HP ProLiant BL45p G2 Server Memory

This 16 GB kit contains four 4 GB DDR2 667 MHz registered ECC DIMMs built for the HP ProLiant BL45p G2 server. The modules operate at 1.8 V with CL5 5-5-5 timings and use a 240-pin form factor. They are designed for mission-critical workloads that demand error correction and signal integrity.

Upgrade From Lower Capacity Or Non-ECC Modules

Replacing smaller or non-ECC DDR2 sticks with this registered kit adds error detection and supports the platform's maximum 64 GB limit across 16 sockets. The jump is worth it when applications require data integrity and the server populate all eight banks per processor node for optimal interleaving.

16 GB Registered ECC Capacity Headroom

Four dual-rank 2Rx4 modules deliver 16 GB and enable 4-way bank interleaving on each processor node. The kit scales toward the 64 GB ceiling but stops short of larger single-module densities. Workloads exceeding 16 GB per node will need higher-capacity registered DIMMs to continue scaling.

Domande su questo articolo

Will the 240-Pin DDR2 DIMMs fit the HP/Compaq ProLiant BL45p G2 blade server memory slots?

Yes, these 240-Pin DDR2 SDRAM modules are designed for the BL45p G2 which accepts up to 64 GB across 16 sockets.

What is the correct installation order for the four 4 GB registered DIMMs to keep bank interleaving active?

Install the kit in decreasing capacity with the largest kits in the banks furthest from each processor; all four modules are 4 GB dual-rank so populate the farthest bank first.

When should the registered ECC modules be replaced if the server starts logging corrected memory errors?

Replace modules when the system management log shows a rising count of corrected ECC events, indicating the 1.8 V DDR2 chips are degrading.
