4790k experience

Andrewf · February 27, 2015

So, I got the 4770k at first, then realized the 4790k exists. Got that, then overclocked it to around 4.8Ghz @ 1.312V. Not bad, okay, cool, idle temps under 30c, I was on top of the world.

Until I was importing some video into Avid MC and suddenly, I am disappoint. Just crashed as I was on my phone. Importing! Of all things, no not rendering, not converting video, not editing, fucking importing. Anyway... I returned it to stock settings since I was a little nervous because my Intel PTPP hadn't passed it's 30 day waiting period yet. Oddly, the idle temps are above 30c, and this worried me. I also noticed that with adaptive voltage still active, Aida64 was reporting my voltage to be at consistent 1.28. and my clock at 4.4 or 4, or whatever. Not sure what's going on.

I said fuck it, my Intel PTPP is active, so I started overclocking again, just now actually, forget the idle temps. I got it back to 4.8Ghz, Stable for about 15 minutes @ 1.32V max temps reaching around 82c, but average temps under load were still 72-76c so I wasn't too worried, 82c was just peak. I have a corsair H110 by the way.

I proceeded to overclock more because fuck it, I have PTPP. 4.9Ghz proved a hardware failure at 1.345V even in Aida64 after only 15 seconds. Temps peaked around 85c, is it worth trying for 1.35V? Is it worth it for me given how much I care since I have PTPP, and a voltage of 1.36 or 1.37 probably won't degrade it enough to shorten the lifespan by much considering I have a free CPU if it's destroyed and by the time I destroy the replacement, I will be looking at an upgrade anyway? The temps in Aida64 peak around 82c at 4.8Ghz, but rendering video, it stays around 60-65c, so real world temps are not a problem obviously. What say you? Also why were my stock idle temps higher after it crashed?

It's currently at 1.35V @ 4.9Ghz and I'm going to test it now, i'll update with results.
