[No]: The system always send clock signal to all PCI slots.
※
Set this option to [No] setting if there are adapters that cannot be
automatically detected by the system and will cause malfunction.

DRAM Timing Selectable
This item sets the optimal timings for the following four items, depending on the memory
module you are using. The default setting "By SPD" configures these four items by reading the
contents in the SPD (Serial Presence Detect) device. The EEPROM on the memory module
stores critical parameter information about the module, such as memory type, size, speed,
voltage interface, and module banks. The following items will be available to make adjustments
by selecting option [Manual].
- CAS Latency Time (tCL)
- RAS# to CAS# Delay (tRCD)
- RAS# Precharge (tRP)
- Precharge Delay (tRAS)
- Command Rate
- tRFC
