Overclocking Ryzen 1700x. High voltage, and what is VDDRC SOC?

[KwebbleKop]

Hi,

I'm overclocking my ryzen 1700x cpu and getting weird numbers. I've seen others get 4Ghz at 1.35-1.4v. I'm able to hit 4.0 Ghz at a lowest of 1.48750v. I have a Corsair H110i water cooler that's been keeping the temps under a nice 60c max, and all I've been changing is the CPU core voltage and the speeds.

Because the max voltage is 1.55v, is my 1.48750v too much?

Also, there's this VDDCR SOC voltage that is always at a static 0.9v. I have no clue what this is, and others are saying don't go over 1.2v with it. Because mine's so low at 0.9v, does changing this help my overclock? What the heck is it anyways? I've heard conflicting answers to what this voltage is.

Thanks.

Hi there. I wanted to see where you are getting this 1.55v from? I've seen over 1.45v is going to damage the CPU. Not all CPUs can get to 4Ghz. The silicon lottery, OC knowledge, and risks are involved in the process. Full system specs would be a start for help on here. For people with good cooling, Ryzen temps won't be the limiting factor in overclocking, voltage and silicon limitation will be(LN2 and exotic cooling are another story). It sounds based on your post you jumped right into OCing without getting a good base on how it works, at least in regards to Ryzen.

Regarding SOC, its voltage is tied to the IMC for the CPU among other things. Adjusting this voltage(higher or lower in some cases) can help folks get to or stabilize higher memory frequencies.
