MSI afterburner OC help

post #1 of 3
Thread Starter 
Alright brand spanking new to this new 7950 from powercolor, has the stock cooler. I see core voltage (mV) my stock is 1069. I want to confirm that this means 1.069 volts.
Do you guys use power limit at all do you find it does anything or just use extra power when idle?

So as of right now I haven't punished my system with running Heaven benchmark but I have spent couple hours in BF3 an all seems to be fine. With stock voltage and 20% on the power limit I seem to be able to run 1000Mhz and 1500 on the ram all day long. What's average would you guys say for peak OC for stock voltage?

What are you guys averaging for fps in bf3?

I don't know if I'm reading your question correctly, but here's what I think you're asking for. There are lots of opinions on the safe voltage on a card, but I myself prefer to stay within 0.1 volts of the original voltage. Call me paranoid, but I rarely go over that (Especially with stock cooling), but if your card can stay cool after 0.1 volts over, I'd go a bit further until a max of 0.15/0.2 volts over, also beware that by increasing the voltage you are potentially shortening the life of the card. If you don't change your voltage when overclocking, you won't be able to get a very large stable overclock, and because of that, you won't get a big, if any at all performance increase. In my opinion, I don't see why you'd overclock a 7950 with stock voltage. Overclock it as high as you want, so long as it remains stable and stays below 80* C. Also, when you actually overclock, use heaven on highest settings for that card.

Hope this helps! smile.gif

I use to use Trixx for my overclock on my Sapphire. Stock voltage for me is 1.250. I now use the CCC and nothing else. I leave voltage alone and run the 20% power option, been running at 1100/1500 since day 1.
