Hi, my first rig was with msi z170a gaming m5. I enabled 4g encoding and changed integrated graphics configuration from PEG to IGD with bios vers 1.D0 .
This allows me to run 8+ gpu no problem. I think it can get up as many as 9 with pcie splitter or nvme to pcie adapter.
I just got a msi z170a gaming m7 and I expect it to do the same thing.
I am running 1.L bios and I reset everything to defautl.
Then I did the same thing as my m5, changed PEG to IGD and also enable 4g encoding. After doing this, the system wont get me to the windows screen and if I reverse IGD back to PEG and only leave 4g encoding on, the system wont boot to windows either.
After resetting bios, I can boot into windows without any problem
need help on this
I also tried 2 different bios. One is latest version and 1.H is the onther I tried.
I think the problem is with 4g decoding. Everytime I turn it on, I can't boot into windows. I did some research on this and find that many people with this issue which is after enabling 4g decoding, the system shows a balcklit screen and wont boot into windows. I can confirm this happens with 2 different bio versions.
my windows is installed on UEFI and I also tried enabling UEFI in bios and also tried UEFI + legacy in bios and the issue persists.
I can boot into windows just by disabling 4g decoding and I can boot with no problem whatsoever.
FYI my msi z170a gaming m5 is a plug and play.
All I did was flash bios to 1.D, enabled 4g decoding and change PEG and IGD, and it works like a charm. It can run up to 9gpus without any problem first try, I have no idea what is going on with m7
