SKU CH-2T2C-80CJC

ECC registered DDR4 DIMM module with 16 GB capacity at 2133 MT/s for server platforms

  • 16 GB capacity for high-density server workloads
  • DDR4-2133 speed for reliable data throughput
  • ECC registered design protects data integrity
  • 2Rx4 organisation maximises memory bandwidth
  • Low-profile DIMM fits space-constrained chassis

Samsung DDR4 Server Memory

This is a 16GB DDR4-2133 registered ECC DIMM built for server platforms. It uses a 2Rx4 low-profile layout and carries the Samsung M393A2G40DB0-CPB part number. The module is supplied new and intended for qualified hardware only.

Suited For Qualified Server Builds

It fits administrators upgrading or repairing compatible enterprise systems that require registered ECC memory. Desktop or consumer laptop owners should look elsewhere because those platforms cannot use registered ECC DIMMs. Buyers who need unbuffered memory or a different speed grade must choose another part.

Capacity And Headroom

The single 16GB rank configuration adds substantial capacity to supported multi-slot servers. Headroom scales with the number of populated slots and the memory controller limits of the host system. Workloads that exceed the installed total will page to storage and lose performance.

Questions about this item

Does the M393A2G40DB0-CPB require a motherboard with registered DIMM slots and ECC support?

Yes, this module is registered ECC DDR4 memory and will only function in platforms that explicitly support registered ECC DIMMs.

Can the M393A2G40DB0-CPB be mixed with standard unbuffered non-ECC DDR4 modules?

No, registered ECC modules cannot be mixed with unbuffered non-ECC memory; the system will not boot or will disable the mismatched sticks.

How can I verify the M393A2G40DB0-CPB is running at 2133 MT/s after installation?

Check the memory speed reported in the system BIOS or a hardware utility such as CPU-Z; it should show 2133 MT/s for this module.
