OEM MSI board locked?

[zxzxzx]

Hey, I haven't been around for a while but I got a new motherboard and I would like to overclock via the BIOS. It is an MSI 7036 board:

That's the link to the BIOS ver. 31. I don't know whether it is locked or not but when I go into the page for 'voltage/fequency control' the option for cpu overclocking is greyed out but I can change memory and pcie voltage. I am trying to overclock using a Pentium 4 3.2Ghz.

Sorry, i edited because i had the wrong link. It is now correct and the bios revision is 22.
