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.

  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?

That's fantastic thanks so much  Grin

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.exe

Just 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.

with this new cgminer.exe  at first it said my 7970 failed to start, but once in cgminer i enabled it and it started hashing
my 7970 is getting 384mh/sec  925mhz .9V
my 5870 is getting 349mh/sec 850mhz
338watts at wall

with diablo miner im getting 880mh/sec from same cards same speeds
but 388watts at wall

I just noticed my 7970 is showing A:0 R:0 HW:53  doesnt look like its accepting any shares??   Using diablominer now.

Thanks. I guess it's still horribly broken then.

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...

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...
