I have 5970's, anyone else seen or fixed this problem?
just doesn't adjust the voltage from stock
I have the conf file correct unless placement matters, put in the same area as auto fan, gpu clock, etc. all those work
I have reference cards, Windows 7 Home 64-bit and Radeon 12.6 with no extra SDK just the built-in
CMINER 2.6.4
OK I realize it can undervolt but was not overvolting that's why I switched to Sapphire Trixx to set the overclocks but i have to manually go in and keep typing memory clocks to get it down to under 300 if i try to set a voltage to 1.1v it defaults to 1.05, won't let me overvolt

do other programs like trixx or afterburner let you set the voltage?

What OS/driver/SDK/CGMiner version? Does it work if you remove the line from your config and use "--gpu-vddc 1.00" command option?

sorry, edited original post newest CGMiner 2.6.4 and "gpu-vddc" : "1.100",is the line okay im able to set the voltage, but the positions for the settings are not lining up with the cards at least according to GPU-Z and one time i started it, showed 2 cores as sick but i restart with the same settings and none are sick what is maximum voltage it can set vddc? i accidentally put 1.6 but luckily doesn't look like i killed my card

Overvolting isn't a good idea, typically. It's a good way to burnout your cores, or overheat your VRMs... However, minimum voltages are 0.95. Stock is 1.05. A stock 5870 is what, 1.163? You try like 1.150 or 1.200 or so, but again a word of caution - those put a lot of extra heat on those VRMs, and running at high voltages for 24/7 is not a good idea.

Have you tried changing the voltage from within cgminer? press "g" then "c" then "v".

no that defeats my purpose of being able to let it run itself unless i could add this stuff to the bat script

Hi,
Can you help me why my XFX 6950 does not undervolt using cgminer?
I tried g, c, v and typed in 1 or 1.000 but it still reverts to 1.10 V (default).
Btw, my card is flashed to 6970 bios
Thanks.

it will let you undervolt but not overvolt? what size PS do you have? got enough power for multiple cards? ran into this problem with my 6 x 5830 setup. I need more COWBELL! Sorry that just came to me.

Use the cgminer.conf file to set voltages it will let you undervolt but not overvolt? what size PS do you have? got enough power for multiple cards? ran into this problem with my 6 x 5830 setup. I need more COWBELL! Sorry that just came to me.
right. 1200 watts ese plenty 'o' cowebell

Use the cgminer.conf file to set voltages Sorry for the very late response, i was busy with work. Is it enough that i put it on my arguments of my cgminer.exe like this one: cgminer.exe -o http://pit.deepbit.net:8332 -u username -p PASSWORD -o http://api2.bitcoin.cz:8332 -u USERNAME -p PASSWORD -I 8 --vectors 2 --worksize 128 --gpu-memclock 675 --gpu-engine 800 --gpu-vddc 1.0 --kernel diablo --auto-fan --auto-gpu as you can see i put it --gpu-vddc 1.0 and I can still see 1.1 inside the cgminer console.
