32GB DDR5 PC5-4800B ECC RDIMM

The 32GB DDR5 PC5-4800B ECC RDIMM is a 32 GB DDR5 ECC server memory module rated at 4800 MT/s, part code PC5-4800B. It works in HPE ProLiant Gen11 servers. RDIMM is the standard server choice: a registered buffer, lower latency than LRDIMM and full ECC support. ECC means a single-bit memory error is corrected before it ever reaches your application. On a workstation that is a nice extra; on a server that runs for months without a reboot it is the difference between “a bit flipped” and “the database is corrupt”. One configuration detail that is often missed: populate channel by channel, not slot by slot. Six modules across three channels are considerably faster than six modules on one channel — the correct order is in the server model’s own memory-population guide. Also, if you mix modules of different speeds they all run at the speed of the slowest one.
