I'm having a bizarre issue with one of my XFX 480s. It's running so much cooler than my other 480s that the fan does not have to spin up much past 40% to keep it under 70c in a 24c room. This is causing the memory (or the mem controller?) to overheat, making the mem controller throttle to 80% and i lose about 20% of my hashrate.
All of my other 480s run much hotter, the fan spins at about 60-70% top keep it under 75c, and the memory controller does not throttle at all.
I'm not sure if I hit the holy grail, as the chip refuses to heat up, or I'm screwed cause then the memory overheats.
I figured the easy solution would be too just set a low target temp so the fans ran more aggressively, but even when I set the target temp to 60-65c in WattTool, the fans maintain about 50% speed while the chip is ~70c.
anyone have any insight?
