Hi I've overclocked my i5 6600k to 4.8Ghz with 1.320v, I'm new to overclocking and I am unsure whether this voltage is to high for daily usage? I am cooling on water using a Deepcool Maelstrom 240T. I have carried out a stability test on cinebench and run aida64 for 26 minutes and everything was stable.
Here's a breakdown of my results:
Core 0 highest temp: 55c (131F)
Core 1 highest temp: 62c (143F)
Core 2 highest temp: 58c (136F) ALL CORES RUNNING AT 4.8Ghz
Core 3 highest temp: 60c (140F) RESULTS PULLED FROM HARDWARE
Package highest temp: 57c (134F) MONITOR

Help is much appriciated and any other results or specs you need from me just let me know thanks guys :)

Try prime95 (version 26.6, don't go with anything past this), and cpuz to verify. If those both work for you, without errors, your system is stable. Prime95 is a very good tool to catch subtle problems with OC. It shouldn't return any errors whatsoever.

If the prime95 test makes your cores exceed 80c you need to bring the OC back to the 80c limit or get a better cooler.
Version 26.6 and before are the best realistic tests of thermal capabilities of the CPU.

I'm pretty sure that overclock will fail in a day or two. I've learned the hard way that if you're surprised that you could achieve an overclock at such low voltage, it's probably because it isn't longterm stable and you're just lucky it passed the stresstest :p I've even stresstested for 4 hours, only to have the overclock fail 2 days later

Well so far, I've been running it like this for about a week and had no fails yet, I'm a heavy gamer and I’ve also stress tested it about 5 times for an average of about 15mins each time and I’ve had no faults, does this mean I’m safe?

Sweet, I'm impressed it works :D Congratz so far

Isn't Prime95 more aimed towards torture testing the CPU for checking thermals for more extreme overclockers? In any way, it's a pretty overkill test imo.

There's a reason you get v26.6 or earlier. If your system can't run that (which it should be able to, OC or not), then your overclock is not stable. All it's doing is attempting to process a bunch of stuff so much, which your system could do one day during something important and fail then, and check for stability in a closed environment. IF your temps exceed 80c under V26.6 load your OC is too high and you personally take the risk of damaging your CPU in another environment where it gets under load.

You should be able to run prime95 for weeks without error or problem.

Ran Prime95 v26.6 temps reached 62 degrees Celsius and no crash, fully assuming I'm completely safe now! Cheers guys
