AMD - How To Overclock The Official Way Using Afterburner + Step By Step Overclocking Guide + Comple

I don't know, you used winflash and not atiflash. You should have followed my bios flashing guide here.

Follow that guide and try using this bios if you have a HIS 7950 Ice-Q. If http://www.sendspace.com/file/5mv49f

If you have a different card maybe stick with the bios you've already got.

Try aiming for 1100/1250 using 1.2v vcore. If thats stable then try 1100/1400. If thats ok then move up to 1100/1500. Once you've got that fully game stable for several hours then worry about pushing the core further.

Oh ok, I'll try your flashing guide when I get home tonight. Do I need to flash back to the stock BIOS before doing so or is it ok to go ahead with the one I've got? I do have a HIS 7950 Ice-Q, so I'll use that BIOS you posted.

After that I'll go with your advice about memory speed. Thanks :)

Nah just flash over the bios you're currently using. Its all explained in the guide. :)
 
I believe that while 1.2v seems feasible, is not for 24/7 use while on air.

The GPU is creating a lot of heat, and the fans kick in at full speed. Which is ok if you live on your own, in a detached house like me, but for the "others" going to be a serious issue.

Personally scaled back to 1100\1500 @ 1.150v and the fans never goes more than 50%-(50C), making it comfortable to live with. (same noise levels like my old GTX570).

After all 125mhz more, aren't worth the extra noise, heat and shortening lifespan of the GPU.
Rather get a second card for CF if I want more perfomance. (which I will do end of the month).

Yes i find 1100/1500 a good balance of noise vs performance. Any faster and you really need to ramp the fan up to keep the gpu's cool.

ok thanks. Sorry didn't get chance to read the guide yet.

Also 1 last thing before I do it, my ASIC is 53.4%, does that make a difference to which BIOS I should use?

The bios you want is 925/1250 (this one http://www.sendspace.com/file/5mv49f) and will apply the required amount of voltage depending on your cards asic. In your case it will be 1.175v which is plenty for 925 core. Stock bios voltage is 1.250v, so you can can see how much overkill that is. I can reach 1100/1500 on 1.175v. Your mileage may vary. :)

Excellent guide, thanks very much.

Got my HIS Ice-Q 7950 crossfire setup running 1100/1500 @ 1.175v. I could go higher, managed to get it stable at 1200/1600 @ 1.200v but really no point pushing it further as it's needing exponential voltage increases (with the accompanying noise increases) in return for marginal gains.

Good stuff. Sounds like you have a nice clocking card there. :)

I've flashed the BIOS using your guide and I've set the card to 1100 core with 1.2v and mem @ 1250. Heaven v4 ran the benchmark but crashed shortly after finishing the bench. Far Cry 3 crashes withing minuates. So I bumped the vcore to 1.25v, FC3 crashed after 10-15 mins.

What do you think? Looks like I need to lower the vcore speed? My card can't even handle 1100? :(

What are the temps getting to? Do you have the power line at +30%? You can always try dialing back the clock to 1050. Probably best to work up in smaller steps.

Did the follow the guide in the OP? What were you last stable clocks?

Temp is max 71c I have the power line at +20% should I be on 30?

I did follow the guide and I reached 1100/1675 @ 1.225v/1.600v, but I was only testing in benchmarks. As soon as I tested in game I was getting crashes.

I think I'll start again from stock and go up slowly while testing in games as well as benchmarks.

Yes i always found i needed 1-2 extra notches of voltage to be stable in games vs benchmarks. Leave the memory at stock 1250 first to rule that out as an issue. Only when you're 99% sure the core is stable at 1100 or below try fiddling with the memory. Use 30% just to rule it out as an issue.

People that are going to use and benefit from this guide should not be putting that much voltage through their card imo.

Why not? :o
 
Dabbling with overclocking and well I'm a bit clueless and unsure about adjusting voltage.

My 7950 is at 1031mV by default, does that translate to 1.031v? Whats a safe increment to increase voltage in mV and what would you recommend as an upper limit for the inexperienced. Cheers.

If you want to play it safe try 1.100mv-1.150mv.

Just a quick update.

I reverted to stock clocks and slowly upping the core speed, currently on 1025 and stable, mem stock. Anyway, just had a quick question about Afterburner. When I boot up my PC and afterburner runs, the fans are on like 50% because my fan profile hasn't been applied. The OC is applied but not the fans, I have to either click "User change" twice or go into the fan settings and simply click ok. Any idea why this is?

Try ticking force fan speed update. ;)
