Hey everyone i just got a ram upgrade for my computer, the original ram was 512mb ddr2 pc4200 ram, and i got a second stick as an upgrade and its 1gb PC5300, but i put it in the second slot as to slow it down to match the 4200 speed, and my motherboard DOES support pc5300. Normally the problem is with the new stick, but in this case, its the OLD stick giving my problems, my computer isnt recognizing it. Its just showing the pc5300 and i do some gaming not alot but enough to need over 1bg of ram :P, so any help is appreciated :D Thx

BIOS ALWAYS automatically synchronize speed to that of the lowest speed stick. It seems that the OLD stick is not being detected. Try interchanging memory slots.

my guess..
the bus to the RAM can only run at one speed so both of the RAM chips have to operate at the same speed.
Result: you get the lower of the two.
Personally I'd just live with the 1GB working at the slower speed, but if it really bothers you take out the 512MB ram chip. Then verify that the bus now works at pc5300. Then sell off the slow ram on Ebay and buy some faster RAM :)
