- RTX 3090 Ti SLI: Bad Idea or Worst Idea?
⇨ Sponsor: Corsair K70 RGB PRO Keyboard | buy/more info: bit.ly/PHCorK70
After NVIDIA launched the GeForce RTX 3090 Ti last week, I decided to try 2-way SLI because I ended up with 2 cards -- the MSI Suprim X RTX 3090 Ti, which I reviewed on launch day, and the Palit GameRock RTX 3090 Ti which I'm using for an upcoming build tutorial. Here's what happened.

Hey All! TY very much for watching 🙏 I just wanted to update that the reason my 12900K SLI setup didn't work is very likely (almost 100%) due to the Maximus Z690 Hero Motherboard not having an SLI Key -- apparently only a couple ASUS Z690 boards like the Extreme and Apex have SLI support. This is a big change from prior generations going back 10+ years where pretty much all "Z" chipset Intel motherboards had SLI/Crossfire support. Many thanks to those who commented with that info -- DEJ915 and Beyond4k here on TH-cam and @Purgatory_Nabil on Twitter, as well as others I might have missed.
Now that's shitty. But somewhat comprehensible, since SLI is on vital support... only 2 GPU's and only working on 3Dmark AFAIK.
I'm betting that the 40 series cards will mark the end of SLI all together. As an enthusiast this is sad, but we gotta understand how impractical it was since its inception in 2006😂😂
F
bout time you got around to it...th-cam.com/video/q9w3PEVwezw/w-d-xo.html
JK love you Paul! Huge fan of your work!
I would just like a 3060Ti but that isn't even attainable...
I love this. Almost $5000 worth of GPU supported on blocks.
And still safer than letting Linux hold one!
"worth" is very loosely used here. Maybe cost would be the best word
@@d2ricci Exactly, worth about $300-400 in parts + dram + the silicon which they likely pay a similar price for, they just charge AIBs 300% of that price, passing it on to us.
Arguable you forget R&D ect
You haven't priced Legos recently? That's probably $3500
You little war with JTC with overclocking the 3090's was probably one of my favorite tech video series I've seen in the past couple years. I'd love to see your crazy attempt at beating your own score. They're fun videos to watch, and I imagine they're fun to make, too!
I thought it was called the RipGN series on JTC? I had no idea there was another identical competition between Paul and Jay.
@@Gimpy17 it was 3 ways, RIP GN, Jay and Paul.
@@mrthesquid well damn, looks like i have some more OC vids to watch lol
@@Gimpy17 I jumped in with them a couple times but I was never a long-term contender, eventually they go LN2 which I haven't touched more than a couple times. Ice bath was as far as I went with the 3090 SLI setup but it wasn't very successful. We'll see how things go with 40-series though! Who knows 🤷♂
@@paulshardware insider knowledge confirming 40 series is just around the corner? 🤔🤔😊
Paul, the reason SLI didnt work with your intel rig is because asus didnt purchase an sli license for the majority of z690 boards. Take a look at the ROG forums and lots of folks had to complain for months to get SLI enabled by asus on at least some boards.
Well who woulda thunk that Nvidia's greed and Asus' penny pinching would lead to much headache in trying to get sli working. Luckily MSI to the rescue
Thanks for the heads up, I had missed this but it almost 100% has got to be what kept it from working. I have other motherboard (and CPU) options to work with fortunately!
@@paulshardware Yep, the APEX has it and mostly all MSI boards have it
@@danielmonsanto8286 yeah, well sli is effectively dead, so it's mostly a non-issue
@@danielmonsanto8286 Why do you even blame Nvidia for greed? Pretty much Nvidia gave up SLI as DX12 has multi-GPU support, but devs of many kind must implement it.
I sense you're an Aymdiot fanboy.
I miss SLI. It was a crazy time to be a PC enthusiast.
what?
i had a sli voodoo2 back in high school fam.
it wasn't crazy.
@@mongoosemcmongoose2786 in English, "crazy," can also be a good thing.
Yeah probably means crazy as in freaking epic not crazy as in absurd
@@mongoosemcmongoose2786 "a sli Voodoo2"? Do you mean a single vide card or you had two? You said a sli Voodoo2 rather than saying you had Voodoo2's in sli.
In 1998 Iwas a younger man, but I also had a set of Voodoo2 cards in SLi. They were pretty awesome. So I can relate. Games looked so much better with 3DFx rather than D3D or OPENGL. Glide was the way to go.
@@mongoosemcmongoose2786 remember when the 5k 6k voodoo's finally came out super late. That was kinda sad
The thumbnail choice is brilliant 🤣 thanks Twitter and Paul.
In other news, GPU vendor Nvidia has unexpectedly purchased three air conditioner manufacturers. White nosed Wallstreet analysts are saying that they believe Nvidia is playing both seasons of the home climate control market. While annoyed gamers in Florida are making the argument that modern GPUs have made gaming rooms more uncomfortable than ever during the summer. We were able to reach an unnamed but also unconfirmed employee at Nvidia R&D who says that Nvidia will be offering free home installation of a second air conditioner for buyers of the RTX 4000 series.
There are also rumors of an Nvidia/Enron partnership which will enable users to utilize GPU waste heat for the production of electricity to run the Nvidia air conditioner. The before mentioned powdered analysts predict this heat capture could also power blockchain innovators. "This is the biggest synergy and paradigm shift of the decade, this will make decentralized power the new normal, allowing us to circle back and pivot to unprecedented and diverse energy solutions." The US Department of Energy has already given Nvidia $6,000,000,000 of free cash because Nvidia is a very poor company that can't afford to invest in its own ventures. Luckily Nvidia won't have to repay this cash if they fail, or if Jensen Huang decides one day, "nah, I don't feel like doing this."
For years shill reviewers attacked radeon cards even sparking memes about power use and poor drivers. Even Toms Hardware reviewed an r9 390 (a poor twin fan SKU version they used BTW) and gave it a devastatingly bad write up saying it was hot, thirsty and loud. (They did not tweak it at all, which most buyers would even to find a slightly lower sweet spot)
The impression given was this was the case for the gpu chip in general.
Yet all these years later the 390's still perform enough to be useable in 1080p gaming.
(The nvidia 7 series competition does not)
Jenson; 'It just works' ( ignoring space invader R.E.M.'s) and
'The more you buy the more you save' !
Gordon Ung talking mid price gaming build options and I quote;
"Vega 56? (shakes head and feigns disgust, barely resists holding his nose;)
Noo, FAR Too Thirsty! "
Yet a vega 56 can be undervolt tweaked fine for a 550 watt bronze psu and perform better than stock.
Let us ignore tweaking and go with stock settings, even now some sites show bias;
www.realhardtechx.com/index_archivos/Page362.htm
The 3060 TI (best bangs / $ 30 series card) is listed as requiring a '575 watt' psu (do you know anybody who makes one?)
Are there any '575 watt' power supply requirements on the other side of that chart??
Is stepping down to 25 watt increments not acceptable for Radeon cards?
Considering nvidia have been talking about upping psu quality for 30 series to gold (effectively a 5-8% psu size requirement reduction) I would say something fishy is still well afoot.
When I look back at all the memes spewed forth about GPU power use yet now Nvidia says you need to upgrade a perfectly decent bronze 650 unit like a 2019 cx 650 to run a 3080 (an rx 6800 it would fine)
I have to call B/S.
I recently bought a half price retail outlet bargain XPG 650 core reactor gold, 10 year warranty (full warranty, NIB, bad marketing good quality unit)-
but if Jensen thinks I will be buying a gpu card that wont run on that psu like the 3080 he is off his fxkc1ng CHOPS!
Jensen went to Samsung, cheaped out on the node and now expects me to pay through the nose for a bigger gold psu to make up for it? I should fxkc1ng coco;
He can k1ss my hairy 4rse!
This is an underrated response. I genuinely chuckled at all of the references, which means I'm old. I'm sad now.
Quality sh*t posting sir, hats off to you!
I think that is the first time I've ever heard anyone say "1600 watts should be enough, I hope"
haha, so true. also hillarious that he had to turn all the other stuff off.
The only Asus boards with SLI key are Apex, Extreme and Extreme Glacial. MSI has some and EVGA does too. Shamino confirmed that the Hero will not be getting an SLI key so if you want to use SLI and 12900k you need a different motherboard.
Silly me thinking that Z-series motherboard would = SLI support like it has for 10+ years 😭 this definitely seems to be the answer, many thanks for the information. I missed the SLI key situation.
@@paulshardware Yeah it's a bit of a bummer, I guess they figure it's an "enthusiast" feature but at the price boards at now you'd still expect it.
Another reason that didn't help was the fact that Nvidia did not hand out the retail SLI keys until like January, leaving MB companies with the option to A) Not include SLI in bios until this until the receive them or B) Illegally use the internal test build which I can tell you ASUS did not do, but at least 1 manufacturer did haha
@@paulshardware You can get your hands on a 12900 K *S* right? That may give a slight bump?
@@gtijason7853 let me guess asrock?
Paul, make sure to open the windows on that 2nd card support for more airflow. 👍🏻
pisss on it like you're cooling a mortor tube off xd
lol that must be what caused the higher temps
Definitely push this more, loved the competitions with you, jay and steve, we want more!
Too bad we can't quad SLI them 🤔
I usually test minecraft with that setup 😁 From my understanding though, Quad SLI would be Two 2-GPU cards (like GTX 690) and 4-way SLI is Four single-GPU cards. Knowledge that's becoming less useful every day lol
@@paulshardware the more you know!
you getting the new thread ripper pro?
@@Joker-no1fz or the 5800x 3D
@@rileyplatt he has a 16 core threadripper so that would be a downgrade.
Another awesome build! 🔥
There's always such satisfaction watching it build and the final finish where you power it on and say, "It works!" 😆👍
2023, the year Lego release a PC case series: Technik (ideal for open loops), Classic (also available in beige) and Duplo (an entry level case with funky colours and a Hawaiian theme). A big selling point is the availability as ITX but with additional blocks that allow the case to be resized to perfectly fit the PC build.
Awesome video Paul! Best use of children's buildin blocks I've ever seen! Would love to see what you can get with the A/C blowing on them!
"...my daughter's building blocks." I love it.
Yes, keep it going! I'm a sucker for competition though, especially when its not costing me anything 😅
Jensen Huang: Introducing, RTX 4060, faster than RTX 3090 TI, it just work.
19:32 The Steam hardware survey popping up after you finally got SLI working on two 3090tis... perfect.
I am surprised to see SLI still existing. I can't imagine it works any better than it did ten years ago which was.....not great
I don't know much about SLI but why are they bad ? It seems that 2x GPU would be better than 1.
@@Modelo646 It's prone to having weird rendering and performance issues. This was back in the day but SLI seemed to also introduce stuttering in some games.
The big one was frame time pacing and timing. Often times frames times were like 30ms, 5ms, 30ms, 5ms....so yeah you double your frame rate if you count frames but every other frame ends up essentially being a copy of the previous one and you're still waiting 30ms for the ones that matter.
It never really worked right and considering that SLI/crossfire is never talked about anymore I can't imagine the problems were solved. It's bad enough that I knew people who tried SLI but decided to just not use their second card because it made the games play worse.
@@odizzido So basically if you want top performence just buy the best gpu oike 3090 and don't think of SLI. Unless yoy want to flex.
@@Modelo646 SLI in RDR2 works well, in that it's fast if not ideal scaling by any measure, but outside of a few games its not ever really supported
@@Modelo646 the main reason that sli failed is due to lack of support.
I tried 3090 SLI for sh-ts and giggles since I had a pair of them, right before the original launch (one for each of the main rigs), but so few new games supported it that it wasn't worth it at all (and the older games that did were pushing >400 FPS at 4K). The benches were crazy, though. My plug in Taiwan got me a 3090 TI a few weeks ago and asked if I wanted a pair of those this time, but I decided not to bother.
Love it. I know you can't answer but I have to wonder if the unnamed hardware you just received might be a 5800X 3D and I'd love to see that pushing SLI.
Love the fact that Paul is still reporting and building on the latest tech and platforms from his garage!
so your motherboard did not have sli certification in it i'm guessing ? It seems to be a thing that is being mentioned in some motherboard specs, either sli or crossfire certified.
I contacted nvidia with this same issue. It is the mobo manufacturer. ASUS ROG Maximus Extreme z690 works with SLI. The Gigabyte Aorus z690 Extreme did not work so I returned it for the ASUS. Now I'm in 3090 ti SLI heaven. Even motherboards from the same manufacturer dont all have SLI capability.
"Now I'm in 3090 ti SLI heaven."
For what purpose though?
@@k3nny111 for me its simply is fps values. I have 3 240hz monitor and I want my games to reach or exceed that mark while having all the details of higher settings.
S-Tier video!
The building blocks are PC-modding supreme! I also love how you always suck us in deep into your little failures, so funny. Keep it up!
30k or bust! ( Bonus points for taping $4,400 worth of hardware together ;-) )
A great video Paul! It brings me back to when I dabbled with SLI of my 1080 Ti's
2or 3way?
So up to 960W power draw just for GPU's (480W each). Thats a huge amount of power. But it looks like they only hit a max of 408W each which looks to be like they are not running as fast as they could. OR at Least the MSI card.
When the 16 pin plug comes out they’ll jump to 600watts each!
@@frizzlefry1921 Its 12+4. the 4 pins can only transmit information between the psu and gpu to make sure that there is enough power.
@@colindavenport2619 yeah 16 in total.
7:05 Duplo making the ultimate pc test bench 🥰👍😇
Ah SLI. Always remember getting back into PC gaming and getting two GTX 580s on the day they came out. Good times
Tuning in for the memes. And the absolute absurdity of it.
I love AMD X570. Great video Paul.
Works only on "low end" GPUs; 2 x 3060 = 3090 ti
Awesome!!!! I was wondering if we would see sli port royal attempts with the 3090ti and here it is. Great job and persistence to get a result, never give up on 1st or 2nd attempt. Congrats on the new result/rank. Ps:love the toy brick solution to position the cards
3090ti are bad idea especially when i saw that 5800x3d+3080ti beats 12900ks with 3090ti in Tomb rider and probably it will be in some other games too
There’s no way that’ll happen in a graphically intense game…
@@dilet1114 in graphically not but in cpu one it will be and tomb raider are or those part cpu bound
If that hardware he can't say anything about is the 5800X3D, supposedly the fastest gaming CPU in existence, I am very excited to see what these GPUs can do with it. #ripgn
Isn't the 12900ks also coming out soon?
Depends on the game.
Csgo is not one of them.
@@kevinsedwards Because stacking dies vertically requires the fab making them to design the die specifically to be stacked. It's a delicate process that TSMC is still perfecting, with AMD's help.
They've been working on it for years (Ryzen 3000 would have had it if it was ready. AMD has confirmed those chips have the microbumps needed to connect the cache to the CPU, just like all Ryzen 5000 chips do), but up until this point, it was too fragile/expensive/uncooperative/whatever to work.
They finally got it working enough for use in consumer products, but it's _still_ not perfected, as you can see from the fact that AMD doesn't allow you to overclock the CPU to protect the extra cache, but has promised this is the only V-cache Ryzen you won't be able to overclock.
TL,DR - This is a revolutionary technology that required a whole lot of work to get right, and still has a little ways to go.
Cracked up when he pulled out the building blocks, can't wait to see more on this.
Keep plugging away you deserve to go up that leaderboard, I think you achieved wonders in a short time as you are working by yourself having to fit it all in with family commitments.
If only game devs would just patch their games to support sli. ;(
It’s just tech. Anything temporal does not work with multi gpu. Meaning TAA and anything based on it like DLSS2.0 or FSR2.0 or TSR.
reminds me of content from the good days, would love to see ya try to move up the list
Using the toy blocks was genius
I wonder if I will find anyone here who is a veteran of the Voodoo 2 SLI from back in the day. It feels like yesterday when I had that
Lucky you got direct access to the power plant to be able to power two of them at the same time.
Nice experiment Paul! This is INSANE sir!
Man I'm not a big fan of the encrusted look on that gamerock card xD.
Also what a glorious way to handle the spacing issue. I'm in awe of your improv skills lolol
Love the persistence and hell yeah round 2, you could see the fun you were having (and the frustration but that's the fun of it), and my guess is you would love to do another round to get up in that top 10!
What an insane amount of power. Here I am rocking a 3070ftw and playing most games on high!
I'm not a big reply-er to vids but when you have the cards... Even if you don't have much time... Please try to get your ass higher up the board Paul!
I think I'm not the only one that thinks that you are the most 'likeable' character in the TubeTechspace and you deserve a higher place on the board.
I really like the way you present everything... From the buildvids to the news and I'm always checking for new vids on your channel when I go on the Tubespace to get my daily dose of Nerdgasm.
Whatever you do... I wish you and your family all the best and I'll be looking forward to your next video.

Me when someone wants to do a RTX 3090 Ti SLI setup: Do you want to blow a fuse in every house on the block?
Please do another video on this! I miss watching everyone's gpu overclocking videos! They are my favorite!
Awesome. As the iChing used to tell me (way back in the mid 1960s ... and yes, I really am THAT old 👵, during my self-introspection era) ... "perseverance furthers".
When you get the 12900k setup running on the EVGA board, try enabling GPU Multi-Monitor in the bios and install uhd drivers to give you a little boost in your score. Thank Greg Salazar for the sweet tip. I just watched his NZXT Creator video after this and saw him talk about it. I'm pretty sure it could definitely help you bump those numbers up.
Definitely need a part two for this video. Thanks Paul.
I still remember watching you on NewEgg. You've come a long way.
I love the Mega Blocks test bench extension. Parent life, I guess haha.
Stopped by for some potential 3D-printed wizardry, stayed for the legos.
did I see the lights dim in Southern Cali this morning.... ah yes, Dual 3090ti... Nice!
@der8auer I wish both of you expose both Threadripper and intel in the matter of compatibility and benchmarking this beast in SLI !
Both with everything related to gaming:
Vulcan
OpenGL
And DX!
maybe it is not about the end result, but the friends (us) you made along this journey!
i had this issue with my old 970s, both were zotac, same model and both physically identical: this was zotacs responses: Hi,
288-1N366-040Z8 will only SLI with cards with the same PN and also other competitor products. 288-1N366-020Z8 and 288-1N366-000Z8 can only SLI with each other or a pair of the same PN.
Kindest regards,
Eurotech Team
This is the nature of computer parts where ut will constantly be upgraded/updated with newer components. The 2 products were made more than 1 year apart and they both work individually and will SLI as an identical pair. No backwards compatibility is conveyed.
Similarly car parts are defined with different years as they may look the same but does not actually fit. That is why we have different PN and SKu numbers.
Kindest regards,
Eurotech Team
Wow….so much work for SLI. However, I wonder if two 3090ti cards with water blocks can help those scores. I don’t even want to imaging the amount of time and headaches to build a water cooled dual 3090ti rig….! Thanks for the video @Paul’s Hardware!
I was a deer in the headlights of this video. Lots of fun!
Nvidia doesn't still require boards to have official support, do they? Wouldn't be surprised if some boards don't anymore with how dead SLI is.
so im only 4.30 into the video and already this is looking a heck of a lot like a jay2cents rig. FREEKING AWSOME LOVE IT. don't spill you beer this time Paul.
Woa, Paul comes up with a new case design on the fly!
Colorful, very high modularity and even ability of shapeshifting!
The buildingblock case!
Amazing!
Going for oberclocking scored with high end gpus especially in SLI is some of my most favorite videos to watch. I’m there with you with fingers crossed saying “come on, COME ON”!! So yes PLEASE! More of this and maybe even try to get your hands on two 3090tis with built in AIOS. Then spend some time oberclocking and I bet you can break 30k….you can do it Paul! I believe! I BELIEVE!!! DO IT DO IT!!’ Some of the most fun videos to watch’n
My Favourite part of the build is the plastic building blocks!
Go for it Paul! Is always fun to see and i bet you are having fun too!
I loved the last time when you cooled with the janky A/C setup, would love to see that again!
I absolutely love your makeshift test bed risers and set up for this monster. LMAO! Well done, Paul!
Did you forget that the motherboard itself has to support SLi regardless of how many PCI-E you have? You can't just use any random motherboard for SLi, it has to have the SLi in the spec sheet.
Good stuff as always.
As for all the SLI issues....ya know @nvidia, it would be REALLY AWESOME if you could...ya know, put some BASIC logging and UI indicators for SLI and show why it can't be enabled, instead of forcing people to pull their hair out GUESSING why it won't do it. Just a thought...ya know, software is usually able to do basic stuff like that in 2022. ;)
jealous of the guy whos watching this months from now who can just click on part 2. This beer is for you homie
The "Game Rock" on that card uses the exact font as Guitar Hero hahahaha
The Palit is such a beast. It's PCB is on the level of a HALL OF FAME and KINGPIN but much much cheaper!
Thanks for putting a smile on my face today Paul.
"Oh my sweet, merciful Gaben" - Absolutely legend response lol
That support system is epic!
¿Por qué no los dos? La pregunta más bien es ¡¿Por qué las tarjetas siguen TAN CARAS?! :'(
Sorry, I had to do the spanish line seizing the Thumbnail. Despite in some places the prices are getting lower, Taxes and Tariffs still are ruining the prices
This was such a fun vid to watch absolutely try it again!
magic happens when you use a MB that has sli support lmao asus offical statment only apex extrem and extremglacial have SLI support (and only after certain biosversions)... reading helps ...rofl :D but its good to know that even people in the tech industry get confused regarding sli AND that reading manuals is overarted ;)
one of the best videos I have seen Paul ... just a great journey and so good that you shared the frustrations and problem-solving along the way .... thank you thank you thank you from Andy in the Scottish Highlands
Go back for it!!!!!!!!!! Climb the board
Always fun to see you try overclocking.
That Maximus is just stunning lol I was staring at the motherboard the whole time
I came for the “12VHPOWER!” I did not leave disappointed.
Yes! Love this project!
For people that missed the text early in the video, there are SLI bridges to accommodate 2 & 3 slot on water, and other 4 and maybe 5 slot variants. I know because I had to hunt down a 3 slot PNY NvLink Bridge, for Quaddro A5000 / A6000 Spec cards, as I was unwilling to compromise my Asus Glacial STRIX 3090 SLI build. I found a small local shop that actually had been stocking them. I paid $280 then, but it appears they are easy to find now for $200... yes, just for the bridge.

Woohoo! Congratulations Paul, nice job! That was fun to watch.
I don't really understand how... but I love how Paul can be so calm and cool - at the same time as being so hilarious!...
Yeah also - more OC content pls... would that hardware Paul can't talk about be the 5800X3D? :D
Hoping this spikes another round of competition between GN, Jay and Paul :P
Imagine having to turn off everything in your house to run this lmao
I will confirm your statement on stepping away or sleeping on an issue being very true. I have had great success over the years using that methodology.
Please come back with more :D
love you paul, always have, always will...superb content as always, love this format.
Superb editing, sweet music etc. not a single complaint!....and you're a lucky bastard i only have a 1080ti and i'd love to get my hands on even a 3070ti would be nice lol
I had to watch. Last time I tried using SLI….*shiver*
What a rollercoaster! Awesome video Paul.
Good God, is that Palit card part of the Kardashian line? Holy gaudy!
Good content Paul. Was interested in knowing if you set the memory to above 40 GB in bios to see all 48 GB of those cards? Can't recall but I think it is MMIO Above 4G decoding.
5:25 I don't think a lot people realize this. Especially since another popular tech channel stated there's no performance loss. There is... and if the argument is that the losses are so minuscule then why even buy a 3090 or 3090ti over a 3080.
