Additional Notes
- The presence of a single SO-DIMM slot on the MSI PS42 8RA-055 Modern prevents dual-channel memory configurations, limiting the system to single-channel bandwidth speeds.
- Increased latency occurs during memory-intensive tasks because the processor cannot access two memory modules simultaneously.
- Upgrading to the maximum supported capacity requires the complete removal and replacement of the existing module rather than adding a second stick.
- Integrated graphics performance will be restricted by the single-channel memory interface since the GPU shares the available system bandwidth.
- Installing a module with a frequency higher than 2400 MHz results in automatic downclocking to match the hardware-coded ceiling of the motherboard chipset.
- The motherboard architecture lacks soldered memory banks, which ensures that the entire system memory remains replaceable in the event of a module failure.
- The physical thinness of the chassis necessitates the use of standard voltage 1.2V modules to maintain thermal stability within a constrained internal environment.
