Undervolting Too Far

Taking the VCore down another step from 1.3v to 1.25 and the Ryzen 7 2700X still happily runs all eight of its cores at 4 GHz. 16 threads of 4 GHz power was the stuff of either dreams or the extremely well-heeled not that long ago. It is incredible how Moore's Law remains accurate in the 50+ years since it was first postulated.

It is tempting to keep dropping the voltages without paying close attention to clock speeds and the performance of the system. Certainly if you lived your life simply by stability booting into Windows and how happy CPUz is to show you the fruits of your labours then you might be of the opinion that 1.2v seems feasible. In actuality this has taken things too far and the Ryzen 7 2700X starts to drop clock speed and overall performance if you take things down to this level. At 1.2v ours was dropping to 3.8GHz under load situations. Still, 0.2v lower than stock is a massive drop, so we wont need to go back up too much to attain a system that has a fully stable 4 GHz, eight core CPU beating at its heart. This is why you should always take screenshots and keep an eye on what your system is doing, it maybe stable but you can easily make it slower!

"nobody wants to put 1.4V 24/7..."

But damn i wanted 3.9 so badly. I guess... well. Maybe. Mhh. You made me think. Maybe I'll tinker with it a bit more and see how far 1.3 will get me xDQuote

1.4v is safe for Ryzen. AMD recommends no more than 1.45v for extended periods. So personally 1.4v is the max I would go.

As for the article it's crazy to see how that bump from the optimized 4ghz to the 4.2ghz max clock changes temps and power draw. Definitely not worth 200mhz..Quote

I've been looking at the x470 Prime for a 2700X build, and the heatsinks don't fill me with confidence. How were VRM temps during testing?Quote

You should be fine honestly. Unless you are maxing out the CPU on a OC you'll be alright.Quote
