Precharge Time

This controls the idle clocks after issuing a precharge command to the SDRAM. NOTE: To make changes to this field, the Configure SDRAM Timing by SPD field must be set to [Disabled]. Available options: [3 Cycles] [2 Cycles] [1 Cycle]

RAS Active Time

This specifies the minimum bank active time. NOTE: To make changes to this field, the Configure SDRAM Timing by SPD field must be set to [Disabled]. Available options: [2 Cycles] [3 Cycles] [4 Cycles] [5 Cycles] [6 Cycles] [7 Cycles]

CAS Latency

This controls the latency between the SDRAM read command and the time that the data actually becomes available. NOTE: To make changes to this field, the Configure SDRAM Timing by SPD field must be set to [Disabled]. Available options: [3 Cycles] [2 Cycles] [4 Cycles]

RAS-to-CAS Delay

This controls the latency between the SDRAM active command and the read/write command. NOTE: To make changes to this field, the Configure SDRAM Timing by SPD field must be set to [Disabled]. Available options: [1 Cycle] [2 Cycles] [3 Cycles] [4 Cycles]

DRAM Integrity Mode [Disabled]

[ECC] with hardware scrubbing allows the detection of single-bit and multiple-bit errors and recovery of single-bit errors. This field is available only if your DIMMs have ECC. Available options: [Disabled] [ECC]

DRAM Burst Refresh [Enabled]

This controls the queuing of refresh requests. When [Enabled], up to four refresh requests are queued before being sent to the memory controller. When [Disabled], refresh requests are only queued if memory requests are currently being serviced.

Graphics Aperture Size [64MB]

This feature allows you to select the size of mapped memory for AGP graphic data. Available options: [32MB] [64MB] [128MB] [256MB] [512MB] [1GB]

Memory Hole [Disabled]

This allows you to specify the memory address space to be reserved for ISA expansion cards that specifically require this setting. Setting the address space to a particular setting will make that memory space unavailable to the system. Expansion cards can only access memory up to 16MB. Available options: [Disabled] [14MB- 15MB] [15MB-16MB] [14MB-16MB]
