Hello, I just oc'd my cpu today to 3.9ghz, 1.4v (haven't tested stability yet) and when on idle i watch it doing some temp spikes every 10 seconds. For example from 43 to 53. I saw some articles saying about ryzen master causing this but i didn't have it installed.

Anyone?
 
I would see what the temps look like when stress testing to see whether thermals are an issue. What voltage are you running? Remember not to use over 1.4 volts.

I would run aida 64 or an older version of prime 95 (someone comment the non avx version) and hwmoniter to test stability and thermals at the same time. Those programs are free. Aida 64 and prime 95 stress your cpu for stability and hw moniter can check for temps. Make sure neither stressing program throws and error meaning your oc is unstable. Also make sure your temps are under or around 80c while running aida 64 and prime 95 using hwmoniter.

I m now playing league of legends and temp is stable at 60-63. I'm running at 1.42v is it bad? I will test stability with prime95.

About Temps I read somewhere that 85 is OK for oc'd cpus at stress testing.

Keep lowering voltage till it becomes unstable then go back up. The only way to lower temps is to lower voltage or speed. (Or get a better cooler)

As mentioned don't even look at idle temps they mean absolutely nothing unless they're like 70©

Just keep dropping voltage a bit and see how low you can get it each step.down will slightly lower max temps under load

First of all I want to solve this spike problem because my fans go harder when on higher temps. On prime 95 i got 93 degrees before the system freezes xD

I tried 3.85ghz at 1.38v now and for 8 min, temp reached 92 degrees. Maybe it is because I applied thermal paste 5 hours ago. I have an intake 12cm and an exhaust 12cm fan.

But I have another chance ;)

Guess what? When my pc wasn't posting because of my ram, I thought my cpu was doa so i returned it. It turned out to be okay but the shop was confused and they sent me 2 ryzen 3 1200 cpu's wheree the one was sealed. So I will try if this goes better.

Ok so I have a few questions. I didn't test the other 1200 yet but I was able to stabilize my cpu to 3.85ghz @ 1.35 volts. When I'm running small fft test at prime95 version 26.6, cpu vcore on hwmonitor takes different values (1.356,1.368,1.38). Why?

Temps stabilize at 87 degrees. Good or bad? I also run intel burn test and i got a message that it's stable. At 3.85 @ 1.33 it froze so i can't go below and i neither wanna go on 3.8ghz. Should I leave it like this? Also how would you rate my cpu for an overclocker?

It's probably right at the average for that chip. Maybe a tiny bit below.

Check your temps under normal useage if it's riding close to 80 gaming I'd dial it back some more as that's too hot for a overclocked cpu constantly

At gaming I have around 66 degrees which looks perfectly fine. Did you read about the different voltage values on hwmonitor i mentioned? Why do they happen? I have set cpu vcore offset from the aorus b450 pro bios to +0,20 which is 1.35v i believe.

I was running for some weeks now 3.85ghz @ 1.35v but never tried 3.8ghz. Today I tried 3.8 @ 1.3v and I was happy it was stable (I run prime95 for 10 minutes and intel burn test for 10 results which always can fail if my oc is unstable). But then I went at 3.8 @ 1.25v and OMG it was stable too!! Now on prime95 i only have 75o under load.

The other ryzen I had wasn't able to even reach 3.85 and on 3.8 it was unstable under 1.35v so I'm happy with my 1200 now :)

I know I know. Damn you were unlucky there. Mine couldn't go above 3.85 and 3.8 respectively. (Haven't tested 3.875 and 3.825 though hahaha)

1.5 you said? :ouch: Don't they say that >1.425 can hurt the cpu? I once tried 1.45 by fault because my mobo has offset and I was confused and I had black screen after bios.
 
Nope with an rx570 you will be fine. I have a gtx 1050 that performs 60% worse than 570. Yes 1.5 volts is completely unsafe for actual use but for a minute or too at idle just to run cpu z it wouldn't kill my cpu immediately, but it would have thermal issues. Fortunately, I never got into windows at that speed anyhow.
