Pencil mod a motherboard?

My motherboard (Asus a55bm-e)(fm2+) has no vcore control option in bios. What can I do to allow me to control the vcore? Can i mod the uefi bios? Or should I try to pencil mod my motherboard?

It only has 3+1 power phase but i want to push it to the limits, this motherboard is not meant to last long.

I've not really came across this pencil mod before, do they even have much effect?
Its a way of controlling voltage by hardware mods
It could go easily wrong, you can send 2v+ to your cpu :D

it was usually done with a bit older amd/nvidia (gtx 9800, gtx 250 etc.) cards that had no software voltage control and socket 775 motherboards (like asus p5e)

Yeah it seemed like all the Google results were from at least several years ago. It seems like an interesting thing to try, albeit quite a bodge job; it would be interesting to see if you got any benefit from doing it, but perhaps not worth the risk if it can easily go wrong :P
 
I will upload high res photos of the my motherboard including the EPU chip on here tomorrow, and maybe some expert on here is going to help me out

Is asus going to be nice enough to send me a modded bios? I would be pleasantly surprised if they did.

I'd be surprised too seeing as that ain't even a board for OC'ing and ASUS are pretty particular about people tinkering with there ROMs, you'll more than likely get the generic sorry but those files don't exist if you require overclocking features may we suggest up grading to blah blah blah..

Also pencil modding?? Really does anyone even bother any more it was seriously unreliable back in the late 80's early 90's, I know we tried once with a Athlon 7750BE by de-lidding it and tracking across 2 points this was copied from a schematic we got from a Chinese website who claimed to have unlocked 2 extra cores all we managed to do was confuse the bios into believing it was a Phenom and not the Athlon (no extra cores)

Personally I'd just get a better board, but at the end of the day your board your choice. Have fun :)
 
Just out of curiosity, have you tried using AMD Overdrive to up the voltage at all?

If that doesn't work then I think a hardware mod (non pencil mod) would be required, all the same it wouldn't be worth it.

AMD overdrive can't change voltages if vcore control in bios is disabled.

I want to push my mobo to its limits i dont care if in sets on fire
someone must have a knowledge either to mod the bios or to hardware mod it. I need to contact some famous overclockers :)

Are you sure? I seem to remember doing it on a Llano laptop + using PState set or whatever it's called to overclock the CPU side of it.

all it can do is just auto tune my cpu (just frequency :(

and i think you mean amd overdrive and k10stat

moving the voltage sliders does nothing, bios is locked

I don't think you're going to be able to achieve what you want with that motherboard. If there's no variability built into the hardware of the board to increase vcore, then you're stuck with it. Considering how simple it is to replace the motherboard with one that has variable vcore (my £38 Gigabyte AM3 board does!) compared to attempting to hardware or software hack your current mobo, there's not a lot of help to be given here.

All IMHO of course.
 
Im just going to shade the resistors close to the epu while my pc is working and see which one rises my vcore/lowers vdroop

I found a glitch in amd overdrive that lets me set the voltage way over what is specified the bios specified . will post in few minutes.
the max amd overdrive let me set was 1.43v, but with the glitch involving turbo thing i made it 1.55v
