A-Tech Supermicro Certified 8GB DDR4 2133 CL15

This 8GB DDR4 module is validated for Supermicro systems using the MEM-DR480L-SL01-UN21 part number. It runs at 2133MHz with CL15 latency and 1.20V standard voltage. The single-rank 1Rx8 Samsung chipset ensures stable operation in compatible desktop platforms.

Samsung M378A1K43BB1-CPB chipset

The Samsung M378A1K43BB1-CPB components are tested to Supermicro specifications for the MEM-DR480L-SL01-UN21 qualification. This certification changes the reliability baseline compared to generic modules. Each stick passes quality assurance testing before shipment to verify dependable performance.

288-pin DIMM installation requires motherboard

Install the unbuffered non-ECC DIMM into a DDR4 slot after confirming your system supports PC4-17000 speed and 1.2V operation. The most common issue is purchasing without verifying the motherboard qualified-vendor list for this exact part number. No heat spreader is present so clearance is minimal.

Questions about this item

Will the Samsung M378A1K43BB1-CPB chips on this module need replacement during the system's life?

The Samsung chips are factory tested and the module carries a lifetime warranty, so no scheduled chip replacement is expected under normal desktop use.

What limit appears first when this 2133 MHz CL15 DIMM runs sustained workloads?

The JEDEC 2133 MT/s data rate and CL15 latency set the throughput ceiling before voltage or thermal limits become a factor.

How much heat and power does the 1.2 V unbuffered DIMM produce during all-day operation?

At the standard 1.2 V DDR4 voltage and without a heat spreader, the module runs cool and draws minimal power typical for 8 GB Non-ECC desktop memory.
