Hi
Im trying to get my q6600 over 3.0ghz. Ive had this setup for about 2 years now and ive never been able to get more then 3.0ghz without bsod's and crashing, so im in need of help badly. i'll start with my setup

q6600 (Stepping b/ Revision GO) with corsair h50 water cooler
asus striker 2 nse 790i motherboard
Gtx 295 graphics card
2x2gb corsair dominator 1600mhz DDR3


Im up to 3.0ghz and all ive done is put fsb to 1333, ive never messed with other settings. Please someone help i want to get it to 3.6ghz if possible. Thanks :)

If memory serves me from when I used to have my trusty old Q6600, the key to OC'eing it is unlinking the memory from the FSB and don't overdo your voltages. If you don't unlink then your memory will cause the BSOD's way before you run into CPU issues. Also, you start getting diminishing returns on performance versus the need for massive cooling at around 3.4 - 3.6 so I'm not sure you how yours will do.

You'll have to change the memory multiplier, and maybe also change the PCI bus to 100MHz. It is generally recommended to put the memory multiplier as low as possible, get the speed of the CPU up to where you want it, then maybe fine tune the memory. You may or may not get a Q6600 to 3.6GHz.

At 3.6GHz the lowest setting of your motherboard would have your ram running at 800mhz. I don't know what the highest setting would be but it could be running the ram pretty fast.

There are plenty of overclocking guides on tom's as well as elsewhere on the net that will help you with that CPU. Also you can google "q6600 overclock" and find lots of people that have overclocked their CPU's and see what settings they used.

Im not great with all this overclocking stuff, i need someone to put up some settings to try if possible

Ive raised the cpu voltage in the overvoltage section to 1.425v and got the cpu up to 3.249ghz. Cpu temp is not going over 45c and cores around 60c. have i raised the right thing? Seems to be really stable

Well i thought it was stable, just got a bsod

1.425v should be enough to get to 4.0 try to back it down a lot.
1.30 has me stable @3.16 and 1.35 3.33 138xx 3.6 they are all different but you are using way to much juice.

As i said, im not great at all this overclocking and need someone to help with settings. There must be someone out there thats got the same setup as mine?

what are your memory settings?

mem is at stock settings 1600mhz timings are 9-9-9-24

anyone?? im about to give up on this, there must be someone with this board and cpu thats managed to get a good overclock

What i did for my Q6600 OC was as follows, with the following hardware:

Q6600 (Stepping b/ Revision GO)
ASUS P5Q Pro
2 x 2GB G.Skill DDR2 - 800

Set FSB to 400
Kept the RAM set to 400MHz (hence the DDR2-800)
Set Vcore to 1.39
Set the CPU/RAM ratio to 1:1 - Manual

Ran @ 3.6 GHz for a long time with not one Blue-Screen

I got my Q6600 up to 3.6 GHz in a GA-EP35-DS3P. Vcore was 1.42 volts. Load temps were 61 - 66 C, 24 hour Prime95 stable. All 4 of my Core2 systems are running at 1:1.

Unlink your memory settings. Run the memory at half speed. That will temporarily remove the memory from the equation and you can focus on the CPU. I'd do stopping points at 3.3 GHz and every 100 KHz after. At each step, stop and work on your memory settings.

Do not exceed 1.5 volts core voltage or 70 C load temps. Also do not exceed 1.65 volts on the RAM.

I thought that DDR2-800 RAM was rated between 1.8 - 2.1

As i recall mine was stock 1.9 and i bumped it to 2.0 so i could lower the timings to 4-4-4-12

It has been a while though
