BIOS


The Main and Advanced screens do not contain many options that require user input, they are mostly informational only. One exception to this is the Northbridge Configuration found on the Advanced tab. This screen controls the onboard GPU settings, which we will get into more depth with later.


PCIPnP, Boot and Security settings are pretty self-explanatory. These options are typically found in nearly every motherboard BIOS in one form or another.


The JUSTw00t! screen is probably where you will spend most of your time if you are looking to overclock your system. Seems like a silly name for this particular tab however. The Power screen contains the Hardware Health monitor, which can be used to keep an eye on temperatures, voltages and fan settings.


Moving back to the JUSTw00t! screen, under the submenu for AMD Overclocking Configuration, we have options for changing the FID, VID, HT, DIMM and Reference clock, as well as an automated overclocking tool called A.I. On a locked processor, only the options for stock FID and VID and lower are available. The HT link speed is selectable up to 2600Mhz, however K8 CPU's run at only 1000Mhz by default.


The Memory Configuration screen has options such as specifying bank interleave and ganged/unganged mode. The CPU/HT reference clock is a user-entered value anywhere from stock 200Mhz up to 400Mhz. The A.I. overclock function has five settings from 210 up through 250Mhz which gives novice users up to a possible 25% overclock from stock.


The DRAM Timing configuration allows for memory settings from 200Mhz up through 533Mhz in speed. The timings can be manually adjusted for each individual setting if desired, or simply left on Auto to detect by SPD.


The voltage controls allow for a DIMM boost up to three tenths of a volt from default. The CPU voltage options are much less, only one tenth over stock for this chip. We would have a lot more headroom for overclocking our hardware if there were better options for voltage controls.

Speaking of overclocking, let's take a look at that next.
