Capacity and compatibility
This 8GB DDR4 module replaces the Samsung M378A1G43EB1-CPBD0 in desktop systems. It runs at 2133MHz with a CAS latency of 15 and operates at the standard 1.2V. The unbuffered, non-ECC design fits 288-pin DIMM slots for straightforward upgrades.
Sustained workload behaviour
Under continuous load the memory maintains its rated 2133MHz frequency and CL15 timing without throttling. The Samsung chipset and 1.2V operation keep power draw stable during extended multitasking or rendering sessions. Quality assurance testing confirms reliable performance over long periods.
Installation notes
Align the notch on the 288-pin module with the motherboard slot and press until the retention clips click. No heat spreader is present, so clearance is rarely an issue. The most common problem is mixing this stick with modules of different speeds or latencies, which can prevent the system from posting.

Questions sur cet article
How hot or noisy does the 1.20V DDR4 module get when the system runs all day?
The module operates at the standard 1.20V DDR4 voltage without a heat spreader, so it runs cool and silently inside a normally ventilated desktop case.
What must my motherboard already provide for this 288-pin DDR4 DIMM to work?
Your board needs a free DDR4 DIMM slot that accepts 288-pin unbuffered non-ECC memory at 1.20V and supports 2133 MT/s operation.
Will this 2133MHz CL15 stick run stably alongside the older 2133MHz modules I already have installed?
Yes — matching speed, voltage and CAS latency lets the new 8GB module run in step with existing 2133MHz CL15 DDR4 DIMMs without down-clocking.
