— 64GB TSV-RDIMMs cannot be mixed with any other DIMMs
— You cannot mix RDIMMs with LRDIMMs
■
To optimize memory performance:
— Configure DIMMs identically for each CPU
— Fill banks equally across the CPU. See DIMM population guidelines in Table 27 on
page 41 , Table 28 on page 42 , and Table 29 on page 42 .
— Populate less than 3 DPC
