► Memory Configuration
Press <Enter> to go to its submenu.
The following six items display the DRAM timing values.
► CAS Latency
This item shows the CAS latency. The CAS Latency is the number of clock cycles that elapse
from the time the request for data is sent to the actual memory location until the data is
transmitted from the module.
► RAS / CAS Delay
This item displays a delay time (in clock cycles) between the CAS and RAS strobe
signals.
► Row Precharge Time
This item shows the number of clock cycles taken between issuing of the precharge command
and the active command. The DRAM row precharge time is in unit of clock cycle.
► Min Active RAS
Displays the number of clock cycles taken between a bank active command and
issuing of the precharge command.
► RAS / RAS Delay
This item shows a delay time (in clock cycles) between the RAS and RAS strobe
signals.
► Row Cycle
This item displays the minimum timing interval between successive active commands to the
same bank. The row cycle time is in unit of clock cycle.
► Internal Graphics Mode
Enable/Disable the integrated UMA graphics controller.
► UMA Frame Buffer Size
Allocates system memory for use as video memory to ensure the most efficient use of
available resources for maximum 2D/3D graphics performance.
This is a memory allocation method addition to the Unified Memory Architecture (UMA)
