Server-grade DDR3L upgrade kit

This OWC kit supplies 32 GB of DDR3L 1600 memory as two 16 GB registered ECC RDIMMs built for Lenovo System x3300 M4, x3500 M4, x3530 M4, x3550 M4 and x3630 M4 servers. The modules run at 1.35 V with CL11 latency and a 2Rx4 organisation. They are intended for administrators who need to expand capacity in supported workstation or server chassis.

DDR3L 1600 registered ECC limits

The DDR3L 1600 standard tops out at PC3L-12800 bandwidth and requires a platform that accepts registered ECC DIMMs; it will not work in systems that only support unbuffered memory. Mixing registered and unbuffered modules is not supported, so the whole memory population must match this type. The 240-pin form factor fits only sockets wired for DDR3L registered operation.

32 GB capacity for virtualised workloads

Two 16 GB ranks give 32 GB total, which suits moderate virtualisation, database caching and multi-user file services on the listed Lenovo models. Workloads that demand larger per-socket footprints or higher memory frequencies will exceed what this DDR3L 1600 kit can deliver. Buyers needing more than 32 GB per channel or faster transfer rates must look beyond the DDR3L platform.

Questions about this item

Should I pick the 32GB kit or buy single 16GB modules for my Lenovo System x3550 M4?

The kit contains two matched 16GB modules totalling 32GB, which is the simplest way to populate a pair of slots on the x3550 M4 and keep dual-channel performance balanced.

What does the DDR3L 1600 CL11 rating actually deliver once the modules are installed in a System x3630 M4?

The server will run the memory at 1600 MT/s with a CAS latency of 11 cycles at 1.35 V, giving the rated PC3L-12800 throughput for ECC registered workloads.

Will the 240-pin DDR3L RDIMM interface work with the registered DIMM slots in a Lenovo System x3300 M4?

Yes, the 240-pin DDR3L registered DIMMs are designed for the x3300 M4's RDIMM slots and provide ECC error correction at the supported 1.35 V level.
