64GB DDR4-2666 ECC LRDIMM for servers

This 64GB module uses DDR4-2666 speed with CL15 latency and 1.20V operation. It is a 288-pin 4Rx4 registered LRDIMM with ECC for data integrity. The part is equivalent to Lenovo 01DE975 and uses major-brand chips. It suits administrators expanding memory in compatible Lenovo servers.

Check DDR4 slot count

Verify your server accepts 288-pin DDR4 LRDIMMs and supports 4Rx4 registered modules at 2666 MT/s. Confirm the memory controller can address 64GB per DIMM and that the total installed capacity stays within the platform limit. Ensure the BIOS is current enough for this density.

Runs at standard 1.20V with registered buffering

Registered signalling and 1.20V reduce electrical load on the memory bus. The LRDIMM buffer isolates ranks, helping signal integrity at high density. Typical server airflow keeps temperatures within spec without extra cooling. Power draw scales with the number of populated slots.

Questions sur cet article

What comes in the box with the 01DE975 64GB module and what must be sourced separately?

The box contains one 288-pin DDR4 LRDIMM rated 64GB PC4-21300 CL15 1.20V ECC registered 4Rx4. No brackets, cables or additional DIMMs are included; purchase matching modules separately to fill remaining slots.

How do I choose between the listed versions or capacities for the 01DE975?

This listing is a single 64GB 2666MHz 4Rx4 LRDIMM. Select this module when your server requires that exact density, rank and speed; choose a different capacity or rank only if your platform documentation specifies it.

What does the 2666MHz rating mean once the module is installed in a real server?

The module runs at DDR4-2666 (PC4-21300) with CL15 latency at 1.20V. Actual throughput depends on the memory controller, populated channels and BIOS settings; the rated speed is the maximum JEDEC standard frequency for this part.
