OWC 16 GB DDR3 ECC RDIMM kit

This 16 GB kit contains two 8 GB DDR3 1333 registered ECC modules built for HP ProLiant DL585 G7, ML370 G6, SL160s G6 and SL160s G7 servers. The 240-pin RDIMMs run at 1.5 V with CL9 latency and a 2Rx4 organisation. They are designed for workloads that require error correction and registered signalling in compatible enterprise platforms.

Thermals and power in normal use

Each module operates at the standard 1.5 V DDR3 voltage without a heat spreader, relying on server chassis airflow for cooling. Registered buffering adds minimal latency while keeping signal integrity stable across full DIMM populations. Power draw remains within JEDEC limits for PC3-10600 registered memory during typical server workloads.

What the bundle changes

The matched pair enables dual-channel population on supported ProLiant boards, avoiding mixed-rank or mixed-speed configurations that can reduce stability. OWC tests every module in-house and backs the kit with a limited lifetime warranty and free technical support. The package replaces multiple HP part numbers including 500205071, 500205171, 500206071, 500662B21, 501536001, 593913B21, A0R56A, AM231A, AM328A, FX622AA and FX622UT.

Questions about this item

How do I install the 240-pin DDR3 RDIMMs in my ProLiant DL585 G7 and what step is often missed?

Power down the server, open the chassis, align each 240-pin module with the slot key and press firmly until both retention clips click; the step often missed is populating slots in the exact channel order shown in the server service guide.

What maintenance or replacement will the 16 GB DDR3 1333 ECC registered kit need over its service life?

No scheduled maintenance is required; if a module fails, replace the faulty 8 GB 2Rx4 RDIMM with an identical DDR3 1333 CL9 1.5 V registered DIMM to keep ECC protection intact.

What limit appears first when the ML370 G6 runs sustained workloads with this memory?

The memory subsystem caps at DDR3 1333 MT/s and CL9 latency, so bandwidth and latency ceilings are reached before the 16 GB capacity fills under typical server loads.
