8GB DDR4 2666MHz laptop memory

This single 8GB SODIMM module runs at 2666MHz with CL19 latency and 1.20V operation. It uses 260-pin DDR4 SO-DIMM form factor with unbuffered non-ECC architecture. The 1Rx8 organisation suits mainstream laptop and all-in-one upgrades.

Crucial CT8G4SFS8266 compatible replacement

The module is validated as a direct equivalent for the Crucial CT8G4SFS8266 part number. Major-brand DRAM chips are used throughout and every unit undergoes quality-assurance testing before shipment. This ensures reliable drop-in compatibility for supported systems.

Unbuffered 260-pin SO-DIMM build

Standard 1.2V DDR4 voltage keeps power draw low for mobile platforms. The 260-pin edge connector matches current-generation laptop slots without adapters. Buyers needing ECC, registered buffering, higher capacities or different speeds must select alternative modules.

Questions sur cet article

Will the CL19 timing require any adjustment or replacement over time?

No, the CL19 timing is fixed on the module and does not drift; the stick runs at 1.20 V and needs no maintenance or future replacement.

What limit appears first when the SODIMM runs continuously at 2666 MHz?

The 1Rx8 organisation and CL19 latency set the bandwidth ceiling before thermal or voltage limits are reached.

How much heat and power does the 1.20 V module produce during all-day use?

At 1.20 V the DDR4 SO-DIMM draws minimal power and generates low heat, staying within standard laptop thermal envelopes.
