I have PIII 733MHz processor with GA-BX2000+ (Intel 440BX AGPset) motherboard. my question is when I installed 256MB memory chip it only show 128MB, I thought may be it will not work with 256MB. I bought 128MB 2-chips but it shows only 64MB of each chip. what is the reason. for your information now I am using 64MB 2-chips and it is working fine. Is this BIOS problem. Kindly let me know bye
