SAMSUNG M393A2K43BB1-CTD 16GB DDR4 2666 2Rx8 RDIMM 1.2V 288-pin server RAM

SKU CH-1GNV-41D1P

16 GB DDR4 registered DIMM running at 2666 Mbps with 2Rx8 organisation and 1.2 V operation

  • 16 GB capacity supports demanding server workloads
  • DDR4 technology delivers 2666 Mbps data rates
  • Registered DIMM design adds signal integrity for stability
  • 2 V operation reduces power draw per module
  • 288-pin form factor fits standard DDR4 server slots

Server DDR4 RDIMM

This Samsung module provides 16 GB of registered DDR4 memory for server platforms. It operates at 2666 Mbps with a low 1.2 V supply and uses a 288-pin form factor. The dual-rank 2Rx8 organisation supports higher density per channel.

Registered ECC design

Registered buffering and ECC make this module suitable for multi-socket servers and virtualization hosts that require data integrity. Desktop motherboards and consumer laptops that lack RDIMM support cannot use this part. Builders needing non-ECC unbuffered DIMMs should look elsewhere.

2666 Mbps speed rating

The module runs at a 2666 Mbps data rate, which determines the peak memory bandwidth available to the CPU. Verify that the server platform and memory controller support this speed before installation. Mixing modules with different speeds will force the system to the lowest common rate.

Questions about this item

What slot and pin count does the 288-pin DDR4 RDIMM require?

The module fits a standard 288-pin DDR4 RDIMM slot on a server motherboard.

What is the correct way to seat the 1.2 V RDIMM so the retention clips lock?

Align the notch with the slot key, press down evenly on both ends until the side clips click into place.

When should I consider replacing the 16GB 2Rx8 module in a server?

Replace it if memory diagnostics report uncorrectable errors or if capacity no longer meets workload demands.
