T21 Upgrade

#1 Post by strekship » Thu Dec 02, 2004 6:26 pm

Would it be possable to upgrade the processor on a T21 to 1GHZ? Or at least 900mhz?

Yep!
I did it several times, have currently a T20 running smoothly with 900 Mhz.
I had upgraded the cooling system from the T20 to the one of the T22.
No problems so far. The motherboards of T20-T22 seems to be very similar.

Everything stable and nice going.

you need micro-pga2 socket.
go to intel processofinder and look for the right CPU and then google at ebay. You need 100 Mhz bus.
The 133 Mhz bus is only for the T23 (different chip set).
a 900Mhz mobile P3 would be around $40-50.
