Question about Overclocking?

[infiniteCurse]

So, to start I have a 8700k CPU overclocked to 4.9 with 1.305 volts. My question is in general if your system blue screens does that mean you need to add more volts to try and get a stable OC?

In a very basic sense, yes. The error you get on the blue screen can help indicate what the issue may be, could be unrelated. That does seem pretty ambitious though, I'd expect you to need more voltage to get to 4.9 tbh

A bluescreen related to overclocking simply means something isn't stable.

You can fix that problem by either lowering the core clock or upping the voltage.
How far you want to go with the voltage is up to you. At some point you will risk killing the chip.

Or you could just use better cooling/delid. You'll need less voltage to get your CPU stable with lower temps. 4watts every 10°C = ~0.02-0,04v

Keep a close eye on your temps when overclocking, as long as your temps are stable, then you should ok. I recommend running a Blender stress test. If your system fails the test then you need to stabilize more, if it runs the whole test than you are stable. Just a reminder that even though you don't get a blue screen, that you can still be unstable. I recommend the BMW version of the stress test. Keep in mind that this a very demanding test to complete and that it will take some tinkering. I also don't really recommend going over 1.4 volts, not sure if you can or not I just don't risk it with expensive processors. Let me know if this helps at all. 

 

good luck!

@DarkSmith2 So what youre saying is i need to decrease my voltts to get a stable overclock? so when it blue screens that means too much volts?

thats unfortunately not how it works  I didnt said you should reduce voltage for less temperatures, i said you should increase cooling.

 

Lets assume you run a Benchmark for stability, Prime95/Aida/Realbench whatever.

 

4,9GHz @1.305v and your temperatures are at 75-80°C the test does not pass and you get a bluescreen.

If you now decrease your temperatures f.e. with delidding by 10°C or even 20°C while using 1.305v the stability test should pass.

And it could even pass with 0.04-0.08v less then it would need to pass without delidding. (assuming you lost 20°C when delidded)

 

thats just how semiconductors work, less heat means less voltage is needed to get the overclock stable.

what does the AC load line and the DC load line do in terms of overclocking?
