SAMSUNG M393B2G70DB0-CMA 16GB DDR3-1866 LP ECC REG

SKU CH-4MKK-3FRE1

16 GB DDR3-1866 LP ECC registered memory module for server and workstation use

  • Server-grade reliability with ECC registered design
  • High-density 16GB capacity for demanding workloads
  • DDR3-1866 speed supports fast data throughput
  • Low-profile form factor fits space-constrained systems
  • Samsung manufacturing ensures consistent quality

Server memory module

This 16 GB DDR3 module runs at 1866 MT/s and includes ECC and registered buffering for data integrity in multi-socket systems. The low-profile height fits dense chassis where vertical clearance is limited. It is intended for qualified server and workstation platforms only.

Sustained throughput

Registered signalling reduces electrical load on the memory controller so bandwidth remains stable during long compute jobs. ECC corrects single-bit errors on the fly without halting the workload. The combination suits virtualisation hosts and database servers that run continuously.

Build and fit

Low-profile PCB clears oversized CPU coolers and tightly spaced DIMM slots in 1U and blade enclosures. Gold edge contacts resist oxidation through repeated thermal cycles. OEM packaging assumes installation by qualified technicians rather than retail end-users.

Questions about this item

How much power does the 16 GB DDR3-1866 LP ECC REG module draw when running continuously?

The LP (low-profile) DDR3-1866 registered ECC module operates at the standard DDR3 voltage, so its power draw stays within the normal range for server memory of this speed and capacity.

Does my motherboard need to support registered ECC DDR3 for the M393B2G70DB0-CMA to function?

Yes, the module is a registered ECC DDR3 DIMM, so the board must accept registered error-correcting memory; standard unbuffered desktop slots will not work.

Can I add this 16 GB DDR3-1866 registered ECC stick alongside older unbuffered DDR3 modules?

No, registered and unbuffered DDR3 cannot be mixed on the same channel; the system requires all installed modules to be registered ECC for this stick to operate.
