Looking at the Gigabyte website you need to manually overclock the cpu to 2.66ghz.

how. i have tried but no joy

Increase the FSB to 333mhz and check the memory speed, as the multiplier / divider for the memory may need to be changed, hopefully save and exit.

Looks like you need to change the memory multiplier to allow your memory to run at 667mhz.

Also check page 48 in the manual regards 1333mhz cpu's.

O.C FSB1333 Core 2 CPU
Enable use of a CoreTM 2 CPU with 1333 MHz FSB through overclocking. You must install the
FSB 1333 MHz CoreTM 2 CPU with DDR2 533 (or above) memory module(s).
Auto Set this item to Auto. Then save the changes and restart your computer.
During the POST, a message will appear asking if you want to enable the use
of a FSB 1333 CoreTM 2 processor. Press <Y> to confirm or <N> to reject. Or
press any key to continue the POST. (Default value)
Disabled Disable this function.
Enabled Enable this function

EDIT: Enable FSB 1333 core.2 cpu.
