Server-ready ECC RDIMM

This 32GB DDR4 2133 module is built for HP server and workstation platforms that require registered ECC memory. It suits administrators upgrading compatible HP systems where data integrity and stability are priorities.

Sustained workload stability

Registered buffering and ECC correction keep data consistent during long compute jobs and virtualization tasks. The 1.20V operation and CL15 timing maintain steady throughput without the voltage spikes seen in unbuffered alternatives.

Straightforward DIMM installation

The 288-pin form factor seats in standard DDR4 RDIMM slots. Verify the system qualified-vendor list before purchase; mixing registered and unbuffered modules or exceeding the platform rank limit will prevent boot.

Questions sur cet article

How much power does the 1.20V DDR4 2133 module draw when the server runs continuously?

The module operates at the standard DDR4 voltage of 1.20V. Registered ECC DIMMs of this capacity typically consume a few watts each under load, so a fully populated chassis stays within normal server power budgets.

What must the system already provide for this 288-pin RDIMM to function?

The motherboard needs DDR4 DIMM slots that support registered ECC memory at 2133 MHz. The CPU and chipset must also be qualified for RDIMM operation; standard desktop boards without ECC or registered support will not work.

Can I mix this 2Rx4 CL15 stick with older HP-branded 728629 or 752370 modules in the same server?

Yes. This module is built as a direct equivalent for HP part numbers 728629, 752370, 753222, 774175 and Q0D69A, so it matches the same 2133 MHz, CL15, 1.2V registered ECC specification for compatible channel population.
