4GB DDR3 1333 desktop module

This 4GB DDR3 module runs at 1333MHz with CL9 latency and fits 240-pin DIMM slots. It is built for older desktop platforms that still use DDR3 memory. The non-ECC unbuffered design suits standard consumer motherboards rather than server boards. Buyers needing ECC support or higher capacities must choose different modules.

Dell OptiPlex 390 compatibility

The supplier data highlights compatibility with the Dell OptiPlex 390 desktop, indicating the module meets that system's memory requirements. No extra software or accessories are bundled with the stick itself. The listing simply confirms the part works in that specific chassis without additional configuration. Systems requiring registered or load-reduced DIMMs will not accept this module.

240-pin unbuffered construction

The stick uses a standard 240-pin DDR3 PCB with gold edge contacts for reliable slot insertion. Unbuffered construction keeps electrical loading low for typical consumer chipsets. The CL9 timing is fixed at the rated 1333MHz speed. Builders working with proprietary OEM boards that demand specific SPD profiles should verify the profile matches before purchase.

Questions sur cet article

Does the M378B5273CH0-CH9 module need any periodic cleaning or component replacement?

No routine maintenance is required for the M378B5273CH0-CH9. The DDR3 module has no moving parts or user-serviceable components; if a fault develops the entire stick is replaced.

What limit appears first when the M378B5273CH0-CH9 runs at full 1333 MHz continuously?

The first limit is the fixed DDR3 1333 data rate and CL9 latency; sustained throughput cannot exceed the PC3-10600 specification regardless of workload duration.

How much heat and power does the M378B5273CH0-CH9 produce during all-day operation?

The non-ECC unbuffered DDR3 module draws only standard 1.5 V power and generates minimal heat; no active cooling is needed beyond normal case airflow.
