32GB DDR3L ECC Registered Kit

This OWC upgrade kit delivers 32GB across two 16GB DDR3L 1600 modules built to the PC3L-12800 standard. Each stick is a 240-pin registered DIMM with CL11 latency, 1.35V operation and 2Rx4 organisation. ECC and registered buffering make it suitable for workloads that require error correction and signal stability.

For Lenovo ThinkServer RD540 RD630 RD640 TD330 TD340

The kit matches Lenovo part numbers 0C19535 46W0671 and 46W0672 and is validated for the listed ThinkServer models. It will not work in standard desktop computers and cannot be mixed with unbuffered memory. Buyers who need non-ECC unbuffered modules or a different form factor should look elsewhere.

Registered ECC DDR3L at 1.35V

The defining specification is the combination of registered ECC DDR3L technology at 1.35V in a 240-pin DIMM. Only systems that explicitly support registered ECC DDR3L can use this memory. Verify your platform documentation before purchase.

Perguntas sobre este artigo

Will these 2Rx4 registered DIMMs work alongside any existing unbuffered DDR3L modules I keep in my ThinkServer RD540?

No. The manufacturer highlights state that ECC registered memory cannot be mixed with unbuffered memory, so all slots must use registered modules.

How can I confirm the kit is running at DDR3L 1600 CL11 1.35V after installation?

Check the BIOS or UEFI memory information screen; it should report 1600 MT/s, CL11 timings and 1.35 V for each installed DIMM.

Does the 32 GB kit include only the two 16 GB modules or are any extra parts such as heat spreaders supplied?

The kit contains two 16 GB DDR3L 240-pin ECC registered DIMMs; no heat spreaders or additional accessories are included.
