8GB DDR3 ECC UDIMM for HP servers

This 8GB DDR3 1866MHz ECC unbuffered DIMM replaces HP part numbers 733736-001 and 708635-B21. It targets administrators upgrading compatible HP server or workstation platforms that require registered ECC memory. The single module delivers 8GB capacity at standard 1.5V operation.

CL13 latency at continuous throughput

Rated at PC3-14900 with CAS latency 13, the module maintains specified timing under sustained server workloads rather than only in brief bursts. ECC circuitry corrects single-bit errors on the fly, preserving data integrity during extended compute sessions. The 2Rx8 organisation supports stable operation across all populated slots.

240-pin installation with compatibility check

The 240-pin DIMM seats in standard DDR3 UDIMM slots without tools; alignment key prevents reverse insertion. Builders must verify the system supports unbuffered ECC DDR3 at 1866MHz and the exact HP part numbers listed, as registered or non-ECC variants will not function. No additional configuration is required beyond BIOS recognition.

Perguntas sobre este artigo

How much power does this 1.5 V DDR3 1866 module draw under continuous server load?

It operates at the standard DDR3 voltage of 1.50 V; actual power draw depends on the platform and workload but the module is rated for 1.5 V operation.

What must my motherboard provide to run this 240-pin ECC UDIMM?

A DDR3 DIMM slot that accepts 240-pin unbuffered ECC modules at 1.5 V and supports 1866 MT/s (PC3-14900) speeds.

Can I mix this 2Rx8 CL13 stick with other DDR3 ECC UDIMMs of different rank or speed?

Mixing ranks and speeds is possible if the motherboard supports it; the system will typically run all modules at the lowest common speed and timings.
