Notes

12 DIMMs per processor, for a total of 48 DIMMs when four processors are installed. Each processor has 6 memory channels -- 2 DIMMs per channel (2DPC). The mixing of x4 and x8 RDIMMs is supported, and the mixing of RDIMMs of different capacity is supported. However, Chipkill works only in the independent channel mode (the default operational mode) and supports only x4-based memory DIMMs. Do not mix R-DIMMs, 3DS R-DIMMs and LR-DIMMs. Actual memory speed is determined by the specific processor model installed.
