HPE 8GB DDR4-2933 Registered DIMM

This HPE Smart Memory module delivers 8GB of DDR4 capacity at 2933 MHz with a registered signal. It uses a 288-pin form factor and operates at 1.20V. The single-rank 1Rx8 organisation supports high-density server configurations. It is built for HPE ProLiant platforms that require qualified memory.

Suits HPE servers needing registered ECC memory

This module fits administrators expanding memory in compatible HPE ProLiant servers that require registered DDR4 DIMMs. It is not suitable for workstations or desktop boards that accept only unbuffered UDIMMs. Buyers needing larger single-module capacities or different speed grades should verify their platform specifications first.

Registered DDR4 2933 with CL21 latency

The registered buffer and CL21 CAS latency define compatibility with the server memory controller. Systems designed for registered DDR4-2933 modules will recognise this part automatically. Always confirm the motherboard qualified vendor list before installation.

Questions about this item

How much power does the 1.20V DDR4 module draw under continuous load?

The module operates at 1.20V DDR4 voltage, which is the standard low-power level for DDR4 2933 registered memory.

Does my server need to support registered DDR4 2933 with CL21 timing to use this P00918-B21 kit?

Yes, the module is a 288-pin registered DDR4 2933 DIMM with CL21 CAS latency; the platform must accept registered DDR4 at that speed and timing.

Can I add this 1Rx8 registered stick to a channel that already has older registered DDR4 modules?

It can share a channel with other registered DDR4 DIMMs provided the server supports mixed ranks and runs all modules at a common supported speed.
