Server-grade ECC RDIMM for 2933 MHz platforms

This 32 GB DDR4 module delivers registered ECC operation at 2933 MHz with a CL21 latency and 1.20 V power draw. The 2Rx4 organisation and Samsung chipset provide the error correction and signal integrity required by enterprise workloads. It is built for administrators who need dependable capacity expansion in qualified server and workstation boards.

Sustained throughput with registered buffering

The registered design places a buffer between the memory controller and the DRAM array, reducing electrical load during continuous read and write streams. ECC circuitry corrects single-bit errors on the fly, preventing silent data corruption during long compute jobs. At the standard 1.20 V the module maintains stability without the voltage excursions that can appear under prolonged stress.

Direct replacement for Samsung M393A4K40BB3-CVF

This unit matches the form factor, speed, rank layout and voltage of the Samsung reference part, so it slots into the same qualified memory lists without requalification. The upgrade is worthwhile when a system currently runs lower-capacity RDIMMs or non-ECC memory and the workload demands both higher density and error correction. Buyers who need unbuffered UDIMMs or faster JEDEC speeds should look elsewhere.

この商品に関する質問

How much heat does the 1.20 V DDR4 module generate when running all day?

At 1.20 V the DDR4 RDIMM operates at standard DDR4 voltage, so its thermal output is comparable to other registered DDR4 modules under sustained load.

What must my motherboard provide to use this 288-pin RDIMM?

The board needs a 288-pin DDR4 DIMM slot that supports registered ECC memory and can run at 2933 MHz.

Will this 2Rx4 CL21 stick work alongside my older 1Rx8 DDR4 modules?

Mixing 2Rx4 and 1Rx8 ranks is possible if the motherboard supports mixed-rank populations, but the system will run at the lowest common speed and latency.
