Asus P5KC Pencil mod success!!!

[pistyll]

pencil mod 100% success!!!
After several failed attempts I have finally managed to get zero vdroop and also a great reduction in vcore from 1.4875vcore to 1.3250vcore prime 95 stable therefore my faith in pencil mods is greatly increased and after many many hours of varying degrees of pressure and amounts of hb pencil lead I finally managed to get the following results:-

Originally :- 1.424v with vdroop 1.336v = 0.088v vdroop
Now :- 1.3250v with vdroop 1.325v = 0 vdroop result!!!!



Stable in OCCT
P95 stable

great! but you have to remember, loadline calibration is there for a reason. i totally agree that .088v is way to much

Hi,
I have read elsewhere on other forums that maybe zero vdroop can be a bad thing and that a little vdroop is necessary and is built in to the motherboard as a failsafe?? even with zero vdroop and a greatly reduced Vcore I find the overclock to be a bit twitchy shall we say, my pc sometimes randomly re-boots for no reason at all but can then run for 4-5 hours without a flicker do you think maybe my vcore is a little too low for a 3.26Ghz clock??

i have heard of people that do vdrop mods and have there overclock prime 95 stable for days, but still randomly crash at idle. with that said, adding a little bit of vcore may help you

Hi,
took your advice and increased vcore a little to 1.35v in bios 1.336v in cpuz having thought about it a little my original vid was 1.325v and even with the pencil mod I am asking the cpu to perform some 35% over stock and I really can't expect it to run at 1.325v now can I!!!! anyhow seems a little more stable now fingers crossed!!!! lol
