SAMSUNG M378A1K43CB2-CTD 8 GB DDR4 2666 MHz desktop RAM

SKU CH-DCBP-RWY33

An 8 GB DDR4 desktop memory module running at 2666 MHz with a 288-pin DIMM form factor

  • 8 GB capacity for responsive multitasking
  • 2666 MHz DDR4 speed for fast data transfer
  • PC4-21300 bandwidth for high throughput
  • 288-pin DIMM fits standard desktop slots
  • Single-rank 1Rx8 layout for broad compatibility

8 GB DDR4 2666 MHz Module

This 8 GB DDR4 module runs at 2666 MHz and fits standard 288-pin DIMM slots. It is built for desktop systems that need a single, reliable memory stick for everyday computing tasks. The PC4-21300 rating matches the stated speed and density.

Sustained Load Behaviour

The module operates at its rated 2666 MHz frequency under continuous workloads without thermal throttling or downclocking. Standard JEDEC timings keep latency stable during long rendering, compilation or virtualisation sessions. Single-rank 1Rx8 organisation helps maintain consistent bandwidth across extended use.

DDR4 Interface Limits

The DDR4 interface tops out at the 2666 MHz data rate this stick provides, so faster memory controllers cannot push it further. Total capacity is fixed at 8 GB, limiting multi-tasking headroom for memory-heavy workloads. Dual-channel bandwidth requires a second identical module, which is not included.

Questions about this item

Does the 2666 MHz DDR4 module run hot or draw extra power during all-day workloads?

Standard DDR4 operation at 2666 MHz stays within JEDEC power limits, so heat and draw remain low even under continuous use.

Will my motherboard need a 288-pin DDR4 slot to accept this stick?

Yes, the module uses the 288-pin DIMM form factor, so a compatible DDR4 desktop slot is required.

Can I install this alongside older DDR4 modules in the same system?

Mixing modules is possible when all sticks share the DDR4 standard, though the system will run at the lowest common speed and timing.
