Recommended Memory Population Table
Single CPU Installed
Quantity of memory installed 1 2 3 4
DIMM1 √ √ √
DIMM2 √ √ √ √
DIMM3 √
DIMM4 √ √
NOTE:
1. √ indicates a populated DIMM slot.
2. Paired memory installation for Max performance.
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. Un-buffered DIMM can offer slightly better performance than registerd DIMM if
only a single DIMM per channel populated
6. We don't suggest other memory installation.
