System-specific DDR5 upgrade kit

This 1 TB kit contains eight 128 GB DDR5 4800 CL40 4Rx4 ECC Registered RDIMMs built for HP ProLiant DL385 Gen11, DL560 Gen11, DX360 Gen11, DX365 Gen11 and ML350 Gen11 servers. It delivers registered ECC memory at 1.1 V for workloads that require data integrity and maximum capacity per slot.

Registered ECC DDR5 4800 CL40

The modules run at DDR5 4800 (PC5-38400) with CAS latency 40 and a 4Rx4 organisation, providing error-correcting registered operation that the target ProLiant platforms expect. They will not work in standard desktop boards and cannot be mixed with unbuffered or load-reduced DIMMs.

JEDEC and RoHS compliant kit

Every module meets JEDEC standards and RoHS requirements, giving a warranty-safe upgrade path for the listed servers. The eight-module pack fills all channels in a single purchase, avoiding the need to source individual sticks from multiple batches.

Perguntas sobre este artigo

What does the 4800 MT/s rating mean once the modules are installed in a ProLiant Gen11 server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V, delivering the JEDEC-standard data rate the platform expects for registered ECC memory.

How does the 288-pin DDR5 RDIMM interface affect bandwidth and capacity limits in these servers?

Each 288-pin registered DIMM presents a 4Rx4 organisation, so eight modules populate eight slots for a total of 1 TB while the memory controller governs maximum supported capacity per channel.

What physical clearance and slot layout do the 128 GB sticks need in a DL385, DL560, DX360, DX365 or ML350 Gen11?

Standard 288-pin RDIMM height with no heat spreader fits the server DIMM slots; eight modules occupy eight slots across the supported Gen11 platforms.
