what do you expect? grabeh kaayo na ug connections si yoyong, handpicked gyud na nga proc. if only i have the same connections, sunog-sunog gyud siguro mga proc diri ba.
as for my tip; get to know your processor very well. read its specified thermal and electrical properties. helpful links and good reads below:
Intel® Core™ i7 Processor - Technical Documents
data sheet na sa imong proc. you'll find absolute maximum voltage and temperature among other things. what's good is that its coming from the manufacturer itself rather than speculations and what-nots. one last word, limits depends on your preference, ikaw ra gyud maka decide unsa'y sakto na para nimo.
enjoy overclocking.
edit lang gamay:
this is not for the memory but for the processor itself (memory controller). you can run it higher than this specification but you'll have to maintain a certain percentage against uncore voltage. read between the lines sa datasheet, its there - wala gi-mention directly but there.
