SAMSUNG M393A4K40CB2-CTD 32GB DDR4-2666 LP ECC REG DIMM accessory

SKU CH-3JBS-15X0M

Provides 32 GB DDR4-2666 ECC registered memory for compatible servers and workstations

  • 32 GB capacity supports demanding server workloads
  • DDR4-2666 speed delivers responsive data throughput
  • Low-profile design fits space-constrained rackmount chassis
  • ECC registered architecture protects data integrity under load
  • Samsung manufacture ensures consistent component quality

Server-grade DDR4 memory module

This 32 GB DDR4-2666 registered DIMM is built for enterprise servers and workstations that require error-correcting code memory. The low-profile form factor fits dense chassis where vertical clearance is limited. It is not intended for consumer desktop or laptop platforms.

ECC registered DDR4 constraints

Registered buffering adds one clock cycle of latency and requires a motherboard chipset that supports registered DIMMs. ECC functionality only activates when the platform firmware enables it. Mixing registered and unbuffered modules on the same channel is not supported by the DDR4 standard.

Low-profile build and daily handling

The reduced-height PCB allows installation in 1U and blade systems without interfering with airflow or heatsink clearance. Gold-edge contacts resist oxidation during repeated seating cycles. The module carries no heat spreader, so case airflow must pass directly over the DRAM packages.

Questions about this item

Should I choose the 32 GB DDR4-2666 module or a lower capacity for my server?

The 32 GB DDR4-2666 LP ECC REG DIMM suits servers needing high capacity per slot; pick a smaller module only if your platform limits total memory or requires a different rank configuration.

What does the 2666 MT/s rating deliver once installed in a compatible system?

At 2666 MT/s the module transfers data at that peak rate, and the registered ECC design keeps signal integrity stable under continuous multi-threaded workloads.

How does the DDR4 interface and registered ECC layout affect real-world limits?

The DDR4 interface with registered ECC buffers address and command signals, allowing larger memory arrays per channel while the 2666 MT/s clock caps maximum bandwidth to that frequency.
