64 GB DDR3 ECC RDIMM kit

This OWC upgrade kit provides 64 GB of DDR3 ECC registered memory in a matched pair of 32 GB modules. It is built for HP ProLiant DL585 G7, ML370 G6, SL160s G6 and SL160s G7 servers that require registered DIMMs with error correction.

Registered DDR3 limits

Registered DDR3 1333 modules operate at 1.5 V with CL9 latency and a 4Rx4 organisation. They cannot be mixed with unbuffered memory and will not function in standard desktop platforms that lack registered memory support.

Check server generation and slots

Verify that your ProLiant model matches the listed G6 or G7 generations and that the memory slots accept 240-pin registered DIMMs. Confirm the maximum supported capacity per slot and the required population rules before ordering.
