I have a question about upgrading the CPU of a Sony Vaio V505 Laptop with a Pentium 4 Mobile Processor 2.40Ghz with a Pentium 4 3.00Ghz.

There specs are

P4-M 2.4 GHz 512 KB 400 MT/s 24× 1.3 V 35 W Socket 478
Northwood (130 nm)

P4 3.0 GHz 512 KB 400 MT/s 30× 1.55 V ~80 W Socket 478
Northwood (130 nm)

both CPUs work at the same FBS (400Mhz), and have the same size (130 nm) and are of the same socket (478) there are differences in voltage and the watts


Is This possible?
I doubt that the LAPTOPS motherboard is designed to supply enough power and even if it was, that processor would knock off at least 30mins from your battery life. Then taking heat dissipation into consideration from 2.3x extra power pumping through the CPU... I don't think that the laptops current cooling systems will cope.

That just my opinion THOUGH, I tend not to GET into laptop modding. They aren't made for it. Hopefully another member will be able to confirm for you. Quote from: smitty10492 on April 18, 2011, 07:49:38 PM
