Why cant I overclock at all?

Hi Guys,

I have an E2140 in an Asus P5B-MX, ive read in a few places that both overclock pretty well. Im using a single 1GB stick of DDR2 667 and yet I cant seem to overclock even slightly without getting BSOD etc..

Ive seen people getting 3Ghz on stock voltage and cooler and yet mines not even stable at 2Ghz ([email protected])

Can anyone point out an obvious mistake or shed some light?

Have you lowered the memory to 1:1 before starting to overclock?

daryll · 7 Nov 2007 at 17:36

Well thats what ive been trying to find since i posted, cant seem to find the FSB

RAM setting in the BIOS

CPUZ says it is 3:5..

Dont serpose uve managed to overclock a PCI-E socket on your gpu and ist crashing it?

Also whats your ram voltage?

Also i have a death adder without a mat. What you on bout?

Its oboard VGA, nothing in my PCIE slots.

Ram is at stock voltage, will check what that is.

Lol, mine doesnt work, it just wonders around the screen by itself without me touching it. Tried logging with Razer support and they just run round in circles, reinstall it, wash the lens with alcohol..nothing makes any dif

It's probably DRAM Frequency.

Only memory related option I can see is to set to either Auto, 533 or 667..

Cob · 7 Nov 2007 at 17:56

Well your current 3:5 will be the 667 option (probably what Auto is too). So change it to 533. It won't give you much headroom as it would appear that you can't go as low as 1:1 with the 800mhz CPU's on that board (which is understandable as 533 is PC2-4200 speeds and very few machines are fitted with DDR2 that's slower than that).

Ah thanks for that

Set it to 533 and now seems stable at 250x8.

Shame I cant get it to 1:1 though, I didnt buy the board for clocking though so nm.

When you say stock do you mean the specified voltage or the motherboards defult votages?

What sort of table you got? I presume you try it on a peice of paper to make sure its not faulty?
