Server DDR4 ECC RDIMM kit

This A-Tech kit delivers 512 GB of DDR4 2933 memory across four 128 GB modules. It is built for servers and workstations that require registered ECC DIMMs. The kit uses quad-rank 3DS chips on a 288-pin form factor. It runs at standard 1.2 V DDR4 voltage.

Quad-rank 3DS registered specification

Each module is a 2S2Rx4 (4Rx4) 3DS/TSV registered DIMM with CL21 latency at PC4-23400 speed. The quad-rank design demands a platform that supports 3DS memory topology. Systems limited to dual-rank or single-rank modules will not recognise the full capacity. Compatibility must be confirmed against the motherboard qualified-vendor list before purchase.

Suited for high-density server builds

This kit fits administrators expanding memory in DDR4 servers that accept quad-rank 3DS RDIMMs. It is not for desktop or laptop computers, which lack registered ECC support. It is also unsuitable for workstations restricted to dual-rank modules or lower maximum DIMM capacities. Buyers needing non-ECC or unbuffered memory should look elsewhere.

Questions sur cet article

What does the 512 GB quad-channel kit deliver in a real server?

The kit provides four 128 GB DDR4 2933 registered DIMMs, giving a total of 512 GB of ECC memory that runs at 1.20 V with CL21 latency for data-integrity workloads.

What does the PC4-23400 DDR4 2933 interface cap in practice?

The modules operate at DDR4 2933 MT/s (PC4-23400) with ECC and registered buffering, so the memory controller can sustain that transfer rate across each populated channel.

What does the 288-pin 2S2Rx4 3DS form factor need to fit?

Each module is a 288-pin DDR4 RDIMM using 3DS/TSV quad-rank x4 chips; it requires a server or workstation board with registered DDR4 DIMM slots that support 2S2Rx4 (4Rx4) 3DS modules.
