For my overclock I have got 1.406vcore/1.58PLL to last 9 hours small fft's before failing, I might get stable by bumping to 1.6PLL but instead I decided to try 1.4125vcore/1.54PLL which is currently running for about 3hours. My question is that if both settings pass 12hours (1.406/1.6 and 1.4125/1.54), which of these would cause the least amount of CPU degradation over a period of 12 months? Does increasing the PLL affect how much wear and tear you are putting on your CPU? Thanks, hope that is not to hard to answer
Since you are running a 65nm quad I don't see any problem in high voltages regarding Vcore nor PLL... but it's an interesting question... Only thing I would look into are ya temps... hows does the Zalman cope with ya CPU ? what voltages does ya CPU require for eg for 200mhz less ? so 8 x 400 ? or even 10 x 333 ? If the cores go over 60°C I would consider a beefier cooler there... could be you need less voltages then for 12 hour stability...

And to be honest, I never run Prime Small over 6 hours or so... then I run an OCCT 2 hour, first CPU then Ram and finally mix in a row... some 3dmarks and finally 4 superpi 32mb runs at the same time... till now no weird erratic behaviour with none of my CPU's...

We are getting obsessed with Prime and Orthos... while it could be heat, PSU, who knows what makes the stress program fail... also some peeps prefer Linpack... but my CPU is never tortured like that in real time , not even when folding 24/7 at 100%...

Best test is daily usage... if you don't have anything erratic while using ya rig and having fun... then it's stable enough for you... for someone else it might cap out on some program or co...
