Max GPU on this motherboard

[phaddie]

Hey guys,

 I have a ASUS P8-Z68-v PRO

 https://www.aASUS P8-Z68-v PROsus.com/Motherboards/P8Z68V_PRO/#specifications

I currently have 2 X r9 290 on it with a third coming tomorrow.  Will I be able to add a 4th or 5th card to this board?

 I have been unable to determine this from the specs.  It looks like it has plenty of pci slots, I jus lack the knowledge to determine how many I can use for my GPU.

  Thank you in advance

  Phad.

I have pretty much the same motherboard as you - I have an ASUS P8Z68-v LX

I currently have 2 R9 280x cards running on it. I am using risers for those, connected to the PCIe x16 slots. I also have another two of the same cards connected to the x1 slots with powered risers. I CANNOT get them to work though! I have tried everything I can find online - swapping cards/risers, changing motherboard BIOS settings and even installing jumper cables into the x1 slots. Nothing seems to get the other two cards to work though. There is power going to them; both green lights and both fans are spinning on ALL cards, just windows and CGminer are only detecting two cards.

If you find out how to get it running please let me know! I am desperate to get all four cards running on my system!

As of right now I have 3 290's running on my board.  All using powered risers in the 16x slots.  I hope to add at least 1 more.  I will let you know when I get it (hopefully couple of weeks)

Ahhh, I just googled your Mobo and you have an extra x16 compared to mine.

And yeah, please let me know if you find out how to get extra cards running from the x1 slots!

Cheers!
