Im overclocking the q8400 at the moment ive reached 3.2 with no issues with a 1.300v. The issue ive got is my min mem multi is 2.0x which with a 400fsb sits the mem at 800, which is the mem type ive got, now i can goto 3.4 with mem slightly overclocked @ 851 i think, and a 0.1v increase as booting with no increase had issues and the cpu was @ 1.316 i think. When booting the system seemed slugish, my theory is as with a previous cpu is that the mem dosnt like overclocking even though it is decentish corsair with heat spreaders. Is there any other way i can get a higher cpu overclock without raising the mem.
Temps with prime 95 full load small ffts ran with many passes
overclock @ 3.20 800mem ratio 8x
there is also a difference between core 1 and the rest, but i have reaplied the thermal paste and reseated twice and no change. But i do pass prime95 no issues.
The nb and fsb v are set to default at the moment, the only reason i wanted to go higher is that the temps im getting from the cpu are well within safe temps and was hoping for an easy 3.5 overclock, i could take the easy option and buy some 1066 mem but im building another pc in 4 or 5 months with an i7 and ddr3 so pointless getting the 1066.
also im only using a freezer master pro 7 rev 2 heatsink and fan i feel its coping well,
