February 25, 20188 yr I have a problem and after 24 hours of research, I am always at the same point so I seek your help.Okay, let's be clear.My GPU score in 3D11, Fire Strike, ... is really not good while on the Z270, it is correct.For the 3D11 benchmark latest version 1.0.132.0Z270 APEX + 7700K 5GHz + 1080Ti 2050/1500 + 16GB 3600C15 -> P28425 (43708 - 13664 - 14199)X299 DARK + 7980XE 4.5GHz + 1080Ti 2050/1500 + 32GB 4000C19 -> P33211 (41229 - 22291 - 18948)I made several installation (win10 1703 on both motherboards), same Nvidia drivers, same benchmark, I have tested with win10 1709...I installed the APEX X299 and bad GPU score too ...For me it does not come from a hardware component, nor the nvidia drivers, nor the benchmark, ... If you have an idea... thanks !
February 25, 20188 yr I think it's pretty clear that your gpu is powerful enough to be slightly singlethreaded limited for the gpu test
February 25, 20188 yr Crew compare 7700K @ 4.5 and see if it matches more then... or clock the 7980XE to 5ghz
February 25, 20188 yr Author Yes, and always good score GPU with 7700K @4.5GHz (uncore 3000)... GPU score 43140
May 10, 20197 yr Who ran on x299 platfrom old video cards? I tried to run two 8800 ultra in SLi Win7 x64, but without success, I tried different drivers on which I was guaranteed to work on the 1151 platform, but on the 2066 in the driver settings, the SLI option is missing. When I insert two GTX580, then with the new 4xx drivers, if it works, when I roll back to 285, then if it disappears. Strange problem.
May 10, 20197 yr I think this is due to the drivers being older than X299 platform... and thus not allowing to run SLI. Each platform must be white-listed in the driver, otherwise it won't show option to enable SLI. Try this patch https://www.techpowerup.com/forums/threads/sli-with-different-cards.158907/
