Vmod 3850 through BIOS apparently IS possible....

[os008]

does CCC - overdrive still work properly w/ this BIOS?

No, it's screwed up, that's why i used Rivatuner to get stable clock, then write it inside the BIOS and flash it and get rid of the hassle.

I don't get it, why not sharing the tool for modifying the bios...or make a how-to?

This creating of bioses to rigth and left is kinda silly, just give some hints on how to do it instead.

Silly? was i wrong to help someone? didn't get the idea of making a tutorial, not good at it, so i just posted the BIOS' for testing, not going to it again anyway, those are all there is to modify.

Anyway, it's not that hard, ... start HxDen, search for BE04 as Hex Value, press F3 to search again, and you'll find yourself at a distinctive pattern.

Let's say you want to change the voltage from 1.2 to 1.3 ... open up the windows Calculator, set it to Scientific, then Hex, then write 04BE, then press on Dec, should give you 1214, that's 1.214v, to get 1.327, then write 1327 in Dec mode, then switch to Hex, you'll get 52F, reverse it, so it's 2F05, now write that number instead of BE04, as easy as that.

For frequencies, you'll find 540501 on the same line of the voltage to the left, if you don't see 54, you'll find it just at the end of the line above it to the right, that's the number for 669 core frequency, reverse it ... 010554, and convert it ... 66900, that's 669.00MHz, write 76000 ... 128E0, reverse it ... E02801, write it in place of the frequency inside the file, again, as easy as that.

Just got it by experimentation, and bits of info from here and there, note that i don't know ANYTHING about how to calculate Hex values, or why do i have to reverse them, or why do i have to keep the middle number fixed ... etc, i just managed to get something going that i need, i don't care to understand how it works, as long as it works.

The second program is for comparing files in Hex mode, i use it a lot because sometimes i forget where the pattern is if i changed the voltage for example, all i have in my memory is BE04, so i open up the original BIOS, compare it to the one i changed, then search for that Hex, and i get where i want to be.

Hope it helped.


EDIT: Here's a link explaining the same thing, but in what seems to be Yoguslavian or something (guess so from the address).
