DRAM Remapping Above 4G Ensure your operating system is 64bit, when set to [Enabled], the feature allows your system identify more the 4GB memory. Flex M emory mode Flex memory mode provides the most flexible performance characteristics. The bottommost DRAM memory (the memory that is lowest within the system memory map) is mapped to dual channel operation; the topmost DRAM memory (the memory that is nearest to the 8 GB address space limit), if any, is mapped to single channel operation. Flex mode results in multiple zones of dual and single channel operation across the whole of DRAM memory. To enable flex memory mode, it is necessary to populate both channels. Configuration DRAM Timing by SPD Setting to [Enabled] enables DRAM CAS# Latency automatically to be determined by BIOS based on the configurations on the SPD (Serial Presence Detect) EEPROM on the DRAM module. TCL W hen the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. This controls the CAS latency, which determines the timing delay (in clock cycles) before SDRAM starts a read command after receiving it. Smaller clocks increase system performance while bigger clocks provide more stable system performance. TRAS W hen the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. This setting determines the time RAS takes to read from and write to a memory cell. TRCD W hen the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. W hen DRAM is refreshed, both rows and columns are addressed separately. This setup item allows you to determine the timing of the transition from RAS (row address strobe) to CAS (column address strobe). TRP W hen the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. This setting controls the number of cycles for Row Address Strobe (RAS) to be allowed to precharge. If insufficient time is allowed for the RAS to accumulate its charge before DRAM refresh, refresh may be incomplete and DRAM may fail to retain data. This item applies only when synchronous DRAM is installed in the system. 3-12 BIOS Setup South Bridge Press <Enter> to enter the sub-menu. Onboard LAN Controller This item is used to enable/disable the onboard LAN controller. Azalia HD Audio This setting is used to enable/disable the onboard audio controller. High Precision Timer The HPET (High Precision Event Timers) is a component that is part of the chipset. [. . . ] Press the "S" key to select "Specify Additional Device". You should be prompted to insert a floppy disk containing the JMicron RAID driver into the A: drive. Note: For W indows Vista you can use Floppy, CD/DVD or USB. Important Please follow the instruction below to make an "JMicron RAID Driver" for yourself. Copy all the contents in the \\IDE\JMicron\Floppy32 (for 32-bit OS) or \\IDE\JMicron\Floppy64 (for 64-bit OS) to a formatted floppy disk. [. . . ]
