BIOS reset - are my overclocking settings correct?

Hi all,

Some time ago my BIOS settings were reset after a crash. When i bought the machine the cpu came pre-overclocked to 3.0ghz. I remember this as when i bought the system i opted for a 4gb ram setup instead of 2gb. I am sure i was told the advertised overclock of 3.3ghz would therefore be reduced to 3.0ghz due to going for 4gb over 2gb ram.

Now my problem is after my BIOS reset i loaded the 'ocuk' profile in BIOS which set the FSB to 368 and the multiplyer to x9 giving a core speed of 3312.

Not knowing much at all about the details involved in overclocking (thou i am trying to learn) do my settings look 'correct' for the setup i have atm, even thou i'm sure the OC was limited to 3ghz?

I'm using an Abit IP35 Pro motherboard. Temps don't seem too bad atm 65 CPU on load, 55-60 PWM. I just seem to have a slightly less stable system than before with occasional hard freeze ups inc mouse or keyboard, which requires a physical reboot.

Like i said i'm a novice and just want to know if my OC settings look 'right' for my spec. I don't want to push the machine too hard or damage something by not using the correct settings. I presume i can't just reduce the multiplyer to x8 to get a near 3ghz core speed?

Thanks all

p.s let me know if i have missed anything out.

volts on the vcore look a little high

run prime95 and check temps with core temp

It's an old 65nm chip don't forget, so the voltages seem about right.

I dont know what ram divider you have but at 1:1 you will have 2 x 368 = 736Hz OK for DDR2 6400 or above.

I would keep the multi at 9 and try 350Mhz = 3150MHz see if that cures the lock ups.

I assume it was set up originally at 333Mhz to get 3GHz (9 x 333) and maybe using 666MHz (2 x 333) RAM clock or even 1.2 x 666 = 800MHz with 1:1.2 divider.

Hey guys,

Thanks for the replies. Will give your suggestions a go and see what happens.

Looking at BIOS uGuru i see my RAM divider is 1.25. Current FSB of 368 gives me a 920 value.

At 333 FSB that's 833
At 350 FSB that's 875

Would those be acceptable values? And would i have to change voltages?

Cheers
Steve

are they not high anyway for those clocks.

would have thought 1.35-8 would have done that???

been a long time since i had a q6600
