Just done some benches on my iceq x2 and it never went above 1.172 vddc. I adjusted it in His Turbo, is it possible you don't need to do flash the bios on these cards to get the vddc lower? or is furmark and valley just not pushing it enough.

I have the gpuz logs from both tests, going to try bf3 and log that to see if it get the saem results.

Then increase the vddc in his turbo and see if it pushes up to 1.250 while benching.
 
Just put a nice shiny pair of these cards in, and thanks to all the help from LtMatt in the opening posts, the cards are already running @ 1100/1300 with the stock volts from the custom bios.

Will play with overclocking properly later

cheers.

Have a pint on me
 
Hey LtMatt. Awesome work on this thread!

Been watching this thread for a while and am very interested in getting a copy of your own 1125/1500 @ 1.2V bios.

I think my card is very similar to yours so would like to give it a try. Cheers.

What's the best overclocking software to use with these? Getting a bit tired of constant afterburner beta's.

Afterburner is the best, beta 15 is the latest. You can use iTurbo and Trixxx instead if you prefer.

That's just my max overclock. Not really a specific bios. Nonetheless i created a bios for you like that using the editor.

1125/1500 @1.2V - Increased TDP limit so this overclock should work on 0% power tune. (you might need to increase it a bit not sure)

Help! Just booted up this morning and my text is all corrupt. I'm using stock levels, as shown in the picture. Not sure if it's connected to reflashing etc. Should I reinstall graphics drivers?

EDIT: a cold reboot did the trick :/

Trying out the increased TDP bios from the first page now. All looks ok so far in Valley with 1100/1500 @ 1.175v/1.600v and 0% power tune.

Going to see how much further I can go before the cards want more volts.

That's my experience with the Iceq x2 as well - it's voltage seems to stay put when set using trixx, and monitored using GPUZ whilst gaming. I've also yet to see any boost spikes so have a feeling they changed something with this revision.
 
Didn't manage to get much further without voltage increases.

With clocks set to 1125/1550 @ 1.175v/1.600v I ran through Valley several times without any crashes, lockups or artifacting however I couldn't shake the feeling that a crash was just around the corner. Sure enough, increasing the core to 1150 caused a crash within about 10 seconds of starting the benchmark.

In the interests of research I managed to push the clocks to 1175/1700 @ 1.25v/1.625v but at those levels the cards started artifacting once the temperatures got above 65C (which happens fairly quickly with those sort of voltages). I'm not comfortable pushing the voltages further and I don't think it'd be worthwhile anyway as I suspect my cards have reached their limits.

I think I'll settle for a respectable 1050/1500 @ 1.175v/1.600v for everyday gaming, for the sake of balancing performance with heat & noise.

All in all, the increased TDP bios seems to work well, results are pretty much the same as what I was getting before but obviously without the need to fiddle with power tuning.

ALL HIS 7950 ICE-Q users should flash this bios. Forget about the other ones, this is the best!!

As Tommy has already stated with this bios you can overclock and use ULPS. No throttling. You can leave power limit at 0% and still run a decent overclock like 1100/1500. @1.175v and your card will not throttle. However eventually you will need to increase the power limit. So if you go much higher than that use it.

Purely for my own understanding and curiosity, what have you changed in order to 'disregard' the power limit? Also, what's the fan profile like for these bios?
Thanks
