Kingston DDR2, Micron / Elpida chips, dual channel compatibility

[me]

Hello,

I have 1 stick of Kingston KVR533D2N4/512 DDR2 on an Asus M2NPV-MX, and
wanted to buy another one, to run them together in dual channel mode.
However, the stick I have is about 2 years old and uses Micron D9DCN CB-37E
chips. The new sticks in the shops use Elpida E5108AJBG chips.
Can anyone tell me with some certainty whether these will be compatible?
Their respective spec sheets both say "16M words x 8 bits x 4 banks, 60-ball
FBGA, 1.8V, 1KB page size, row A0-13, column A0-9, burst length 4/8, CL
4/5/6, refresh cycles: 8192/64ms" (in fact, I can't really find any
difference), but is that enough to ensure compatibility?

Thanks in advance!

Marc.

No, to work in dual channel mode, the sticks have to have exactly the
same chips. They need to have exactly the same speed and because margins
are very small, chips from different brands won't switch at exactly the
same time. With the two stick you have, your pc will use 1GB, but it
will still be running in single channel mode.
