Supermicro Certified 8GB DDR4 Module

This module is a Supermicro certified MEM-DR480L-CL01-UN21 DIMM built with Micron chips. It delivers 8GB of DDR4 memory at 2133MHz with a CL15 latency and 1.2V operation. The 288-pin unbuffered non-ECC design targets compatible Supermicro desktop systems.

Sustained Load Behaviour

Operating at the standard 1.20V DDR4 voltage, the module maintains its 2133MHz frequency and CL15 timing during extended workloads. The unbuffered architecture provides direct memory access without registered delays. Micron chipset construction supports consistent data integrity across long sessions.

Installation Notes

The 288-pin DIMM form factor fits standard DDR4 desktop slots with a single keyed orientation. No heat spreader is present, so the module sits low in tight layouts. Verify your system supports PC4-17000 DDR4 2133 non-ECC memory before purchasing.

Questions about this item

How much power does the 1.20V DDR4 2133MHz module draw during continuous use?

It operates at the standard 1.20V DDR4 voltage, which keeps power draw low and heat output minimal during all-day workloads.

What motherboard slot is required for this 288-pin DIMM?

A desktop board with a standard DDR4 288-pin DIMM slot is needed; the module is unbuffered and non-ECC.

Will this CL15 2133MHz stick run with older DDR4 modules at lower speeds?

Yes, the memory will down-clock to match the slowest installed module while maintaining 1.20V operation.
