Help diagnosing whats causing my Rig to crash.

[JayyCee]

Alllrighty then not sure if this is in the right place but here goes.
I have been having some trouble connecting 3 RX580 cards to my rig, After running anywhere between 2 mins and 2 hours my rig freezes or crashes. Here is what i have done to try and diagnose whats happening.
I was running one card for months without an issue. Sometimes it happens when not mining at all.
Temps don't go higher than 60 degrees celcius. No mods to BIOS of the cards. using

My specs are as following.
Asus z9pe-wd8 motherboard W 2 xeon 2692 cpus not overclocked and watercooled.
64GB ECC ram.
Three rx580s. 2 in pci x16 and one in x8
Enermax platimax 1350w PSU

Here is what i have done to try and diagnose whats happening.
I have ran memtest with no errors, i have reinstalled windows twice, updated and removed drivers 3 times, once using DDU.
Mind with each card alone no problems. Mined with each combo of two cards and it only froze up once.
Using a power meter when mining with all three cards use 600-700 watts when undervolted or 800 stock.
Changed pci to gen 2 in BIOS and also pci latency to 96 and also 64 ( i read somewhere that doing that had helped with getting 6-7 cards to work)
Undervolted each card to -36 which seemed to work for about 4 hours but still crashed which makes me think its the PSU but its still only using 600w out of 1350w
Changed the rails around so each card is on its own rail, or shared rail on PSU.

I have tried everything i can damn think of and still at a loss to know what exactly is causing the problem. And was wondering if any one here has had this issue or knows whats wrong.

Give us a full system spec , including driver versions , windows version , what miner software are u using
Are u using powered risers ?
Can you check the widows error logs ( event viewer ) and post it here ?

Pretty detailed report. The quoted text seems like the key point. It suggests the problem was triggerred by the
installation of the 2 new GPUs. It could mean it's the number of GPUs or a specific GPU. Try removing
one or the other new GPUs to try to stabilize the system. You could also try swapping risers and slots.
There should be a pattern that leads you to the cause.

Shit sorry i posted the wrong draft... Windows 10, No powered risers as stated they are in the x16 slots directly on the mobo.
 
As for event viewer i cant post the whole event log however i recreated the problem and  shows a    41 kernal-power system.

Driver version 22.19.162.4

As for mining software it happens on any one i use but using prospector v 07 on Skunk Hash

I have done so, I moved them around switched to different slots. I am able to use the older one with either one of the new cards without it crashing;. And only once did it crash with JUST the two new ones.
