Overclocking with the Gigabyte DS3

[manveruppd]

Got some short Qs re: the BIOS options in this baby!

In the "MB Intelligent Tweaker Menu":

- "CIA2" and "Performance Enhance" - I assume these are some crappy automatic memory-timing tightenning features that are best left alone when overclocking?

- "System Memory Multiplier" - I'm guessing this is the FSB ratio, which at the moment is set to 667:867, but I don't understand what the explanatory rolleyes: ) text on the right pane means when it says:

+ --> 800 strapping
~ --> 1066 strapping
# --> 1333 strapping

I know the numbers are DRAM speeds in MHz, but each of those numbers is achievable under +, ~ or # using the different options available under this menu! So basically there's 3 different "flavours" for each ratio selection, and I don't understand what each of them is for!

- Finally, "(G)MCH OverVoltage Control" - is this chipset voltage?

Ah, nice, thanks Cob, pretty much as I guessed then! That's not what I found with the FSB ratio though - I can see all of the options to choose from, and for each ratio there's one each of +, ~ and #! My chips are DDR2 666 by default, but they're Ballistix which people have clocked up to 1066.
Could you not be seeing the other signs because you're on a different BIOS revision? I'm using F11.

Oh, no, you're right, I just checked again and I was talking out of my rectum, it's just x4 that has three options. I bet I COULD manage x4 though, since my memory is only 667MHz, so which of the three should I go for?
(not that there's much point because apparently the C2D's FSB gets choked on anything more than 800MHz, but I might do it out of curiosity, or for the kudos and the infinitessimally better benchmark scores)
