ASUS has used a modified version of the Award BIOS 6.0. The menu system is identical to the last series of boards that ASUS put out, so ASUS users will know how this works. ASUS puts all of the overclocking features under the one submenu, you need to navigate to the top advanced menu and select the Jumperfree submenu. Here are all of the settings you will need.
ASUS provides its automatic overclocking profiles on the A8R32-MVP Deluxe. You need to select Manual from the A.I Overclocking menu before the additional overclocking options will become available.
First on the list are the two major frequency options, the first is the Clock Frequency and the second is the PCI-E Clock option. You can adjust the clock frequencies in 1MHz increments. CPU clock can be adjusted from 200MHz up to 400MHz, with the PCI-E clock range from 100MHz to 150MHz. ATI has stated that with the latest RD580 chipset, PCI Express overclocks are possible, however, we had some issues with this - most likely because we used two graphics cards.
After this we get into voltages and the FID settings. AMD Athlon 64 allows you to reduce your CPU multiplier from its default down to as low as 4x. ASUS gives a range of multipliers from 4x up to 25x. However, if you set a multiplier above your CPU's default multiplier, the option is invalid and the CPU boots at its default multiplier.
Voltages come next. DRAM voltage is first on the list. ASUS provides a good range of setting from 2.5v up to 3.2v in 0.1v increments. This is a great range of options for even the most demanding memory modules.
Processor voltage is something that could do with a bit of a re-working. You can adjust the initial voltage from 0.0825v up to 1.45v. In order to get higher you need to enable the CPU Overvoltage option. This gives you +100mV and +200mV. This gives you an overall maximum of 1.65v on the CPU voltage. We would like to see this increased up to a max of 1.8v.
With all these setting we managed to get our 4200+ CPU to a max of 354MHz FSB with CPU voltage maxed out at 1.65v, DDR running 3.0v and the Northbridge overvoltage disabled. We are hoping to see some tweaks to the BIOS to allow faster speeds out of this setup.
