HP 8GB 647899-B21 (1x8GB) Single Rank x4 PC3-12800R (DDR3-1600) Registered CAS-11 Memory Kit – (G8 Series)

The HP 647899-B21 is an 8GB DDR3 memory module designed for use in HP ProLiant G8 servers. This particular module has a single rank x4 configuration, which means that it has four memory chips on each side of the module arranged in a single rank.

The module operates at a frequency of 1600MHz (PC3-12800) and has a CAS latency of 11. The CAS latency refers to the time delay between the memory controller requesting data and the data becoming available, so a lower CAS latency can result in faster system performance.

The module uses registered ECC (Error-Correcting Code) memory technology, which can help detect and correct errors in memory operations. This can improve system stability and reduce the likelihood of data corruption.

The module also supports a maximum memory bandwidth of 12.8GB/s and operates at a voltage of 1.5V.
