Problem : SiS M671DX+968 processor upgrade

I have an ASUS F70 notebook which comes with the chipset: SiS M671DX+968.  The processor is an Intel T6400.  I’d like to upgrade the process to perhaps a T9600 or a T9800.

I’m having difficulty finding what processors are compatible with the SiS M671DX+968 chipset.

I want to make sure I have a compatible processor before I shell out the money to do an upgrade.

Thanks experts!


Solution : SiS M671DX+968 processor upgrade

The 671DX chipset supports Core 2 Duo’s up to and including 1066MHz FSB with 45nm technology — so it will support the T9600/T9800 CPU’s you indicated you’d like to upgrade to.

HOWEVER … the link provided above lists the T9550 as the highest performance CPU supported by the F70 … so assuming that’s correct, I wouldn’t buy anything beyond that — the reason is simple:  it’s unlikely the F70’s BIOS has support for the higher-end CPUs.

In addition, you should upgrade to the latest BIOS  ** BEFORE **  you upgrade the CPU.    The original BIOS most likely does not have support for the later CPUs — and if you swap the chip first, you may find it no longer boots … you would then have to swap back to the original CPU;  upgrade the BIOS;  and then swap in the new CPU.
