Speed DDR4 2666 (PC4 21300)

  • 8GB capacity lets you run more apps simultaneously with a single 8GB module
  • DDR4 2666MHz speed moves data faster at PC4-21300 bandwidth
  • Low 1.2V voltage reduces power draw and heat output
  • Non-ECC unbuffered design fits standard desktop DIMM slots
  • 288-pin DDR4 form factor ensures physical compatibility with DDR4 motherboards

8GB DDR4 2666MHz UDIMM module

This single 8GB DDR4 module runs at 2666MHz with a CL19 latency and standard 1.2V operation. It uses the 288-pin UDIMM form factor and is non-ECC unbuffered memory. The module is designed for desktop PC upgrades and tested for AMD and Intel platform compatibility.

Standard voltage and unbuffered design

Operating at 1.20V, the module follows the DDR4 standard voltage specification for efficient power draw. The unbuffered, non-ECC design means it connects directly to the memory controller without additional buffering chips. This configuration typically results in straightforward thermal characteristics for standard desktop workloads.

Upgrade from lower capacity or slower DDR4

Replacing a 4GB module or slower DDR4 memory with this 8GB 2666MHz unit increases total system memory and bandwidth. The jump is worth it when your current memory limits multitasking or causes frequent paging to storage. Verify your motherboard supports DDR4 2666 before purchasing.

Soalan tentang produk ini

Will this module fit a motherboard that requires 288-pin DDR4 DIMMs?

Yes, it is a 288-pin DDR4 DIMM designed for desktop boards that accept unbuffered non-ECC memory.

Does the CL19 timing at 2666 MHz match the standard JEDEC profile for DDR4?

CL19 at 2666 MHz follows the standard JEDEC DDR4-2666 specification for unbuffered desktop modules.

Can I install this alongside existing DDR4 memory running at a different speed?

The system will run all modules at the speed of the slowest installed kit; mixing speeds is possible but not guaranteed to be stable.
