Overclocking Basics

[Hold-Ma-Beer]

I am a first timer when it comes to overclocking (or anything related to desktop, its my first build :P). My specs:

Ryzen 3 2200G

Gigabyte B450 Aorus M (Gives me real pain while ocing)

Corsair Vengeance (3000MHz XMP)

Corsair CX450W

 

I'm confused as to how to set voltages when overclocking? Like should I just go to the max recommended VCORE (1.4V) and try increasing clocks or the other way around?

Also how to find the best SOC voltage when overclocking the iGPU as well?

I'm a complete Noob.

Thanks

As a general rule of thumb, overclocking means increasing the clocks, until you find the maximum clock rate the CPU is still stable at.

 

Increasing the voltage can help with stability, but it will also increase power draw and heat output, so you shouldn't do it unless you have to. If you go too far it can shorten the lifespan of the chip.

 

I think for Ryzen most people just stick to PBO, since it'll get you most of the way there without any manual tweaking.

PBO??

Precision Boost Overdrive, essentially an auto-overclock for the CPU. https://en.wikichip.org/wiki/amd/pbo

I agree that manually overclocking the CPU wont give any groundbreaking performance increase, but the iGPU can for me

Agreed.

In my case, I have to. I'd like to learn how to overclock and that is why I went with AMD. So like should I start with stock 1.3V and increase clocks and if system is unstable, increase voltage? And when stress testing, should I push the iGPU too?

I would overclock them individually. Otherwise, if you overclock both at once and your system crashes you don't know which one caused it.

 

For example, you could start with the CPU. Keep raising clocks in small increments and do some stability testing in between until the system is no longer stable. Then either dial it back a little or increase voltage in the hope of making it stable again. Rinse and repeat. Once you're happy with the CPU, do the same for the iGPU.

 

I would suggest to use a combination of multiple load tests and/or games to test stability. E.g. on my system I've had GPU undervolts that ran perfectly fine in game A, but kept crashing consistently in game B.

 

All of that depends on what your goal is. E.g. for my own system (older i5) I've raised clocks only slightly and then lowered voltages as much as possible. This way I get some additional performance combined with better thermals and lower power consumption. For my GPU I've mostly gone with undervolting since it is factory overclocked already.

 

Just to point out: The advantage of PBO is that it is much less work, has mostly the same effect and can overclock individual cores based on their capabilities.

@Eigenvektor Thank you for the comprehensive explanation

Also should I set the SOC voltage where other people have found their system stable? Like in many online forums and videos, people have found 1.2V for stable overclocking.. Because I don't know how to set the right SOC..

This motherboard only allows offset voltage adjustments.

 

You can use Ryzen master, but its more of a pain because it doesn't load at startup with your of settings.

 

I have mine set to +0.156 and it generally seems to run at around 1.38v.

[Hold-Ma-Beer]

@Mister Woof Thank you mate. What bout the SOC?

I don't remember - I haven't fiddled with it since I got it stable. Pretty sure you can set that static. But I'd have to check.

 

I'll say that first generation Ryzen can take more voltage than second and third. Don't go as high as I have on the vcore, and iirc don't go above 1.2v for SoC.

[MpNkpz]

X570e still but I found soc only scales up to about 1.019. To go more is definitely hot when I start increasing frequency or touching up how much vDIMM frequencies I would like to post one day

All the other forums and videos I've seen for overclocking a 2200G have said to set SOC at .12 for best stable results, so I'll go with that

[Hold-Ma-Beer]

Fk....

I tried starting my pc at 3.725GHz at 1.3V, it started and crashed. Then forced restarted it, made it to desktop and crashed. Went to bios, set everything to default, windows startup repair appears. Then electricity goes out in the middle of that

@Eigenvektor and @Mister Woof

I was able to overclock the CPU (Ryzen 3 2200G) @ 3.9 GHZ stable at 1.3125V. Should I up the voltage and push more?

This was on Ryzen master. It would be a total nightmare setting this voltage in the BIOS offset shit..

 

Edit:

Went ahead and pushed the CPU to 4.0GHz at 1.375V stable. what should I do??

I'm currently trying to push a little further so I can then downclock to 4GHz (4 looks way better than 3.9 )

@TofuHaroto Sorry to disturb, your thoughts?

No worries.

Well reading through this. 

For the soc. Don't go over 1.2. As for voltage. This is zen + so it can handle higher voltages. I'm going to assume that's 1.375 with an offset. If it's static remove it or just downclock to 3.9 as the voltages are way more reasonable. 

One thing is that ryzen is pretty maxed out, out of the box. So it doesn't have a big overclock headroom. Enabling pbo will save you a lot of hassle unless you it's fun for you. 

[Hold-Ma-Beer]

@TofuHaroto Help me mate!

So see this: At 3.9GHz stable with 1.3125V (on Ryzen master) my motherboard(CPU-Z and HW monitor) reports 1.278V (max)

 

Went to the bios, set Dynamic vcore = Auto ; the softwares report 1.356V (max)

 

So now, should I set the dynamic vcore = -ve something?

I would just out DVID to auto.

I would trust hwinfo64 on this reading.

i am not certain on safe voltages for 2nd generation Ryzen. Look it up - i know 3rd gen doesn't tolerate as high as voltage as first gen.

 

Also, I would not trust the sensors with 100% accuracy. I would assume your voltages are somewhat higher than reported. Many tech outlets have investigated sensors and often they are under reporting values.

 

EDIT Oh, forgot. It's 2200g so its first gen. Should be okay with that voltage (if that's indeed true reading)

Yes indeed. They are reporting a 1.3125V (set by Ryzen Master) as 1.278V... So yes these are shit.

But when I was testing these settings, I had idle temps around 35-45C and load temps around 66-70C.. When set Dynamic Vcore to auto in  BIOS,

idle temps 50-57C and load temps 73-80C !!!  The motherboard now reports 1.380V.

Seeing how it reported 1.3125 as 1.280... I'm worried that my CPU is getting much higher voltages when it really doesn't need it

 

Edit: Just noticed that Idle temps are jumping like every second (48,55,57,46 so on)

I mean you can play around with dvid if you want. But I usually would recommend to keep it set to Auto.

Hwinfo64 is probably pretty accurate. Though both of these aren't completely accurate.  

[Hold-Ma-Beer]

@TofuHaroto Ok, I'll try to lower the reported Vcore values, since my PC is running way hotter than when I was stress testing it earlier with Ryzen master..

[Hold-Ma-Beer]

@TofuHaroto Did -0.072V on Dynamic Vcore and now it reports 1.308V max as compared to 1.380V earlier.

So it might be closer to the 1.3125V I initially intended to set :)

Now idle temps are in 40-45C without those awkward jumps and full load temps are below 75C

 

Also, I ran Cinebench to check system stability and got my highest ever scores!

Multicore: 1501

Single core: 400

Thank you everyone! I'll be back for overclocking the iGPU when I receive the new cooler :3

[Hold-Ma-Beer]

@TofuHaroto Sorry man but my problems keep on popping up..

Now, when I shut down my PC and turn it on again, the CPU gets locked to 3693MHz!! I restarted to check in the BIOS and it was set to 3.9GHz!

 WTf is going on?

Could be an unstable overclock or just a crappy bios. Is it up to date? 

Generally if manually overclocking is a pain just enable pbo. And it'll do the same thing.

X570e-gaming, 3800x 4.275ghz, 2080ti, 4X8 g. Skill 3200 16 cjr, 750w ps. My question what's the best way to adjust voltages if the cldo and vddg don't work on auto when I change to these 3466hz: 16 18 19 trp19 tras36 Trc57-8 (4,6-6,8) tfaw(34,20,36) twtrs4,12 twr(12,10,13,14)scl4(520-550) tcwl16 trtp(10,8,12,13,14) trdwrtwrrd(7,3-8,3-6,3?) don't need tertiary auto those. ODT40-53.6ohm bus24202024(yields the most variants on boot code error) I'm mostly unsure about using rcdwr19 trp19 ras38 trc 60 and tcwl14 and twrrd 4. Why it's not tWR 14 maybe my trcdwr won't allow the heat to dissipate?
