5800X Boost set to 5050Mhz all cores with AMD Curve Optimizer

[gerardfraser]

OK I will try to help a little but all I can do is show stuff,not for me to interrupt results for anyone.I do not know anything about this stuff until AMD releases more information and fixes what they said on Nov 6 2020. Take anything with grain of salt.

See Post #62 in this thread for what AMD said.

As far as I know CPU Core offset voltage does not work on the MSI X570 Tomahawk ,it should give you the base clock of the 5800X CPU if you change this. Now CPU override voltage works but will involve clock stretch in negative voltage is set(See Post #62 in this thread for what AMD said).

F these terms can get confusing ,so I am not sure which voltage some of you are speaking of when you say things like is vcore offset required and vcore offset is fine.

@Rom you posted CPU-Z shots of all core clocks. Not sure why but I did quick test,only tested for a few seconds each after windows loaded around a minute or two.Also take note of effective clock speed

 

[gerardfraser]

One thing I am struggling to understand is that my multi core score is higher if I set a manual voltage of 1.35v but my single core score is lower but if I set it to auto voltage my multi score is lower and single core faster

Yes this is how it works.Read below what I am going to say,it may help or not.

I can confirm this is correct for the MSI MEG Unfiy X570 too. I set the offset voltage to + 0.037v and max boost was 3.8Ghz.

Gone back to boring auto settings until I can understand the Ryzen overclocking a bit more.

@gerardfraser thank you for taking the time to test that!

I only used it as its quick and easy, was just a way for me to get a 'score' to compare after changes, rather than waiting for R20 etc which took ages for SC compared. Probably not as good I know, but if Im honest, this isnt an area I want to spec hours playing around.

Im a very basic OC'er, usually just find a guide for my cpu and copy it. Im probably best off waiting until there is better data out there. Really appreciate your posts, they are just a bit over my head

If im reading it correctly, we are undervolting by using negative curve? But expecting it to run higher boost?
Could it be that some cpus, will need more voltage, not less? IE my 6700k needed 1.4v to be stable at 4.5, many others were stable at 4.6 with only 1.35v etc.

The Ryzen CPU works different than an Intel CPU and Intel will /is/are shifting to AMD Ryzen way of running there CPU's now or at least very similar,not that it matters.

Auto setting work great on Ryzen CPU's and they are for 98% of the people with Ryzen. Only people who want to tinker with Ryzen and may have a little benefit at all are people who do actual work on computer to make money and use a specific program to do this. Then overclocking for high single core or overclocking for high multicore overclock is beneficial to them and there work projects and is needed.

Then you have actual overclockers trying to improve the size of there epeen or evag to impress others. These guys will do anything possible to get 0.1% better score on a benchmark whatever it takes.

As I said and is only my opinion 98% of people should just run on auto and let the AMD CPU algorithm do it's thing and you get the best of both worlds. Great single core performance and Multi core performance especially on any AMD Ryzen 5000 CPU.
I fall within the 98% of people but since AMD can offer some more perceived performance over a wide variety of use's than I jumped on it an made a thread.

Now the perceived performance I am talking about and is pretty much useless in everyday normal things is getting a higher Cinebench20 score in single/multi core.This has no use in anything unless you actually are a Cinema 3d artist which goes back to the work thing above.

Having a AMD Ryzen CPU set to 4500Mhz is not going to effect PC gaming or anything you do compared to having the highest single /multicore in Cinebench at say 5100Mhz. Maybe it may effect low resolution PC gaming but I have not tested it yet on Ryzen 5000 but I have on Ryzen 3000 and made no real difference. Who really buys $1000 GPU/$700 CPU and plays games at 1080p.

Best part is this is easily testable. I am trying to help out so in your mind like mine, I love seeing higher numbers but reality is it makes no difference in the real world.I am not trying to be mean and I said this before in this thread.
I can share so things I done for myself to me me feel good and I even know there is no difference but I also like higher numbers. On every Ryzen CPU I owned 2600x/3600X/3600XT/3800X/3800Xt/5800X I was able to achieve what I want and shared the information at times to where I get people calling me a POS,Liar I could go on.

Last thing do not worry about your scores if you can not get them like someone else that is fine and running AMD Ryzen at default is fine also.Adds needed smily face to show not serious guy here

 

[gerardfraser]

Yeah, getting this as well on the Unify. Also want to clarify in my previous post that setting all cores to -5 curve is actually stable for me, but setting any number more than that isn't.

This may be the same across all motherboards and AMD Ryzen 5000 CPU's until AMD releases the BIOS update to handle this better with AMD Curve Optimizer ,all I know when I am PC gaming and look up and see 5000+ Mhz,it works good enough for me. It's overclocking everyones CPU may react a little different.Also AMD hits the magic 5000Mhz wall yeah that is good enough but how far to they let the CPU go till,there has to be a limit some where with regular CPU cooling ,I see 6000+Mhz with LN2 and alike.

As for the voltage offset I believed Robert Hallock when he said that it does not work on Ryzen 5000 yet and they are making it better. At least that is the way I read his statement and when I tried it did not work.

I completely get that, but also know this is a forum of 'overclockers' as your audience... people who want the epeen for no.1 score, want 2fps faster in a game played in a resolution from 2002 or just want to learn a few new things.
It's all new stuff to me so i would say i'm a mix of all of the above with epeen being the smallest factor ( )

So true and funny as hell,I am in the same boat,I do not know jack about AMD CPU's or least that is what I been told many times. I also been told I got golden samples of CPU's many time which is not true. I press key on a keyboard until it works as I want it to,that is all not trying to trick anyone.You will get it,it is no different than any other computer after a bit.

 

[gerardfraser]

LOL nothing like jumping into the fire with some new AMD gear. The AMD 5xxx CPu's are good and interesting to play with

 

[gerardfraser]

Gerard how are you boosting to 5100+ ? I got my 5800X today and have a fiddle with PBO and curve optimiser, i can set +200Mhz offset but have to keep the voltage offset at 0, no biggy. 200 is the maximum i can select on an X570 Tomahawk, whats the secret to going above 5050Mhz?

I have posted it in this thread already.Here it is again enjoy. 5800X boost out of box 4850Mhz any PBO on can pass 4850Mhz up to the limit of whatever motherboard you have.

You can set whatever you want and check stability. First off there are two different areas in all BIOS for PBO stuff.

In the AMD overclocking section ,go to PBO and set your AMD curve optimizer up- this will give you normal boost clock EG:5800X boost to 4850Mhz
In this section you can add up to 200Mhz it is the same for all motherboards EG: 4850Mhz+200Mhz=5050Mhz

If you want higher CPU boost clocks then you need to goto the second area for PBO settings
Advanced CPU Configuration set your PBO boost higher than 200Mhz like in the first section on MSI motherboards you can go as high as 500Mhz

To get 5100Mhz then set PBO here to 250Mhz
So 4850Mhz+250Mhz= 5100Mhz
save and test.

Interesting findings from another forum. Setting EDC in PBO limits manually to 205 increases Cinebench scores. The thread was about the 5950x, but I tried it on my 5800x and indeed my MC score increased by 65 points to 6091. What was interesting, however, was that it hit my cpu-z Multithreaded score by ~90 points. Cinebench showed higher effective frequency and temp than with PBO limits set to auto, yet cpu-z was lower effective clocks and temps. With that, I don't know which setting translates more to real-world performance, particularly in gaming, but something to think about. The user also mentioned lowering their CCD/IOD voltage from 1.05 to 1.0 increased their CB scores, but doing that lowered mine.

CPU-z with auto pbo limits https://valid.x86.fr/mr5iz3

CPU-z with EDC limit set to 205 https://valid.x86.fr/revj1j

Well fellow Canadian why not use the EDC bug for even higher clocks. Set EDC to 1 PPT/TDC to whatever you want. OF course you will have to test with PSS on/of Cstates on/off for best results on AMD Ryzen 5000

On my ASUS X570-Plus there is no Curve Optimiser. In AMD Overclocking/PBO it shows the same options as in your screenshot but no Curve Optimiser.
Then under AI Tweaking/PBO it shows the same options again.

I think people get confused because the PBO has same settings in two different areas.

Might just try the first PBO setting change later.

There was always two different areas for PBO and it should confuse people at first but like anything they will get use to it. It does not mater which area you use they both work.

 

[gerardfraser]

Maybe a stupid queston @gerardfraser , but are you setting override voltage or leaving it on auto? With auto and PBO on auto without changing any settings the max core VID i'm seeing on my 5800X is 1.488 V recorded in HWiNFO64. That seems rather high to me. Max Vcore 1.462 V
Max CPU temp is 81c running Cinebench R20

Those are normal default voltages and are not high AMD Ryzen works like this,light loads high safe CPU voltages and highest boost. Heavy loads AMD Ryzen algorithm adjust CPU to keep the electrical, thermal, and/or utilization headroom under control and within safe parameters

Could you share the link to that discussion?

It is Elmor Labs take on AMD Curve Optimizer thread and schoenzy is referring to the guy that is talking about making changes to PPT/TDC/EDC just normal things and post in particular he is talking about is #73

[gerardfraser]

Thanks - makes sense. Areeeeee, I see your single core boost is to 5050Mhz, not 5050Mhz on all cores!!

You are confusing me. This is exactly how the AMD Ryzen CPU is supposed to work. I set AMD Curve OPtimizer to boost to 5050Mhz on any core when boost,it is not supposed to be all at the same time. That is a different form of overclocking and has nothing to do with this thread.

Nope, all core hits around 1.325v VID when all cores loaded at 4.5Ghz

Although AMD 5000 CPU's are a little different on voltages from previous AMD Ryzen CPU's UK_SPAWN is correct the Ryzen CPU voltage range at default is 0.200v-1.5v and depending on PBO and agesa BIOS can go up to 1.55v

I am not trying to say anything here if you want ,I suggest maybe check out some more Ryzen stuff and get more familiar with Ryzen the way it works. It may or may not help but you already have the fastest CPU out of the box if you just let it do its own thing with boosting and running.

Like I said in this thread a few times,if you like big numbers then a thread like this is good, there is no real gains in performance from default and you even mention it in the above post.The AMD Ryzen CPU is still as fast as any Intel CPU @ 5300Mhzin PC gaming/applications. Do not sweat the littles things that do not mean crap and is all in your head with having the absolute best score in everything,your not missing a thing with your AMD Ryzen setup.

Leave it default and enjoy your CPU

 

[gerardfraser]

Sorry if i confused you. I confused myself as thought it was 5050Mhz all core (all at the same time) boost. I now know I just read it wrong.
Thanks

No it is OK ,just had to read it a few times,I am not that swift to get it first time.

Yeah we hear you and yes I will probably leave it at default but you can't dangle an overclock suggestion such as this over our heads and then say dont swet it when we give it a try and it doesnt happen on our kit !

Altering the PBO settings like you suggested on my M/B did sweet franny adams apart from it lowered the CPU vcore which is really weird and not what I expected. So its not quite as straightforward on my M/B as it is with yours. It would be nice to see if I could get a similiar result, simply because I can (thats what overclocking is all about) but even if I did manage over 5ghz on one of the cores I would probably change it back to default anyway for the long term.

I've ordered a 240mm AIO so I might have another play (because I can) when I've fitted it.

LOL I made the thread to let people know what is possible, so everyone can try. If they do not get it or their motherboard does not want to do it then default is perfectly fine in my opinion.

It is overclocking after all fun to play with.

 

[gerardfraser]

Ram has no effect in Cinebench but you can always set 2133Mhz and test

 

[gerardfraser]

You could always put your ram to 2133Mhz for a day and then you would know for sure.

 

[gerardfraser]

According to Custom PC Mag when they benched the 5xxx series the speed of RAM did make a difference. I am running 3000mhz and Guest2 is running 3600mhz so that may make sense why his results in Cinebench R20 are higher than mine ?

Great thing about the internet you can always find what your looking for. Let me go another step further and blow your mind. AMD Ryzen FCLK speed is a myth. Tune your ram best as you can and there is no real performance difference same as in Cinebench ,now I can not say all applications because I did not test every one.

I could fill up the thread with lots of benches I did but no point really.Well here is one for fun in PC games.
The reason why I say this,I see people going out and buying expensive ram for no real gains.If you have a specific need for faster ram ,then I am no ram destroyer ,just sharing an opinion. I am an idiot,I have no less than 6 different Ryzen CPU's ,4/5 sets of ram/10+ gpus/NVME/SSD/Hard drives . I like playing with gear and playing PC games.

Well I only use auto voltages for all settings when I am posting anything related to PBO,AMD Curve Optimize even all core overclocks. LLC is all auto everything auto except on all core overclock I have to change CPU voltage to 1.3v for 4800Mhz.

Yes I agree with you about some motherboards overvolting on AMD CPU 5800X but some people use the same motherboard and still overheat. I am going to assume you responded to the thread in Techpowerup on the two video I show voltages and Temperatures. I have no problem testing on minimum at all and I would only get lower temperatures but currently testing a set of Ram for errors for someone. It is at 1 hour in the test and I usually do the test for 10 hours ,then it is Saturday I have begun drinking some beers and after the 10hr test,this fat cat will be too drunk to test minimums . So I say it would be tomorrow evening at minimum before I could do the test.For now three video all auto voltages,no LLC with Hwinfoinfo64 on.

4800Mhz all core CPU voltage- 1.29v Temperature- 72.5 ℃ HWinfo64 on and all voltages auto except CPU voltage- 1.29v

Spoiler

Effective Clock 5800X at 5100 Settings voltages are all auto voltages and on low side by the looks of it.

Spoiler

AMD 5800X 5050Mhz AMD Curve Optimizer Cinebench R23 -This ran for 30 minutes and hit 79.8 ℃ all auto voltages

Spoiler

 

[gerardfraser]

Of course but remember a few pages back where I showed clock stretching like this. Post #90 but try it anyway to test yourself.

 

[gerardfraser]

No clock stretching is reporting high CPU clocks with less performance than default. Clock stretching tricks the user into thinking they have that big shinny number but in reality get less performance overall.
Default clocks on AMD Ryzen is up to 1.5v. You can run at lower voltage 1.2v but you must test your CPU for clock stretching, just make sure you have same performance as default voltage and prefer more performance than default voltage.

 

[gerardfraser]

AMD CPU's are good first post in thread has this video
All Core 4750Mhz and 5100Mhz single. If I change the setting to 5200Mhz it would be all core 4850Mhz and 5200 single, still testing for stability.It may never be be stable at 5200Mhz but that is what I am going for 100% stability and it will take a month to find out for sure.I say keep playing with your 5800X.

 

[gerardfraser]

Post #62 in this thread I posted some information from AMD ,in that post,I know it is hard to follow these things ,I have pointed it out a few times and on the screen says TJ Max Temperatures

 

[gerardfraser]

EDIT: Forgot to mention in post #62 it is stated with new under volting stuff,it will be called with curve optimizer should be awesome for reducing temperatures but who knows
AMD Adaptive Undervolting
Yes that is a correct score @4750Mhz all core overclock with real time priority set for cinebench. Now I am not trying to be mean, you can judge your CPU performance by that all you want. You will get a handle on how Ryzen CPU works ,I can not keep repeating myself every few post.

 

[gerardfraser]

Testing 5175Mhz now

 

[gerardfraser]

Well I only have 5800X,half of the 5950X. Hope the replacement is better,5950X should hit 5150Mhz boost in light loads.
