The BIOS on the AS45GTR offers plenty to
satisfy even the hardcore overclocker. To your left, you have
your main menu. On the right, you have your Advanced chipset
features screen where we can configure our memory settings.

On your left you have your DRAM config
screen. We installed a stick of Corsair XMS 2700 and set the CAS
latency to 2 and set it to the highest performance. "Ultra Mode"
On the right we have our integrated
pheripherals menu where we can configure our onboard devices, etc.

On your
left screen we can Enable/Disable the RAID controller, Onboard Audio,
USB 2.0 support, etc. On the right we have additional hardware
settings for Serial/Parallel ports, Floppy, etc. Yes. We
disabled the FDC! No more floppies!!!

And last
but not least, our overclocking menu! :) First we have CPU
voltage which can be set from 1.1v to 1.825v in 0.025v increments.
Video card voltage can be can be adjusted as well. Memory
voltage can be set from 2.55v to 2.75v in 0.05v increments. CPU
FSB clock speed can be changed from 100 - 165FSB in 1MHz increments.
The CPU:DRAM clock ratio defines at what speed the system memory
operates at with respect to the CPU FSB clock. From 100-132 CPU
FSB, you can set the memory speed to either 1:1, 3:4, 3:5, or 1:2.
At 133-165FSB, your ratios change to accommodate the faster CPU FSB.
4:3, 1:1, 4:5, and 2:3 ratios.
Overclocking:
We were able to set the FSB up as
high as 150 as long as our CPU voltage was adjusted as well. We
set it at 1.65 and left the Video/Memory voltage at default. I
have not played with it much but I'm assuming I can go alittle higher
if I play with this menu a bit more. With this said, the
board is not intended for the hardcore overclocker. System
stability was rock solid at 133 FSB and remained stable up to 145 FSB.
