HP Mini 1000
The HP Mini 1000 uses a 1.60GHz Intel Atom N270 Processor, and includes 1 GB of memory as standard and supports up to 2 GB of DDR2(384 DIMM) RAM. The Mini has only one DIMM slot available. However due to Microsoft restrictions for Windows XP on netbooks, the XP versions are sold with up to 1 GB of RAM, even though the motherboard supports up to 2 GB and can be manually upgraded by the user. The RAM required is DDR2 (PC2-4200) at 533-MHz, or PC2-5300s, which runs at 667-MHz. The memory used must always be 200-pin SODIMM.
