8GB DDR4 2133MHz Desktop Module

This A-Tech module is an 8GB DDR4 2133MHz DIMM built with Micron components and validated as Supermicro Certified MEM-DR480L-CL02-UN21. It runs at 1.20V with CL15 latency in a 2Rx8 unbuffered layout. The 288-pin form factor fits standard desktop DIMM slots.

Suits Supermicro Systems Only

Choose this kit when your Supermicro documentation lists MEM-DR480L-CL02-UN21 as supported memory. It is not intended for platforms that require ECC or registered modules. Buyers needing error correction or server-qualified registered DIMMs should select a different part.

Certified Supermicro Part Number Decides Fit

The single specification that determines compatibility is the Supermicro part number MEM-DR480L-CL02-UN21. Verify this exact identifier against your system's qualified vendor list before purchase. No other speed, voltage or capacity variation substitutes for this certification.

Questions about this item

Do I need a motherboard with DDR4 288-pin DIMM slots to install this module?

Yes, this 8GB stick uses the DDR4 288-pin DIMM form factor and requires a desktop motherboard with matching DDR4 slots.

Can I mix this 2133MHz CL15 1.2V module with older DDR4 sticks that run at different speeds or timings?

The system will downclock all modules to the lowest common speed and loosest timings; matching voltage at 1.2V helps stability but identical specs give best results.

How can I verify the RAM is running at the rated 2133MHz after installation?

Check the memory frequency in BIOS/UEFI or use a tool like CPU-Z; it should show 2133MHz (PC4-17000) with CL15 timings at 1.2V.
