Thanks for your reply. I feel that an upgrade processor may work with present mother board. Perhaps the following information may provide some help: Compaq Presario, Model: R1602HM...Sr1000, Serial # CNH5361B5N, System #EG643AA-ABA. I called HP talked with a lady across the World. The Rep. only wanted to sell me a new CPU.
If there is not an upgrade AMD Processor, I will continue on as is CPU.
Thank you for any information provided.
