Any word on the x370?

I bought MSI x370 and successfully detected four GPUs but can't get the 5th to light up.

Curious if there is something I can do in the BIOS to get it to work or if this board might only do four and that's that.

Thanks.

MSI X370 will do 6 Nvidia GPUs, but it is difficult depending on your version of Windows 10 (build version). My OEM Win10 disks were build 1507 (I think). Lots of errors, restarts, was driving me nuts. And that is after I installed the AMD newest chipset drivers. What's more frustrating, is that Windows Update just crashes and fails over and over with this build version - just doesn't work with Ryzen.

Download Microsoft's "Media Creation Tool," download to ISO and make a USB boot stick (search for "Rufus bootable .ISO"), do not use the Microsoft product, just download the .iso image and use Rufus to make your Windows boot USB device. This will take a long while to download and run through updates. Then reinstall Windows10 using the USB stick/key only this time it will be build 1511. Start the build with one Nvidia card in the main slot. When you get to build 1511 (and before you install lots of software), make sure the one card is recognized and that you can mine. You need to then launch DDU and remove all drivers and shut down, not restart. When shut down, plug in all your other cards. Reboot. If Windows doesn't install the drivers, do so manually under Device Driver.

If you errors on startup, hit F11 to get to the Boot order menu and click on wherever you just installed the new version of Windows.

Beware the Microsoft Update Assistant (Blue icon) that comes with build 1511. Takes forever and it *may* update you to the 16xx build, and if you run it again, it *may* update you to 170x build. But you'll probably tear your hair out first.

Go to "PC Settings" > System > About: to see what build you have. If you have build 1507 or lower, that might explain all your problems. Update to at least 1511.

Disable Hi-Def audio in Bios. Disable Serial/Parallel I/O.

I think, more than anything else people mention, when it comes to Ryzen and 5/6 GPUs, it is a Windows issue.

ROmi,

Which x370 motherboard do you have exactly and what BIOS version did you get it to finally work with?

Thanks!

Sorry, to be clear: it IS running 6 GPUs and works very well. Not 4, not 5, but 6.

Romi,
Thats awesome information, thank you sir! I also have the MSI X370 Gaming Pro. I tried with BIOS E7A33AMS.430 and the new E7A33AMS.440. The new BIOS has the option for cryptominig however, it doesnt seem to affect anything except it no longer displays POST and you cant seem to get back into the BIOS without clearing CMOS.

Anyway, can you please explain how you are installing the drivers exactly. I have followed your instructions and I can get Windows to recognize the 6th finally after running DDU. I then tried to install via the nvidia package (v385.28) in normal (not safe) mode. It seemed to install but when I rebooted windows puked and entered a reboot loop and tried to repair itself. Any ideas?

BTW, the slot that sends windows into the repair boot loop is the very bottom PCIe 4x slot.

Thanks!
