HP/Compaq system memory kit

This 2 GB kit contains two 1 GB DDR2 667 modules built for HP/Compaq workstations and servers. Each stick is a 240-pin DIMM with ECC and fully buffered operation. The kit runs at 1.80 V with a CL5 latency rating.

Check motherboard slots and memory type

Verify that your HP/Compaq system accepts 240-pin DDR2 fully buffered ECC DIMMs before ordering. The board must support registered memory and the PC2 5300 speed grade. Mixing unbuffered or non-ECC modules will prevent the system from posting.

Sustained load behaviour with ECC buffering

Under continuous workloads the fully buffered architecture reduces electrical loading on the memory controller. ECC corrects single-bit errors on the fly, maintaining data integrity during long compute sessions. The integrated heat spreader helps keep module temperatures stable over extended periods.

Questions about this item

What comes in the box and is anything else required?

The kit includes two 1 GB DDR2 667 FB-DIMM modules with heat spreaders. No extra parts are needed for installation.

Should I choose this 2 GB dual-channel kit or a single 2 GB module?

This 2 GB kit provides two matched 1 GB modules for dual-channel operation on HP/Compaq systems that require Fully Buffered ECC memory.

What does the DDR2 667 (PC2 5300) rating mean once the memory is installed?

The modules run at 667 MT/s with CL5 latency at 1.80 V, delivering the rated bandwidth when used in a compatible HP/Compaq workstation.
