Hey I just bought a kingmicro 512mb DDR 3200 module DIMM 184 pin from bestbuy.I have a eMachines T3304. I just opened up my computer and cliped the memory stick in and closed it up and booted up my cpu. Nothing has changed. I still have 256mb installed. I know this memory is compatible with my PC and everything am i supose to reformat my pc or something? My cpu is not dual channel and i do NOT have to install matching pairs(As said by crucial.com).I tried taking the 256mb out and just stuck the 512mb by itself but when i booted it up i kept getting a bunch of beeping sounds.I have 2 memory slots both can hold up to 1gb each. i don't know about that color thing everyone was talking about for 4 slots. # Maximum Memory Capacity: 2048MB # Currently Installed Memory: 256MB # Available Memory Slots: 1 # Number of Banks: 2 # Dual Channel Support: No # CPU Manufacturer: AuthenticAMD # CPU Family: AMD Sempron(tm) Processor 3300+ Model 12, Stepping 2 heres a memory stick from crucial.com scan they recommended 1GB kit (512MBx2), 184-pin DIMM, DDR PC3200 memory module that sounds exactly like the one i just bought so wtf. I've also tried switching the memory sticks around but no luck. If anyone could help me out thanks a lot.
