4GB 2x2GB Memory RAM Upgrade By XUM for HP Pavilion All-in-One MS219

Description

What is a DIMM? Dual in-line memory modules (DIMMs), used in desktop computers, are small circuit boards that can hold groups of memory chips. DIMMs provide a wider path with two rows of pins on a side, allowing for faster data transfer than single in-line memory modules (SIMMs). Like SIMMs, DIMMs might be manufactured single or double-sided. DIMMs do not have to be added in pairs and can be mixed with other DIMMs that have the same number of pins. For example, a 1-gigabyte (GB) DIMM can be added to the motherboard next to a 2 GB DIMM. What is a SODIMM? Small outline dual in-line memory modules (SO-DIMMs) are used in notebook computers and HP TouchSmart computers. They are smaller and thinner than other DIMMs, so are used when there is less space within a chassis.
