Q6600 G0, P5N32E, I just can't OC even 3.0Ghz with stability. Help?

post #1 of 4
Thread Starter 
I just don't get it, really it's bugging me that everyone seems to be getting even small OC, but I just can't seem to get anything stable without the system locking at some point.

If you look at the the system, it should be able to give a little from the standard 2.4, but the best I got was 5 minutes up and running at 3.2Ghz, using 8x Multiplier at 1600mhz (Quad Pumped so 400mhz). This booted straight up and ran beautifully until I tested the system using 3D mark 06, which locked it up.

The temperatures were fine though as I checked with PC Probe II.

I tried Voltage Auto to start with, and got a read-out that the CPU was running at 1.49v.

So, as it locked I tried lowering the voltage (by manul control) to 1.35-1.4v, and the system got through the Post, but didn't reach the Window loading screen.

Ram timings are set at 5-5-5-15 and the memory is at 2.1v for the 4GB OCZ PC-8500 as the system wont boot at any less voltage because the slots for the am, when full are underpowered at the stock 1.9v.

So, as you can see from my post count, I'm a novice, who has followed loads of guides, but I cannot seem to join the elite of you who manage to OC.

Now I'll hold my hands up, working out the multipliers for you lot is easy, for me....nope, it really isn't

Seeing things like "dropping the Ram timings to 4-4-4-12, and setting it at 667mz, gives you with an 8x multiplier....... "

I know the 680i mobo has had it's problems, but I woul love to see even a 2.6 or 2.8 setting that would run with a little stability.

I honestly have gone through the guides to OC, but I am hoping someone has exactly the same board and chip as me, and could show me how/why I am going wrong.

BTW I have tried, linked, synced and unlinked in the memory with 1:1 and 5:4 ratio, but my god! it's p!$$ing me off!

Can anyone help?

Cheers, MP.

You won't get much more than 3.3Ghz with a Q6600 on this board unfortunately. This is down to the fact that the Asus boards don't allow adjustment of the GTL reference voltage from within the BIOS. Reference nVidia boards sold by EVGA and XFX fair slightly better, but even these are hindered with clocking Quads compared to Intel chipsets.

By the way, make sure you're useing the 1203 BIOS as this is the best BIOS for obtaining reasonable clocks with Core 2 Quads.

Try and up the PCIE Frequency to 110 and then see if you can go higher. It happened to me once on an ASUS mobo and it worked!

Yep This Is Correct .

Quads and this board are really a no go Core 2 Duos However are good overclockers
