ATI Hd 7950/7970 bios mod thread - Page 66

Can some BIOS clock states not be changed?

7950 here, modded bios with VBE7 tool. I'd like to keep my memory clocks at 1675mhz across all states so I don't have to deal with the flickering madness that bizarrely still exists after all these years when changing clock states.

In VBE7, however, it won't let me change the clocks on either of the first two states (under the "Performance" section). Whenever I try, the values get automatically reset to 300/150mhz (#1) and 510/1250mhz (#2). I'm able to change state #3 and #0 (the last/bottom state), however.

Without having to resort to Afterburner or some third party software running constantly, how can I change the default clock state memory speed of 150mhz to 1675mhz?

Ah, bugger -- so that means hex editing the right bits in the right spots?

Why doesn't it just let us change it like the other values?

The person who made the editor didn't think of it or know what to look for at the time of creating the editor, then he kind of just disappeared.

hello guys!!!
a few days ago i got a msi twin frotz 7950 oc

as im pretty experienced in oc ing i managed to customize my bios to my desired tdp and flash it also i have set the clock limits

now the problem is my card gets unstable when i go over oder near 1.2vgpu, that problem existed befor i was flashing the new bios
in fact i flashed the new bios because i though i would hit tdp limits again


did some1 expirience the same problems? the clocks i use are 1150 /1600 whouse are pretty stable but as soon as i up the voltage the card starts producing artifacts......

i hope some1 can jelp me because without the extra voltage over 1.2vgpu i cant get the gpu clock further and i really need as much power as i can get as i am running a 120hz display in bf3


i also ask myself whats up with the vrm signal? was that a way to up the voltage on locked cards? or should i maybe read more about it?

cheers^c


btw. my card gets 75-80°C in bf3, i already changed the tim of the twinfrozr which gave me about -20°C
post #656 of 1287
i now flashed the voltage viao bios and now it s stable to run 1.25vgpu, but the thing is i cant clock any further
it gets unstable at the same clocks than befor and i got a pretty huge vdroop

I wouldn't bother to clock higher then if I were you.
Not worth the extra heat and power consumption...

You'd be much better of by just grabbing a used 7950 and run CF.

i dont have the psu for an other 7950, and as it is a newely bought used computer i have to squeeze all the power out of it that i can because i want to play bf3 with 120hz
and the most reviewers got way more than 1150mhz

cheers
post #659 of 1287
To play BF3 with 120Hz, you'll have to reduce settings. For my 1440p 120Hz monitor, I have to use the Medium preset to get a consistent 120+ FPS. I normally run 1100/1600 but I can overclock to as high as 1300/1700, however I do watercool my 7950, so temps are never a problem.

Im looking to under-volt my power-color hd 7990 to make it run cooler while mining but I use Ubuntu for mining not windows. Can anybody guide me where to look to accomplish this?? If i under-volt my gpus would the watts consumption will go down as well??
Thanks in advance for any kind of help
Nico
