Edit: Also thanks for confirming im paranoid guys ph34r-smiley.gif lol

Its actually really not a bad idea as instability usually happens in transient response not long duration loading. Especially if you use C1E/EIST etc. Although you might need more than .005v buffer to prevent any issues with that.

I'll throw a monkey wrench in here smile.gif

If I'm on a platform that has infinitely adjustable cpu frequencies (i.e. multiplier and blck/fsb adjustment) I'll leave it at the stable voltage and just reduce my cpu frequency down .1 to .5 Ghz and call it good after worst case toaster testing. Of course that goes out the window with P67/Z68/X79.

yeh ive noticed that. ive passed stress tests before but then found the computer crashes when the cpu starts downclocking, or sometimes when its idling. i sometimes also do an overnight idle test after the stress test. for this reason ive often found it better to lower llc and raise the offset voltage so that it idles a little higher. helps iron those issues out smile.gif i do use c1e btw but im not sure ive seen an eist setting before, or ive just ignored it cos it didnt know what it did!

overclocking my 2500k on this z68 platform has been pretty damn simple! these sandy bridge cpu's overclock excellently! my phenom 955 was much more of a pain in the arse lol...

i do the very same. i dont know if it actually increases the stability but to me it makes sense to bump it up a little more. i usually go 1 or 2 notches above and over the next week i'll lower it when i know for sure its stable....or with temperature problems. Can't be too cautious with voltage, am i right?
