The D4EC-2666-8G is a single 4 GB DDR4 module running at 2666 MHz, featuring a 288-pin DIMM form factor, CL19 latency, and 1.2 V operating voltage for desktop systems.
This module is compatible with any x86 desktop motherboard that supports DDR4 2666 MHz UDIMM memory and offers 288-pin DIMM slots. Check your motherboard’s QVL for full assurance.
Power off your PC, open the case, align the notch with the motherboard slot, insert the 288-pin DIMM at a 45° angle, press down until the latches click, then close the case.
Upgrading to DDR4-2666 delivers up to 25% higher bandwidth and improved power efficiency compared to DDR3, reducing load times and enhancing multitasking in modern applications.
You can mix brands if the modules share DDR4 type, speed (2666 MHz), voltage (1.2 V), and similar timings. For best results, use identical modules in dual-channel pairs.
The module operates at CAS latency CL19, offering a balanced latency-to-bandwidth ratio for smooth desktop performance and quick data access.
This DDR4 module runs at a standard 1.2 V, delivering lower power consumption and heat compared to previous-generation memory.
Yes. With 2666 MHz frequency and CL19 latency, this 4 GB module enhances frame rates and load times in most modern games when paired with a compatible CPU and GPU.
The D4EC-2666-8G supports standard JEDEC timings at 2666 MHz. It does not include proprietary XMP or EXPO overclocking profiles.
This RAM module comes with a limited lifetime warranty covering defects in materials and workmanship under normal use.
Reseat the module, test a different slot, update BIOS, verify BIOS detects DDR4-2666 memory, and ensure no bent pins. Contact support if issues persist.
Designed for continuous operation, the module offers a mean time between failures (MTBF) exceeding 1 million hours under normal desktop conditions.
No. This is a 288-pin DIMM designed for desktops. Laptops require SO-DIMM modules with 260 or 262 pins.
Yes. As long as your mini-ITX motherboard includes a standard 288-pin DDR4 slot, the module will fit any case that accommodates your motherboard and heatsink.
Check your motherboard’s specifications or BIOS memory settings. Look for DDR4 frequency listings or supported JEDEC profiles for 2666 MHz.
This DDR4 module is manufactured in our ISO-certified facilities, ensuring strict quality control and adherence to global electronics standards.
