Single 64GB ECC LRDIMM for Cisco UCS

This module is a 64GB DDR4 2400 PC4-19200 CL17 4Rx4 288-pin 1.2V ECC Load Reduced DIMM. It is built for Cisco UCS B260 M4 E7 v4 and B460 M4 E7 v4 servers and workstations that require load-reduced registered memory.

Verify platform and memory type before ordering

The system must support DDR4 ECC LRDIMM modules and accept 4Rx4 288-pin DIMMs at 1.2V. This memory cannot be mixed with unbuffered or standard ECC registered DIMMs. Confirm the server model matches the listed Cisco UCS B260 M4 E7 v4 or B460 M4 E7 v4 compatibility.

Sustained operation at rated speed and voltage

The module runs at DDR4 2400 with CL17 latency and 1.2V under continuous server workloads. JEDEC-compliant design and backward compatibility with 2133MHz allow stable long-term operation in multi-DIMM configurations typical of the target platforms.

Questions about this item

Does the 64GB 288-pin LRDIMM ship alone or with extra parts?

The module is supplied as a single 64GB DDR4 2400 CL17 4Rx4 1.2V ECC LRDIMM; no cables, brackets or additional components are included.

Should I pick the 64GB 4Rx4 LRDIMM or a different capacity for my Cisco UCS B260 M4 E7 v4?

This 64GB 4Rx4 LRDIMM is the only capacity listed for the Cisco UCS B260 M4 E7 v4 and B460 M4 E7 v4; other capacities are not offered in this product line.

What does the 2400MHz PC4-19200 rating deliver inside a Cisco UCS B460 M4 E7 v4?

The module runs at DDR4 2400 CL17 with 1.2V, providing ECC load-reduced operation; it is also backward compatible with 2133MHz systems.
