Nvidia 680i manual FSB and Memory Clock Mode, Linked, Unlinked, FSB QDR, MHz, MEM DDR, MHz

Configuring the BIOS

When you select one of the CPUOC x% options, the FSB - Memory Clock Mode is set to Unlinked and cannot be changed until SLI-Ready Memory is set to Disable.

•FSB and Memory Clock Mode

Use the Page Up and Page Down keys to scroll through the FSB and Memory Clock Mode options. The options are:

➢Auto

This is the optimal setting since it sets the FSB and memory speeds automatically.

➢Linked

When Link is selected, FSB (QDR), MHz is changed to editable and the FSB speed can be entered manually. As the FSB speed is changed, CPU Freq, MHz changes proportionally.

➢Unlinked

When Unlink is selected, FSB (QDR), MHz and MEM (DDR), MHz are changed to editable and the FSB and memory speeds can be entered manually. As the FSB speed is changed, CPU Freq, MHz changes proportionally.

•FSB (QDR), MHz

Use the + or – keys to scroll through new values for the CPU FSB frequency or type in a new value. Note that the Actual FSB (QDR) reflects the actual frequency that takes effect on a reboot.

•MEM (DDR), MHz

Use the + or – keys to scroll through new values for the memory frequency or type in a new value. Note that the Actual MEM (DDR) reflects the actual frequency that takes effect when the system reboots.
