8GB DDR4 2666MHz Desktop Module

This 8GB DDR4 module runs at 2666MHz with a CAS latency of 19 and operates at the standard 1.20V. It is an unbuffered, non-ECC DIMM built with major-brand chips for desktop systems.

Direct Replacement for Listed Crucial Parts

The module is validated as a compatible equivalent for specific Crucial part numbers including CT8G4DFRA266, CT8G4DFS8266, BLS8G4D26BFSTK, BLS8G4D26BFSBK, CT4K8G4DFS8266, and CT2K8G4DFS8266. This ensures drop-in compatibility for systems originally configured with those kits.

Suits AMD and Intel Desktop Upgrades

The memory is recommended for AMD and Intel desktop platforms that support DDR4 2666MHz UDIMMs. Buyers needing ECC, registered modules, or speeds beyond 2666MHz should select a different specification.

Questions about this item

Will the 1Rx8 DDR4 module need any firmware updates or chip replacements over time?

No firmware or chip replacements are required; the 1Rx8 DDR4 DIMM is a solid-state component with no moving parts or field-updatable firmware.

What electrical limit appears first when the 2666 MHz module runs continuously at full load?

The 1.20 V supply rail and the DDR4 JEDEC thermal envelope are the first limits; the module is rated for continuous operation within those bounds.

How much heat and fan noise does the 288-pin DDR4 stick add when the system runs all day?

The unbuffered 1.2 V DDR4 DIMM generates minimal heat and has no fan; any audible noise comes from the chassis fans responding to overall system temperature.
