Server ECC RDIMM kit

This OWC kit supplies 128 GB of DDR3L 1600 ECC registered memory in four 32 GB modules. It uses 240-pin DIMMs rated at CL11 and 1.35 V with a 4Rx4 organisation. The modules are JEDEC compliant and built for Supermicro SuperServer 8047R, 8048B, F617R2, F617R3 and F627G2 systems.

Workstation and server upgrades only

The registered ECC design suits workloads that demand error correction and signal integrity, such as virtualisation hosts or storage appliances. It will not work in standard desktop motherboards and cannot be mixed with unbuffered memory. Buyers needing consumer SO-DIMMs or non-ECC UDIMMs must select a different product.

Registered ECC DDR3L 1600 at 1.35 V

The combination of registered buffering, ECC and 1.35 V DDR3L signalling is the single specification that decides compatibility. Only platforms that explicitly support DDR3L RDIMM at this speed and voltage will accept the kit.

Questions about this item

Should I buy this 128GB kit or look for smaller capacity modules?

This kit provides 128GB total across four 32GB modules; choose it if your Supermicro server supports that density and you need the full capacity in a matched set.

What does the 1600MHz rating deliver once installed in a Supermicro SuperServer?

The modules run at DDR3L 1600 (PC3L-12800) with CL11 latency, giving the rated bandwidth when the server’s memory controller operates at that speed.

Is the 240-pin DDR3L interface compatible with standard desktop DDR3 slots?

No; these are 240-pin ECC Registered DDR3L DIMMs at 1.35V and will not work in unbuffered desktop DDR3 slots.
