128GB DDR4 RDIMM for Servers

This Samsung M393AAG40M32-CAEBY module delivers 128GB of DDR4 memory in a single 288-pin RDIMM form factor. It is engineered for enterprise servers and workstations that require high-density registered ECC memory for mission-critical workloads.

2S2Rx4 3DS Architecture Enables Maximum Density

The 3D stacked die configuration with a 2S2Rx4 organisation allows this module to reach 128GB capacity within one slot. This quad-rank design is the specific feature that determines whether a platform can accept the module, as the memory controller must support 3DS quad-rank RDIMMs.

Suits Enterprise Platforms Only

This memory fits Dell PowerEdge, HPE ProLiant, Cisco UCS and Supermicro systems that explicitly support 128GB quad-rank 3DS RDIMMs. It will not work in consumer desktops or laptops, nor in servers that lack registered ECC support or quad-rank 3DS compatibility.

商品問答

What does the 128 GB capacity mean for a server workload?

The 128 GB module uses 3D stacked die architecture with a 2S2Rx4 layout to deliver maximum memory density in a single 288-pin RDIMM slot, suited for high-capacity enterprise deployments.

How does the PC4-3200AA designation limit real-world speed?

PC4-3200AA certifies operation at 3200 MHz on DDR4; the registered buffer and ECC logic add latency, so sustained throughput is capped at that rated frequency on qualified platforms.

What physical slot and clearance does this RDIMM require?

It fits a standard 288-pin DDR4 RDIMM socket; the registered design and tall heatspreader need full-height DIMM clearance and a motherboard that explicitly supports quad-rank 3DS modules.
