Additional Notes
- The dual channel architecture implies that memory modules must be installed in identical pairs to achieve the peak theoretical bandwidth necessary for heavy gaming workloads.
- Hardware limitations prevent the use of higher frequency DDR5 modules due to physical pin configuration and voltage differences inherent to the 3200 MHz DDR4 standard.
- Upgrading the MSI GL66 12UGK-288BE Pulse to the 64 GB limit requires the removal of all existing factory modules since no additional vacant slots are available for expansion.
- Latency performance depends on matching the Column Address Strobe latency across both SO DIMM slots to prevent the system from downclocking to the slowest installed module.
- Thermal headroom within the chassis dictates the use of standard 1.2V sticks to avoid heat accumulation that could trigger aggressive CPU throttling during concurrent memory and GPU stress.
- Installation of high density modules requires a 64 bit operating system to address and utilize the full memory capacity beyond 4 GB.
