My configuration is Asrock X470 Master SLI, Ryzen 5850X and 2 x 1080Ti.
Till today all worked well with SLI and 2 GPUs - on default UEFI settings.
Today I upgraded CPU from Ryzen 3600 to 5850X and problems arised. After installing it suddenly computer started to detect only 1 gpu - the one in primary slot.
After some Googleing I played with PCI-E lanes settings and result is as follows:
-x4x4x4x4 - 2GPU - still no SLI
What does it mean? Does MOBO not support more lanes or is it CPUs fault?
I am woried because I felt unpleasent smell when testing CPU with Prime95 - maybe something inside CPU or MOBO got rosted ? Or is it normal? I am afraid it can greatly affect performance.
1200W PSU about 6 moths old Corsair
no iGPU - but each GPU works separately in x16. And both with x4x4x4x4
HDD Samsung 970EVO 512
Windows 11 - updated
Newest drivers from nVidia
