HD 5870 is a heat monster, but loves the cold
For the last week I have been playing with the cascade on the cpu at -108c to -103c, and a 2hp single stage on the gpu running -55c load testing this card. I tried giving the card between 1.35v and 1.5v and it just wasn’t stable, couldn’t even clock the card to 1050mhz. At first I thought the card was a dud, but just in case had to try it on ln2. What I did find out is the card is a heat monster and needs at least -80c to clock above 1200mhz. At -130c MSi after burner maxed oute core at 1275mhz. I tried both MSIAfterburnerSetup142 and MSIAfterburnerSetup150Beta2. I have flashed the card to MSi bios 910 I think.
Can any one suggest a tool or bios to make the card clock past 1275core. This card has no cold bug so I have big plans for it
