340MHs on a 5830.
Core 1030 / Mem 340 Stock volt, air cooled. Using Phakt kernel, Worksize 128 fastloop off
63C Shader Temp with PCIE slot base Frequency upped to 102mhz and an ambient room temp of 71F
Unstable after about 3 hours, so bumped down to 960 with the same memory and am getting a stable 288MHs.
NICE! What brand was that 5830?
Sapphire Xtreme 5830, purchased from newegg.com before I even knew about this bitcoin stuff.
It was unstable if the machine was used, so I bumped it back down, I was worried something might happen when I was away.
Don't want to come home to a smoking case.
