Tried a lot, but am not able to find where the gap is. Basically I am able to boot up at 4 Ghz but not able to get into windows. I must say here that the heatsinks from Amarbir - Swiftech -have made a difference to the stability of the vcore.
I am trying to figur eout where the gap is as of now. I have reduced the HT and NB speeds significantly for 3.9. Do you think I need to go back up on that.
Temps are pretty ok with the computer idling at 37-38. Have not tried load temps at that level as it was not very stable.
I thing that I have understood is that the mobo makes a bg difference to the OC that you can achieve. I may think of going ddr3 and the new asus or gigabyte ddr3 board, but a top end one, as I believe that am3 would give me a good upgrade path even after 2-3 years.
Anyone have any good info on ddr3 boards, or nice OC DDR2 bords please do share.
