LGA775 pinmods: help needed

Hi there, guys. I'm in need of help with LGA775 pinmods, there are some things I'd like to know before I mess something up.

The first one has to do with "VCC" and "VTT" mods. I've read here there are two ways of making the mods, the "regular" VCC mod, which is not recognized by some boards (like Gigabyte ones); and the VTT mod, using a VTT pin instead of a VCC one. Does someone know if the VTT mods can "fool" the boards that don't recognize the VCC mod? It would be a very nice way to bo around the lack of 1:1 divisor on the G33M-DS2R... And, speaking of boards that don't recognize BSEL mods, do you think an ASRock (ConRoe945G-DVI) would recognize the mod?

Second question: these pinmods are directed at CPUs, not the motherboards. What I'd like to know is if somehow I managed to mod the LGA socket itself (to make 800MHz CPUs become 1066MHz ones, for instance), what would be the reaction of a 1066MHz CPU being put there instead of the 800MHz one? Nuclear catastrophe?

Third question: I have an 945GZ-based mobo mounting an 805. As you all know, 945GZ chipsets are limited to 800MHz CPUs, and have the same yucky PCI-E lock (a.k.a., non existant... lol). I'd like to overclock that 805. I was thinking about going to 666MHz (166MHz Quad-pumped), but I've read here about a guy who had problems with the PCI and AGP locks which resulted in data corruption. Also, do you think going all the way up to 800MHz would need the vMod too? What kind of temps should I expect, considering I'm now in the low 30s - ºC, mind you - when idling, and around 50ºC on load?

Ok, last ones: is there a soul kind enough to make a list of BSEL and Voltage mods for LGA775 CPUs? With every permutation, like 533 to 667 to 800 to1066? It is an enormous pain to find that sort of stuff...

Thanks in advance for the help. I only hope I'm posting in the right sub-forum... :shrug:

Cheers.
