Did the pencil mod on my Asus P5KC last night as i think i was suffering quite bad vdroop. Before the mod I was experimenting with the vcore set in BIOS at 1.45, this showed in cpu-z as 1.40 at idle and then 1.320 under load (so quite a big drop)

After having done the mod i am now getting 1.440 in cpu-z at idle and also under load (it doesnt change). I hope this is a good thing, but should it actually go down a bit under load for safety reasons or is it ok running the same at idle or under load???
 
If it's not dropping at all then i'd personally see that as a good thing.

Not sure myself but if it was drooping to 1.32 under load before (and was stable doing that) then would that not mean you could run the chip at that voltage in BIOS and still have a stable machine?

That was only running at 2.93ghz and i wanted to go higher , and anything above that wasnt stable. To achieve 3.4 (325x8) i was having to run the vcore at 1.55v in the BIOS. Since the pencil mod i can set the vcore to 1.425 and its stable. Regardless of what i do I cant get any higher though which is frustrating
 
This could be the answer I've been looking for,let me explain I've been clocking from 3 gig upto 3400/3500 vcore 1.45 in bios and only just prime stable it sometime fails to boot up othertimes it crashes while playing cod4,its not like i haven't heard of this pencil mod before but was under the impression that it was for higher FSBclocks over 400,:)
Your thoughts
 
I am new to all this so probably not the best person to comment. Have you checked what happens to your core voltage when its under load as opposed to idle (using CPU-Z or similar)? Does ir drop a lot when stressed???
 
Ive just completed the pencil mod after a Google search i found that a 2B pencil was suitable after trying this with a HB without success as the higher up the scale you go the softer the graphite becomes and will basically stick better well i have my computer stable @ 3500 cpu-z says 1.360 it actually goes up to 1.368 running prime95 1.42 in BIOS No droop at all @ load , must have over dun nit :cool:
oh i had to look hard to find a 2B eventually got one from a hobby shop and had a choice from 2B to 6B bought both have not used the 6B yet the 2B works perfect;)
