MSI 970a-g46 works good with 1x to 16x extenders
4 5850 sapphire about 480 watts with undervolted sempron

Anyone know how to get 1x working MSI 990XA-GD55 I've tried the pin shorting trick and added a molex adapter.

Asrock 970 Extreme3 I can only get one of the 1x slots working with extender so just 3 slots with this one

Sounds like you may have a bad motherboard. I've had no problems getting both 1x slots working with that motherboard.

I have 7 rigs running 4 x 7970 with the Asrock 970 Extreme3. It's a great motherboard and inexpensive. You can pick it up for $79.9 at newegg.com. You will need two 1x to 16x risers and a custom shelf to hold the two cards on the risers.

I've had a lot of issues with Gigabyte and MSI motherboards and have found Asrock to be better and cheaper.

WHAT WORKS
Motherboard Brand: ECS
Motherboard Model & PCIe Slots: A885GM-A2, four 16x, two 1x
Power Supply Brand & Model: One Antec 750, one Antec 500, one Ultra 600
Number & Model GPUs: four 5870s, two XFX, one Sapphire, one ATI
Extender Cables w/Molex Power?: two 16->16, two 1->16, no molex power

Note: the 750 is powering two 5870s and the MB and HDD, the 500 and 600 each have one 5870 of their own. I'll be putting them on a new Antex 620 in the near future. Using customer external setup, with a normal box fan blowing on it. The 500 and 600s use a paperclip power on switch.

looks interesting, you don't see that many boards with 7 pci-e and especially not in that price bracket

I have the same board, and it does work with 4 GPUs. I am actually running 5 on one right now. (same CPU too)

BUT, the last two I have bought have a bunk PCIe x16 slot! Both of the last two I bought had a bad PCIE4 slot, that is the middle x16 slot. I have a third coming from NewEgg right now... I hope it works, because I like this board otherwise!

I've had a couple of the asrock 970 boards come a little flaky. I just bought 20 of them so I had extras when I was building out my rigs.

They also sell these boards at amazon. If you have prime, you can same of the shipping charges.

http://www.amazon.com/ASRock-MB-970EX4-970-CrossFireX-Motherboard/dp/B0058HUQJ0

If you only need 4 PCIe slots on a board, you could also check this one out as it is $30 cheaper.

Has anyone used a Gigabyte GA-970A-UD3 (not the -D3 version, but -UD3)? Considering getting a few of those.

I didn't use them, but like I said earlier in this topic, if you want to boot with an USB key, this brand of motherboard can really be a pain in the ass.

Older post, but I will echo the words. I have that model of mobo packaged up for return right now because it wont boot off of my USB key (not sure if its the UD3 or D3...)

How do you determine what's working when you have conflicting reports on some boards?
P.S. Try Googling "ga h61 d2h-b3". That board does not compute.
