Help overclocking t2080

[mohammed51]

Hi All

I recently bought a laptop with the following spec's
CPU:T2080--1.78GHZ(533MHZFSB)--1mb L2 cache
GPU:Via chrome 9 hc integrated
Ram-2gb 667mhz ddr2 running at pc4200(266mhz)

My problem is i can overclock my cpu fsb to 149mhz resulting in 1.94ghz but when i raise my su FSB to anything over 150 my laptop stops responding.
Any suggestins

P.S. I am trying to overclock my laptop not DESKTOP

It stops responding because that's the usual limit for overclocking the pci bus. Once it gets too far out of spec, everything quits working properly.

Do some googling for intel + bsel + 133 to 166 and you should be able to locate a pin-mod to increase the fsb from 533 to 667. You'll need to do a little research on the mobo's chipset to make sure it supports the 667 fsb. If it doesn't the pin-mod can't work.

The pci bus is always locked to 33mhz and the agp bus to 66mhz this does not change because i use clockgen to overclock and can check this. My chipset supports upto 200fsb (quad pumped) and my memory can run upto 667mhz and is currently running at 600mhz. I have so far got 195mhz (12%)
overclock i beleive it is the voltage?

Any good programs out there that can change voltage and work on windows vista

Hi, how could you overclock T2080?

Sometimes Clockgen is just wrong. Usually 12-15% is the max you can overclock the PCI. Most Core2Duo's can get much more than 15% overclock on stock volts.

I still think your best option for a good overclock is to try a 133 to 166mhz BSEL pin-mid. That would get you to 2.16GHz which is the same as a T7400, so it should work with stock vcore.
