Module Capacity and Use
This single 8GB DDR4 module runs at 2666 MT/s with a CL19 latency and 1.20V operating voltage. It is an unbuffered, non-ECC DIMM built for standard desktop platforms that accept 288-pin memory. The 2Rx8 organisation suits general computing workloads and everyday multitasking.
Thermals and Power
Operating at the standard 1.20V keeps power draw low and heat output modest during typical desktop use. The module uses no active cooling, so it adds no fan noise to the system. Thermal performance will follow the airflow provided by the case and CPU cooler.
What the Package Changes
The package contains one 288-pin DIMM and no additional accessories or software. Installing this module adds 8GB of DDR4 capacity to a compatible motherboard with an available slot. No configuration utilities or driver discs are included or required.

Questions about this item
How do I install this 288-pin DDR4 module, and which orientation mistake should I avoid?
Align the notch on the module with the key in the motherboard slot, press straight down until both retention clips click, and do not force it backwards — the 288-pin key prevents reverse insertion.
What maintenance or replacement will this 8GB DDR4 2666 stick need later?
No routine maintenance is required; keep the contacts clean and replace the module only if memory errors appear or capacity becomes insufficient.
What limit appears first when this CL19 1.20V module runs sustained workloads?
The CL19 latency at 2666 MT/s sets the throughput ceiling before voltage or thermal limits become a factor.
