7990 Tahiti setup / voltage?

[massnerder]

did you try core 1050?  that's the only difference in my settings and i am getting 1.43mhs, but my temps are higher too, 81/73

You're getting 1.43 from this one card?
The temps are okay, mine are usually around 80-84 on both GPU's (2x 7950s).

Yes.  To be fair, this one card is technically 2x 7970 on a single bus, but yes I get over 1.4mhash with my 7990.

My 7950s run at / below 70c, they do 640khash per card and are volted down to 1100... can't remember what clock speeds I am using

I didn't volt mine down. How did you do that?
Which models do you use? Could you provide cgminer configs for comparison?

Use msi afterburner beta version to undervolt, i believe all the details are posted earlier in this thread

I see only settings for the 7990.

7950 I use core 1100 mem 1650 voltage 1100 threadconc 24000 i 20 w 256

7950 I use core 1100 mem 1650 voltage 1100 threadconc 24000 i 20 w 256

For the sapphire card?

that's right. i have 4 of them all using those settings, all running at 640khs and 70c

Mine is running at 640khs and 64c, thank you but they weren't needed.
