i have the same problem with my msi a88x-g45 gaming
cant find the TOLUD settings in Bios

sorry for the bump but same issue

Msi z270-a pro mobo
8gb ddr4
pentium g4620
4* 8gb rx480
1* 8gb rx580
win 7 x64

no tolud setting in bios, there is a 4g cryptocurrency setting that describes itself as allowing you to run several gpu's however with this on the system there is no video out

virtual memory set to 16gb, mines fine with 4 cards but adding the 5th gives error 21

any help would be appreciated

Windows 7 can be very difficult when it comes to going over 4 GPUs. Some people have had success with 5-6, but it's often hit and miss, especially when the drivers for these more recent cards don't support the old 6x GPU mod for Windows.

If you're not a Linux user, I would recommend using Windows 10, or at least Windows 8.1.

On Win 7 you can use six GPU with no problem ( with 6gpu_mod) On Win 10 you can use 8 GPU ( in my case).

windows 10 had the same issue, the solution did involve 10 though 7 modded would've worked

disabled 4 g mod system boots with 5 cards
install and patch drivers
reboot and enable 4gmod
system boots fine

so it appears for some reason windows wont enable the gpu at all if the drivers aren't patched while 4g mod is on resulting in a black screen
