How is my temperature & voltage? (3770K @ 4.7GHz)

[Peddeh]

So after running my 3770K at stock (yeah I know, don't ask) for nearly a year. I decided to finally to get some extra performance out of it and at the same time see how far I can push it (sensibly) before it's no longer stable.

I'm at 4.7GHz at the moment that's about as far as I'm comfortable going in this journey. Any further and I'll think I'm scared I'll be faced with a disaster lol.

I've been working on this all day, starting from 4.0GHz, and slowly incrementing the core and frequency, jumping into Windows and running a range of tests (e.g. Cinebench, IntelBurnTest and 1hour prime). It's now 2:51am, and I've made it to 4.7GHz and I've found the stable point of 1.288 voltage.

Temperatures as reported in HWMonitor (RealTemp was reporting the same values too) after running Prime
Min (idle) 30c / Max: 81c (with Arctic Silver 5 paste)

Is this voltage safe and is my temperature ok?

I've tried going lower than 1.288, but even a touch craps up in the first 5minutes of Prime. I should also mention I'm not using the best of coolers, it's just a standard Intel Liquid Cooler - I should probably replace this!

Anyway, enough of my ramblings.

Edit: should have listed the rest of the system

MB: MSI MPower Z77 (latest BIOS)
RAM: 16GB DDR3 2400MHz (standard XMP profile)
GPU: AMD R9 290X (x2)
PSU: Corsair 1200W
OS: Win 8.1 Pro 64bit

Temperatures seem normal for that level of voltage. I'd personally want something like an h100i for cooling, but it sounds like whatever you're using is doing the job. 80C is generally okay for the 3770k - keep in mind the temps you get in prime95 will be far higher than what you will get in real world use, generally speaking. I get 80C+ during prime 95 stress testing but rarely pass 65C in real world use.

4.7 ghz is about as far as people actually are able to take 3770k usually. I'd say you dun gud.

Going over 4.7 ghz would probably take delidding since you're probably going to need north of 1.3v to keep it stable.

If it crashes from backing off the voltage a notch, I'd say lower your Clock to 4.6Ghz and leave the vcore. I'd say you are nearing instability. P95, LinX, etc. don't catch all the errors so there may be some that just aren't showing up that could start corrupting your system.

When I kept my volts lower 1.29v I got WHEA errors in IBT x46 and x47 once the volts are are over 1.31+v no more WHEA errors.
It seems you have two choices a 44 multiplier with a lower vcore which many of smarter people run here or a 46-47 multiplier and a +1.3v.
Because I use wc I choose 46-47 multiplier and a +1.3v. on my 3770k.
