Abit NF7 Row-active delay, RAS-to-CAS delay, Row-precharge delay, CAS Latency Time, LDT Voltage

BIOS Setup 3-5

Row-active delay:

Fifteen options are available: from 1 to 15. This option specifies the row active time. This is the minimum number of cycles between an activate command and a precharge command to the same bank.

RAS-to-CAS delay:

Seven options are available: from 1 to 7. This item is to set SDR/DDR SDRAM RAS to CAS delay. It can define the SDRAM ACT to Read/Write command period.

Row-precharge delay:

Seven options are available: from 1 to 7. This item controls the idle clocks after issuing a precharge command to the DRAM.

CAS Latency Time:

Three options are available: 2.0 ￿ 2.5 ￿ 3.0. The default setting is 2.5. You can select SDRAM CAS (Column Address Strobe) latency time according your SDRAM specification.

Power Supply Controller:

This option allows you to switch between the default and user-defined voltages. Leave this setting to default unless the current voltage setting cannot be detected or is not correct. The option “User Define” enables you to select the following voltages manually.

CPU Core Voltage:

This item selects the CPU core voltage.

DDR SDRAM Voltage:

This item selects the voltage for DRAM slot.

LDT Voltage:

This item selects the LDT voltage.

AGP Voltage:

This item selects the voltage for AGP slot.

ATTENTION: A wrong voltage setting may cause the system unstable or even damage the CPU. Please leave it to default settings unless you are fully aware of its consequences.
