I have these specs from Everest:

There is no Hardware monitor or any other settings about overclock in my BIOS. Actually there are no settings at all, only few (Boot order, password, cooler speed).
I want to overclock FSB speed since I can't do a lot of things on my PC.

Yes, I have tried upgrading RAM, Hard drive but I i am sure that CPU is slowing system down.

I am 95% sure that it is possible to overclock this CPU. Also my CPU temperature is very cool and have no problems with heat.

So how can I overclock my current FSB speed or at least do something with performance?

This question was marked as an exact duplicate of an existing question.

It may be possible to overclock the CPU. But I doubt you can do it with that motherboard. Pre-built computers rarely have the functions needed to overclock the system made available in the BIOS. – Dracs Nov 14 '11 at 13:50
@Dracs - can I transfer this CPU to friends motherboard, overclock it and than transfer back? – Little Helper Nov 14 '11 at 13:53
Overclocking is controlled by the motherboard. The CPU will run at what speed the motherboard tells it to run at. The only thing I can think of is finding an unofficial BIOS for your motherboard. But flashing a bad BIOS could ruin the motherboard (I'm assuming HP doesn't offer things like DualBIOS). – Dracs Nov 14 '11 at 14:00
@techie007 Are you LOCA? It isn't a duplicate!!! Really other CPU, motherboard. Other situation! – Little Helper Nov 14 '11 at 14:06
I agree with what you are saying, but it's the same basic question "Can I OC my motherboard that doesn't offer any BIOS configuration options" - Check out the answer there, as much of it applies. Don't worry too much, it take 5 votes to close. Also see How to overclock Dual-Core CPU E5200? Lacking options in BIOS? – Ƭᴇcʜιᴇ007 Nov 14 '11 at 14:09
