pencil trick, not the usual how to question

i have a t-bird 900 on an ep-8kta+ running at 1000 @1.75 volts seemingly rock stable. i did the pencil thing twice (regular #2 pencil) and it worked. at over 1000, it isn't stable. i'm running winME and when i try over 1gig i get an error message saying error accessing registry. no biggie, that's just the first sign of instability, besides, i can ctrl+alt+dlt that message away. here's the question...since it boots at 1050 and posts at 1100, should i assume that the pencil lines are fine and the chip just doesn't like it over 1gig or could the pencil lines be the problem (and i would prefer not to do the loctite thing)? oh, and it's not a heat issue. i won't bother posting my temp readings since i think they are too low to be accurate but i'll just say that i have a pretty strong floor fan blowing on it and in upstate new york in my college dorm it is pretty cold in my room. thanks for any tips or tricks...

Since pencil lead is made of graphite, which is not designed to conduct an electric current, it's likely that you have reached the limits of your pencil traces, and you'll need to do a permanent fix (Loctite or conductive pen) in order for your system to be stable at those speeds.. (Or you may have just reached the limits of your CPU, but I'd definitely give the Loctite a try!)

although graphite is a conductor, it's not a perfect conductor, meaning that it will resist current and restricting flow by some degree of ohms. knowing this, it's best to do a permanent job using conductor pen.

that's what i was thinking. but it's not really stable above 1gig even at 1.85 volts. the fact that it does 1gig stable at 1.75 volts but won't do 1.05gig at 1.85 volts made me think it might be the pencil lines at fault. i guess i will try to do a more permanent bridge connection. damn this computer sh!t is addictive...i should be studying for my philosophy test that i have at 10:05am!!!

it may not be the lines that r causing the problems otherwise you wouldn't be able to change the mutiplyer at all, you could use conductive paint to make sure tho.

I think your problem might be the voltage because my duron will post at 1100 but it won't load windows and i know this problem is because of the lack of voltage

It may be the pencil. I've had the experience where it would POST up to 950, but would boot only at 800 using the pencil. Now I have used some of that defog kit stuff and it boots at 858.
