Capacity and Compatibility
This 8GB DDR4 module runs at 2133MHz with CL15 latency and 1.2V operation. It is built as a compatible replacement for the Samsung M378A1K43BB1-CPBD0 part number. The unbuffered, non-ECC DIMM targets desktop users who need a direct swap for that specific Samsung stick.
Form Factor and Testing
The stick uses a standard 288-pin DDR4 DIMM layout, noted as 262-pin in the supplier data, and carries Samsung chipset components. No heat spreader is fitted, keeping the profile low for tight slots. Every unit passes A-Tech quality assurance testing before it ships.
Installation and Common Issues
Installation follows the usual desktop DIMM procedure: align the notch, press until the latches click, and verify the system POSTs at 2133MHz. The most frequent issue is a motherboard that defaults to a lower speed or fails to train when the slot population changes. Checking the manual for supported frequencies and seating the module firmly resolves most problems.

คำถามเกี่ยวกับสินค้านี้
Will the module ever need a heat spreader added later?
No heat spreader is fitted and the 1.20V DDR4 design runs within JEDEC thermal limits, so no aftermarket cooling is required.
What caps sustained throughput first — the CL15 latency or the 2133 MT/s bus?
The 2133 MT/s data rate is the hard ceiling; CL15 only adds a few nanoseconds per access and does not limit peak bandwidth.
How much power does an 8 GB stick draw when the system runs all day?
At 1.20V the module typically draws 2–3 watts, producing minimal heat and negligible fan noise inside a desktop chassis.
