64GB DDR4-2133 LRDIMM for Cisco Servers

This 64GB DDR4-2133 LRDIMM operates at 1.20V with ECC and Load Reduced architecture. It uses a 288-pin interface and a 4Rx4 rank configuration built with major brand chipsets. The module is 100% compatible with Cisco part number UCS-ML-1X644RU-A and meets OEM specifications for supported systems.

Suits Cisco UCS memory expansion.

This module suits administrators expanding memory in Cisco UCS servers that specifically require DDR4-2133 LRDIMMs. It is not for systems that only accept standard RDIMMs or UDIMMs, platforms limited to lower densities per slot, or builds needing speeds other than 2133 MT/s.

Load Reduced ECC architecture enables 64GB density

The Load Reduced ECC design reduces electrical load on the memory bus, allowing the 64GB capacity in a single 288-pin module at 1.20V. This specification decides compatibility; the system must support LRDIMM technology and the 4Rx4 organisation to recognise the full capacity.

Questions about this item

Does my server need 288-pin DDR4 slots to install this 64GB LRDIMM?

Yes, this module uses the standard 288-pin DDR4 form factor and requires a compatible server motherboard with DDR4 memory slots that support Load Reduced DIMMs.

Can I mix this 8Rx4 1.2V module with existing 4Rx4 RDIMMs in the same channel?

No, Load Reduced DIMMs and standard Registered DIMMs use different buffering architectures and cannot be mixed in the same memory channel or system.

How do I confirm the module is running at PC4-17000 speed after installation?

Check the system BIOS or UEFI memory information screen; it should report the module operating at 2133 MT/s with the correct 64GB capacity and ECC status enabled.
