improves it by spreading the load...
Actually, it's quite a useful information since I owns a Dell Optiplex 980 SFF. Because the design of the motherboard and the size of the case, I couldn't use a normal sized GPU. Just one question,if you power the GPU via PCIe riser using a seperate PSU, does it impact performance?
Unknown Blogger I have an optiplex too will be trying this next week
You'd use a non usb riser cable and mount the card on the outside of the case, and use an external psu, its possible, and wouldn't effect performance as you'd have full bandwidth.
Can it will work as a external gpu for laptop ?? as EXP GDC Graphic Card Dock !!
Thanks this was helpful, wasn't sure if the riser even provided video out on a card. Need to relocate a 4th GPU externally just for running my 4th and 5th screens above my 3way SLI surround setup. Not for gaming just my desktop while gaming. This will work perfect. I have one x16 slot available on my board under the sli bridge and didnt want to cram a single slot card in there to just reduce the airflow I gained from a staggered 3way. 👍
Hi Marcio it has been 2 years but did you manage to add 2 screens out of a USB3.0 PCI-E Riser?
I honestly don't care if it works at all with pcie 1x to pcie 16x via usb 3.0 cable, that's what it is intended for and it should work for that. I want to know if it works if you plug the usb 3.0 directly into a usb 3.0 port.
No way. The USB cable is only used as an electrical connection, the data isn't transferred via the USB protocol at all. You also see ExpressCard to PCIe adapters that use HDMI as the connector, for the same reason that there are enough pins, common, cheap and good enough electrically.
SPEAK SPEAK SPEAK.... AND DON´T SAY NOTHING!!! HEELLL
whatchout for amp tollerance on that sata power adaptors, one must maybe stick to the robust molex plug.
would it be worth it for a laptop?
Hi, thanks so much for this test... This helped me alot, busy building a pc where the GPU can't go on to modo and has to be layed on it side. It's not going to be a big gaming pc, but the GPU is going to be used for small/old games and pic editing. Thanks
This is actually a useful test for me, I'm fixing up a old dell dimension e310 and there is no pcie x16, only a pcie x1 and 3 pci slots
this would have a use case for someone who has a laptop and would like to game at home, using a riser and a graphics card, without having to purchase a whole desktop.
Plug the usb 3 into the usb 3.0 slot on mobo while using one directly on mobo see if the crossfire or sli will work at all
Lol sli, they both will have to be in the mobo with the (whatever called) thing that combines both of the 6P/8P connectors
Take this with a grain of salt ; but I believe unless you are powering from the PCI-E 6PIN 12V Rail you are actually limiting the amount of power provided to the riser card. From my understandings, the PSU doesn't enforce the 75W limitation when using the 6PIN directly from PSU vs SATA or other types of power. The heat seen here could have also been generated by the GPU trying to draw more power than what your Molex was providing to the riser which also would explain the drastic drop in performance/stability. Molex only provides 6~8amps per connector in comparison to the 6PIN which gets about 13amps per wire and draws most power directly from the PSUs 12V Rail.
It's not stupid. I have two 1070's that are different widths, and as such I cannot connect the rigid HB SLI bridge to them. Maybe I can use two of these mining risers to make it work.
Thanks, you video gave me an idea. I have a dh55hc motherboard i5 650 and I could not make a gtx 1060 to work on the main pcie slot. Now with the riser on the pciex1 slot. it works and i can play some games.
What speed is it running on X1 or x16?
All I wanted to know is if it will work connected to the onboard USB port and not that riser like card... but there was too much talking going on... Can anyone just give me a "yes" or "no" answer?
hey every one !!
is there a possibility to connect a riser to laptop with usb port ?? please help
egpu
Super test thx, could you plug it directly to a laptop USB port it will be very interesting
By me its work fine its the same as on the mobo 16x No difference. Fps are the same in gaming
could you connect the full size riser to the PC via only the USB connection and it still work?
@wedotech hey does that card work when connected not to the pcie x1 slot, but to usb3.0 via the riser cable?
+eivis13 Not to my knowledge, it needs a connection interface to convert the signal.
Sounds like your powerdelivery from the riser is fluctuating and pumping to much power into the card causing over heating. If your card hasnt the bandwidth due to the riser or power delivery to the cards pin connectors you wont get preformance of the card
You think you could use a PCIe riser to USB to better a laptops graphics?!
Connecting two different GPUs how would it perform?
I doing with 2 pcs GTX 1050ti & the performance like have one GTX 1660 super..im doing like this because 2 pcs GTX 1050ti more cheap than 1 pcs GTX 1660 super..and my graphic card is far from motherboard because i modified my own casing so im using one PCle x16 mount for other GTX 1050ti card & its working..but i dont know if using the lian li extender graphic card cable is working or not if we bending it if there your card is not tailing with your motherboard place...lian li extender graphic card is new technology & expensive..so im using the PCle entender like in this video
Is the PCI-E working if you plug it in a USB 3.0 port?
Does this External Riser work with a sound card? Like a 7.1 channel sound card?
Is it possible to use one of these on a laptop? I'm probably not going to do it myself but I'm just curious.
Jordan Brown I want an answer but I don't think anyone is mad enough to try
Ruski I thought the device being used in this video was USB based? I already know that you can use pciex1 risers on laptops but I want to know if there is USB ones that will work on them.
So, this is using a usb3 cord but in actuality its a pcie x1 to x16 riser card, and this is possible on laptops, since laptops have mini pci-e you have to buy a mini pci-e to pci-e x16 riser card and it will work, the downside to this is that some laptops only have one slot and the built in wireless adapters generally occupy this slot, so if you plan on using ethernet or a usb wireless adapter this would work and its done quite often actually. And if you wanted to do it this is what i came up with, with 5 minutes of searching: www.amazon.com/Mini-Express-Extension-Adapter-Riser/dp/B01FVPITN8
Totally possible, actually planning on building a Back up Desktop out of an old laptop I had laying around. With this I should be able to do a little gaming and editing on it (it will require a power supply however)
Khalid, Thanks man! looking back on my comment I got kinda side tracked and didn't fully make it clear, you said what I was trying to :P
Can we use this method for streaming as adding a second GPU for obs
I wonder what your PPD would be in Folding @home...
This works well if all you own is an older Dell or hp with a locked bios because the pcie x16 slot is only 25 watts by adding this you can draw extra power from the molex or sata....I did a few videos on it and it actually is pretty neat...Nice video btw I subbed
happened to me. watercooling leaked into x16 slot. card fried. got new card but slot was dead. rest of mobo ok though so i could have done this.
Just need to clean the slot out. Proper liquid cooling solution should not short anything. I had the same thing happen to me. I just cleaned the board with distilled water and let it dry out FULLY. Worked good as new.
yes i should have tried that. luckily i now have a totally new system.
Clean it with rubbing alcohol - never conductive. Even distilled water will pick up metal ions (everywhere on a mobo..) and become conductive.
The alcohol will evaporate, for sure, WAY faster.
i watched a video where a guy cleaned a mobo in the kitchen sink UNDER THE TAP! it worked!
My x16 slot doesn't work. Mobo is a hand-me-down
Thanks for video. Also mentioned temperatures in graph would be usefull. If I understand you correct then you have riser PCIe1x Male to PCIe16x Female. And you plug PCIe16x GPU to riser's PCIe16x Female and then tried two cases:
1. riser's PCIe1x Male to motherboard PCIe16x Female
2. riser's PCIe1x Male to motherboard PCIe1x Female
Am I correct? Thanks
PS: can you please post link to riser?
your gpu-die is right next to the PSU, that's why it's running so hot.
So like 1 in a thousand? Oh, more like one in a million. So you're telling me there's a chance! Yeah!
I am a newby into PCIe cards, Would it be possible to connect the PCIe16x directly to a laptop through the USB ports (NO 1x PCIe) although slower ? (I know the PCIe bus is faster than the USB Bus ) Any info/input appreciated. I Just want to use a Data Acquisition PCIe Card with My Laptop
Ashes of the Singularity using multi GPU and risers. DX12 multi GPU will be the future.
I wonder if it would work for blender rendering, coz it doesn't really need to output any graphics to the screen, just internal stuff
Maby, it works for mining so why not blender.
USB 3.0 controller latency is about 20 microseconds. PCI express v4.0 latency is 125 nanoseconds (v3.0 latency is 300 nanoseconds). You should have no further questions about performance.
what about having sli on a board with one pcix 3.0 and a pcix riser for a second gpu
It's good so you will not go to that direction after seeing the experiment. Thanks, keep on doing video like this to enlighten newbies but if it is for expansion speed is not an issue but video wise decompression and compression with usb is the main factor there.
You great. I got what I wanted. Note, not everyone is a "letgo"... Could have deeply gone into practical than the talking theory.
on the riser there are 6 pin power whether we have to use sata to 6 pin power or I can use 6 pins in psu
This mini pci-e suitable for laptop?
I’m researching this thing because I want to mod a Mini STX case and add another compartment to house a small form GPU
now my question is does it work on my old laptop? (toshiba tecra a10-1ll)
is there a way to get a adapter for PCIE to mini PCIE, my computer has a mini PCIE slot but the GPU i have is a normal sized PCIE.
Could you run crossfire or ski with that adapter if you only have a x1 and x16 slot?
so what about the pci-E mini card socket ?
What montior is that? It looks good. Is it that 250 hz monitor you reviewed?
Yeah, it the PG258 240hz monitor. The review will be out next week.
How come you can use a USB 3 pointer to the graphics card why do you have to use a PCI slot that's my thing I want to do I want to hook one of them of what happened through USB 3 point out it works with thunderbolt what's the difference
ciao ottimo video una domanda e compatibile con tutte le schede video o solo alcune ? potrei elencarle ?
grazie
Why does it affect some games? Some games transmit more data to/from the video card. 1x port can only go as fast as 1x even if your card is 16x.
Why it doesn't make a difference for mining it's because you don't need to transmit alot of data tofrom your video card.
I hope I have answered your questions. lol
Using this with a Laptop is actually nice
What test bench case is this please? Thank you.
Only just stumbled across this video. I'm currently running my 1080ti on a riser and i've got zero issues other than multitasking is fucked. It can handle a single game but if you open OBS that's it. My computer just stops.
16X riser is the ribbon you people want.
