Hey guys, im new so try and be kind

My processor is a Core Duo e6750 (2.66GHz) and i finally plucked up the courage and tried to overclock it last week. It has a stock cooler on and cased in an Antec 900.

i got it up to 3.1ghz, by changing the FSB and raising the cpu voltages up from 1.23 to 1.26.

I ran some tests and it idled at around 40, and load around 70. However its not stable, it keeps crashing. I've read the guide on the sticky, but still confused on what to do.

Im at university at the moment, and at home is a new cpu cooler waiting for me.

any help would be appreciated.
 
thanks, whats a safe voltage?
and if i increase the FSB, do i need to decrease the frequency of the ram proportionally??

thanks

Also, if the volts go up, wont the temperature aswell??
since my cpu temp is quite high already

thanks for advise, sorry for the many questions, im just tryin to learn.

i've set everything back to stock for now, wen i get home tomoz i'll bumb it up to 3.1ghz again and this time with 1.35v.

Can anyone explain why i need to slow down my ram if i increase my FSB?
 
ohh makes sense

soo glad i found this site, easy to get answers :D

soo do u know the maths for the decrease in RAM? so say i increase my cpu to 3.1, what would i decrease my RAM to? my ram is 800mhz
 
thanks for advice.

at the moment i've set everything back to stock, and increased my FSB to 375 with x8 multipliyer to give me 3GHz, temps are staying below 60 degrees with full load on stock cooler, so im quite happy.

This is where im confused now. i've decreased my ram speed from 800 to 667. im not entirely sure why i put it down to that speed.

If my FSB is below 400, can i keep my ram at 800 or do i still have to decrease it?
 
hey guys, just an update

Stock Vcore, Ram at 667 Mhz. CPU at 3.1Ghz, temps were 47/65, but it crashed while being tested.

Should i just increase the Vcore to like 1.35v and try again?
 
hey guys, just an update.
i installed an Asus 88 cpu cooler, and got a new coolermaster 832 case.

At 3.1Ghz
stock cooler: 47/65
New cooler: 27/36

very very happy with results, i think i have another 30 degrees to play with at the moment. However i have a slight feeling that these temps are abit low. anyone agree?

thanks
 
hey, im using speedfan, and OCCT, and both show same temperatures

just an update, i set the CPU to 3.2ghz, Vcore to 1.5v, but it kept crashing on the loading screen to windows

i had to set my ram speed to 633mhz for it to boot in. Is there any point increasing my cpu speed further if i have to decrease my ram speed that much??

thanks
 
i tried bumping up my ram volts to 2v, and still no luck. Windows just doesnt boot up when i set it to 3.2ghz. i played around with the ram speeds aswell, but no luck

Im not sure my bios has a n/b voltage setting
mayb i can play around with the timing?
 
i think its only x8 multi. i'll set it to x7 and keep increasing and i'll post my results

so is it my motherboard thats holding me back from overclocking higher?
