Im very new to this overclocking with GPU's, I just OC'd my sapphire 5850 to 900mhz/1100mhz with 1.18 volts. My maxtemps using furmark (The creepy, furry, with red veins thingy that just sits there) test is aroung 70 - 80 C. Is this safe for my card and will my card survive 24/7 using these settings? Thanks and more Power!
Seems pretty safe as the voltage isn't too high. I wouldn't have it running at 80C 24/7, but a couple hours a day shouldn't do too much. I know Asus allows you to run their 5850 at 1.3 volts while still being under warranty, so one would assume that 1.3 volts isn't anything that would break cards easily as long as you have sufficient cooling.
i set it up manually using the MSI afterburner,when it is idling in mid 50's C, i let the fan run 30%"very silent BTW", when its over 60 C, the fan fires up at 50% fanspeed,and when 70C,it fires up to 70% fanspeed and so on.
(I'm not totally sure on this) I think i scratched the gold PCI-E connector on the card, when I removed it from my motherboard, I took it out to clean my PC and when I put the card back in I got no display at all, but the fan worked ok.
Lesson learnt, Be careful when removing graphics cards.
When it was working I had it OC'd to 820 core and 4200 mem. No extra voltage, it was nice and cool (roughly 65C when gaming) about 31 idle : )
I got mine very stable right now. 900 / 1220 on 1.2. I keep fan on fixed using trixx at 75% which isnt toooooooooooo loud. 80c is the highest temp i've seen so far. Seems to be a good O.C. range for this card although 950 / 1250 is do able , I don't like to put full stress on my components.
