Overclocking Q6600

[matty-hodgson]

i run mine at 3.6 with 1.4v
seems like you've got a bad overclocking one

G0 or B3 stepping, do you know?

G0 stepping which is supposedly better for oc?

And Moogle, I think you are correct. At well over 1.3 I have the very worst VID possible.

Right, well after getting my system set up and everything, I think I am finally ready to give this a go.

One thing I wanted to check, if I Overclock the system and the overclock is unstable, will the system boot up and then crash suddenly, or will it not boot at all.

To reiterate, what was said above.

Memory divider: - 1:1
CIE: Off
Memory timings to: 5-5-5-15 (If I am setting the memory divider to 1:1 do I need to mess with this?)
FSB from 266 - 300

Reboot and prime95/IBT

Have used Prime95 before and it seemed to do the job, so have no problem using it again.

it might boot up then crash, or it might not even POST at all.. if it doesn't POST then a CMOS reset will do the trick.

it's best to set the timings to 5-5-5-15 and the divider to 1:1 until you feel you have overclocked the CPU enough, then you begin messing with the memory OC.

just taking it 1 step at a time makes troubleshooting much easier.

also.. the FSB can go much higher than 300.. 300 will only give you a 2.7GHz core clock.. for a 3.6GHz or something like that you'll be looking at a 400FSB.

Well I want to start with small overclock, nothing to drastic.

Then, when/ if I get it stable, ill check my temps, if I am happy there not to high, ill bump it up a bit more..as for a ram overclock..hmm dont know if I am going to bother with that.

If he is going for 3.6 then he doesnt need to OC the memory.
3.6 is spot on 1:1 for PC6400 RAM

VID - the volts that the CPU runs at at the standard (boxed) speed, with it set to auto. Am correct???
and if so, is 1.264V good for my Q6600 GO???

also CPU-z says revision GO, but stepping B???? I thought it was B3 OR GO, not both

and sorry for butting in

[matty-hodgson]

do you mean that like?
if it's the same as that, then it's a G0


EDIT: No problem

[Will404]

Yer, just like that minus the nice overclock

Thanks

Well, after a super hectic past 7 days of sitting on unopened boxes (not literally) of a Q6600, Gigabyte P35 mobo, 2 Gig of DDR2, Akasa 965 and a Western Dig 640AAKS, i finally got them installed into my P180 case.

I was playing around with it all for a few hours as i was also installing stuff, and increasing the clock frequencies a bit at a time between reboots.

So far, i'm at 9 x 355 (= 3195Mhz) still on stock voltage. I have everything set to manual, so i know it's not changing the voltage behind my back It also hasnt crashed yet, so i've higher to go before i start changing voltages.

One question though - the BIOS reports stock voltage as being 1.325 (approx, from memory), whereas CPU-Z reports it a) fluctuating and b) between 1.14ish and 1.18ish.
Which is right? I'm guessing CPU-Z, but why is the BIOS so different?

VDroop, under load the voltage decreases. If the first article is confusing read this thread

You usually have an option in the bios nowadays. On ASUS boards I remember it being Load Line Calibration and it might be something else on others. It usually reduces the VDroop, but you never see the exact same voltage as set in bios
The closest I have got is on my board where I put 1.2875v and I see 1.28v in CPU-Z which is quite nice.

I can go to 3.4 without a voltage alteration so you 'might' be able to go to that (depending on motherboard aswell).
3.2ghz though is more than enough grunt......and you havent go to worry about putting more power through it either

[sjbuck]

What sort of temps are you all getting? I'm at 3.6 @ 1.4v, idle is around 36-40, load is 50...watercooled.
