Compatible HP Server Memory

This A-Tech module is a 96GB DDR5 4800MHz ECC RDIMM built as a direct replacement for HP and HPE part numbers P66676-B21, P66896-1B1 and P67363-001. It uses a 288-pin registered DIMM form factor with 2Rx4 organisation and runs at 1.10V. The component targets administrators upgrading supported server or workstation platforms that require registered error-correcting memory.

Suited for validated HP platforms

The module suits environments that specifically call for the listed HP part numbers and DDR5 registered ECC technology. Systems that demand unbuffered UDIMMs, non-ECC memory, a different pin count, or a voltage other than 1.10V cannot use this part. Buyers should verify their hardware documentation for the exact part-number match before ordering.

Deciding specification: 2Rx4 registered ECC

The single detail that determines fit is the 2Rx4 registered ECC configuration combined with the DDR5 4800MHz speed and 1.10V operation. Only platforms qualified for this exact rank, buffering type and error-correction scheme will accept the module. Cross-reference the HP part numbers P66676-B21, P66896-1B1 and P67363-001 in your system manual to confirm compatibility.

Questions about this item

Does this 288-pin DDR5 RDIMM fit a standard server DIMM slot?

Yes, the module uses the 288-pin DDR5 RDIMM form factor that matches standard server memory slots.

What is the correct way to seat this 96GB module so the ECC RDIMM registers properly?

Align the notch with the slot key, press straight down until both retention clips click, and follow the system manual for channel population order.

Will the 1.1V DDR5 chips on this 2Rx4 module need active cooling or replacement over time?

The module has no heat spreader and runs at standard 1.1V; server airflow is sufficient and no scheduled replacement is required.
