Am I overclocking correctly?

So far I haven't changed much. First thing I did was run aida64 on stock settings, my max voltage was about 1.15v and I wanted to see how far I could get without increasing it over what im assuming is the default boost clock voltage. So far I've gotten to 4.4GHz on 1.15v, Ive never seen any posts anywhere mentioning anything this high without atleast 1.25v so now I want to make sure im doing everything right and make sure Im not overlooking something.

The only stability testing ive done at 4.4 was 11 minutes of AIDA64 which I know isn't enough to call it stable but Ive been running it for 10-15 minutes then increasing the multiplier by 1 with seemingly good results.

I'm not a massive overclocker but should be able to help a little.

You kinda pointed it out yourself. Your only running a test for 11minutes, thats really not long enough at all. You don't need to run it for hours in-between clock changes but probably 30minutes on a heavy stress test is the minimum for a quick indication of stability. Also try using a different stress test to back up your results.

for example I run intel burn test and then OCCT.

Try running CPU Z to check what your Vcore to see if your bios changes are actually taking effect. sometimes there is some setting overriding and increasing the vcore as needed.

You can achieve a lower vcore by changing other settings as well such as uncore ratio and even ram frequency, however this is unlikely to produce dramatic differences.

Lastly there is always the chance your cpu is just in the top 5%.

I'll do an hour long test at 4.4 because 4.2 was all I was really after, if it's stable I'll go a little higher.

I am running CPU-Z, and it's included in the first screen shot. It confirms that I'm running at 1.49v. The only number that im questioning is the uncore is still at 3.8.

Ow sorry yeah should have looked ::(.

That uncore is pretty normal so that wouldn't be it. I would think you have a pretty decent cpu and its coping pretty well with short stress testing, I would think it would likely not be stable at that clock for much longer however if its stable for 11min its got to be above average for sure I would think.

Count yourself lucky and stress it a lot more I would try OCCT as it normally finds problems pretty dam fast. There isn't really any setting you could have turned on that would cause it to perform so well at low voltage.

Sweet, have you checked your ring voltage and Vrin compared to what others are at? My guess is you just got lucky. I have seen some of the new 4790ks that run a whole .1 lower than mine and I think I have a fairly decent one. Hopefully this should mean you can get a great overclock on it :)

I have no clue how to check the ring voltage. All i can say is that in the 2 and a half hours I ran the test it never exceeded 1.15v measured in CPU-Z, HWiNFO64 or CPUID HWMonitor. In OCCT ring offset id go to 0.01v on the previous test, on the current test at 4.5 GHz 1.15v HWmonitor does register max LLC/Ring Offset as 0.004v. I'm currently 10 minutes into the test. Crashed at 12 minutes, 4.4 is the limit for 1.15v.
