Hi and Welcome!

for Dual Channel operation you always need pairs of matching memory modules. Please read the manual of your motherboard for additional details.

Your computer will probably run better without the two old 256mb sticks. Use the 1gb stick and add another if necessary.

ok thx alot for the advise and im using emachines t6212

Yep, get another 1GB RAM modul like that youhave or a new pair of modules.
