Jeans, First - thanks a lot! it worked ! Great !
Second: it gave me : 2 banks: Fundamental Memory type in both is DDR2 SDRAM on one bank: Maximum module speed 666MHz (PC2-5300) and on the second: Maximum module speed 400MHz (PC2-3200) So I guess my PC is working with the lowest speed (400 Mhz) for both RAM sticks (and I should consider upgrading). Another thing which occurred to me after running this: what is (PC2-5300) in first bank and (PC2-3200) in the second ? does this has anything to do with speed?
