Additional Notes
- Dual-channel memory architecture requires matching modules in both slots to maximize memory controller bandwidth.
- Internal motherboard layout necessitates the removal of the chassis base plate and potentially the cooling solution for component access.
- Bios firmware limits memory frequency to 2400 MHz even if higher clocked 2666 MHz or 3200 MHz modules are installed.
- The 32 GB threshold represents the maximum addressable density supported by the HM175 chipset architecture.
- Installation of non-ECC unbuffered modules is mandatory as the system lacks support for registered or error-correcting memory types.
- Higher density 16 GB modules must be double-sided to ensure compatibility with the existing memory controller rank requirements.
- Voltage requirements are fixed at 1.2V meaning low voltage DDR4L variants are necessary for operational stability.
- Mixing different CAS latencies across the 2 slots forces the system to default to the timing parameters of the slowest module.
- Physical space within the slim V Nitro chassis prevents the use of modules equipped with tall heat spreaders.
