A-Tech 64GB DDR4 2933 ECC RDIMM

This A-Tech module delivers 64GB of registered ECC DDR4 memory at 2933MHz with CL21 latency. It is built for server and workstation platforms that require registered DIMMs and error-correcting code for data integrity. The single 288-pin DIMM operates at the standard 1.20V DDR4 voltage. System administrators upgrading Cisco UCS equipment will find it matches the 15-106199-01 and UCS-MR-X64G2RT-H part numbers.

Suited for and not suited

This module suits IT professionals expanding memory in compatible Cisco UCS servers or similar registered-DIMM platforms that support DDR4 2933 ECC RDIMM 2Rx4 configurations. It is not suited for desktop PCs, laptops, or consumer motherboards that accept only unbuffered non-ECC memory. Buyers who need unregistered DIMMs, different capacities, or speeds other than 2933MHz should look at other memory types.

Deciding specification: 2Rx4 registered ECC

The 2Rx4 registered ECC organisation is the single specification that determines whether this module will function in your system. Only platforms designed for registered error-correcting DIMMs with this rank configuration can use it. Verify your server's qualified vendor list or memory population rules before purchase to ensure the 2Rx4 registered ECC design matches the required topology.

Questions about this item

Will this 288-pin DDR4 RDIMM fit my server's DIMM slots?

The module uses the standard 288-pin DDR4 DIMM form factor and 1.20V voltage, so it fits any server slot designed for DDR4 RDIMMs.

Do I need to populate specific channels or banks when installing this 2Rx4 registered module?

Install the RDIMM in the memory channel slots recommended by your server manual; the common mistake is mixing registered and unbuffered DIMMs in the same channel.

How can I tell when this ECC RDIMM should be replaced?

Monitor the system event log for corrected ECC error counts; a rising trend indicates the 64GB module is degrading and should be swapped out.
