Can't get multiple 7970's to their proper hash rate. [BOUNTY: 2 BTC] *SOLVED*

[dextryn]

Hey everyone.  I've recently run into some problems with my new setup I have.  Just to clarify, I have 4 7970's on another board and similar power supplies that work just fine.

My problem is that I can only get the 1st GPU to a hash rate of +/- 630 or so (which is lower than my other 7970s anyway)  and the other 3 kick it around ~250.

I've tried cgminer, diablo miner with Afterburner and nothing seems to work right.

Here's a pic of what I have:


When I run diablominer with Afterburner, after burner shows that the 3 other cards are running at 100% but they're still only at about ~250 as well.  Is there something I can do to help fix this?  Any ideas?

My motherboard is an MSI 890FXA-GD70

Also,  here is a picture of my afterburner monitor running as well.  You can see the first 3 GPU's jumping up and down.

I did some Googling, and I came across this stackExchange post that seemed similar

Seems that it's some combination of driver/sdk bugs. Booting linuxcoin from a thumb drive solved everything.

It might be worth a shot.

Only thing I can see is to cut out that second ",256" line in your worksize config.

What driver/sdk?

I remember my windows installation getting a little buggy now that I think of it.  I'll try reinstalling and seeing how that goes.

Hey, additional bounty (1 BTC) for whoever can help me with the best config for my cards (cgminer or whatever is best)

Install 12.3. And also try disabling ULPS if that doesnt work.

See this thread.

AzN1337c0d3r, 12.3 worked.  Send me your address for your 2 BTC!

Dont worry about bounty, consider it a gift to get your mining operation started
