I say, as long as you can keep it below it's reported thermal threshold...volt her up...within reason.Jiggy X58A-UD7 - Intel i7 920 D0 +4.9ghz - Kingston Hyper-X DDr3 2333 - 2x MSI GTX 480

For 24/7 overclocks most people agree 1.55V being max long as your temps are good. Once you have found your stable overclock, best thing you can do is drop the voltage as much as you can and stay stable. Over time higher voltages will wear on the processor faster. So quite possibly in 2-3 year(or maybe 5 no true way to tell), your overclock will start to become unstable which at that point you can either add voltage or lower the overclock.Rig 1:Rig 2:i5-4670k 4.6 @1.29v :)i5-4670k 4.2 @1.29vGskill Sniper 8GB DDR3 1600 9-9-9-24 @1.5vGskill Sniper 8GB DDR3 1600 9-9-9-24 @1.5vEVGA GTX 780tiGTX 580 SLIAntec GX700Antec 1200Corsair h100iCM Hyper 212Seasonic g-750Antec CP-850MSI Z87-G45MSI Z87-G45Samsung 840 EVO 120 GBN/AWD Blue 1TBWD Black 750GB x2 Raid 0

AMD says 0.850-1.425V is the safe range for that processor.
For overclocking purposes the load core temp is a critical part of the answer, as far as I'm concerned. I've seen way too many people running 60°C or more and pushing 1.50v of more volts through there rig! If your load core temps (as shown by either OCCT or Prime95+CoreTemp) are 55°C or less then 1.50v is probably good. If you're below 50°C or, better yet, well into the 40's then even 1.55v can be pretty safe if your vCore is steady.
