32 GB registered DDR4 ECC memory running at 2933 MHz with 1.2 V operation for HPE-compatible servers
This 32GB DDR4-2933 registered ECC module is built for HPE servers that require PC4-23400 speed. It operates at 1.20V with a 2Rx4 organisation and uses major-brand DRAM chips. The 288-pin DIMM is validated for 100% compatibility with the HPE P28225-B21 part number.
IT teams expanding or repairing HPE systems that call for registered ECC DDR4 at 2933MHz will find this module a direct fit. Buyers who need unbuffered DIMMs, non-ECC memory or a different voltage should look elsewhere. The 2Rx4 rank layout must match the platform's memory-configuration rules.
The registered ECC design and 2Rx4 rank at 1.20V are the decisive specifications for platform acceptance. Systems that require registered error-correcting memory at this exact rank and voltage will recognise the module without further configuration.

Yes, the 288-pin DDR4 form factor matches standard HPE server DIMM slots for registered memory.
Install in the slot sequence recommended by your HPE server manual; registered DIMMs often require specific channel population order.
Replace if system logs report correctable ECC errors increasing over time or if memory diagnostics fail during POST.
