ram upgrading

[thanurabw]

Can I fix a KINGSTON PC2700 OR PC3200 256MB RAM CARD with a ELIXER PC2100 128MB RAM CARD.

Both rams at the same time.
also my motherboard supports only 2.5V DDR DIMM. So can I fix a PC3200.

you can match them together but they wont run at different speeds... eg. you can only run them at the lowest common speed

they should be 2.5v compatible
