Additional Notes
- Dual channel architecture requires matching memory modules to reach peak data throughput and bridge the processor bandwidth gaps.
- The HP EliteBook 645 G9 utilizes a standard SODIMM interface which allows for tool based maintenance without proprietary hardware locks.
- Installing 32 GB modules in each of the 2 slots is necessary to reach the platform maximum of 64 GB.
- Memory modules exceeding the 3200 MHz frequency will downclock automatically due to motherboard chipset limitations.
- Physical installation of RAM does not void the standard hardware warranty if the internal components remain undamaged during the process.
- Total system latency is governed by the slower of the 2 installed modules if timings are not identical.
- Upgrading from a single module to a dual module configuration significantly improves integrated graphics performance by doubling the available memory bus width.
