Safe maximum vcore

I'm overclocking my E5300 at the moment and so far I've managed to get it stable at 3.4GHz with just less than 1.26 vcore. The temps are maxing out at about 55C on OCCT so obviously I've a bit more room to move. I'm wondering what the safest vcore I could use on this chip is?

Thanks
 
Maximum safe vcore is dependent on operating temperature and desired lifespan.

Over 1.45V is considered very unwise, 1.4V reasonable if you can keep it cold (say, under 60) and 1.35V is probably good up to 70 degrees or so.

These are approximate, as they're a mix of my opinion and a guess at how cautious you might be. I'm also assuming you're on air or on water. The approach I take is to pick a speed I want it to run at, then see if I can get it there with reasonable settings, then minimise voltages. If it turned out to be too easy I then pick a higher speed. On yours, I'd probably aim for 3.6ghz, then get voltages as low as possible there.

Thanks, your help is very much appreciated.

Surprisingly this is still on the stock cooler; I've a CoolerMaster Stacker so the system is reasonably well ventilated. Any more than 60 and I'll be more cautious with the increases and if needs be I'll get an aftermarket cooler.
 
You're approaching this from the wrong angle. The question you should be asking yourself if how long do you need it to last while overclocked?

If the answer is a long time or greater then 1.45V is probably the limit, if you're not fussed on a long-term overclock then go mad. When it fails to hold it's overclock then you can either increase the voltages a bit, sell it (obviously being honest about it's history) or give it to your Mum as a free upgrade for her PC.
 
Currently have a E5200 here sat @ 3.33ghz at 1.3625volts set in BIOS. Board undervolts a fair bit in windows, CPU-Z reports 1.344volts.

As to the question, well, I tend limit overclocks to no more than 1.45v to be honest. Less if I can get away with it, or I've hit my overclock target.
