Help needed with MSI X370 Gaming Pro and MSI 1080

[Isidzukuri]

Hello,

i'm having isues with installing 3rd (and 4th of course) card in X370 Gaming pro MB.

Rig specs:
Msi x370 gaming pro (not a carbon one)
a-series apu 9500
4 gb ddr 4
128gb ssd
windows 10 x64
msi gaming x 1080

SO when i'm installing first and second card, everything works ok. But when i try to add 3rd, system interrupts show 50-70% of cpu time, and in some period of time system reboots.

Risers are checked, cards also work good.

What should i check?
ANy thoughts please.
Thanks.

what's your PSU ? brand ?
if risers are okay did you check the bios for gen 1 PCI E ?

2 Chieftecs: APS-850CB for 2 cards and system, GDP-650C for 2 cards

There is no gen1...3 switch in the bios, only "Above 4G..." setting.

Hey man!

So you have enabled 4g decoding?

What bios version do you have for the motherboard?

Yes, after i installed the system and added one card.

Currently i use latest bios firmware, 7A33v45.
Also tried previous one, 7A33v44, but it was the same.
Haven't tryed earlier versions, because they lack 4g decoding.

Try and follow the steps in this guide and use the integrated gpu, maybe u can get some ideas and get it to work.
Even tho not for x370 the guide but might be some useful information .

Hmm have u tried disabling usb 3.1 in bios

If shit hit the fans install Simple mining os  on a 8/16 gb stick and see if it works  with diffrent os.

Good luck.

Thanks everybody, i managed to run it.

It started working after i plugged in cards in the following order: 2,3,5,6.

If i was trying to start from slot 1, it wasn't working on the slot 3.

Best regards)
