Certified Supermicro DDR4 Module

This 8GB DDR4 2666MHz DIMM carries Supermicro certification under part number MEM-DR480L-CL01-UN26 and uses Micron components. It is built for desktop systems that require validated memory for stable operation in Supermicro platforms.

DDR4 2666 Standard Limits

The module runs at the JEDEC DDR4 2666 standard with a CL19 latency and 1.20V voltage. Speed and timing are fixed at these values, so the memory will not exceed the PC4-21300 data rate on any motherboard.

288-Pin Unbuffered Installation

Installation follows the standard 288-pin DIMM procedure: align the notch, press firmly until the retention clips lock, and verify seating. The most common issue is a partially seated module that prevents the system from posting.

Questions about this item

Should I choose the 8GB module or look for a different capacity?

This listing is for a single 8GB DDR4 2666MHz module. If your Supermicro system has free DIMM slots, adding one 8GB stick increases total memory by 8GB. For dual-channel performance, install two identical modules in matched slots.

What does the 2666MHz rating actually deliver in my desktop?

The module runs at 2666 MT/s with CL19 latency at 1.20V. In a compatible Supermicro board it will operate at that rated speed, giving 21300 MB/s peak bandwidth per module. Actual throughput depends on the memory controller and slot population.

Is the 288-pin DDR4 interface the limiting factor for speed?

The 288-pin DDR4 DIMM interface supports the module's native 2666MHz operation. The board's memory controller and qualified-vendor list determine whether 2666MHz is sustained or downclocked; the DIMM itself is certified for that speed on Supermicro platforms.
