Try 960 core (1.05v), about 400mh/s. Temp was almost 80C, decreased to 68-71C (fan @ 80%) after a dose of Prolima Tech PK-1. Room temp is about 34-35C during the day, definitely much better than it used to be with 5 cards.

I used to run the cards at 775 core (0.85v) at 330mh/s when BTC price was less than $15.

depending on your card, you can go up to 950 mhz without any voltage adjustment. just use cgminer (which has built-in overclocking without limitations). please note that above 850 mhz, the card may be unstable for anything other than 2D/mining, so don't run any games, or use aero mode.

Use CGMiner.  You can set any engine clock speed and have it adjust based on target temps etc...  A must if not in front of the miner 24/7.

Hi everyone,

I own a 5850 card which is limited to 775Mhz Engine Clock. I am overclocking using gpuminer. The card is a Gigabyte.
I am reading through other topics that people are clocking these more than 900Mhz.
Any idea how to go beyond the 775Mhz point?
