32GB DDR4 2933 ECC RDIMM for HP Servers

This 32GB registered DDR4 module operates at 2933MHz with CL21 latency and 1.20V voltage. It uses a 2Rx4 organisation and major-brand chips on a 288-pin DIMM. The part replaces HP part numbers P11770-001, P13210-001 and P28225-B21 in compatible server and workstation platforms.

Standard-voltage operation keeps thermals

At the JEDEC-standard 1.20V the module runs at normal DDR4 power levels without elevated heat output. Registered buffering reduces electrical load on the memory controller, helping maintain stable temperatures in densely populated servers. No extra cooling beyond standard chassis airflow is required.

Lifetime warranty and US-based support back

A-Tech validates every module through quality-assurance testing before shipment. The lifetime warranty covers the memory for as long as you own it, and United States technical support is available before, during and after purchase. Buyers who need capacity beyond a single 32GB module or who require non-ECC unbuffered memory for consumer platforms should look elsewhere.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click shut, then verify the system detects the full 32 GB at 2933 MHz in BIOS.

What maintenance or replacement will this ECC RDIMM need over time?

No routine maintenance is required; replace only if memory diagnostics report uncorrectable ECC errors or the module fails to initialise at 1.2 V.

What limit appears first when this CL21 2Rx4 module runs sustained workloads?

The CAS latency of 21 cycles at 2933 MHz sets the timing floor, so sustained throughput is bound by that latency before thermal or voltage limits are reached.
