I've got gigabyte GA-890FXA-UD5 motherboard, which has 2 PCI X1 and 4 PCI X16 connectors,
I've got 2 ASUS 7970 MATRIX, 2 Sapphire R9 280X Vapor-X and 1 Powercolor 7970 V3 (together 5) GPUs.

No matter what I do, there's always 1/5 GPUs that gives code 43 error when I look in the device manager. First I thought that there was something wrong with one of the specified,
but now I see that every card works if there are 1-4 connected and one of them doesn't if there are all connected.

Can this be resolved or do I have to buy another motherboard?

Thanks for help

any news ? i got the same issue

I have been trying to get 6 cards (or 5) to work on my rig.

6x 7970 on an asrock H61DEL which has 1x PCI 16x and 5x PCI 1x

So far I can get cards working in every slot, BUT only if 4 cards are plugged in at any given time.

If I plug in a 5th or a 6th card, device manager shows them with a little exclamation mark.

If I try to mine I get a BSOD

I have tried the following drivers with no luck
11.x (doesnt work with 7970)
12.4 (BSOD)
12.8 (exclamations in device mgr)

Anyone had ANY luck running such a combo?

Yeah I don't touch the CPU... I am having a hell of a time getting 5 cards working on this machine.... I have tried every possible combination.... I am going to burn a fattie and take a nap, this sucks.

Well the 890FXA-GD70 has been known to catch fire around the VRMs due to low power phases (4+1) versus 8+2 on higher-end boards. But that's only if you were overclocking and using 125w TDP CPUs. Wink

AHHHHH this makes total sense. so the last 16x slot would be disabled...

What about having to short pins using 1x to 16x risers?

Yes, I believe that too.

I believe the GD70 has a thing where you only end up getting to use 5 of the 6 slots, the last slot ends up being disabled.

Can someone please tell me if I have to short any pins on this board when using 1x risers?

when running 5 single core cards which slots do you use? which slot out of the 6 would you not use?

Any issues using 1x to 16x riser in the 16x slots?

Thanks

I am stuck....

How the hell can I do this with a 890FXA-GD70... has a total of 6 PCI-E slots...

with 3 cards on the board and 2 on risers....

Do I have to use certain slots if I am running 5 cards? Has anyone out there used 5 cards on one of these boards ?

can only use 5 of the 6 PCI-e slots, it turns off a 1x slot if PCI 1 and PCI 3 are populated.

#@%&! where the fuck was this answer when i needed it over a year ago! Cheesy

yeah sorry "guy" I was only referring to single GPU cards, and the added expense of buying those expensive cards! easier to plug in 4 dual cards than it is to actually get 8 cards on a single board. and ya gotta give props to anyone who takes the time to get a 8 card setup running, Win or *nix.

Use risers and its pretty easy Wink

yeah 8 gpu can be used at once but not many boards will ALLOW you to use 8 gpus. Got 890-gd70 and can only use 5 of the 6 PCI-e slots, it turns off a 1x slot if PCI 1 and PCI 3 are populated.

If you're going to go for 8, you're going to want 4x dual gpu cards.

Nice... this board has 6... curious if I could get 6 cards running on it .

x64 will do up to 8 gpu cores.
