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.
