128GB DDR4-2933 high-capacity server memory module
ECC registered 3DS RDIMM architecture
Quad-rank 4Rx4 logical organization
2-high 3DS stacked-DRAM construction
PC4-23466R | 288-pin | 1.2V
One physical 128GB memory module per quantity ordered

Compatibility: Requires a server that explicitly supports 128GB DDR4 3DS registered RDIMMs and the module’s 4Rx4 organization. Standard RDIMM support alone does not guarantee 3DS RDIMM compatibility. It is not compatible with UDIMM, ECC UDIMM, SODIMM, LRDIMM, DDR3 or DDR5 slots. Confirm the complete part number, processor generation, firmware and population rules before ordering.

** Lead Time: Due to current market volatility, approximately 4–5 weeks. Please contact us directly regarding any questions**

Is M393AAG40M3B-CYF Compatible With My System?

Before ordering, verify that your server supports 288-pin DDR4-2933 ECC 3DS registered RDIMMs, 128GB capacity per slot and a 4Rx4 logical organization. A server that supports conventional DDR4 RDIMMs does not necessarily support high-capacity 3DS RDIMMs.

This module is an ECC registered 3DS RDIMM, not an LRDIMM. Do not mix it with LRDIMMs, UDIMMs or SODIMMs. Compatibility can depend on the processor generation, server firmware, maximum memory capacity, supported ranks per channel and installed-module population.

The 4Rx4 designation describes the module’s logical rank and DRAM-width organization. The 2S2Rx4 notation identifies its stacked construction and rank arrangement. Neither designation means that multiple physical modules are included. Each quantity ordered includes one physical 128GB module.

The module may operate below 2933 MT/s when limited by the processor, motherboard, firmware or memory-population configuration. Because this exact part is discontinued, match the complete Samsung part number whenever the system or OEM requires an exact replacement.
