I can suffer from degradation using a 6700K at 1,440v @ 4.8 ghz with a Noctua NHD14 at 75ºC ~ 72ºC, peak of 81ºC? It's summer time tough, my room was pretty hot when i record those temps biggrin.gif

1.44V should not cause any degradation of the silicon but your temps are quite toasty. If I was you I would reduce the speed down to around 4.75 ghz using BCLK which should reduce the temps quite a bit since you are on the edge of stability of the chip. This will provide nearly zero performance hit and keep you well within the safe zone. Either that or look into a better cooling solution.

really? thought i should be worried when temps hit 85ºC+, that's bad news for me

i let my PC running GTA V on 4K for hours straight and temps between cores keep jumping between 65ºC ~ 72ºC, sometimes 76ºC on one core for one second, then go back to 70s... and that's it

i'm using thermal paste Cool Laboratory Pro aswell

I upgraded to a 6700k hoping to get some decent clocks compared to my currently crappy 2500k (4.5ghz@1.38vcore). Seems like it struggles to run prime95 for more than 15-20 minutes at 4.5ghz/4.0cache/1.32vcore. Is this chip pretty bad? I was hoping to have something that easily clocks 4.5ghz with lowish volts. Best chip I ever got was a 3770k@4.5ghz/1.19vcore, but that was for someone else.

I bought this from microcenter, so I have the option to exchange, I just hate doing it, but bad chips always seem to give me lots of trouble years down the road when I have to up the vcore more and more to keep the overclock completely stable. I'm also worried I won't be able to use an air cooler without getting a decent chip.

If under real world usage you stay around 72C then you should be fine. If you are gaming at 81C for long periods of time at 1.44V then honestly you will prob be fine but then again you are pushing the boundary. The difference between .25ghz is absolutely nothing and since on the high end of the chips stability the required voltage increases exponentially may allow you to remain stable around 1.4V which should provide quite a bit of temp decrease. Really though you most likely are fine. Nobody can say with 100% certainty that you are fine however. I only say do the reduction bc when giving someone advise about their system they put hard earned money into I always error on the side of caution.

If you have your airflow configured properly air coolers can match that of a CLC cooler. Don't be afraid of voltage. Skylake chips are very robust. Keep the voltage within 1.4 or 1.44 if you can keep it cool. Test the max clocks at say 1.4V and see what your temps are. Each setup is completely different so all that can be done is experiment. My guess if you can cool it you are looking at 4.7-4.8 at 1.4V. Also since you are running air I highly suggest not using prime. Run something with a much more realistic load and temps as x264 posted on the first page.

Well, for fun, I tried 4.7GHz(4.0cache)@1.41Vcore and it didn't even last long on that test, which probably means this is a below average chip as usual. Just a bit sick of getting these, since I always get the below average chip that runs hotter than I'd like, but it was fine since those were all soldered.

Forgot to mention, I'm testing this all on a custom loop my brother made for his PC in the interim. I get temps around 70-72c max, but that will go up once I have to up the voltage even more.

Yeah if that's the case then it looks like it's not a great clocking chip. What you could do is take a look at siliconlottery.com they offer prebinned chips at various price points. It cost a little more depending on the speed you go with but its worth it IMO. You know exactly what you are paying for and they are incredibly helpful to all of their customers.

I actually wanted to do that at one point, but I think this was all 450 after tax at Microcenter, so the deal was pretty good. I could exchange a few out to test since they allow 15 days on CPU/Motherboard. SiliconLottery was always a fallback if I kept getting screwed over. All I want is an average chip (maybe a bit above average), but I never seem to get those. I always just stuck with the below average chips I got. frown.gif

Thanks for the quick responses by the way. I appreciate it.

No problem I do not know much about micro centers since the closest one is around 3 hours away. Seeing how great they appear to be I'm always super jealous when I hear about the crazy deals they have.
