Memory Interleaving

Use this feature to set the DIMM memory interleaving mood. The options are NUMA

(1-way) Node Interleave, 2-way Node Interleave, 4-way Interleave, 8 Way Interleav-

ing, Inter-socket, and Auto.

Socket Interleave Below 4GB

Select Enabled for the memory above the 4G Address space to be split between

two sockets. The options are Enable and Disable.

Channel Interleaving

Use this feature to set the DIMM channel interleaving mood. The options are Auto,

1 Way Interleave, 2 Way Interleave, 3, Way Interleave, and 4 Way Interleave.

Rank Interleaving

Use this feature to select a rank memory interleaving method. The options are Auto,

1 Way, 2 Way, 4, Way, and 8 Way.

DRAM Maintenance

Select Auto for the BIOS to automatically congure DRAM Refreshing and Patrol

settings. The options are Manual and Auto.

pTRR (Pseudo Target Row Refresh) Support

Select Enabled for Pseudo TRR support which will allow the BIOS to assign an

invalid address to a questionable memory module to prevent this memory module

from being accessed by other components. The options are Enabled and Disabled.

Injection Probability

AMEI (Asynchroous MCA Error Injection) (AMEI) is a error-handling mechanism

that allows the BIOS to report the MCA errors to the CPU core or the CPU before

resuming normal operations. This item is used to set the threshold of the AMEI

events beyond which the BIOS will report the error events before resuming opera-

tions. The options are 512, 1024, 1365, 1638, 1820, 1928, 2048, 2731, 3277,

3641, 4096, 5461, 6554, 8192, 10923, 16384, 32768.

Demand Scrub

Demand Scrubbing is a process that allows the CPU to correct correctable memory

errors found on a memory module. When the CPU or I/O issues a demand-read

command, and the read data from memory turns out to be a correctable error, the

error is corrected and sent to the requestor (the original source). Memory is updated

as well. Select Enable to use Demand Scrubbing for ECC memory correction. The

options are Enable and Disable.
