Server ECC RDIMM upgrade

This kit provides 16GB of DDR3L ECC registered memory in two 8GB modules. It runs at 1600MHz with CL11 latency and 1.35V operation. The 240-pin RDIMMs are built for Lenovo ThinkServer RD540, RD630, RD640, TD330 and TD340 systems. OWC tests every module in-house for reliability.

Unbuffered desktop builders should look elsewhere

These modules require a platform that supports registered ECC DDR3L memory. They will not work in standard desktop computers or consumer motherboards. Buyers needing unbuffered non-ECC RAM for a home PC must choose a different product. Mixing with unbuffered memory is not supported.

Registered ECC DDR3L at 1600MHz

The single specification that decides fit is the registered ECC DDR3L 1600MHz 240-pin form factor. Your server must accept 1Rx4 registered modules at 1.35V. Verify the memory slot population rules and maximum capacity per channel in your system manual before ordering.

Questions about this item

Will these 240-pin DDR3L RDIMMs fit the DIMM slots on my Lenovo ThinkServer RD540?

Yes, the 240-pin DDR3L form factor matches the RD540 memory slots and the kit is listed as compatible with that model.

Do I need to install the two 8GB modules in specific channel slots on the TD340, and which step is most often missed?

Populate the identical channel slots for each CPU; the step most often missed is seating both modules until the ejector clips click fully closed.

When should I expect to replace these 1.35V ECC registered modules in a continuously running RD630?

ECC registered DDR3L modules typically run for the server's service life; replace only if memory diagnostics report correctable errors that become uncorrectable.
