Value Series 8GB DDR4 2666

This G.SKILL Value Series module provides 8GB of DDR4 memory rated at 2666 MT/s with CL19 timings. It suits builders assembling budget desktops for everyday office work, web browsing or light media playback. The single stick leaves additional slots open for future expansion when needed.

Unbuffered non-ECC 1.20V module

The stick is an unbuffered, non-ECC DIMM operating at the standard 1.20V DDR4 voltage. It plugs directly into any desktop board with DDR4 slots and requires no special cooling or voltage tweaks. Validated platforms include AMD X570, X470, B550, B450 and Intel Z790, Z690, Z590, Z490, Z390, Z370, Z270, Z170 chipsets.

Steady 2666 MT/s throughput

Under sustained load the memory maintains its rated 2666 MT/s transfer rate and 19-19-19-43 timings without throttling. The low 1.20V operation keeps power draw modest during long rendering or compilation sessions. Mixing this module with other kits is not supported and can cause instability.

FeaturesDo not mix memory kits. Memory kits are sold in matched kits that are designed to run together as a set. Mixing memory kits will result in stability issues or system failure.
Memory kits will boot at the SPD speed at default BIOS settings with compatible hardware.
Usage in any manner inconsistent with manufacturer specifications, warnings, designs, or recommendations will result lower speeds, system instability, or damage to the system or its components.

Questions about this item

Does the CL19 latency limit throughput during long workloads?

The module runs at CL19 with 19-19-19-43 timings at DDR4 2666, so latency stays consistent under sustained use.

How much heat or power does the 1.20V stick draw all day?

At 1.20V standard DDR4 voltage the module draws minimal power and runs cool without a heatsink during continuous operation.

Which motherboard chipsets must I already have for this DDR4 2666 kit to work?

Validated platforms include AMD X570, X470, B550, B450 and Intel Z790, Z690, Z590, Z490, Z390, Z370, Z270, Z170 DDR4 boards.
