Dark Mantis ,
Thank you for your welcome and information. I am disappointed at the result. I do have the Manual beside me everytime I make changes or add hardware. I was extremely hopeful that with new technology in Ram sticks and maybe update of BIOS I might have a chance . Page 15 of the manual states use memory modules of identical brand ,size,chips and speed. As previously stated I have successfully installed the two 1gig 800mhz sticks and it works well. Ah well to dream is to hope.
God Bless you and thanks for your time,
Spirit.
