16GB DDR4 ECC UDIMM for server upgrades

This 16 GB DDR4 2133 MHz ECC UDIMM module is built for servers and workstations that require error-correcting memory. It replaces Dell part numbers 370-ACFT, 370-ACMH, 370-ACOZ, 7XRW4, A8661096 and SNP7XRW4C/16G. The single 288-pin DIMM runs at 1.20 V with CL15 latency.

2Rx8 organisation under sustained load

The dual-rank 2Rx8 layout spreads memory accesses across two ranks, helping maintain throughput when the system runs memory-intensive workloads for extended periods. ECC circuitry detects and corrects single-bit errors on the fly, reducing the chance of data corruption during long compute jobs. Major-brand chips and A-Tech validation testing aim to deliver consistent stability.

DDR4 PC4-17000 interface limits

The module conforms to the DDR4 PC4-17000 standard, capping the data rate at 2133 MT/s and the voltage at 1.2 V. Systems that only support lower DDR4 speeds or registered DIMMs will not accept this unbuffered ECC UDIMM. Buyers needing registered memory or capacities beyond 16 GB per module must choose a different product.

Questions sur cet article

How much power does the 1.20V DDR4 module draw when the server runs continuously?

The module operates at the standard DDR4 voltage of 1.20V, which keeps power draw and heat low during all-day workloads.

What motherboard slot is required for this 288-pin ECC UDIMM to function?

It needs a DDR4 UDIMM slot that supports ECC unbuffered memory; the 288-pin keying prevents insertion into incompatible sockets.

Will this CL15 2133MHz stick work alongside older DDR4 modules already in my system?

Yes, it will run at the lowest common speed and latency, so mixing with slower or higher-latency DDR4 is stable but reduces overall bandwidth.
