Hi all,

I am new to overclocking and I understand the risks involved. But I want to overclock my Intel Core 2 Quad to a stable 3.0 Ghz

From the BIOS settings, do I need to increase any voltage for my RAM or vcore for my CPU?

Please tell me what increments I need to change to or if I don't need to change it at all. Please lend a helping hand

can you select 400 for the fsb/cpu frequency? what cpu cooler do you have on the cpu?

what i would do,
set fsb/cpu to 400
set pcie to 101
set dram voltage to 1.55v
(been a while on lga775 but i want to say 1.2v on NB)
cpu vtt lowest setting since it is 45nm cpu, if you encounter problems go one maybe two steps higher.
cpu voltage, i would start with 1.25v
leave dram setting on 1066.

Yup I could change the CPU frequency range from 200-800. Are you sure that's the correct safe settings for a 775 socket?


My aftermarket cooler is this one

I have spent a long time overclocking my Q9400 CPU and from what I have found if you want to get a stable 3.2GHz overclock set the FSB to 400, voltage to 2.3 and CPU ratio to 8.0. Do not alter any other settings and you should be able to run this setup on a stock heat sink/cooling unit at around 40 degrees Celsius.

set what voltage to 2.3? if you mean cpu voltage you have lost your mind, that will kill a cpu in no time.

I recently fried a q9550 system I had running at 4250 (500 * 8.5). I tried to push it a little higher (I didn't even raise the Vcore) and that was it, never booted again. I'm still not sure if its the motherboard that's dead (the VRM's didn't have any heatsinks [thanks, gigabyte]) or the CPU. I was running around 1.4625V Vcore as well, which is outta spec, but not by much. In some ways I liked my LGA775 system better than my Sandybridge-E, which runs hotter than the devil's sauna.
