Server DDR4 ECC RDIMM kit

This A-Tech kit delivers 64 GB of DDR4 2933 memory in four 16 GB registered DIMMs. Each module uses a 2Rx8 organisation with CL21 timings at 1.2 V. The kit targets servers and workstations that require ECC registered memory for data integrity.

Verify DDR4 registered support

Confirm that your system accepts DDR4 RDIMM modules and can run at 2933 MHz with CL21 latency. Desktop and laptop platforms will not accept these registered DIMMs. Consult the motherboard manual for correct quad-channel population rules before ordering.

Matched quad-channel kit

The four modules are tested together to ensure consistent timing and voltage across all channels. This matching reduces the risk of boot-time training failures and simplifies installation in quad-channel server platforms. No additional software or accessories are included.

Questions about this item

What comes in the box and is anything else needed to install it?

The box contains four 16 GB DDR4 2933 MHz ECC RDIMM modules for a total of 64 GB. No extra parts are required; install them directly into compatible 288-pin registered DIMM slots on a server or workstation motherboard.

How do I choose between the different capacities or speeds listed for this kit?

This kit is a single 64 GB quad-channel set running at 2933 MHz with CL21 latency. There are no alternative capacities or speeds in this listing, so select this kit when your system requires four matched 16 GB registered dual-rank modules at that specification.

What does the 2933 MHz rating mean for actual server performance?

The 2933 MHz (PC4-23400) rating is the maximum data transfer rate each module can sustain. In a real machine the memory will run at this speed only if the processor and motherboard support DDR4-2933 registered ECC; otherwise it will downclock to the highest supported speed.
