Yes.
First I had it at 4.375Ghz w/ 4.375Ghz Cache. 1.3 Vcore, 1.4 cache voltage, 2.0 input voltage, 125 strap and BCLK. 3Ghz Ram 1.35 RAM voltage. Max temp about 68 degrees celcius. It ran good for about a week, and then I started getting q code 95 and sometimes 96.
I then dropped it to 4.25Ghz w/ 4.25Ghz cache 1.22 Vcore, 1.3 cache voltage, 1.87 input voltage, same strap BCLK and RAM. Max temp 60 degrees celcius.
With both OC's I had Level 9 load line calibartion and extrem power phase control for CPU and RAM.
