I7 4790k overclock.

[p0mpous]

what is a good voltage for a 4.8ghz OC, im thinking about having it about 1.260, does anyone else have this CPU with a similar OC.

You just do 12-24hr runs to proove it's a 100% stabel OC, if you don't care if it's 100% stable, don't bother.

one thing i have noticed is that through Aida 64 it says my cpu is at 1.294v, yet everything else is saying its at 1.269v.

Welcome to software overclocking. (I made this comment with absolutely no proof to back up my claim of software OCing being the culprit) #TechFlame

well ive been running Aida 64 for about 25mins combined the program itself has stopped responding a few times, does that mean anything.

i tried 4.8ghz at 1.25, the test failed, now im trying it at 1.269 the test doesnt fail but the program stops responding.

No that is normal because the CPU is running at 100%. It's best if you do not use the PC during the stress test.

Just chiming in to reinforce what has already been said.

Avoid software OC. Windows doesn't play well with software OC and can cause unnecessary issues. BIOS has everything you'll need anyways.

Haswell Refresh (AKA Devil's Canyon) tends to fair the best under 1.3v, but can go a little over if cooling is efficient enough. Just be prepared for less stability, as it doesn't usually like to go that far over 1.3v without having stability issues. For everyday use, I'd recommend finding a stable clock with voltages under 1.3v. If stability is questionable, you don't have to lower all your clocks. You can set each core to different clocks.

Testing for long periods of time is needed, if you desire a stable system. Even if a system seems stable, you can get all kinds of stability issues that don't result in a system crash. The point of testing is to push past normal usage and try to make the system fail. If it fails, dial it back a bit and try again. If not, then you have a stable system. Just note that it is never a sure thing, even with a stress test.

Overclocking is more or less a skill. It takes time and patience. Keep at it and remember to have fun. The 4790K is a great CPU and they tend to be fairly good overclockers, despite the thermal compound issue.

What i dont get is Aida 64 is saying im at 1.272v when i set it to 1.250v in Gigabyte Easytune, CPU-Z is also telling me its at 1.250v, so if i go into my bios should i set it to a voltage above 1.25 or 1.27.

Getting different values from different programs is normal. Nothing to worry about. It is merely how these programs grab this value. FYI, you won't get a dead accurate reading on the voltage, regardless.

Im not worried more slightly confused, why would there not be a standard way to get the correct voltage.

Because fine electric measurement would actually take a bigger device to properly measure. You only have small modules on the board. They are more or less a guide and the purpose does not require dead accurate read outs. You also have different programs that are designed to obtain, and display, this data differently.

Just run your computer with this overclock for a few days and see what happens. If it starts crashing, then you know something is wrong. If it doesn't, then don't worry about it until it does.

Well im testing 4.7ghz in aida 64 it gets to about 78C on avg peaks at 84c, but how long should i run it.

So what's the point of oc, if u r scared of prime..

Im not scared of it, it just seems like a very bad solution to stability testing, why isnt their a more elegant way of testing it other then putting it under a load and producing far more heat then anything any average user would put it through.

It just seems like a very inefficient way of testing stability.

Cause the idea is if it's stable in that regard, then it should be stable doing lesser tasks.
So yea it makes perfect sense.

Never use OS software to OC CPU, do that in BIOS.
Lock in your RAM using the XMP feature. Try to get the CPU as high as your cooling allows, while using the lowest voltage possible at the same time. If a lower voltage can work and be stable, that's what you want to do here, always.

If you're seeing 80-90*C in things like Prime95, generally thats fine if it doesn't continue to rise. Always run these test for around 30 mins minimum so you can test both stability and cooling. Overall it's fine to see these kinds of temps, cause you then would generally never see it get that hot during Gaming. And if it did, at least you know already that it should be stable, due to having performed such tests already.

Is 1.308v safe.

[Bad 💀 Motha]

That's about as high as one should go on such a CPU as that.
Especially if you intend to leave that OC active for everyday usage.

Also, just because it may be deemed "stable" in a decent run of Prime95, does not mean it will be a stable OC in every thing you do, like some apps or games perhaps.

I like to use a series of tests, Prime95 and then AIDA64. Since AIDA runs the CPU through a different but also length set of other kinds of tests. You can use the trial version.

that the maximum it hits is Aida 64, in general use it never seems to pass 1.280v.

In prime 95 it hits TJ max pretty fast in Aida 64 it tends to stay around the mid 80s.

[Bad 💀 Motha]

Well that is good then, sure.

Some Prime95 tests are just unrealistic...
