Ryzen 1700x boosts itself to 3.9 on all cores

jpe1701 · Nov 22, 2017

Hi,
So I'm just wondering if anyone else has seen this behavior? When I game I have HWmonitor running so that I can check out temps and stuff. This is a recent build so I only have 3 games downloaded so far but according to hwmonitor, my Ryzen 1700x is boosting to 3.89ghz on all cores. Now I have no way of knowing for how long it does it, but I thought the 1700x had a max turbo of 3.8 on 1 core with 100mhz xfr if power and temps are good. Am I wrong about how xfr works? Is this normal?

It's never a round number because FSB/BCLK varies.

Yeah I understand that, but I didn't think it would boost all 8 cores that high. I thought it was limited to 1 core. I'm definitely not complaining though. lol. Just it works better than I expected. I can't maintain 3.9ghz though when I overclock without more voltage than I am willing to use, I gave up at 1.3875v. I use 3.8ghz at 1.375v when I want it overclocked, but I am running at stock since I only want the extra speed when I am rendering a video.

With good cooling, you're just fine with 1.4v and no, Ryzen can turbo on all cores or just few as required although a BIOS like on my MB has settings to limit boost to 2 or 4 cores.

Thank you. I will have to try up to 1.4v. I don't think I will need it though since it seems to really do well without overclocking. I noticed something too, if I have ryzen master open(which I do sometimes just to monitor the cpu temp) it doesn't turbo as high. I even ran cinebench r15 a bunch of times and with master open the scores were almost 40 points less. Anyways thanks for the answer.

RM takes a good chunk of resources to run but doesn't change any settings unless you save a particular profile.

I will have to find a different solution for watching my temps. I think hwinfo64 is accurate. I don't use RM with any profiles because I prefer to do it in BIOS. I have a Taichi x370.

I use HW Info for monitoring.
