64GB DDR3L ECC Registered Kit for Lenovo

This 64GB kit contains four 16GB DDR3L 1600MHz registered DIMMs with ECC. The modules run at 1.35V with CL11 timing and a 2Rx4 organisation. They are built specifically for the Lenovo ThinkServer RD440 server platform.

Who this suits and who should look elsewhere

This kit suits administrators upgrading a ThinkServer RD440 that requires registered ECC memory at DDR3L voltage. It is not for workstations or desktops that accept only unbuffered non-ECC modules. It is also not for systems limited to 1.5V DDR3 or to single-rank DIMMs.

What to verify on your system before ordering

Confirm the server is a ThinkServer RD440 and that the memory slots support 240-pin registered DDR3L DIMMs. Check the installed CPU configuration because the maximum capacity of 192GB and the 12-slot limit apply only with two processors. Faster modules will down-clock to 1600MHz automatically.

Highlights

  • 64 GB total capacity across four 16 GB modules
  • DDR3L 1600 MHz speed rated at PC3L 12800
  • ECC registered design with CL11 11-11-11 timings
  • Low-voltage 1.35 V operation reduces server power draw
  • Validated for Lenovo ThinkServer RD440 with 2Rx4 chip organisation

Questions about this item

Does this kit need a server that takes 240-pin DDR3L registered DIMMs at 1.35V?

Yes. Each module is a 240-pin DDR3L registered DIMM rated for 1.35V, so the host system must support that exact form factor and voltage.

Will these modules run at 1600MHz in a ThinkServer RD440 that currently uses slower DDR3 memory?

The kit is rated for 1600MHz, but the server will clock the memory down to the highest speed supported by the installed processor and module population.

How can I confirm the full 64GB is recognised after installing the four 16GB sticks?

Check the system BIOS or operating system memory report; it should show 64GB total across the populated slots.
