As for BIOS, the only way I know of to tell the difference between the 2C and 4C versions if if you can control your multi or not. The 2C gives multi control to non exteme processors in 521... the 4C to extreme processors. If you can control your multi, you have the right version for your CPU. AFAIK the 723 bios does not allow multi control on any processor. None of this matters if you are using your default multi though.
Hi Virtualrain, I read your guide for this motherboard and I really liked it, thank you for sharing so good information and for making many links .

I have an overclocking problem with the Q6600; if I use the 2CTST BIOS I'cant enter windows if I set 400Mhz FSB. I tried more the 40 and I say 40 different VTT - GTL settings, starting from VTT 1,60 200-115-95 and also settings like the one you suggested for 1600Mhz(VTT 1,60 195-195-95) and many more (also using lower values like VTT 1,40 and 170-95-85). I tried all the possibile settings I found and I also tried to make some new settings respecting the ruels for GTL values and also tring to do, as I said, something like your setting (with very close GTL1 and GTL2 settings). Nothing to do.

Then I tried the 4CTST BIOS (I also tried the last BIOS but I have many problems about VTT and LTD voltages, as I said befeore, so I am not using that BIOS) and I could enter Vista simply setting VTT 1,40 and 170-95-85. The problem is that I am not stable because the CPU Multi is fixed @ 9X (default).

So what I think (and I also opened a discussion in the DFI Club forums) is that the 2CTST BIOS is NOT good for Q6600 because it seems to be impossibile to enter in Windows with FSB400Mhz; and the 4CTST BIOS could be much better, because you can easly enter Windows, but it is difficult to find a Q6600 that can reach 3,6Ghz at voltages good for air or liquid cooling...

What do you think?
