Mobile Stability

I was talking to dip the other day with my prime fired up. My cpu is a 2600m doing a modest 2.4ghz 1.65vcore.

Don't mind the fan speeds, my mbm settings are screwy.
After running prime for about 2 hours, I thought i would try to lower vcore by another step to 1.625. So i did.
Windows bootloader showed up, i selected windows xp pro and BAMM!!! bsod. I was totally caught off guard since prime was extremely stable at 1.65.
In my old barton 2500+, it would be stable and slightly less stable if I decrease vcore. Windows exceptions would pop up and it wouldn't bsod on me. The mobile just goes from complete stable to completely unstable for some reason. Any1 else notice this?

wicth test have u used in prime (first, second , third)?
i think the bsod is memory related
you have pc 2700 rated at 333mhz and u are runnig at 200 fsb=400mhz
also to be sure that u are 100% stable run prime for 24 hours with 10 priority .
runing prime for 2 hours dont mean that u are 100% stable
the test may fail after some minutes or hours
