After some fiddling tonight I've managed to get 4.7 Ghz at 1.3v

Temps are in a good range and now not hitting over 75 with some fan profile fiddling.

Will 1.3 volts seriously decrease the life of the cpu. I don't mind knocking back to 1.275 for a lesser OC if the chip will last longer.

You will be fine and nice chip!
What was you using to test you OC?

Using aida 64,asus real bench,prime 95,

Also did some multitasking and gaming with no ill effects. I only stopped at 4.7 cause the cpu temp was getting to 75 celcius when running aida. I'm using air cooling NHD14 and a extreme thermal compound

I'm thinking that maybe another custom WC loop could net me a seriously nice overclock
 
Isn't Prime95 like... Really bad for Haswell chips onwards?

I took Jedi's advice and just do a 5 min run of OCCT, a lot less effort than hours spent on AIDA, etc.

4.8GHz @ 1.3v didn't happen for me so I settled for 4.5GHz @ 1.21v.

Yeah I've just read about prime 95 so won't be using that again.

Just fiddling around now and seeing how low I can get voltage with highest OC to pass on OCCT passed 1.275 at 4.7ghz so now trying at 1.25v wish me luck. Not had this much fun in ages been out the loop far too long
 
Wouldn't bother with progs like OCCT, asus real bench is fine, just get it stable at the lowest voltage you can and then just add a couple more clicks vcore, so if its stable at 1.25v then around 1.265v should see it stable enough.

Stabillity is all based on what you use your pc for, if your permanantly number crunching with the cpu at 100% then leave at stock or a very mild OC and using prime etc to test for 3+hours is a sensible way to go but for gaming and general stuff there really is no need to test for hours or use programs that basically abuse and could quite possibly degrade your cpu. It amazes me when people brag it can pass prime for 24 hrs and all they do is browse the net and a bit of light gaming.
So cpu stabillity test = asus real bench
Memory stability = memtest (at boot) or memtest ( windows) but have 1 window open per core.

Thanks for the info. I'm generally trying to find a nice happy media and may try for a big overclock if I go custom WC again. I got 4.4 stable at 1.2. Passed asus real bench and mucked around for a couple of hours and seems fine. Also giving me a much lower core temp no higher than 65 now under general use nudging low 70's with OCCT.

I think 6 our right about stress testing I put OCCT on and my at the wall wattage was 342 whereas in the most demanding games I have I'm seeing a maximum of 270 to 280. Nothing I use will ever put all 6 cores under 100% full load so it does seem pretty pointless to push that hard.
