Problem overcloking Intel Core 2 Duo T9500 on msi 620

Hello,

I recently upgraded my laptop MSI GX620. i changed a intel core 2 duo P7350 2ghz fsb 1066 with an Intel Core 2 Duo T9500 2.6GHz FSB 800. on my MSI GX620 there is a button that auto overclock raises a 2.3GHz processor, until the everything is fine. but after upgrading processor when I click on the button overclock the screen freezes and I must switch off power in the PC, restart all is well and the inverse function of economics which is down a Processor 800mhz works by against.

Is there someone who could help me understand this problem.

The tubo button automagically overclocks the processor. but it doesnt help you in doubling in frequency which older turbo buttons used, but it offers an extra 15% or so of power. with Intel Core 2 Duo T9500 you may get less power.

After updating the bios manually and drivers. Now i can use turbo soars now my CPU and Video Card upgraded fairly easily. I overclock GX620 CPU at 3 ghz which I assume means its cooling is sufficient.
