Compatible HP Server Upgrade

This 4GB DDR3 1600MHz ECC UDIMM module replaces specific HP part numbers including 662609-571, 662609-574, 669238-071, 669322-B21, 669322-B212, 682413-001, 684034-001 and A2H32AV. It uses a 240-pin DIMM form factor and operates at the standard 1.5V voltage for DDR3 memory.

For ECC UDIMM Slots Only

Suitable for servers and workstations that accept unbuffered ECC DDR3 memory at PC3-12800 speed. Builders needing registered DIMMs, higher capacities, or different voltage requirements should verify their system documentation before ordering.

2Rx8 Rank Configuration

The dual-rank 2Rx8 organisation with CL11 latency determines compatibility with the memory controller. Systems requiring single-rank modules or a different rank structure will not support this stick.

Questions about this item

How much power does the 1.5V DDR3 module draw when the server runs all day?

The module operates at the standard DDR3 voltage of 1.5V; actual power draw depends on your server's workload and memory-controller efficiency.

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

A DDR3 DIMM slot that supports unbuffered ECC memory at 1600 MHz and can accept a 2Rx8 4 GB module.

Will this CL11 DDR3 stick work alongside older CL9 DDR3 modules I already have?

The system will run all modules at the slowest common speed and highest latency; mixing CL11 with CL9 means the CL9 sticks will operate at CL11 timings.
