Not volt modded yet, I plan on taking it to 1.4 or 1.5.. or 1.45... It ran these clocks with the stock cooler, although around 60c idle, 78~ load.
However, now it runs 40~ idle and 60 max load with CoolViva Pro on a decently warm day. Hopefully, I can take it to at least 700/1000 with some more volt mod.. not sure if I'm going to bother with pencil mod.
I bought an XFX "Xtreme" I guess. it was the cheapest 7900gs at the time, open box.
