Interleave NVDIMMs
If this item is set to Enable, all onboard NVDIMM modules will be configured together as
a group for the interleave mode. If this item is set to Disable, individual NVDIMM modules
will be configured separately for the interleave mode. The options are Enable and Disable.
Reset Trigger ADR (Async DIMM Self-Refresh)
Upon system power loss, an ADR sequence will be triggered to allow ADR to flush the
write-protected data buffers in the memory controller and place the DRAM memory in self-
refresh mode. When this process is complete, the NVDIMM will then take control of the
DRAM memory and transfer the contents to the onboard Flash memory. After the transfer is
complete, the NVDIMM goes into a zero-power state. The data transferred will be retained
for the duration specified by the flash memory. The options are Enable and Disable.

Select Enabled to support S5-Triggered ADR to enhance system performance and data
integrity. The options are Disabled and Enabled.
