what is the max CPU upgrade that the W350i (T-6815) supports? it currently has a Core2 Duo T5250 1.5GHz (667MHz bus) and I’m think up upgrading it to a T5850 2.13GHz (667MHz Bus) or to a T9500 2.6GHZ (800MHz Bus) the bios version on the GM965 chipset is 89.24, I think the chipset bus supports up to 800MHz cpus from my research but correct me if I’m wrong though

I think you can handle the core 2 quad CPUs.

Sorry for the very very late answer but in my standards if you look in this website http://www.cpu-upgrade.com/mb-Intel_(chi… the best cpu you can add and that goes with everyone with a 35 tdp cpu is a t9500. you also have to update the bios to the latest aswell.
