A-Tech 256GB (2x128GB) DDR4 2933 ECC RDIMM 2S2Rx4 3DS Server RAM

High-capacity DDR4 server kit

This A-Tech kit delivers 256 GB of DDR4 2933 ECC registered memory across two 128 GB modules. It is built for servers and workstations that require registered DIMMs with quad-rank 3DS/TSV organisation. The modules run at 1.2 V with CL21 latency and use major-brand chips for stable operation under heavy workloads. The dual-channel configuration helps maximise throughput on supported platforms.

Verify registered DIMM support

Confirm that your system accepts DDR4 registered ECC RDIMMs in a 288-pin form factor before ordering. Desktop and laptop platforms cannot use these modules because they require unbuffered memory. Check the motherboard or server manual for qualified memory lists, maximum capacity per slot, and correct population rules for quad-rank 3DS modules. Ensure the firmware and BIOS versions support the 2933 MT/s speed and 4Rx4 rank structure.

Suits memory-intensive server roles

This kit suits administrators expanding virtualisation hosts, database servers or compute nodes that benefit from large registered ECC capacity. It is not for desktop PCs, laptops or consumer workstations that only accept unbuffered UDIMMs. Systems limited to lower ranks per channel or lacking 3DS/TSV support should look at lower-density registered kits instead.
