Description
The HP GL638AVR is a 512MB memory module utilizing DDR2 technology in a Fully Buffered DIMM (FB-DIMM) form factor. FB-DIMMs were commonly used in servers of the DDR2 era to overcome signal integrity limitations and allow for higher memory capacities and speeds. This module operates at a frequency of 667MHz, identified as PC2-5300, and has a CAS Latency of CL5. The 1Rx8 designation indicates it is a single-rank module with an 8-bit data width. FB-DIMMs include an Advanced Memory Buffer (AMB) chip on the module itself, which helps to amplify signals and reduce electrical loading on the memory controller. This specific memory module is designed for compatibility with certain HP server models that utilize DDR2 FB-DIMMs. While DDR2 technology is older, these modules were essential for providing adequate memory capacity and performance for servers of that generation, supporting various enterprise applications and operating systems.
