Safe oc level for 6850

[AMA8o8]

I have a sapphire single fan 6850 and was wondering how much I can oc this thing without having to get an aftermarket cooler

There is no such thing as a safe OC level

(stock is 775/1000) --- 780/1020 still safe as long as fulload fumark under 75C also raise speed fan GPU 50-70%

Anything that doesn't need a voltage increase and stays within acceptable temperatures for the card.

Every card is different, just use the sliders in CCC to increase clock speeds until it becomes unstable, then back them down a bit. Keep an eye on temperatures, but so long as you aren't increasing the voltage, you should be safe.

I OC'd my single 6850 to 900/1200 on stock voltage an the temps never went above 72*C ever.

2x crossfire 6850 900/1150 on stock voltage temps max at 75-77*c but average around 70*c when under load.

As long as you don't mess with the voltages the clock speeds will not jepoardize the card provided the temps are reasonable.

Voltage increases are generally safe also if you know what you're doing. 99% of people who blow up their stuff were just too greedy to accept that their hardware won't be stable at X speed and X voltage like "that" forum guy, or like X review, even if it doesn't warrant any noticeable speed boost, just for the bragging rights. So they keep pushing and pushing and pushing and reach almost 20% over-voltage and still ain't stable and they go desperate cause that guy got 500 more 3DMARKS so they push it just a bit more then.... it smokes.

Hey man, Epeen length is a big deal
