I just reciently replaced my Pentium D 820 (2.8GHz) with a Intel Core 2 Duo E6600. (2.4ghz)

I am trying to squeeze every ounce of power out of my system, as it is quite out dated, and just barely runs current games.

Now I have gotten 3 Ghz out of my old Pentium D, so I was hoping to get at least 2.8GHz out of the Core 2 duo, because from what I have read it is a very easy CPU to overclock, and from my temputures, I should be able to go wayyy higher then what I have...

Currently my Core 2 duo is at 2.6GHz, and the temps max at 38 degrees C.

For the life of me I can't get my system to be stable above 2.6ghz.. It just crashes after a few mins.. Temps are always good. Never above 40. Hell.. The fan barley turns on (it used to run around 4000rpm with my old processor, now its on minimum, at 1800rpm)

I am thinking the problem might be a power issue, but I can not adjust the power level with my motherboard..

So I am thinking to get a new motherboard, if I can get one for under 100 bucks... (unless anyone knows a way to boost my current setup?)

my current motherboard is: AsRock 4coreDual-VSTA


Now if I were to get another Mobo, it would have to be compatable with all my current hardware....

Which is

PCI express gfx
DDR2 SDRAM
and both IDE, and SATA drives.

Does anyone have any recommendations for a mobo?

Thankyou!

PS - I am looking at the ASUS PK5. Is that a diecient mobo?
