Precision Boost Overdrive How Much Over Max Boost You Have

[gerardfraser]

EDIT Aug 12 2019:Let me start by saying I was wrong and I apologize for any misinformation I supplied due to my ignorance. I was aware of Third-Party Monitoring Tools not being as accurate as Ryzen Master and I just ignored that fact all together.

I have started testing with Ryzen Master only now to see what the actual clocks on my Ryzen 3600X really is.Although I still get over Max Boost as what is written on the box so I have no recourse to complain to AMD or refund my CPU'S.Also they are still fast little CPU's Still happy.

I have only witness Cinebench20 hitting Max Boost on 2 cores as of testing today.I will test some more with different BIOS and if any change is observed I will post back.

Spoiler

Updates to Precision Boost Overdrive Override for the AMD Ryzen 3000 Series can give an addition 200Mhz added to what is printed on the box.

So I was wondering how much over max boost can you get on a Ryzen 3xxx CPU and did AMD LIE lol.

Motherboard MSI X470 Gaming Plus + 3600X
Max Override Boost 182.1Mhz on 1-6 of 12 cores for total up to 4582.1Mhz.

Anyone have any luck going over max boost clock.

Guess my 3600X is getting like that AMD fine wine treatment with age:Boost now up to 4580Mhz.

OP, i think you make me regret getting the 3600. I'd lucky to see 4.4GHz.

I bought 2 X 3600X and one still did not arrive yet .I did not buy the 3600 because I did not think it would be able to hit 4400Mhz.
I got the 3600X thinking I could get 4500Mhz with a chance but not likely 4600Mhz on at least one core,so now i have some hope on the 4600Mhz boost with improved BIOS but as humbug said I may be at max with 4525Mhz.
Anyway 4525Mhz on 4-6 cores while gaming and light loads is great and I will take that without regret over the extra cost for the 3600X.Another Bouns got my X470 with ebay deal 20% off so it cost me a tenner for the motherboard.AMD win win win.

[gerardfraser]

Well you guys just have crap BIOS and should be better when a proper BIOS is released.I can say I showed videos boosting past what's written on the box.

It is still useless yes, but I want what I paid for ,simple as that.Do not settle for crap BIOS and contact AMD/Motherboard manufactures.

I see people settling for 4200Mhz on there expensive 3900X,I would be ******.

 

[gerardfraser]

Sounds like a plan.My Ryzen system has been rock solid with MSI Motherboard.AMD has the new BIOS going out to people.Maybe soon it will be corrected for everyone.Good luck.

 

[gerardfraser]

Regularly see 4.525 and 4.550 on my 3800X, obviously in very short bursts.

Really?? That's awfully high. Higher infact than AMDs stated "MAX". That no one really actually gets.

Well I would not be satisifed if I was either one of you guys.Both your CPU are underperforming but there will be a fix from AMD someday.
Mine 3600X does 4525Mhz like in the videos posted.I am satisfied.Forgot smiley face

Ryzen 7 3800X -4500 Max Boost on the box + up to 200Mhz=4700Mhz
Ryzen 7 3700X -4400 Max Boost on the box + up to 200Mhz=4600Mhz
Ryzen 7 3600X -4400 Max Boost on the box + up to 200Mhz=4600Mhz

I haven't added any boost overclock yet - but I think I'll have a go. Is that literally all you did was enable the over ride and add the numbers? Why only 125Mhz and not 200Mhz? Or was 200Mhz not stable?

This is a question I still need answered. Why not just add +200?

Well my Motherboard I can select up to 500Mhz and several modes of automatic overclocking by AMD algorithms which do everything 100% stable.

EG: This screenshot is with
Enhanced Mode 4 in BIOS
AGESA AMD ComboPI1.0.0.3
AMD Ryzen™ Power Saver Plan
5 CCX Boosted to 4400Mhz
1 CCX Boosted to 4450Mhz and all cores boosted above max boost written on the box of 4400Mhz.This applies to Light loads/90% games/Cinebench single test with boost to 4525Mhz

Results


BIOS selections modes

Nah, don't you worry I'm very satisfied. I know my CPU is performing fine and inline with 99% of people's 3700ks.

4.6ghz stock is not a realistic goal. Basically noo is getting that so don't be daft.

Interesting you can be satisfied all you want.

You can set it to whatever you want really,as far as I understand. It is a form of overclocking which can disable/bypass limits and can void warranty like anything else .

Precision Boost Overdrive/Precision Boost 2/Max CPU Boost Override allows an AMD Ryzen processor algorithm to increase clock speeds and voltages when the CPU has electrical, thermal, and/or utilization headroom to spare and can/will boost to maximum overclock for the CPU. In other words: if the processor’s analysis of its own environment indicates that it can safely go faster, it can/will ,also there is always safeguards in place.
Each CPU of 3xxx has a hard limit but Actual BIOS revisions/Chipset Drivers and AMD /Microsoft power plans have an influence on how much voltage and clock boost there can/will be for the CPU.

With 3600X both hit a limit of Max boost of 4525Mhz and not full 4600Mhz which is 4400Mhz on the box + 125Mhz,maybe if a had a better Motherboard/cooling my max could be higher up to 4600Mhz. Hope this help ,I could have copied the AMD stuff but I just wrote what I thought how it works.

As far as I understand the maximum 1:1 ration of memory to IF is up to 3733MHz (may be 3800MHz). However after this value the IF switches to a 1:2 divider so you can configure your ram higher but your IF is halved.

Depends on CPU up to 1900Mhz(3800Mhz)
After that point Memory clock / Infinity Fabric /Memory Controller will work 1:1:2
EG:
2100(4200Mhz) memory Clock
1900(3800Mhz)Infinity Fabric
1049(2100Mhz)Memory Controller

This article from GN delivers a pretty damning and detailed review on the effectiveness of PBO and Auto OC.

TL;DR: it doesn't really do anything to improve performance over stock configuration.

What the hell do you mean useless.I got 1 FPS more on Shadow of the Tomb Raider.Anyway the thing is most people do not know it is useless but still want 5.0Ghz on AMD even though 4.2 Can beat just about any Intel CPU in productivity and since I only game and at 4K the Ryzen CPU does just fine.

 

[gerardfraser]

NO no no no no I am the only one in the world where it works as it should Jacky60 is correct.I am special and all you other buggers are drinking Koolaid.
Thanks Jacky60 your a reasonable voice among so few people out there,you have a firm grip on reality.

 

[gerardfraser]

If I want to run at a certain clock speed.No voltage would limit me,especially when you have a warranty ,how the hell would anyone know.
Just saying but 3600/3600X are lower binned parts and most people will need 1.35v which is fine and would last for 5 years easy.

Thanks for the detailed info. You really have a nice chip.

Well no problem at all.This is not directed at you,just letting people know who are hung up on the numbers.

I only play games all day,hence the Cheap X470 and 3600X.As far as the way I game and this covers 98% of all games
I game 3440x1440 and 4K and Ram speed does not make a real difference or boost clock.With Ryzen people do not need the highest number the chip can do.AMD overclocking is fine for gaming.
I also tested 4250Mhz-4500Mhz all core overclock and Memory 2133Mhz-4200Mhz and the results were the same in gaming all around with no notable difference perceived by me.

 

[gerardfraser]

Tried loads of settings and I cant get my 3800X above 69W. Even Grif above gets 90W from his 3700X

Did you actually go into BIOS and set manual limits past 69W,just asking.

 

[gerardfraser]

He is not boosting to 4500Mhz on multi in any cinebench,it can only be done on single.I say he is in the range 4250Mhz give or take a little .I am sure he just does not know how it works.

 

[gerardfraser]

Nothing would go pop if it had not already,it is your motherboard/cpu and if you want more out of it,change settings and try.My CPU boost to almost 200mhz written on the box and so can yours.If BIOS permits.

 

[gerardfraser]

Unfortunately for me, I think you are correct. I'll get my dunce hat.

If there are any Ryzen 3000 Spacktard guides around I'd love to read one

No it is new and everyone is a dunce just about with Ryzen stuff. The best performance is pretty much what AMD has done and that is a very good thing.As Lolik says manual usually results in lower scores over AMD algorithm where boost is involved with there own overclocking,do not worry about the higher numbers or matching intel 5.0Ghz number when a Ryzen can be faster at 4250Mhz than a 9900K @ 5200Mhz.Now to the nutbars this statement above will not be accurate for 100% of all situations ever in the world.
