Help me with my overclock

[Chris_2503]

Hi there

 

i have i quistion. i am overclocking my cpu (r5 2600) it is at 4.1 ghz now at 1.35 volts.

 

so after i got into windows i ran occt and it gives me this message about errors.

 

is this somthing i need to worrie about?

if yes how do i fix it?

it means your overclock is not stable

4.1GHZ is something you don't usually get under 1.40 volts. I overclock Ryzen CPU by setting Vcore to 1.45volts, then increasing frequecy until iT where is crash on Cinebench R15 after 10 runs or Aida64 stress test. Then is lower CPU frequency about 100mhz, and now i lower Vcore until it crash again.

So lets say you increase Vcore to 1.45 and the CPU doesnt crash at 4.05ghz but crashed at 4.1ghz, i will lower the frequency to 4.0GHZ. Thats you probable max stable frequency, i now lower Vcore until it crash again, so lets say you CPU crashed after 2 pass of Cinebench at 1.38 volts, increase voltage to 1.40 and stress test for a good 15 minutes at least. If it doesnt crash what i like to do is increase it again to like 1.42 vcore and call it a day. You can stress as much as you want, but thats what i do and never had a crash so far and i takes about an hour or two to overclock, and its better then stock.

Using Voltage offset is a good thing instead of using static voltage, it helps to cool the CPU at idle.

 

Also try to reduce overclock of the CPU before OCing the Memory, and i would OC memory before the CPU

You really don't want to go over 1.38v on Zen+ though AFAIK. A 100Mhz increase probably isn't worth it if you can't push that at 1.4v or less.

Depends on each CPUs, i know my 2700 will run 1.60volts with 4.3GHZ, but that was for Extreme Overclocking purpose. As AMD_Robert said, 1.45 is within safe voltage and 1.2 VSOC is maximum safe, that being said, the CPU gets really hot with 1.45, hotter then i can live with for gaming.

I'm personally running 4.125GHZ on my 2700 with 1.38Vcore and 1.1Vsoc and don't worry about the CPU dying anytime soon. Memory is a 1.45volts and is still within safe voltage too, some people have been running their 1.35v rated memory at 1.5volts without any issues for years.

Really? I've seen a lot of members here , myself included, having 4.1Ghz OCs under 1.4V.  Mine for example runs at 1.32V. Either we are the top percentage of lucky silicon lottery members or they overclock better then you expect

I believe I got my CPU to 4.1GHz @1.38v, but I'll have to double check and see.

You my friend won the silicon lottery AFAIK, i'm running my 2700 4.125ghz at 1.38, i'm probably able to run it 95% safe at 1.35 but i just want it dead stable. 1.32 at 4.1ghz i just can't, 4ghz i'm probably able to do it.

There is a point with Zen+ where you need to increase voltage a fair amount to get lets say 500 more mhz.

Oh i am sorry, maybe there was a misunderstanding. For me , I am talking about my Ryzen 5 2600 since that's what the original post is about. Don't know anything about how the 2700 behave!
