SAMSUNG 8GB DDR4 2666MHz CL19 288-Pin DIMM desktop RAM

SKU CH-X4SE-JJ8XT

8GB DDR4 desktop memory module running at 2666MHz with CL19 latency and 1.2V operation

  • 8GB capacity keeps everyday workloads responsive
  • 2666 MHz DDR4 speed supports faster data throughput
  • CL19 latency balances timing with stable operation
  • 2V unbuffered design lowers power draw by up to 40%
  • 288-pin DIMM fits standard desktop memory slots

8GB DDR4 2666MHz Desktop Module

This Samsung module delivers 8GB of DDR4 memory at 2666MHz with CL19 timings. It uses the standard 288-pin DIMM form factor and runs at 1.2V. The unbuffered, non-ECC design suits mainstream desktop systems.

Suitable for general desktop upgrades and office PCs

Buyers who want more capacity per slot or lower latency timings should consider other options. Systems requiring ECC error correction or registered modules cannot use this stick. The single 8GB density may limit total memory on boards with few slots.

Check motherboard DDR4 support and free DIMM slots

Verify the board accepts 2666MHz unbuffered non-ECC memory at 1.2V. Confirm an open 288-pin slot exists and the CPU or chipset supports this speed. No special cooling clearance is required for this low-profile module.

Questions about this item

Does my motherboard need a 288-pin DDR4 slot to use this 8GB module?

Yes, the stick is a 288-pin DIMM built for DDR4 desktop boards, so the slot must match that pin count and memory type.

Will this CL19 2666MHz stick run with my existing 2133MHz DDR4 memory?

It will run alongside slower DDR4 modules; the system simply operates all sticks at the lowest common speed.

How can I confirm the module is running at 2666MHz after installation?

Check the memory speed in BIOS or a system-information tool such as CPU-Z; it should report 2666 MT/s when the XMP or default profile is active.
