Notes: 1. UPI/memory speeds are dependent on the processors installed in your sys-
tem. The X11DAC supports Intel C621. 2. Support for 2933MHz memory is dependent
on the CPU SKU. 3. Populating DDR4 memory modules in a two-DIMMs per-channel
(2DPC) configuration on this motherboard will affect memory bandwidth and perfor-
mance.
