Questions & Answers
What is the HP P00926-B21 64GB 4Rx4 DDR4-2933 CAS-21 ECC Load Reduced Smart Memory?
The HP P00926-B21 is a 64GB load-reduced DDR4 module running at 2933 MT/s with 21-cycle CAS latency, full ECC protection and HP Smart Memory features for ProLiant Gen10/Gen10+ servers.
Which HP servers are compatible with the P00926-B21 memory module?
This module is certified for HP ProLiant Gen10 and Gen10 Plus rack, tower and blade servers; always confirm in your server’s QuickSpec or memory configurator.
How does load-reduced memory differ from RDIMM?
Load-Reduced DIMMs use an Advanced Memory Buffer to reduce electrical load on the memory controller, enabling higher capacity modules and more DIMMs per channel than RDIMMs.
What does the 4Rx4 designation mean on this HP memory?
4Rx4 indicates a quad-rank x4 data organization, allowing higher capacity per module and optimized data-path efficiency for multi-processor servers.
What is HP Smart Memory and what benefits does it provide?
HP Smart Memory includes patented features like Online Spare, Memory Mirroring and Dynamic Thermal Sparing to boost reliability, availability and serviceability in ProLiant servers.
