Hynix 8GB DDR4-2666 UDIMM

This Hynix module is an 8 GB unbuffered DDR4 DIMM running at 2666 MT/s with a CAS latency of 17 and a standard voltage of 1.20 V. It uses a 288-pin form factor and ships as a dual-channel kit without a heat spreader. The green PCB carries major-brand chips in a single-rank 1Rx8 layout.

Ideal for basic desktop upgrades.

This memory suits owners of desktop boards that accept standard unbuffered DDR4 and want a straightforward capacity increase for everyday workloads. Builders who require error-correcting code, registered modules, or higher-speed XMP profiles should look at other parts.

Single-rank 1Rx8 organisation at 2666 MT/s

The module operates at DDR4-2666 with a CL17 timing and 1.20 V, using a single-rank 1Rx8 configuration that determines compatibility with many consumer chipsets. Verify that your motherboard supports this exact speed and rank structure before purchase.

Questions about this item

How much power does the 1.20V DDR4-2666 module draw when the system runs continuously?

The module operates at 1.20V, the standard DDR4 voltage, so power draw stays low during all-day use.

Does my motherboard need 288-pin DDR4 slots and XMP support to run this CL17 kit at 2666 MT/s?

A 288-pin DDR4 slot is required; the kit runs at 2666 MT/s CL17 without XMP, falling back to 2133 MT/s if the board does not enable the higher speed.

Will the green 1Rx8 sticks work alongside my older 2133 MT/s DDR4 DIMMs in dual-channel mode?

Yes, the 2666 MT/s modules will downclock to match 2133 MT/s sticks, and the 1Rx8 organisation keeps dual-channel operation intact.
