Can a motherboard cause GPUs to artifact.

I had 2 HIs 7950s, rans perfectly. (I wish I never sold them now).

I have had 2 MSI 280x GE (sent back as they were artifacting/ HW errors mining).

I have another 2 MSI 280x GE that are doing the same.

I have flashed BIOS.

I have changed PSU with the 2nd set.

I just cant believe I have had 4 faulty 280s.
 
Ive had this problem before with a faulty motherboard, causing artifacts on boot up screen and constant crashing. This was on a brand new build
I replaced the motherboard and all was fine.
You will have to eliminate all possibilties to find the culprit, motherboard is usually last
 
Might possibly be a broken trace or an issue with the PCI-E slot. Have you tried to alternate them see if it's the same in each? It's not likely but possible. Run a single card at a time. Get some compressed air and blow it down the slots, people underestimate the importance of good contact.

BF4 artifacts like mad. Other games just crash or I cant see any artifacts. Sould artifacts show in every game. (sleeping dogs just crashes to desktop when I load into the game. Arma 3 looks fine, Hitman looks fine. I have only played them for a couple of minutes each.)

Heaven/valley I get the odd it of flickering or a block of pixels flashing.

I have tried each card.

Tonight (wife permitting lol)

I am going to sort this again each card in each slot.
 
Not really, it's the card misinterpreting data so it doesn't have to be consistent, far from it. I'd definitely try a single GPU at a time and clean out the slots. Only takes a little dry join and everything goes Pete Tong. It could also be that you've got yet another faulty GPU, but I'd like to think you're not that unlucky :D.

PSU could also be at fault, but cross that road when you come to it. Normally you'll see a few hard resets when underload or OCP kicking in.
 
Ok I have spent the last 4 hours playing BF4 and Crysis 3. Now i get artifacts, sometimes seems to be a blosk in the same place all the time.

I will have to upload some of the pictures. But it looks like they are going back. :(

And looks like they are out of stock.
 
yh, anything that'll overlay your temps, framerates. I used to use the stats part of AB till it started throwing fits. Not even installed it now.

If you haven't yet, test with the 13.12 whql drivers.

Other than that it does look like maybe a pci-e lane has gone down on ya. RMA time if you can't test (shame you moved them 7950s so quick) :(
 
This does not look right on one of the cards.

Temps were ok.
 
Just to let you know, that my gfx card looks exactly the same ^

I think it's the cleaning fluid they use, makes it look like a badly made card :p
 
Motherboard _can_ cause artifacts but not very common - sometimes they need a firmware update to properly support a newer card and if your OCing the CPU its possible the PCI-e bus is being raised depending on board and settings - awhile back some boards would have a "GPU Boost" bios option that would tweak the clock speeds and other low level stuff on the PCI-e bus and also raise the GPU core clock - not very common now though as it caused more problems than anything else (infact not aware of any 115x/2011 board that has that options).

Back in the day an unstable north bridge could cause artifacts on the GPU but not sure if the same can happen with an unstable IMC - might be worth temporarily removing any RAM overclock.
