Lost power my GTX1080Ti with i9-7900X pc?

Hy there this is my first post here.So there may be things that are not enough.
Recently I built a pc of i9-7900X and GTX1080Ti 2WAY-SLI.
That PC shows me high performance at 3DMARK benchmark.
But that alone will result in considerably lower performance in real games.
It is also evident from the fact that utilization of gpu is rather low.
Of course I reinstalled the GPU driver and OS, but it did not change.
What kind of cause can be considered?

Please help me...

Do you have the HB SLI bridge? I would try both cards by themselves, if there 's no problems then it's SLI being crap. I would of also expected a higher firestrike. I had 30K+ in 2014.

 

Hello,
Of course I tried several hb-sli bridges.But it does not seem to change..
I can get IN Fire Strike

Make sure the game in question supports SLi to begin with. If it doesn't, then try running it with 1 card disabled.

Also, if the game does support SLi / is known for having good SLi support, maybe try some things like making sure the game is in Fullscreen mode, or turning off V-Sync.

 

Your Combined score seems low, this is what i got with my i7-6800K @ 4.5Ghz :

No cpu throttling ?

 

What games in particular are you having issues with?

 

Thanks guys.

Of course, I know that there are sli-compatible games and non-compatible games, but even games like gta 5 seems to be 20-30% utilization per gpu.
On the HWiNFO 64 it seems that thermal throttling is not happening.
In the 3dmark, it seems that there is not much difference in Combined Score compared with pc of the same composition.
It seems that there is not much difference in Combined Score compared with pc of the same composition. The highest value is 7,999.
There is probably something between i9-7900x and some models gtx 1080ti.

 

Try running your benchmark at a higher resolution, this way, puts better utilization across the gpu's, and less favor to the cpu.

you gpu's are calling for much higher settings, crank it up some, higher settings and resolution = more favor to the gpu.

Also use nvidia inspector, and try using the catzilla sli bits, under sli, put them all under autoselect, found out this gives very small increase in my final score in firestrike ultra.

Also, Always try to use nvidia inspector, AKA = Nvidia's Best Friend, for your sli setup and games and also AA, most of the time, it pays off, you won't regret it, it is a must program to have.

 

What resolution and refresh rate are you gaming at? GTA 5 really hits my cards hard at max settings and 3440x1440 resolution @100Hz.

If you're playing at low resolutions and 60Hz then the GPU's aren't going to be doing a lot.

 

I'm running 2560×1080 resolution @144Hz

Looking at other i9 and gtx 1080 ti sli, it seems that Combined Score is lower than Broadwell E .

The two Nvidia control panel settings that can make or break performance (excluding V-Sync) are power management and max pre-rendered frames.

Try at least Adaptive under power management (default is Optimal Power which may not ramp up the graphics card's frequency high enough for it's workload) and max pre-rendered frames set to 1 (Set this to 1 globally unless you are running a CPU intensive application. This causes the GPU to wait until the CPU has created the specified number of frames before it renders them, which can allow for stable delivery while the CPU is near-utilized).

Seeing as you have a powerful processor, lowering the max pre-rendered frames setting might help.

 

Thanks Mda400
pre-rendered frames can not be used in sli, only the power option is set to maximum performance.
The case seems to be incompatible with nvidia's 384.xx driver in some x299 environments.
Also, nvidia knows about it and seems to take measures in collaboration with motherboard makers in the future.

Maximum pre-rendered frames can be altered with SLI, they say it isn't recommend below the default of 3 as it might starve the GPU's but that could be dependant on how fast the CPU is.
There will always be an additional frame to prepare with SLI so a setting of 1 will mean 2.

Games these days are providing less and less confidence that multi-gpu will even provide a benefit. It's best to get the fastest card you can for your budget, then see if you really need a second.

 

Try updating your mobo BIOS, could be a conflict right there.

there is an sli bug on x299 platform ,
will have to wait for driver patch and/or possibly bios update

 

Yeah, apparently you need 382.xx driver, all 384.xx+ have this bug.

 

Thank you everyone.
When Nvidia 385.12 driver was applied, performance improvement of more than 10% was seen.

 

I would leave sli and crossfire alone and get the biggest and baddest single video card available and grin all the time. :>)
