Athlon 64 3000+ 2.0 GHz:
Memory Installed 512 GB (1 x 512)
Maximum allowed 2.0 GB (2 X 1 GB) requires the replacement of the installed 512 MB DIMM Speed supported PC3200 MB/sec
Type 184 pin, DDR SDRAM DIMM slots Two
Open DIMM slots One
You need PC3200 (DDR400) DIMMs, which can be installed singly or in pairs. If you only have 384MB you have 1 x 128M and 1 x 256MB.
You can upgrade to 2 x 1GB for 2GB total, but trust me, it won't make THAT computer much faster.
