Overclocking Ryzen 5

[SupersonicSaint]

Edit: Just realised I posted in the wrong place but I can't move it or delete it.

 

My Ryzen 5 2600 is water cooled and I want to overclock. To hit 4.2ghz what settings should I imput? Or is it really this easy?:

 

1. Enable and start at 4100 MHz (41 Multiplier)
2. Apply 1.4250V to the CPU (or simply leave it at auto).
3. Enable XMP on our memory kit (3200 MHz CL14)

1.4250V

Thats really high, you should be about to get it with 1.375~1.380V

Thanks, I hope it works now.

While you can type 1.425V into the BIOS, voltage will drop whenever you put load on the CPU. You'll need a CPU core voltage monitoring app like HWinfo (dont like Ryzen Master, difficult to read imo) to keep that in check. Apply loadline calibration accordingly.

 

You can enable XMP without overclocking your CPU since it overclocks your RAM. In other words, it's a different thing to overclock.

if the system is going to be powered on 24/7 amd recommends lower than that at like 1.5v, I tend to use AI suite to overclock, and overclock when I need it to increase the life of the CPU

It will be powered on for an average of 6 hours daily. https://uk.pcpartpicker.com/user/NewVoid/saved/bZqq4D Is MSI's overclocking suite sufficient or should I use AI suite?

Just something to keep in mind, it's possible the CPU can't do 4.2Ghz on all cores. You can try it, but overclocking has no guarantee at all.

I heard people were able to go to 4.3. That made me think 4.2 was an good bet giving water cooling. But if 4.1 is all it can go it's fine as  long as nothing under that. 

 

Are you implying you can overclock cores to different speeds and run them together?

Ah I see thank you. My only fear is overclocking RAM increases CAS latency so if it is beneficial or not.

It all depends on the chip, some people can only manage 3.8 on all cores. I can just about get 4.1, but 4.15 doesn't happen (on R5 1600), so you might find that your chip won't get the performance you want.

AI suite?

Whichever works better for you, I use AI suite so that I can overclock or go back to stock quickly without having to restart and go into bios etc. Thats my personal preference

increasing CAS is fine as long as the increase in frequency is high enough.

Treat 4.1GHz for Ryzen 2nd gen as baseline. Those that can go to 4.2 are about average, those that can go to 4.3 (without going past 1.425V) are very good CPUs.

Doesn't the motherboard play a large part in that too such as the power phases ect? Also, is Ryzen Gen 2 better than Gen 1 in terms of overclocking performance?

I see. I will overclock my RAM frequency from 3000 to 3200 as that seems best for Ryzen.

 

Is the reason for different overclocking potential nothing to do with cooling but instead due to bad quality control? Also, 1.425V won't kill the lifespan too much if that is how much is being used constantly, right? I plan to keep it for 2 years.

silicon lottery, basically tiny defects on the silicon that we cannot remove or prevent completely. It's not 'bad', because those sold to you still exceed what AMD specs.

 

1.425V number is recommended by AMD to be the upper limit when overclocked
