Sapphire Radeon HD 7850 Non-OC edition.

I'm wondering what I should OC this to with stock fans... note that it is NOT the OC edition of the card.

Definitely maintain a safe clock, nothing that will cause my card to go over like 70 or so under load(or whatever temp is potentially damaging to the GPU).

Here's the link, in case anyone is wondering:

If it's of any relevance, I'll be using a i5 2500k OC'd to 4.2 GHz, and 8gb ddr3 @ 1866. Will be using it to record and play BF3, Tribes: Ascend, and War of the Roses in the future.

Thanks in advance.

  1. We don't know your particular chip, they all have different OC limits. You will have to try yourself, do 10 MHz increments until you are happy or it becomes unstable, then back down 10 MHz.
  2. How will I know if it's unstable, though? Doesn't stability depend on the application?
  3. You should be able to get it to 900 no problem. Just bump it up by ten and play BF3 for 10 mins. You'll know its unstable when there is artifacts, screen glitches, etc. Just don't go crazy and set something like 1000 Mhz to start.
  4. gpus won't have problems below 90C so you don't have to worry too much about the temps unless it hits 90+.

    All 7850 should have no problem at 1ghz but you should be able to push it higher. Some people have reported to have clocked 7850s to 1200mhz so its an overclocking beast.

    Just clock it to 1 ghz then slowly increase by 25mhz until it crashes in something like 3dmark11, then you know the max and just stay maybe 50mhz below that.
  5. Yeah, I don't have money for BF3, so I'll definitely be using 3DMark11, only demanding game I'll be playing is Tribes: Ascend, and that's because it's free. Will literally have nothing for games after I buy this.
