Hi,
I have an HP d4990y that came with 2GB PC6400 RAM. I dropped an additional pair of 1GB PC6400 sticks in for a total of 4GB (3.5 GB recognized), but the system now thinks I have PC5300 RAM (667 MHz). If I put one pair or the other the system recognizes the memory as PC6400 but all 4 sticks together I end up with PC5300.
There's nothing in the BIOS I can change regarding memory. Are the two pairs just incompatible with each other?
Thanks,
Paul
