4GB DDR3 1866 ECC UDIMM for HP Servers

This 4GB DDR3 1866MHz PC3-14900 ECC UDIMM module uses a 240-pin DIMM form factor and operates at 1.5V with CL13 latency. It is built with major-brand chips in a 2Rx8 configuration for server and workstation systems.

Check DDR3 ECC UDIMM support and HP part numbers

Verify that your motherboard accepts DDR3 ECC unbuffered DIMMs at 1866MHz and 1.5V before ordering. This module replaces HP part numbers 708633-B21, 712287-071 and 715270-001, so cross-reference your system’s qualified-vendor list.

Standard-voltage DDR3 thermals and power draw

At 1.5V the module runs at standard DDR3 voltage, so power consumption and heat output are typical for unbuffered server memory. No active cooling is required beyond normal chassis airflow, and acoustic impact is negligible in normal operation.

Questions about this item

What comes in the box and do I need anything else to install this 240-pin DDR3 module?

The package contains one 4GB DDR3 1866 ECC UDIMM. No extra cables or brackets are required; the module plugs directly into a compatible 240-pin motherboard slot.

How do I choose between the listed HP part numbers 708633-B21, 712287-071 and 715270-001?

All three part numbers reference the same 4GB DDR3 1866 ECC UDIMM specification. Select the number that matches your server's service manual or the label on the module you are replacing.

What does the PC3-14900 rating mean for real-world server performance?

PC3-14900 indicates a peak transfer rate of 14,900 MB/s at 1866 MHz with CL13 latency, giving noticeably faster data throughput than lower-speed DDR3 modules in compatible platforms.
