HI could anyone tell me what the fastest CPU I can use in a Optiplex GX240 please

I just took a 2.8Ghz cpu from a Optiplex gx270 and would like to know if it will work in my gx240 which currently has a 1.6Ghz processor in it.

Thanks !

Is GX240's mainboard based on Intel 845G Chipset?

478 Celeron D 310 2.13 GHz 533 MHz 256KB Prescott All

I don't know if it is very exact...but should be...

PS:

Ah there...

Celeron D probably needs to update mainboard's BIOS...

and the 800Mhz FSB CPU is NOT official supported by 845G...

WOW ! Thank you very much indeed.

I hadnt expectd such a comprehensive list

thanks

However, before you even think about "upgrading" or installing another CPU, take a look at this wiki page about popped capacitors. If you see any popped capacitors than it´s better to keep the money in your pocket and save it or a new computer...
