8GB DDR4 2666MHz UDIMM

This 8GB DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. It uses a 1Rx8 unbuffered non-ECC design on a 288-pin PCB. The stick is built for standard desktop DIMM slots and carries Samsung DRAM components.

Check motherboard DDR4 slot

Verify that your board accepts DDR4 UDIMM modules and that the CPU memory controller supports 2666MHz operation. The module requires a standard 288-pin DDR4 slot and 1.20V supply. Confirm the platform can run non-ECC unbuffered memory at this speed before ordering.

Sustained throughput at rated frequency

Under continuous load the module maintains its 2666MHz data rate and CL19 timing at 1.20V. The unbuffered topology delivers consistent bandwidth for long rendering or compile sessions. Power draw stays at the rated voltage without thermal throttling on the DRAM chips.

Perguntas sobre este artigo

Does the 8 GB DDR4 2666 MHz module come alone or with extra parts?

The listing shows one 8 GB UDIMM; no cables, brackets or additional modules are included.

Should I pick the CL19 1.2 V stick or look for a different latency?

This single-rank 1Rx8 module runs at CL19 and 1.2 V; choose it when your board specifies that timing and voltage.

Will the PC4-21300 rating actually run at 2666 MT/s in my desktop?

The module is rated for 2666 MT/s at CL19; the final speed depends on the motherboard's memory controller and BIOS settings.
