[SOLVED] 2080ti SLI rig

[misharialanjari]

Hey guys,

https://www.3dmark.com/fs/17807494

The above will show you my firestrike extreme score and my rig setup, the PSU is a 1200W Cooler Master Platinum.

My FPS when I play BO4 - Blackout mode is a lot worse than when I ran 1 2080ti.

I even tried just running a single GPU but I can't replicate the performance of when I just had 1 GPU on my system.

Any thoughts or feedback on this issue would be highly appreciated.

That Firestrike score is completely normal for those specs.

No developers want to put effort into supporting SLI because you're like less than 1% of their target audience. That type of performance is 100% normal for SLI.

Just look at how many titles lose FPS when you add a second 2080 Ti.

I had to learn the hard way GG :/ I might make a 2nd PC with the extra GPU without the water cooling.

Usually boost clocks go down when sli is enabled, if it's not supported by the game it's not uncommon to hurt frames

Agreed, the part that's not normal is the FPS drops in BO4 lol

I hear ya, and it seems the "Single GPU option" in the Control Panel doesn't seem to do the trick either.

Nope it knows the other one is there and gets scared lol

Lmfao, ur the 2nd person today who's made that same joke!

Guess you could sell one of them and get a 9900k? And a giant m2 ssd

Keep the water cooling! I sort of wish I had a second reference board 2080 ti + waterblock for my SFF ATX build

Hey,
1) Have you disabled SLI then tested?

2) Apparently there are different AFR modes. Have you tried them all such as AFR2?

3) Sometimes NVidia nHancer profiles work that are added by others. Download and try that (launch nHancer then click the tiny icon, find the game in list change settings and save).

Other?

*Looking at performance though I'd try to just disable SLI (can you do that for just that game?) as you add a little latency and the FPS on highest settings should be super high already... if you have 4K monitor I'd drop to 2560x1440 if the FPS isn't high enough (I know it would still be fairly high but some people like way over 100FPS).

I have disabled SLI, no effect, program settings in control panel to Single GPU mode no effect as well. I also tried AFR 1 and 2 but no effect. I will give nHancer a try.

Technically you are using NVLink with 2080Ti’s. In games that support Sli your scaling should be better than prior generations of gpu that do not use NVLink. I have only seen a couple of NVLink reviews but it does seem a small improvement in scaling. However if the game doesn’t support sli then all bets are off and as pointed out above performance can be worse than a single card.

If nHancer is the wrong tool it may be NVidia Inspector... anyway, I Google for it again and ended up with THIS which seems the latest option:
https://www.softpedia.com/get/System/System-Info/NVIDIA-Inspector.shtml

Extract and just copy to make a "Program Files" folder then make your own shortcut to the EXE. My path looks like THIS:
C:\Program Files\nvidiaProfileInspector

Then I just clicked on the main EXE inside and said "Pin to Start"

Then drop down to "Call of Duty Black Ops 4", select an SLI profile (for DX11?) save changes then try it.

Your problem when you have SLI disabled and still arent getting the same fps as when you completelty take the card out is because your card is still running in x8 instead of x16. 2 cards is a waste of money man, i have 2 2080ti and i dont use the 2nd one at all, Nvlink will only be worth it when devs put time into including it in their games, and or A SYNC/ explicit mGPU which pools the resources of both cards. Shadow of the tomb raider and Sniper Elite 4 both use A SYNC and you have butter smooth gameplay, sniper elite 4 is how mGPU should be, Its almost perfect. Its annoying when you have the best hardware money can buy, (especially when we work our asses off to buy these parts) and you cant use them as advertised and there are settings that still cant be maxed out on games. But at the same time, we should be happy we even have a 2080ti and as long as people keep bitching about it, they will do something to change it. I hope, Im losing hope, WTF GTX 1650!???!!!
