So I had bought a e6550 a long time ago and thru poor attempts at overclocking thought I killed my board. Original board was a P5n32sli e or something like that. Then I thought I killed 2 evga 32 sli boards. turns out I killed the OCZ ram. I figured that out when I purchased a P5N-D to try and rebuild my gaming rig(twin 8800 gts 320's) which was pretty sweet back in 2007.
either Way I found out whent he borad would not boot and I found out what the beep codes were that the ram was toast. I now have 4gb of OCZ value at stock 800mhz. BUT.....
I have got my P5N-D up to 1850fsb, which puts my e6550 at 3.23Ghz! Fastest I ever have. I used your voltages from the very first post of this thread. With vdroop the cores run at 1.35volts. Ran Prime for 9hrs last night no errors. Played Farcry, GTA4, Wow, and NWN2 and had no errors. Just wanted to say thanks for the post and I'm enjoying my 900 free Mhz. I tried 1900 fsb with no more voltage change and I had a prime error immediatly so I quickly restarted and went back to 1850.
Oh and temps at Max load never went over 42*C
My build is P5N-D @ 1850 fsb
