I've been struggling overclocking my Q6600 until I found a guide for it on the OCUK website. My system is:

- Arctic Cooling Freezer 7 Pro
- Abit IP35 Intel P35
- 4GB Corsair PC2-6400 CAS4
- NVIDIA 8800 GT
- OCZ 600W power
- Intel Q6600 GO
- Antec 900 case (fans on low)

Using the recommendations I changed:
FSB: 333
Multiplier: 9
CPU Core voltage: 1.405
RAM multiplier: 1:1.2 (to get DDR2 at 800MHZ)

The set up has just remained stable on prime95 for about 2 hours with no temperature change which I am delighted about.

Running at 3GHZ I therefore get the following temps, measured using Everest:

Idle:
CPU surface 37 °C
Core 0 33 °C
Core 1 33 °C
Core 2 27 °C
Core 3 32 °C

Load:
CPU surface 55 °C
Core 0 51 °C
Core 1 51 °C
Core 2 46 °C
Core 3 48 °C

The highest a core creeped upto was 54 but it quickly came down.

Is this an acceptable set-up? I haven't changed any other voltages or anything but it seems to be running stable :)

Very similar to mine after about 2 hours of prime. Have you already upped the vcore?
Click to expand...

I changed the cpu voltage to 1.405 if thats what you mean? I used the recommended amount for that overclock. I haven't tried lowering it yet.

What is your vcore?
 
1.275 in bios and 1.3 in windows. I kept it standard and after 2 hours of prime, nothing so i'm happy. I'm going to give it a week to bed in and then i'm going to push it as far as possible. Hopefully get 3.5 :)
 
This may sound stupid but does memory multiplier affect RAM speed? Mine is set to 1:1.2 and my ddr2 records as 399.6MHZ in cpu-z meaning my memory is running roughly at 800MHZ? I just wanted to make sure my Memory is running at its 800MHZ

I will try that. I'm gonna do 7 hour prime95 on 1.4v tomorrow for 7 hours and then I will continue lowering voltage after.

Other question as previously said, does the memory muliplier affect memory speed or will the cpu-z reading always be half? My memory multiplier is 1:1.2 in bios in order to counter the FBS to make RAM 800MHZ so the 400MHZ seen in cpu-z means im running at 800MHZ because its DDR2, if that makes sense. If someone could confirm :p
 
I'll put it another way, does Memory timing have to be 1:1, or is 1:1.2 just as good at getting 800MHZ when upping the FSB to 333?
 
No and Yes. 1.1.2 allows you to archive 800 Mhz ram frequency without having to run your fsb at 400.
 
oh I see, so 333 x9 with a memory multiplier of 1:1.2 gives a RAM speed of 800MHZ.... I see. My bios actually tells me
 
Ran prime95 for 7 and a half hours. Antec 900 all cases fans on low, silent as a mouse and the Core temps were: 52 52 47 48 after that time. Highest appeared to go was 55 degrees for a second every now and then. Not too bad at 3ghz
 
Ok an issue, despite running Prime95 for 7 and a half hours at 1.385V and it going fine I have noticed that the initial few screens after turning the PC on with the option to go into bios etc run very very slow and on a couple of occassions have actualled froze. Is this an indication of too low a Vcore??

Would this indicate that the next highest Vcore (1.405) which runs stable, is the most suitable for running the cpu?
 
I have the same CPU, cooler and board but the abit overclocking program says my CPU is running at 50 °C and thats before I even overclock it. It goes up to about 60 °C if I have been using it for gaming.

Any ideas?
 
I get 28-34 idle and 50-56 100% load.

You could run something like prime95 or OCCT to see the range of temperatures you get. Would be good to see what you get under 100% load on a stress test as when I game my CPU doesn't get to full load.

I'll give prime95 a try and see what I get. Just seems that everyone on here get really lower temps than I seem to be getting. The whole system is in an Antec case so it should be cooler than that.

Maybe theres something else I can do?
