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)
-
Refresh Cycle Time (tRFC)
Init Display First
This item allows you to choose the primary display card.
HDMI Port Display
This item selects the type of display device connected through the "HDMI Port" on this
motherboard.
[DVI]: Select this option if you are connecting a non-HDMI monitor through the "HDMI Port"
on this motherboard. This is the default setting.
[Normal]: Select this option if you are connecting HDMI digital display through the "HDMI
Port" on this motherboard.
An unmatched configuration will cause the display device abnormal. For example, an HDMI
digital device connected to "HDMI Port" under the [DVI] selection will have no sound on the
digital display, whereas a non-HDMI monitor connected to "HDMI Port" under the [Normal]
selection will cause the screen flickering. Select the correct one for your display device.
UMA Frame Buffer Size
This item selects the size of memory pre-allocated for frame buffer.
