Hi..I have some question, I have a motherboard whos RAM is for DDR PC266 and supports up to 2GB RAM.I let CBX Service upgrade it to 512MB DDR PC400 and it works and still my pc runs normally.My question is,I would like to add another 1GB DDR PC400 Memory,will it run and work normally like before or will it destroy my motherboard?I need ur suggestions...Thanks.
