Hello i have a P4 2.6Ghz with original 256MB DDR 333Mhz pc2700 C.L. 2.5 and i added 1GB DDR 400Mhz pc3200 and it is workin well. My question is could i add another 1GB DDR 400Mhz pc3200??? and if possible a 2nd one so i can get it to 3.25GB???? If you are wondering why, cause i want to play games and i want 2GB at least please help!

If you mix PC2700 with PC3200, ALL the RAM will run at PC2700 speed (166MHz). Does your CPU run at 133MHz (533MHz FSB) or 200MHz (800MHz FSB)? BTW, RAM isn't gonna help your gaming all that much is you have a crappy video card.

I found in lenovo page this: "Supports Intel Prescott Pentium 4 processors with 800MHz FSB" and i also installed Nvidia GeForce FX5500 which i am very happy with cause it has 256MB 128-bit and it improved very good my graphics. Do you recomend to withdraw de original 256MB memory and install the other one with 1GB so i can have both pc3200 memory???
