13.1 AMD Drivers, MSI-AB unlocks

CGMiner, Diablo, Intensity 10, other hash settings default

All Cards are at Stock Voltages

690-700Mh/s, 74C
XFX 7970 (FX-797A-TDFC Rev5, brown box)
OC: 1160mhz GPU Core, 1300mhz Memory
Default: 1000/1475

*Originally got 2. Despite identical stickers on the outer retail box, when opened inside one box was black, one box was brown.
*The brown box had stock bios v33, 925/1375.
*The black box had bios v32, 1000/1475.
*The black box one had awful fan noises at max speeds.
*When in crossfire mode, it seemed to me whichever card was on top overheated and had to be shut down. I have an Antec 300 case, with 2 front 120mm intake fans, 120mm side intake, and 120mm exhaust top and rear.
*Planning to return the noisy fan black box version for a refund.
*I did try swapping bios around between the two cards. No problems running on either. Kept the 1000/1475 bios for the brown box.
*Cooling is otherwise fine if the 7970 is on the bottom or by itself with open access to air.
*When I tested stacking the 5870 with 7970, and the 7970 is on top with no open space access, it seemed to cap out at 95C at default clock.

395-400 MH/s, 87C
XFX 5870
OC: 925mhz GPU Core, 300mhz Memory
Default: 850mhz GPU Core, 1200mhz Memory


I'd really like to get a second 7970, preferably with XFX. I'm not sure if the problem is with XFX Quality Control/Cooling Design, or you just need watercooling in 7970 crossfire setups.

How can you get the core to go up so high. I thought catalyst control center limits it to 1125. At least his is with my CUII card.

QG

I'm running a DirectCU 7970 at 1200 core for around 710MH.  78C or so.

Gateway: I'm kind of jealous of those temps. I can sustain 660 or so, but that's running 82-84C. Cannot figure out how to get memclock less than 150 MHz under core without causing very odd display problems.

Very nice.. what drivers and sdk are you using?

What power supply do you have?

cheers!

Specs/mhs:

Correct, it does not improve hashrate or hurt it. It solely brings overall card power down fairly well.

I don't think from what I have read that lowering the memory will get the hash rate higher, I think it just lowers power usage correct?  Currently not paying for power tho

you can get the memclock lower than that if you use msi afterburner 2.3.0 with the two added ati files in the directory.  The final step is to never follow the reboot it asks for as that locks out the memclock control for some reason. See if that works for you, it should save dome more power and heat.

Screen shot if any..

Am I missing something?

Also your settings for your card should be running stable and not have to baby sit it please.
