Max safe voltage for 3900x overclocking?

Currently looking to overclock my 3900x,  I've been enjoying it since July.

I'm currently making my first attempt at overclocking with this chip since I have the time and would like to know what is a good starting place.  RN I just have PBO on with a -.1 voltage offset, using Dark Rock Pro 4 as my cooling solution, looking to try getting a decent all core OC or per CCX OC

Re: Max safe voltage for 3900x overclocking?

As long as you stay under 1.45v and 90*C you're fine for long term use. Ideally though you should aim for no more than 1.4v and 80*C.

What's the max oc you've seen on 1.4v?  I've gotten to 4.3ghz on 1.2v

Re: Max safe voltage for 3900x overclocking?

I'd recommend going with a manual voltage setting rather than an offset.  Start with 1.25v and work your way up.  With the latest batch of CPUs I've been able to stay under 1.33v in every case...but all have had VERY good cooling solutions.  In any case, as other have said, stay below 1.4 for long term use.
