What is a stable OC for 5770 without volate increase?

Hi guys.
I currently have a 5770 and wanting to OC as i dont plan on spending more money for a better graphics card.
Of course im not expecting it to be a HUGE improvement but even a lil' would help.

Here are my specs:

Intel i5-2500@ 3.7GHz
12GB DDR3 @ 1333Mhz
(GA) PH67-UD3-B3
Win Power 750Watts
Liquid Cooling
PowerCooler 5770 1GB GDDR5
Windows 7 Home Premium ( 64-bit )

I play games such as Crysis, Crysis 2
BFBC2 and BF3 (when it comes out).
Also FSX ( Flight Simulator X )
The new version of FSX is coming out 2012 hopefully by then i would of got a better GPU :)
I also play online games, but thats not to worry since my Specs obviously are capable of playing a vast majority.

Many thanks!

More about what stable 5770 volate increase
  1. ***Resolution:1600x900***
    Also sorry bout' title. I was meant to say *Voltage*
  2. Same as Cpu's, each Gpu will O/c differently, but I get 960/1300 on my Sapphire 5770, any higher on the memory and it dies
    res 1680x1050
    download CCC and try the autotune, just to see how much it will push you 'safely'
    Moto
  3. yeah 960 core here as well. Mem takes 1350 and then some I just stopped at 1350.
    With the AMD overclocking tool found here I did get 1000 core it wasn't really that stable.
    It really depended on the game, Crysis warhead yes ....War hammer rise of caos not at all

    regardless use the vista version it works.

    Then again maybe just do what moto said.
  4. Ok. Thanks :)
    Do you guys tend to see any FPS increase or something like that? :)
    If so, by (roughly) how much/many?
  5. Depends on the game, don't expect miracles but it's worth it maybe 2 or 3 frames or more depending on your resolution
