Mobo confirmed to work 2/dual 5970's

March 06, 2011, 01:54:48 PM

I was all excited to plug in a second 5970 into my system, only to find that there is apparently a bug of some sort that keeps it from booting (can't even get to the bios screen and no video signal when both are plugged in). This is an ASUS M4A89GTD/Pro USB3. Don't not get this mobo if you plan on running dual 5970's.

So, now that I have to get another mobo (and desiring not to be a beta tester for the mobo manufacturers), I'd like to find one that is *confirmed* (by someone actually running dual 5970s) to work. I need an AMD socket am3 mobo.

It's not the mobo. Your power supply is deficient. Buy an 800 Watt Antec or 800 Watt Corsair. And before you tell me, "Well, I have a 1000 Watt XXXX Brand" bear in mind that the ratings on power supplies are pure fiction. Here's a 1000 Watt Corsair delivered to your local Walmart for under $230. http://www.walmart.com/catalog/allReviews.do?product_id=12457257

I do in fact have an Antec 1200W power supply...here's the model:

Based on the following thread, it seems I'm not the only one experiencing trouble with this mobo:

I have opened an issue with ASUS. But the question remains...I'd like to hear from people with a dual 5970 setup with a socket am3 mobo, which specific model are they using?
