Bank Interleaving
Bank Interleaving is an advanced chipset technique used to improve memory
performance. Memory interleaving increases bandwid th by allowing s imultaneo us
access to more than one piece of memory.
Options: Auto (Default)
Channel Interl eaving
This item allows you to control the DDR2 dual-channel function.
Options: Auto (Default) / XOR of Address bit
Enable Clock to All DIMMs
This item determines whether the BIOS should actively reduce EMI
(Electromagnetic Interference) and reduce power consumption by turning off
unocc up ied or inactive DIMM s lots.
Options: Disabled (Default) / Enabled
MemClk Tristate C3/ATLVID
This item enables or disables the MemClk Tristate function in C3 Mode.
Options: Disabled (Default) / Enabled
Memory Hole Remapping
This item allows you to enable or disable the remapping of the overlapped PCI
memory above the total physical memory. Only 64-bit OS supports this function.
Options: Enabled (Default) / Disabled
