i7 6700K: Good overclock or not?

[iwillruinyou]

Hello guys!

Just recently I overclocked my i7 6700K to 4.5 GHz at 1.250 VCORE. Is that a good state or should I try to lower the VCORE?

I tried to run Intel Burn Test v2.54 for 20 runs and the system passed it. I also tried Firestrike Extreme and it also finished just fine. What else can I do to find out whether my overclock is truly stable or not? Should I try AIDA64 or Prime95 and, if so, for how long should I generally run those tests?

To be honest, the only reason I actually decided to try my hand in overclocking is because I noticed that my MB was setting the VCORE at something like 1.3 at stock clocks and the temps were also pretty high. So I looked at some reviews and Skylake overcloking tests and decided to try 4.5 at 1.250 which turned out to work fine, at least for now.

Your suggestions are very much welcome.

Cheers, Ruiner

This is actually one of the tests I used as a reference. So should I also try HandBrake, as it seems to be the main test to cause system instability even though other tests report no errors?

If you are satisfied @ 4.5Ghz I see no reason at all not to try backing down the voltage, unless of course you want to go for broke and keep pushing the overclock without adjusting the voltage.

I know that it would be the logical step, but I'm afraid that I might damage the components if the system would crash or lock-up. If I do lower the voltage, should I do it at 0.005 steps? And what tests should I run afterwards? Should I just stick with Intel Burn Test and Firestrike?

Perhaps try prime 95 with your current settings to confirm stability. And yes always lower by the smallest increments possible.

As for prime 95 try the blend test.

No disrespect but prime 95 heats up your CPU unrealistically in my opinion. Using it of course is up to you.
I personally use Asus Realbench Benchmark and stress test (handbrake is also utilized in the tests).

Don't be afraid of BSOD they are a helpful indicator of what needs to be tweaked to stabilize your OC.

No offence at all. I could see that, but at the same time, if it cant take it ... its not likely stable.

All I'm trying to say is that testing for stability can be achieved without forcing your CPU to reach 85 - 90 degrees.

Thanks for your input guys, much appreciated. Yesterday I actually had a BSOD while playing Crysis 3. Consequently I increased the voltage to 1.255, but it also resulted in a BSOD. I don't seem to have this issue while gaming at the default settings. Does this mean I should keep increasing the voltage?

The voltage you see the motherboard run at stock clocks are a good indication of what you can get away with your overclocking, if the M/B ran it safely you can trust that.

From all you've said I see you're heading in the right direction you just need to fine tune it.

See if this helps you.

My link to you covers that but yes you need to increase the voltage to stabilize the overclock.
