Hi,

From the servica manual on page 1 we can see that the pentium processors compatible with your system are:

T4400, 2.20-GHz, 800-MHz FSB, TJ 100

T4300, 2.10-GHz, 800-MHz FSB, TJ 100

T4200, 2.00-GHz, 800-MHz FSB, TJ 100

Teh T4500 is also compatible

On page 71 we can see how to replace the processor.

The max RAM for your system is 4GB PC3-10600, 1333-MHz, DDR3

For best performance and dual channel suport it would be best to insert two identical sticks of Ram. Ther are kits available online for good prize specifically designed for this pupose.

On page 3 and 64 of service manual you can see RAM options.
