Whats preventing me from OCing?

[Jamess]

hey
ive read on this forum that people are managing to get 3ghx+ out of their Q6600s so i tried myself and my computer just crashes and freezes when i try to increase the fsb even by a small ammount, whats going wrong?

spec:

Q6600- 2.4ghz stock
Nforce 650I motherboard
6gb 800mhx ram
500gb hd
xpert-vision 8800gt sonic 512mb
thermaltake tsunami case
and 530 watt psu

Nforce 650I motherboard

That narrows it down

Have you increased the Voltage to the processor?

Are you separating the memory, vid card and processor in bios?

If not then when you up the FSB your memory and vid card are being OC'd as well.

Separate them all (don’t leave on auto), run the Vid card @ 100% and the memory @ spec, then up the FSB and the voltage as needed.

Nforce 650i = utter crap then? ah ah heck and this will prevent me from getting close to 3ghz?

and i havent fiddled with the voltages yet as im not sure how much i should be increasing it by

and yea ive seperated them and its not on auto

All the nvidia chipsets are crap from the bytching that I have seen. The P35,38,45 and 48 OC the Q6600 to 3G with no voltage increase (usually a voltage decrease) and only setting the RAM to spec and the PCIe to 100Mhz.

If you have the cash, buy a cheap P45 and your troubles go away.

I'm running a Q6600 on a GA-P35-DQ6 at 3.2G (400 x 8) all settings on auto except PCIe @100 and RAM @ 2 in BIOS (1:1) 800.

You can OC the PX5/8 series mobos in your sleep.

Put the Voltage to 1.35 and see if it boots @ 400FSB... If it does try lowering the voltage to 1.3.
*** run realtemp, watch your temps close and shut-er-down if you reach 60-65.

If you do get a good boot run prime95 to see if it is stable.
*** run realtemp, watch your temps close and shut-er-down if you reach 60-65.

ok that sounds a good plan

because of the 650i sli mobo will i still be able to reach the 3ghz ? or even more or will the mobo not be able to handle it?

You probably will with enough tweaking.

here is an overclocking guide for the 680i. there will be some differences but it would be a good read and might help you figure out why you are having trouble:
