HP 64GB 4Rx4 PC4-2400T DDR4 Server RAM 805358-B21

64GB DDR4 server module

This HP 64GB DDR4 module uses a 4Rx4 organisation and runs at PC4-2400T speed. It is built for servers that need high memory density in each slot. The part suits administrators expanding virtualisation hosts or database nodes.

Sustained load behaviour

Under continuous workloads the 4Rx4 layout distributes requests across four ranks, helping to keep throughput steady. The registered design adds a clock cycle of buffering that stabilises signalling on heavily populated channels. Buyers who need ECC error correction will find it included. Builders who require lower latency for fewer ranks should consider a different configuration.
