Supermicro Certified 8GB DDR4 Module

This module is built for desktop systems that require Supermicro certified memory. It delivers 8GB of DDR4 capacity in a single 288-pin DIMM using Samsung components. The non-ECC unbuffered design suits standard consumer and workstation boards.

Sustained Load Stability at 2666MHz

Operating at 1.20V with CL19 timings, the stick maintains its rated 2666 speed during extended workloads. Rigorous quality assurance testing ensures dependable performance without throttling when the system runs under continuous pressure.

Simple DIMM Installation

The 288-pin form factor fits any standard DDR4 desktop slot without extra cables or tools. Verifying the motherboard's supported memory specifications beforehand avoids the most common compatibility issues.

Questions about this item

How much heat and power does the 1.20V 2666MHz module draw when running all day?

The module operates at the standard DDR4 voltage of 1.20V with no heat spreader, so it runs cool and draws minimal power during continuous use.

What motherboard slot and memory type must I already have for this 288-pin DIMM to work?

You need a desktop motherboard with a DDR4 288-pin DIMM slot that supports non-ECC unbuffered memory at 2666MHz.

Will this CL19 Samsung module run stably alongside older DDR4 sticks I keep in the other slots?

Yes, it will downclock to match the slowest installed kit and run at the highest common CAS latency, provided the other sticks are also DDR4 non-ECC unbuffered.
