3770k safe voltages and symptoms of overvolting

post #1 of 37
Thread Starter 
Hey guys, I'm wondering what the maximum safe voltage is on a 3770k, and what the symptoms of overvolting would be. I am currently running her at 4.8ghz@1.290v (don't worry, i have a nh-d14 so I'm fine for a little bit more, hoping for 5.0 before I have to go for a custom loop) but it seems to either freeze up or BSOD when attempting to run stuff like BF4 and CoD: Ghosts. At this point, I am wondering whether to increase or decrease the voltage. I know I'm running low for something above 4.5, but she's been stable on low voltages for some reason. Thanks for any pointers/help/yadayada

Nice chip you got! You can use around 1.35v+ safe for 24/7 use if you cool it properly. 1.4v is fine to if you are a little daring, more than that and the chip will degrade quickly. Around 75c is max safe temp I would say, as temps kill faster than voltage.
Still 4.8ghz at your current voltage is very good, and you don't really need more.

Can you pass Prime 95?

If the ambient temp has gone up since your last stress test you should increase the voltage a bit.

If you can get 5.0 ghz at 1.32-1.34v that would be great. (Stable of course)

I folded on my ivy for 6 months at 1.48 vcore I say anything under 1.45 is more than fine honestly but with your chip you might be able to get around 5 gigglehertz at 1.35-1.4 range thumb.gif best of luck with that nice chip!

OK, so I tried running prime95 at 1.29v and it had 3 hardware failures immediately, followed by bsod. So, more voltage required. I bu!mped the voltage to 1.325 and it seems establish after about 20 mins save for a rounding error on thread 4. Thinking maybe another .005v might fix it up.

Yep, and it seems to fail prime95 blend test all the time, never being the same core failing

EDIT- forgot to mention that I'm running it at 1.35v now, it wasn't stable at all at ,25 and so I kept stepping it up

A friend of mine had a 3570 running at 4.5 GHZ/1.34V. After some months (<6) it couldn't pass prime at that voltage and decided to lower the OC. It was prime 24h+ stable.

Mine died at 1.4v after a year or so.
