I looked at the AGP \ PCI lock version, without those your not going to be able to OC very far anyway. Having a quick look I didnt see any CPU vcore options, but I did unlock a shitstorm of stuff, including an options for G.lan which your board seemingly has looking at its specs, but the option in the BIOS was locked out

Its not like your G.lan is crap either, supports up to 1000MB\s.
So in total here is what I did unlock
Load failsafe defaults (yes this was hidden.. go figure)
Various voltage monitoring stats (+3.3v, vbat etc)
CPU shutdown temp (yep you can now adjust this)
Fan3 speed (unsure if this is a monitor option or something that allows fan speed control.. eitherway its there)
PCI\VGA palette snoop
Vlink data rate (default 4x, 8x also selectable)
MTRR mapping
CPU cache options
Thers a load of other stuff too, but thats all I can remember off the top of my head.
