BIOS Setup

The BIOS of Asus M4A78T-E mainboard differs really slightly from the BIOS’s of other Asus mainboards we have reviewed before. So, it is going to be really easy to find your way through all these options and settings.

“Ai Tweaker” section that contains almost all the overclocking-related settings, by default doesn’t require the user’s attention: all parameters will be set automatically.

However, you can really appreciate the convenience of this section when you get to change some of the settings. All frequencies are reported as they actually are and they will change depending on the changes in the clock generator frequency. Only the actual values will be reported. The dangerously high values will be highlighted purple and then red.

The maximum processor Vcore can be set at 1.45V. If you want to be able to raise the CPU core voltage up to 1.65V, you need to reset the “CPU overvoltage” jumper on the board. This is more than enough to successfully overclock the CPU with traditional air cooling. However, if you plan on using more extreme cooling methods, you may need more than that.

The memory controller settings are singled out into a separate sub-section called “DRAM Controller configuration”.

The numerous parameters related to memory timings are also summed up in a separate sub-section.
