Product overview

The Samsung M393A4K40EB3-CWE is a 32GB DDR4-3200 ECC registered RDIMM, 2Rx4, native to Xeon Scalable Gen3 (Ice Lake) and AMD EPYC 7002/7003. Samsung is a first-source DRAM maker, so this is original-brand memory, not third-party assembled, and it runs full 3200 MT/s on current DDR4 platforms. (Note: this MPN is DDR4-3200; confirm any DDR5 labelling is corrected.)

Is it ECC registered?

Yes. It is a registered ECC module (RDIMM), which corrects single-bit errors and buffers command lines for stable operation at high DIMM counts.

Can I mix it with existing DIMMs?

Match type, rank and capacity. Mixed modules run at the slowest common speed, so buy a matched set for a full population.

What speed will it run at?

3200 or the platform limit. DDR4-3200 (PC4-25600). A faster module clocks down to the CPU and population limit.
