Hi!

Has anyone tried this board? http://www.gigabyte.com/Motherboard/GA-890FXA-UD7-rev-20#ov (http://www.gigabyte.com/Motherboard/GA-890FXA-UD7-rev-20#ov)

Got one lying around, gonna try and mount some GPU's  8)

I haven't tried it, but after looking at the specifications and images, I should say that it'd work out pretty good.

Just don't forget to use USB risers with it.

I have the 990FXA version of that board.  I recently bought it used on ebay with a cpu and cooler included.  I just recently got it (sorta) working with W7 and 6 cards via risers.  I used the W7 registry hack.  I had 4 x 480s and 2 x 470s consuming about 1010 watts, using a 1200 watt PSU.  It ran fine for about 10 hours and then crashed.  Problem after problem ensued. I'm sure if I got to aggressive with undervolting, or if the 1010W of 1200W is just not enough margin.  I'm keeping life simple for now, too much down time.  I rolled back to just the 4 x 480s.  They pull about 730 watts (ETH).

I'll be curious to hear your experience.  I'm a bit disheartened at the moment...  ???

I just started to test it, but still waiting for the cards, so atm only one Rx 480 directly on the mobo, working ok.
Im gonna probably make a 4 GPU rig, without risers, i got this Case that supports XL-ATX mobos and has plenty of room for 4 cards, so i probably can't be very usefull to ya :)

Pennywis3, did you made the 4 GPU rig based on this mobo?

Raja_MBZ, why USB risers? Regular risers (poweres) won't do?

Hi!

Only have 3x RX480 running on this board, directly attached, no riser.
I didn't attach the 4th card becase they are too close to each other.
Its very stable, no crashes or weird things going on, probably because no risers are involved  ;D

Hi Pennywis3,

Thanks!

Your cards would love more space thanks to risers - and three more brothers in the house! ;)
