Silicon Power SP004GBLFU266X02 4GB DDR4 2666MHz CL19 desktop RAM

SKU CH-M75R-3QWKZ MPN SP004GBLFU266X02

A 4 GB DDR4 UDIMM running at 2666 MHz with CL19 latency for faster application loading

  • 4 GB capacity adds headroom for multitasking
  • 2666 MHz DDR4 speed supports responsive application loading
  • CL19 latency keeps timing predictable for everyday workloads
  • Unbuffered UDIMM design fits standard desktop memory slots
  • DDR4 architecture delivers higher bandwidth than DDR3

Single 4 GB DDR4 module

This unregistered UDIMM provides four gigabytes of DDR4 memory at a rated 2666 MHz with CL19 latency. It targets desktop owners who need a basic capacity increase for everyday multitasking or office workloads.

Steady throughput on a single stick

Running at the advertised 2666 MHz the module delivers consistent bandwidth for sustained workloads rather than short bursts. The CL19 timing and single-rank layout keep latency predictable during extended sessions such as large spreadsheet calculations or background rendering.

Plain green PCB with standard gold fingers

The stick uses a conventional unbuffered DDR4 edge connector that slots into any desktop UDIMM socket keyed for DDR4. No heatsink or lighting is present, so clearance inside compact cases is not a concern and installation follows the usual notch alignment.

Questions about this item

How much heat or noise does the 2666MHz DDR4 module produce during all-day operation?

The unbuffered DDR4 UDIMM has no moving parts and runs silently. DDR4 technology is up to twice as fast as DDR3 while providing greater energy efficiency, so heat output stays low during continuous use.

What must my motherboard provide for this 4GB DDR4 stick to work?

The module requires a desktop DDR4 UDIMM slot that supports 2666MHz operation and non-ECC unregistered memory.

Can I run this CL19 DDR4 module alongside older DDR3 sticks I already own?

No. DDR4 and DDR3 use different physical slots and signalling, so they cannot be installed or operated together in the same system.
