1.
¥
indicates a populated DIMM slot.
2. Install memory in sets of fours for maximum performance. This ensures that all four
memory channels are properly utilized, providing maximum memory bandwidth.
3. Populate the same DIMM type in each channel, specifically
- Use the same DIMM size
- Use the same # of ranks per DIMM
4. Dual-rank DIMMs are recommended over single-rank DIMMs.
5. Unbuffered DIMMs can offer slightly better performance than Registered DIMMs if
populating only a single DIMM per channel.
6. Always install with DIMM_A0 Slot first, following the alphabetical order (starting with
DIMM_A0, DIMM_B0, DIMM_C0, DIMM_D0), and then the numerical order (starting
with DIMM_A1, DIMM_B1, DIMM_C1, DIMM_D1, DIMM_A2, DIMM_B2, DIMM_C2,
DIMM_D2).
