why do i always require high voltage?

[sendatooli]

every fcpga chip i ever had (5 of them so far) has overclocked well above what i would have expected. only problem is they always require 2.0+ vcore to do so. everyone else seems to get the max overclock at near stock voltage. especially with cc0 chips. ive changed all my components too. the only same thing i have is my alpha pep66 and delta fan. heat has never been my problem.
currently running fcpga p!!! 700 cc0 at 1008@1.98vcore. wont post at 1050.
but it is stable in prime95 at 1008.

what am i doing wrong? or am i just continously unlucky?

thanks,
sendatooli.

Your experience tallies with mine- I have NEVER had a good overclocking chip anywhere near default Vcore in about 15-20 attempts. I just watch the temps, if they stay in line I don't worry about the Vcore. I have a couple running 1.9v and they have been up 24/7 for months.

Aggresive burning in has been the only thing to eradicate this for me.

2 weeks (24/7) of CPUBurn at a stable speed sorts any high voltage issues out. It also tests your patience too!!!

I know what you mean though - my 1st cB0 core at 1008 took over 2.00v and created a Chernobyl like reaction on my die cap.

Silicon doesn't decompose until after 1300°c after cross linking and sintering - but the Dow Corning 340 interface grease was making a strange smell!!! Only kidding.
