The checksum is a 1 byte value, that is computed from the rest of the BIOS. Any little change to the BIOS, and this value will be different. When comparing the BIOS to the checksum, you can see whether there is a mistake in the BIOS (making the BIOS invalid). I have yet to experience anyone with issues caused by a wrong checksum, but correcting it can never hurt
. Try running "kgb 1.rom" before you fix the checksum, and watch the nice big error on your screen.
(also, use the "spoiler" when quoting such big a reply)
Great! Why aren't you using it now?
Well the max boost clock is already adjustable in KGB so need for HEX editing that. I am actually after the Boost Clock adjustment in Precision (which is the offset, in MHz, from the Boost Clock), do you know how to HEX edit that? Which values are difficult to compute?
Thanks for the explanation of checksum. AFAIK, when the checksum is wrong nvflash won't allow you to flash it to your card, right?
I really wanted to use spoiler when I was quoting your wall of text but I don't know how to do it?
Regarding the 3rd power target mentioned by error-id10t do you know about it? Also, in the guide you made how do you determine that the first set (highlighted in red) of HEX values are for the default power target and the second set (highlighted in blue) are for the max power target?

On the vBIOS that lilchronic posted, it's set to 250W and is more than likely the default for 670 FTW anyhow (I'd have to check but that's not important, the point was that even that value was more than he saw in power-usage and couldn't be restricting him).
So if you use the good guide iRandomize provided then you can find all 3 of these values near each other.
I still don't get. So there is a default power target, max power target, and what is the 3rd power target? In my stock vBIOS, my default power target is 200W, my max power target is 224W (112%), and what is my 3rd power target then?
Regarding lilchronic's vBIOS, what is the explanation why when his max power target is set to 150% he gets up to 137% power usage in FC3 but when he modifies his max power target to 200% he gets 141%? Or are those power fluctuations only?
