Can this be true

I think that i have stable ryzen 2700x on 4.2Ghz 1.3125v. I have done stress test in prime95 for 20min and 30 min of rendering on very high settingsnin 3ds max.Currently using this settings for 4 days, didnt get freeze or anything.
Maybe temps are bad for this voltage but i dont know, 75 degrees of celsius for max(in prime95).

Is this safe for running 24/7. Voltage is pretty low, but again i get high temps when stress testing

75 isn't high...not ideal (≤70C IMHO is ideal) Anything less the 80C is safe though. Voltage is actually higher then I would like. i try to keep things at <1.3V but your pretty close. Did you try tinkering with Vdroop (or platform equivalent...usually load line calibration). While it increases heat it usually allows you to get the same stable results with lower voltages at the same GHZ due the less voltage fluctuation. And if you get the volts low enough your temps can actually be better then what you have now.

Well I didn't play with load line calibration, I'm pretty new in term of overclocking.But i saw it in bios, i have 5 levels of it.

Each level up on load line calibration (LLC) usually decreases the voltage fluctuation more, increasing heat more a little with each bump. But as stated get the voltage low enough even with high LLC and the overall heat can be less then what your putting out at 1.31V so you get two birds with one stone! Less heat less volts making a long term OC more safer and more stable.

It is trial an error like most overclocking. Just keep tinkering with it. I'd start by lowering the voltage to 1.28V (approx or a hair less, not more). Then enable LLC. Start with the lowest setting then stress test it again to see if it is stable. If no...increase LLC if yes though, lower the voltage some more and again start low on LLC. Keep repeating lowering the voltage and increasing the LLC according to find the sweet spot for volts and heat. You'll just have to guesstimate yourself to the sweet spot is all.

I have put it on LLC3 automatically temps are lower in stress test.Vcore is now on 1.254 V, and core VID are on 1.275V ( Dont know is that the same thing vcore and vid ). Currently max temps are 70 degrees of celsius.

 

[d.todorovicwork]

I will play with it, until i find the sweet spot.

Sorry was watching a movie. Glad you're getting the hang of it!!
