furmark 1.15.1 won't use both GPUs in SLI
« on: April 08, 2015, 12:38:57 AM »
Furmark 1.15.1 won't use both my GPU's. Only GPU 2 is stressed and heats up. GPU 1 won't even budge. SLI is enabled in the Nvidia control panel > 3d settings > configure sli, surround, physx. SLI indicator is enabled from the 3d settings dropdown at the top of the control panel. i've tried using forced alternate rendering 1 and 2. I've tried renaming the furmark.exe to etqw.exe and SeriousSam.exe. I tried setting physx processing to CPU only instead of on a GPU. I tried running furmark as admin. I've tried running in full screen as well as windowed. Nothing works. I don't know what to do.

SLI works in OCCT just fine in windowed and full screen mode. Both GPUs are stressed and heat up evenly (they have a furry donut in their 3d testing tab. seems to use more power than furmark).

Intel Core i7-5960x @ 4.75GHz
32GB DDR4-3000 RAM
2x NVidia GTX 980 in SLI
Seasonic X-1250 1250 watt 80PLUS GOLD power supply
Chilled liquid cooling
Windows 8.1 pro, fully patched.
Nvidia driver 347.88.

Heres a log file and some pictures of the problem.
