Server memory kit for HP ProLiant Gen7 blades

This 64GB kit contains four 16GB DDR3 1333 registered ECC DIMMs built for HP ProLiant BL460c G7, BL490c G7, BL620c Gen7, BL680c Gen7 and BL685c Gen7 servers. It runs at 1.5V with CL9 latency and a 2Rx4 organisation. The modules are JEDEC and RoHS compliant and carry a limited lifetime warranty.

Steady throughput in multi-socket workloads

Registered buffering and ECC correction keep data integrity intact during continuous operation across all populated channels. The 1333 MT/s rate delivers consistent bandwidth for virtualisation, database and compute tasks without the error rates seen in unbuffered memory under sustained load.

Straightforward blade installation

Each 240-pin DIMM slots into the blade’s memory bays without tools; the kit is keyed to prevent misalignment. The only common issue is mixing these registered modules with unbuffered DIMMs, which the platform will not accept. All four sticks must match in capacity, speed and rank for the server to post correctly.

Questions about this item

Does the 1.5V DDR3 1333 kit run hotter or draw more power than lower-voltage modules in a ProLiant BL680c Gen7 running 24/7?

At 1.5V the modules follow the standard DDR3 1333 power envelope; registered ECC RDIMMs add negligible overhead versus unbuffered DIMMs, so thermal load stays within the blade's designed cooling capacity.

What server hardware must already be present for the 240-pin 2Rx4 RDIMMs to function?

A supported HP ProLiant blade — BL460c G7, BL490c G7, BL620c Gen7, BL680c Gen7 or BL685c Gen7 — with free DDR3 RDIMM slots and a BIOS that recognises 16 GB registered modules.

Can I keep my existing 8 GB unbuffered DDR3 DIMMs and add this 64 GB registered kit in the same ProLiant BL460c G7?

No — the manufacturer highlights state registered ECC memory cannot be mixed with unbuffered memory, so all slots must use registered modules of matching specification.
