Haven't seen anyone here with a voltage of less than 1.175.
How are you supposed to check in gpu-z? Just check the default voltage?
Well now you have. :p I have two, 1.1125v cards, and one 1.05v card.

Right click the title bar, Read ASIC quality. Mine shows 81.2% my default voltage is 1112.

Well, I think I've gotten the current cgminer git tree to support 79xx cards, but I have no one to test them. I certainly am not expecting any kind of magic performance out of the box. Anyone not afraid to try a git build care to give it a go? At this stage I'd at least like it to actually work rather than produce garbage which the current stable release does.

ck: I only have the 7970's on windows, and I have yet to compile your source. any chance on a beta windoz binary for me to test? Jim

Yeah, a compiled windows would be nice to test.

I'll try and find access and time to get a windows binary tomorrow.

That's fantastic thanks so much I committed a little more 79x0 specific code and built a windows binary. Again, no idea if it works, nor if it performs, but here is a windows build: http://ck.kolivas.org/apps/cgminer/temp/cgminer.exeJust drop it into a 2.1.2 directory, replacing the existing exe.

Got waterblocks for my 7970's on the way. I will post power usage with the cards under water too.

Sorry if this has been asked before, but at what temperatures are your cards running and how are you keeping them cool? Are you running them in a case? And if so, what case are you using?

Read carefully, that's a 5870 *and* a 7970... 880Mh is awful. 7970 is ~550Mh/s stock 5870 is ~380Mh/s stock so that's > 5% slower than what they should be doing...

with diablo miner im getting 880mh/sec from same cards same speeds but 388watts at wall I think that's a new record! Sorry if that wasnt clear, but my MSI 7970 runs way to hot to overclock it, even undervolted at stock speeds it sits at 79C my 5870 sits at 67C (though I had to replace thermal paste to achieve this). Unless there is some way to get my 5870 to use SDK and my 7970 to run on SDK 2.6 at the same time, my 5870 isnt running at optimal speed. Currently im pulling 968mh/sec 415 watts total. 6550@650mhz 5870@885mhz and 7970@925mhz You either got a bad card or some seriously bad case airflow there... 0. SI TAHITI XT (:0.0) engine clock 1170MHz, memory clock 1070MHz, core voltage 1.17VDC, performance level 2, utilization 99% fan speed 43% (2408 RPM) (default) temperature 72 C Powertune 10%

I just got my 7970 in today to replace my 2x GTX570 SLI setup. I'm playing with DiabloMiner for the first time (back in the day I used to always use Phoenix + CGMiner), and getting ~660 MH/s with 1125MHz core, however I'm having trouble downclocking my GDDR5 VRAM.
Any changes I make to the RAM don't stick (as reported by MSI Afterburner and GPU-Z), I've tried using TriXX and Afterburner to lower the ram speed, but it just sits there at 1375.
I have noticed that when I try to set exactly 1000 it actually works, and that's where I have it sitting currently.
I'd like to get it down to where I used to mine with my 58x0's (300 MHz, or 302 MHz depending on the card)
Thanks for any ideas!
