The BIOS that powers the MSI 845Pro2-R
is pretty overclocking and tweak friendly. With a fair amount of adjustments for memory, voltage and clock speeds it gives you a good set of tools to make custom adjustments.
Processor Adjustments are standard; CPU clock adjustments range from x8 - x24 and CPU FSB can dialed in
upto 132MHz in 1MHz intervals.
AGP/PCI Clock can be adjusted if you so desire or simply left to auto configuration.
Both VDIMM and Vagp (AGP Voltage) can be
tweaked in 0.05 volt increments, while CPU Vcore (Voltage to the Core) can be tweaked on 0.025V increments.
The Award BIOS also allows some modest adjustments
to be made to the SDRAM. CAS latency can clipped to 2 if you've chosen to
configure your own settings and override the SPD data. RAS-to-CAS, and RAS
Precharge also follow suit in the 2, or 3 settings department.
