Overclocking 1700 problems

[smartroad]

Howdy all

 

Part of the reason for getting the Ryzen 1700 was to overclock it (with a hopeful target of about 3.9GHz). I have never really done serious overclocking before, my last machine was able to do some automatic overclock for my i5 and I was happy to leave it there.

 

I have managed to get the machine up to 3.7GHz and it runs okay under normal loads, even gaming it is fine with. However when I hit it with synthetic tests (Aida64 for example) it will run for a while, then the screen goes black (although I still have a mouse pointer I can move about okay). Eventually the screen comes back up and Aida is still running. A short while after that Aida will error and stop the test.

 

What I am trying to figure out is what the problem is. My PSU is about 5 years old now so it could be browning out. I might not have enough extra voltage on the CPU - although that doesn't explain why the screen goes black but with mouse pointer? Looking at the voltage I wanted to be clear with myself, in the bios it says +x.xxx voltage, is that saying that voltage plus the base voltage? What target should I be looking for with Ryzen before it is 'too much'?

I am interested as well, since this is pretty much what i want as well. (as soon as funds allow)

PSU sounds sort of like a reason, but i am not certain about this. As a rule of thumb though: never skimp on your PSU to save money, ever.

Linus recommended voltage is 1.35 but if you have the cooler some say its fine to go 1.4

Increase voltage and see if it fixes the problem

PSU could be it. Also linus' voltage recommendations are super conservative. Ryzen uses more voltage than 1.35V stock with the voltage on auto lol. I'm sitting at 3.9GHz stable at 1.425 V and can get stable 4.0GHz at 1.475V (don't really recommend the latter as we don't know the long term resilience of Ryzen yet).

Amd say 1.45 is fine for everyday use if you keep it cool,

you also want to set the llc up very high to avoid vdroop 

my board on max llc just about levels it out,

try 1.4 at 3.9ghz with llc max and see what ur vcore is under load in hwm

and adjust accordingly
