I just bought my self a brand new 7950 it's the msi twin frozr model.

I think the clocks are just 800mhz on the one I got and I want to bump it up to around 1100mhz if possible.

So whats the best program to use? and how much voltage should I put in?
 
Use MSI afterburner, theres a thread on it somewhere by LTmatt in this section of the forum. Perosnally i got my Gigabyte 7950 to 1100 mhz on stock volts but this varys from card to card.
 
I use Trixx if its just for Overclocking then Trixx is fine. But if you want the other feature Afterburner offer use that.

Start by increasing the core, aim about 1000 for for testing use Heaven 3.0. No crash? higher core 1050 if you crash higher voltage +10 till you get to your target speed of 1100.

The Memory you should be ok putting it right to 1575.

For an example my 1100/1500 needs 1.131v yours wont be the same but it gives you idea.
Stock voltage on my card is 1.031v

Dont increase the Voltage passed 1.3v for your 1100 you shouldn't need more than 1.2v

I hit 1150/1500 on my MSI 7950 Boost Edition without changing any voltages

What your stock voltage though?
Edit
Just seen you have boost edition, this explains why lol your card is voltage higher then most stock cards because your card right from the get go is aimed at 1000 core.

mmm not 100% sure as I cant check at the moment because im at work but I think it was 1.125 I could be wrong lol

Ok thanks that's very helpful and should save me some time tomorrow.

Whats the safe voltage limit on these cards?

That explains why then :) Boost edition come pre clocked to 1000 so therefor a higher voltage.
Where a non boot edition where the clock is 800 or 900 is much lower voltage stock.
 
on stock i can get 1200/1425 - and as said already just up 1 clock at a time and find your limii :) can be time consuming but its better safe than sorry
 
I know its a shame that my wf on stock memory voltage [1.5] can only reach 1300...i can get it to 1500 memory with 1.65 memory voltage, but id rather leave the memory voltage at defualt.

Its a shame because my msi 7950 did 1800 on the memory at stock :|

Its strange how my 7950 WF stock was 1.250v and i could hit 1150/1500 but when i tryed to lower it, it was a real pain. I could only get 1.231v stable

Yeah the latest bios comes with 1.25 volts stock which is plenty for any overclock you wish imo. Mine also came with that bios that your using and I lowered the volts to about 1.43 for 1150 on the core. Whats the max temps your getting with those volts and oc?

And yes 24/7 max safe voltage is 1.3 but i wouldnt really take it above 1.25 if it was my card. I dont know about memory voltage i see people ramping it up to 1.65 though.

Max is 1.3v you shouldnt go anywhere close to 1.2v tbh

Explain? And why shouldn't u go anywhere near 1.2v? Loads of people do including me I think this is more opinion than fact tbh.
I run my card @ 1150/1450 24/7 @1.225 1250/1580 max mine is a 59.99% ASIC card.

People do to over the 1.3v limit but I really wouldn't recommend it(generally with wc loops)i would try to stay around 1.25v or below aslong as temps are good (generally the vrm temps create instability before the core temp in my experience.

I've not upped the volts on my memory and generally don't see much point in ocing the memory too much as he speed and bandwidth is plenty even when the core is overclocked u hardly see a difference in benchmarks let alone in a gaming environment.
