I bought one from Amazon and it worked! I had to snake the riser cable below the GPU, then above the next slot's PCIE card, then down again. The riser cable was only 200mm so it was barely long enough. The motherboard and the other PCIE card (Optane U2 SSD) were blocking the riser cable's PCB a little bit, so mounting the wifi PCIE card was a little bit crooked and didn't line up with the case. However the screw went in and the antennas still kind of screw in so all is good.
Nice - which cable brand did you end up getting? The riser cable length is a bit tricky to plan for - that's why I just bought differences sizes to figure out what works. The clearance is really tight, everything has to be just perfect to clear, but it sounds like you managed to get your wifi card mounted. No complaints - now you have wifi!
Thank you for your feedback. I provide a detailed video index in the video description so you can skip to the relevant parts as desired. The video structure is to ensure that anyone can reproduce the process and understand how to troubleshoot it - rather than just making it a short vid with a cool PC mod without any info on the limits of the process etc.
Had to solve this one too while modding an original Cooler Master HAF case; pciex4 riser to usb3.0 card, utilizing the vertical single slot where a water cooled GPU would have went! 😆
That's great to hear. The riser adapters sure come in handy. Did yours manage to still fit inside the case? I think with one riser adapter here you can still close up the case. Yours wasn't the Cooler Master HAF X case by any chance? I still have one in the family! Solid tower even by today's standards.
@@racerrrz Yep! Mid-tower ATX; painted the inside flat black, outside beige. Cut the bubbled side panel out and replaced with pet-proof window mesh for maximum airflow. 7" raspberry pi touch-screen where the 5.25" drive bays use to be and de-riveted internal cages. The USB 3.0 card and 3060 TI are both vertically mounted!
@@techromancer313 That's cool, even more so with your case being a HAF X! Your system sounds well tuned. The touch panel in the case makes for a nice upgrade to modernize the case and to add that custom look. Add in the two vertical risers and you have a solid case there!
I'm glad I found this channel, I have the exact same workstation z840 and I can't believe that such improvements you are made like video cards upgrades and various adapters for storage. Amazing content. Thank you so much! By the way what you recomend beter for my Quadro K5200?
Thank you for your feedback and support. Nice going with the Z840, they are solid machines for the price point. Being able to load in several PCIe expansion cards really opens up the possibilities for customization. I am quite satisfied with my quad RAID 0 NVMe adapter setup - awesome speeds and capacity for such an aged machine. In terms of workstation GPU, the one I like best from a value perspective is the NVIDIA RTX A4000. They have 16GB GDDR6 with ECC and a small footprint / power draw requirement. If you plan on gaming at all it would be better to get a gaming GPU - something like the RTX 3080 is quite solid. I settled on the RTX 3090 Ti for the added VRAM for video editing.
@@racerrrz Thanks for the detailed answer. I use this computer for 3d printing like slicer programs or cad programs, less for games.I have had this computer for about 3 years. Hp z840 parameters are: x2_Xeon e2667 v3 3.20ghz / 128gb ram / Nvidia quadro k5200 GPU. I think I should expand the amount of RAM and get a better video card. I need to watch all your videos related to the improvement of this computer. Thank you
@@andriusanryy5165 Nice, the Z840 really handles it self well for CAD applications. I had the E5-2667 V3 for a long time, solid performer. You may want to check for a matched pair of E5-2697 V4's - the used Broadwell prices are quite good at the moment. If you want max core count - consider the E5-2696 V4. The CPU upgrade would allow 2400MHz ECC memory modules also, but RAM is still quite pricey. If you are running short on memory it's worth the expense. The GPU upgrade should improve your productivity the most. I quickly compiled all my Z840 videos into one place to make it easier to cycle through them. My website still needs a lot of work but here is a sample: racerrrz.com/hp-z840-hub/
That's true, and I wish more videos just got to the point instead of dragging things out. In my defense, I aim to add in as much value as possible into each video and I do aim to keep only what I deemed to be relevant to the audience I believe will be interested (with a large number of my subs being fans of the HP workstations - hence the PCIe slot optimization early on in the video). I always include a detailed video section index in the description (allowing quick skipping to the solution), and more recently I have started including my own video content index in the video footage to help viewers more effectively navigate through my tutorials. Time is precious.
Good question. I have a detailed outline on how to do that in this video: th-cam.com/video/D1cwwiR4UHM/w-d-xo.html (check 12min 24 sec and the video description for that video for the adapter cables you need). I converted the 6-pin GPU power cables to 8-pin GPU power cables by using a 6-pin to 8-pin adapter cable. Normally for ATX PSUs the 6-pin cables are limited to 75W and the 8-pin cables are limited to 150W. HP over-engineers their PSU 6-pin power cables so that they can supply 219.6W (nearly 3x more power than industry standard for 6-pins!). This is why you can adapt the 6-pin cables to 8-pin cables. If you did this with an ATX PSU you will fry the ATX PSU - so it will only work with HP workstations (in particular) due to the over-engineering.
lol, I had same problem with my workstation Dell t7810 with 2 x Xeon and 2 Nvidia Tesla . My solution to install the second Nvidia Tesla was the same :) I installed the reiser 30 cm with angle 90. I replaced the side metal panel with plexyglass panel and cut a slit to pass through the reiser cable. I printed with printer 3D the GPU holder and now the GPU works on the plexyglass panel, outside the workstation. I also installed a 1000w sfx power supply only for the 2 Teslas and obviously a 2addpsu module to turn on the second power supply :)
Well done, they say great minds think alike and by that logic I applaud your ingenuity. The tolerance under the GPU is quite limiting but certain GPUs would have more clearance than others. Great thinking with the 3D printer also - finding a way to get these adapters to mount remains a tad tricky. My cheapest logic was a longer riser cable that would allow the adapter to be routed to a new location inside the case. Had my GPU power cables fit inside the case I likely would have worked on a method to mount the riser extension above the GPU / on the GPU backplane. The extra external power also helps overcome the limitations of your T7810 system.
I am using the same technic, to use ALL slots on my MSI B450 motherboard, because I have dual slot GPU, PCIe WiFi card, PCIe x4 SSD, second single slot GPU, for DVI monitor, and PCIe sound card, because the integrated Realtek chip failed.
Nice! Which PCIe riser cable did you use for yours? I have not found many that actually fit underneath the GPU. I applied the same logic in my Z440 server built - all 6 PCIe slots are in use - but at least there I had a PCIe riser build into the case to mount the GPU. It just makes sense to get the full usage out of your motherboard!
@@racerrrz I used PCI Express x1 riser 25cm from Aliexpress, to connect my sound card and mount it vertically. I was able to bend the cable, so that it can pass under the GPU.
Good question. I would be inclined to say spend a bit more to ensure you obtain a quality piece. I ran into issues with the cheapest riser cable - it caused a PCIe fault and lead to the adapter not working (I covered that and troubleshooting in the followup video to this one: th-cam.com/video/5tQct_LxPjo/w-d-xo.html , 9.58 in the video). Looking at the PCIe card (USB Type C Adapter), I think the riser cable fried capacitors on the adapter (there was leakage from them). In terms of a review of riser cables, I don't think any one has done that. I would recommend getting the highest quality item you can obtain for the lowest possible price. I plan to get a Lian Li Riser cable (PCIe 4.0; PW-PCI-420) for that reason.
The motherboard would handle the dual RTX 3090's but the PSU does not have sufficient power cables to power them. The max GPU power available is 3x 6-pins that supply a total of 685.8W (3x 219.6W; 12.2V @ 18A per 6-pin). The HP Z8 G4 might handle dual RTX 3090's - it has a max GPU power available of 878.4W (4x 6+2 pins at 219.6W each; 12.2V @ 18A per cable). The only limit is the number of cables - your GPU would need to only require 2x 8-pins for the Z8 G4 to support dual GPU.
Hi, yes it should be quite feasible. A quality riser cable plus a secure GPU mount will do the job well. If you were really keen to push things you could get a couple of the modern GPUs connected to the Z840 with riser cables (powering both of them will need an external PSU also). It gets messy but there are options!
You can trying using pcie3 x16 expansion backplane with chassis such as 'netstor' 'datapath' 'one stop systems' etc. Then you can close Z840 door with big GPUs without stress for fitting. But your poket will.... gone empty💸
Hi there. Those are some really impressive PCIe expansions and it can really open up possibilities for some $$$. There doesn't seem to be all that many solutions to the sheer bulk of the GPU - but the main fix I was been working towards as an E-GPU based configuration (so an external housing with at least 3x PCIe 3.0 slots, but they tend to only have 2 slots) or case swapping the Z840 motherboard. I plan to test out a Z840 case swap and so far I can power a Z840 motherboard outside the case / independent of the OEM PSU. But for now the open case is having to do. Dust build up is an issue but thermals are staying good on everything at least.
I'll admit that it's a somewhat underwhelming PC mod, but at the end of the day I get to use PCIe slots that are normally lost to that all GPU bulk. I see that as a win.
Yes there was a lot of that.lol. In hind sight I spent far too long on adding in effects (I recall some effects taking hours to get right), but I guess that gives each video it's own feel - good or bad. My more recent videos have substantially less effects, but each video still has some new editing trick that I test out.

How to give power to the GPU? I only have 6 pin connectors, but I need two 8 pin connectors for my GPU
