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? MY Fire Strike 1.1 RESULTS 16248 IN Timespy 28 977 IN Fire Strike It's good but in game is not...:wanker: MY PC SPEC MoBo:ASUS X299-DELUXE CPU:Intel i9-7900X CPU COOLER:Noctua NH-D15 RAM:Corsair Dominator DDR4-2400 16GB*4=64GB PSU:Cooler master V1200 platinum intel p600 128gb***12288;OS disk intel DC3520***12288;GAME AND documents disk Windows 10PRO 64bit NVIDIA DRIVER 384.76 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 Graphics score 50 025 Physics score 23 666 Combined score 7 588 Regards, panda
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 : http://www.3dmark.com/fs/13117943 No cpu throttling ?
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 GTA5 Maximum out setting[etc longshadow] GPU utilization is 50% now Frames Per Second (Higher is better) Min, Max, Avg Pass 0, 40.381760, 83.015762, 70.219795 Pass 1, 39.936005, 83.534622, 63.733700 Pass 2, 52.812195, 137.125412, 75.059082 Pass 3, 57.636314, 140.949890, 106.277557 Pass 4, 22.570040, 137.691666, 78.687401 Fire Strike Ultra 1.1 Graphics Score 12 909 Physics Score 23 737 Combined Score 6 319 Looking at other i9 and gtx 1080 ti sli, it seems that Combined Score is lower than Broadwell E . Regards, panda
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. Regards, panda
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.
https://forums.geforce.com/default/topic/1019423/x299-sli-i9-compatibility-issues-fix-eta-/ there is an sli bug on x299 platform , will have to wait for driver patch and/or possibly bios update
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. :>)
