Would I benefit from upgrading the BIOS? Never flashed BIOS on a GPU before... if someone could maybe explain the process or give me a link to directions i would appreciate it. I dont know if I need to update or not, but I thought I'd come here and ask since you guys seem to know an awful lot more than I do about this,

LOL i can't find this one - please tell me what's your stock clock and stock VDDC?

Stock clock is 900 ....... The date on the BIOS version if from January 31, 2012 if that helps at all.

VDDC: 0.801-0.803
MVDDC: 1.602
VDDC Current: 7.0A


Under Load--

VDDC: 0.918
MVDDC: 1.602
VDDC Current: 56.5A


I got these values from GPU-Z... I hope they help in determining this. I would really like to update the BIOS so the voltage will be unlocked. I really want to give this GPU a nice little OC.

I think this must be the old F2 bios. You can flash to new F2 bios version, however if you don't have issues with this one you don't need a new one. By the way can you check what is your asics quality in Gpu-Z? If your under load VDDC is so low it must be high asics quality and you have very nice 7950 which can be clocked very high on stock voltage. Most of gb 7950 wf3 owners are not so lucky(including me) because the newer revisions of this card usualy have lower asics quality.
However it can appear that your card is hardware voltage locked and if this is the case you won't be able to unlock the voltage via reflashing the bios. Just have it in mind.
by the way why do you think it is locked? May be you don't do something right. Which program do you use for overclocking?

I thought maybe I'd get better performance with the new BIOS or something. I do not see any ASICS numbers on GPU-Z - can u tell me where to find that? Yea, I do not kno0w why VDDC is so low.. is that the voltage going to the card? When I tried OCing with Overdirve I was able to bump the power settings up.. but I did not see any difference in VDDC numbers when running a benchmark. I have tried overclocking to 940mhz but my video card keeps blacking out when running benchmark under that setting. I am using Over Drive to OC. Should I use something else?

What are some good starter settings I can use to OC my 7950? All settings I've tried have seemed to fail after a few minutes, even though temps never even reach higher than 55C. I'm not sure what to set the Core Clock, Memory clock, or Power control settings to. Any help would be appreciated so I can finally see if I can get a decent OC out of this thing.

So you don' t need to reflash. CCC overdrive does not have an option for voltage control. For this you need for example Msi Afterburner. Just download it - it's free. When you start Afterburner go to settings and on the 1st page select unlock voltage. The program will ask you to reboot and after rebooting you will be able to control your voltage. Don't go to the max- 1.3 V. Try at first with max 1.15 -1.2 V. Also tell me when you start afterburner what is default voltage there. And remember - there is a power limit option(also present in Ccc overdrive) and when you are trying to overclock this option always must be set to +20.


For asics quality option - press right button of the mouse on the high left part of Gpu-Z. You will see it at the bottom of the menu.

When you start to oc do it step by step(do you remember this movie smile.gif ). First try without changing the voltage. Set only the core to 1000 mhz and test is it stable - for testing use Unigine Heaven or Valley, 3dmark and some actual game like far cry 3 or crysis 3. If you are stable you can increase a litle and if it is not - decrease. You can do the same only for the memory. When you find your stable settings for the core and ram seperately, you can test them both. If you don't like your clock on stock, just increase the voltage to 1.5V and try every step you did before with stock voltage. If you don't like the results again - go for 1.2 V. For me personaly 1.2 is the maximum i would use for 24/7 overclock so my advice is don't pass this.

I just bought a 7950 WF and it came with 1000mhz on the core and 1250 on the memory; the BIOS Version is 015.029.000.003 (BIOS Date 2012/12/18) and it seems to be voltage locked, the problem is that at 1.25v it doesn't go past 1070 mhz and I was wondering if my bios is bad for overclocking are there any alternatives? My asic is 57.9 is it supposed to be so bad that it can't get even to 1100?

ASIC on my card is 84.2%... is that bad or good? Default voltage on afterburner was 944.

What steps should I increment when raising the memory on the card? Also what kind of increments should I go with when raising the core clock as well?

Your asics quality is good for 24/7 high clocks on lesser voltage. i have a personal way to OC:
1st. try what can you achieve on stock voltage without touching the memory. Set up to 1000MHz and test for stability. If you're not stable decrease by 5MHz each time until you are stable. If you are stable at 1000MHz just go to 1050MHz and test. If you're not stable do the same decreasing by 5MHz steps until you are stable, if your card is stable at 1050MHz go up to 1100MHz. You do this until you find the max stable clock for stock voltage.
2nd. When you find your max clock on stock, set the voltage to 1.15V. and try everything again. When you find the max clock for 1.15V if you are pleased with it you can stop or if you are not pleased set the voltage yo 1.2V and do it again.

For the memory - go with 50Mhz steps and test everytime. If some artifacts or other issues appear go back with 25MHz.
When you find your max clocks for memory and core test them together. If it is stable - you're ok, if it is not decrease a little from the memory until you find stable clock.
I don't say it's the best way to OC but it's my way. smile.gif

I'm sorry to hear that. You have very low asics quality - almost like mine... smile.gif I have 58.4%. I think you can get better clocks but you are with FZ1 bios and your voltage is locked. You can reflash your bios with F43 bios version( your stock clock will become 900/1250) but do it under dos with atiflash. You can read about reflashing here. Be sure that you read everything and understand it before make a try to reflash. But i'm not sure that after reflashing you can get higher clocks. For example i can get 1100MHz on core with 1.2V. But you can get 1070 with 1.25V. But at least you can try and you'll have lesser power juicing your VGA.



And i'm sorry for my english - it's a little rusty. smile.gif

It worked with the F43 now the card is stable at 1100 with stock voltage, I wonder If I can push it further but msi and the CCC have the bars maxed out now

What is your stock voltage now? And are you sure that you are stable on stock? How do you test it? I'm asking because on stock which is 1.094 i can get only 980MHz.
