The Frequency/Voltage Control page has some changes, too. I doubt whether the change of the chipset was the reason. So, we now have an item called V-Link Voltage. I think the name speaks for itself, but the purpose of the option is unclear. Why would anyone increase the voltage of the bus connecting the chipset Bridges? Anyway:

The rest of the options are closer to the routine. We can change the bus frequency from 100MHz to 280MHz with 1MHz increment (the upper limit is of course inaccessible in practice). It’s nice we can type in the value from the keyboard rather than browse through a long list of possible values. Unfortunately, the BIOS doesn’t show what frequencies the AGP and the PCI bus will work under the given FSB clock-rate.

Then, we can adjust the CPU multiplier; the maximum one is only 15x. The Vcore can be adjusted from 1.375 to 2.3V. This is a wide range, since the nominal voltage of modern AMD processors doesn’t exceed 1.65V. Moreover, the BIOS offers a hint showing the nominal voltage for your processor. That’s good.

Then comes that V-Link Voltage option, ranging from 2.6V to 2.8V with 0.1V (or Auto) step. I don’t know whether it’s much or not, as I’m not at all sure how this value tells on the mainboard operation. Moreover, the nominal voltage is not clear, too. DDR Voltage can be set from 2.55V to 3.3V with 0.05V increment. You can set this option to Auto and hope for the mainboard to supply the nominal 2.5V voltage to the memory. I say “hope” because mainboard makers have been quite freakish as far as the automatically set voltage values are concerned. By the way, the available Vdimm range of the MSI KT6 Delta mainboard should be considered very wide.

The last is the Vagp, which is changeable from 1.55V to 2.1V with 0.05V increment. That’s impressive really. As for me, I would never dare to send 2.1V voltage to my own graphics card, but some people may find this useful. On the other hand, considering the popularity of the nForce2 chipset among overclockers, the prospects of the MSI KT6 Delta among this public look obscure. Still, we have to see the mainboard in action yet.

Winding up with the voltages, I’d like to mention two peculiar things about the BIOS. First, the mainboard sets too high voltages for V-Link (2.7V – although the nominal is unknown, it is not more than 2.6V), for the memory (2.7V against 2.5V nominal) and AGP (1.7V instead of 1.5V). The mainboard is quite stable at the nominal voltages, though. Maybe this way MSI just wanted to make sure that no stability problems ever occur.
