RyZen 3000 Boost Issue: What's your take?

[Deleted member 185158]

Could use fsb to lower and tweak max mem clocks.??

My AsRock AB350M Pro4 gained bclk adjustment after bios 5.00. Granted it's only 100-103 (basically you're just locking the spread spectrum range) but hey, it's something.

That's interesting, my 450M Pro4 never got this or maybe I don't know where to look for it. What's it called in the BIOS ?

FCH BCLK or FCH Base Clock, It might hard lock during POST or in Windows though since you're also changing the clockspeed of PCIe, SATA, Nvme, and USB.

It really is hit or miss which boards have bclk. I used to think it was only the x70 boards but apparently not.

Asus ROG Strix B350-F Gaming - nope, NO bclk
Asus ROG Strix B450-F Gaming - yup, has full bclk

I know that's not much a sample size, but it's best to be sure and hopefully there are some other 450 boards out there with confirmed bclk.

That said bclk tended to make my systems get... weird since I run most of my stuff 24/7. Things like USB devices dropping after a few days, or where the machine won't ever restart correctly if you run it more than a day. Windows says "logging off" forever, which is super annoying if say a windows update 3 days ago means you've now lost 3 days of work in distributed computing.

I gained that functionality on my AB350M Pro4 with the bios update too. However, I have not noticed any abnormalities like that. Granted my memory had to be optimized for the new freq. Basically 31.33 multi to get 3200mhz.

that reminds me of the olden days when i just increased the fsb on my parents computer

My Asus ROG Strix B450-F Gaming has the BCLK setting but I personally haven't used it.
Some people said they had some luck setting it to 101, 102 or even 103 BUT it does effect every part connected to the motherboard so it can be risky.
I just didn't think the risks were worth it.
Especially since I had my Ryzen 5 2600 OC'd to 4 GHz with my 3200 MHz RAM at 3400 Mhz without touching BCLK.

Not worth it. Will brick your data drive.

For testing we followed the same setup that AMD recommended to der8auer when he did his AMD Ryzen 3000 Boost Clock Survey earlier this month. We downloaded Cinebench R15 and HWiNFO64. We then set HWiNFO64 to run with a 500ms polling rate (default is 2000ms) and ran the single-CPU benchmark in Cinebench R15. We did this three times and recorded the maximum boost clock shown on each of our Ryzen 3000 series processors.

Lastly, for those that are curious what the Cinebench R15 scores were for the Single Core CPU – we got you. You can see those results below.

@londiste
Is there something up with the firmware/AGESA version?

 

[jesdals]

Its dificult to compare across platforms and settings

I still prefer running with Pstates set at 4500mhz running it on all cores instead of PBO

Miggt try this, ty.
For now anyway.

Nope. That was the first question I had and thought might be helpful for others as well

My highest single core boost was 4.425 GHz with 4.4 GHz on a 2nd core during an R20 single core run.

I got better score with a 4.4 Ghz Max Boost:

• AMD bad marketing at it again, false advertising and lies should not be tolerated.
• AMD bad marketing alright, they need to inform consumer/media/reviewers better
• It is fine, this is fine. I am OK with AMD advertising like that because I DON'T CARE
• There should be MORE Advertising like this. Necessary evil is needed to beat Intel
• MY BLOOD IS RED! SHUT UP AND TAKE MY MONEY AMD

So My Answer to the Poll is NONE of these, If you have proper cooling and Set your BIOS up properly then it will hit the advertised boost clocks.

 

[Deleted member 185158]

Set your BIOS up properly then it will hit the advertised boost clocks.

You shouldn't have to "set up" your bios. In fact when you clear cmos or reset all defaults in bios, you should see single core boost hitting advertised clocks.

What I wonder is if changing the Memory in any way cancels single core boost. Anything changed to PBO, XFR and CPB may cancel single core boost. Any voltage settings changed, may cause loss of single core boost. Does turning off SMT cancel single core boost.

Exactly what settings should NOT be changed is my question.

 

[NoJuan999]

^ That's a valid Point.
All I'm saying is that the chip Will hit it's advertised clock by just changing a few BIOS settings.

Which bios settings specifically? I have tried so many things.

@ Nordic
I enabled PBO and set my Max PBO boost to +200 Mhz (and chose the Motherboard as the MHz limit control vs Auto or Manual) and set my Throttling Temperature from Auto to 80 (since that is the highest I have seen my CPU go while stress testing and should be safe for short periods of time).
And I have an Asus MB so I set my Performance Enhancer to Level 3 OC.
And I set Performance BIAS from Auto to None.
And I have my RAM set to 3200 MHz using the XMP profile, I have not attempted to OC it any farther yet.
I looked at a LOT of other settings But I haven't changed any of them to see if they hurt or help performance.
And just to be clear, enabling those settings increased my single core and multicore clocks and CB R15 and R20 scores.
Look here:

What's your latest tech purchase?

Did not have a lot of time to play with the RAM, this is the best I got atm: I will try this kit these days to see if I can get 3200mhz with lower timings Crucial Ballistix Sport LT BLS2K8G4D32AESCK 3200 MHz , I like this RAM as it is white and low profile and it was cheaper than the Patriot...

Your Asrock MB should have similar PBO settings BUT I have no idea what other optimization settings it has.

It's all about the firmware. That's where boost specifics are set. Early bios' hit boost but AMD has been dialing it back slightly for longevity but now ppl are bitching and moaning. They'll probably dial it back to where it was before. The newest bios' are the slowest btw. You can read about this from Shamino of Asus. He uses his personal acct here as to not whatever...

If yall want max boost run the earliest bios.

With the exception of whatever this performance enhancer setting is, I have tried all that. Setting PBO +200 actually lowers my average clock speed but doesn't increase my max boost speed.

In this thread and others we have been saying that it isn't a settings problem. AMD even admitted there is a problem.

 

[TheoneandonlyMrK]

So I got my 3800x boosting as it should to 4.5 on many cores on a crosshair VII hero bios 2703.
Initially I updated bios , swapped 2600x for 3800x cleared cmos , removed battery ,cleared cmos refit battery clr cmos then loaded optimised defaults and proceeded to find that only the core performance boost setting in the main tab did anything to gain core speeds , with it off i got 3900 , on i get 4375 max , none of the manual Pbo ,Xfr settings did anything at all regardless of other settings.

Last night i reflashed 2703(1.0.0.3.ABB) ,did a longer clr cmos , now my chip gets to 4500 on all cores using no pbo xfr just default settings, it was late at that point so I have more to try later.

 

[Hellfire]

I've managed to lower voltage and get 4400 on all cores @1.35v today on my Crosshair VIII Formula on a 3900X

This is with Asus 1001 new bios

With the exception of whatever this performance enhancer setting is, I have tried all that. Setting PBO +200 actually lowers my average clock speed but doesn't increase my max boost speed.

The performance Enhancer settings are an Asus BIOS feature to boost the PBO level.

Level 1 & 2 are using constraints recommended by AMD for silicon reliability and life span.
Level 3 & 4 are enhanced versions by the Stilt and ASUS and is basically an overclock.

Information to note when using Performance Enhancer.

With eXtended Frequency Range (XFR) version 2, there are configurable options which can increase boost frequencies and duration.
The available options are PPT, TDC and EDC under “Advanced\AMD CBS\NBIO Common Options\Precision Boost Override Configuration”.

The BIOS item “Performance Enhancer“ tunes these options in a simple way.
Level 1 and 2 rely only on the AMD provided options mentioned.
Level 3 and 4 has a few tweaks of our own (with the help from The Stilt) which causes XFR to always boost to the highest possible frequency.

When using Level 3/4, make sure to use the Balanced power profile, or adjust the “Minimum Processor State” to below 50% on your preferred profile. Otherwise, Core Performance Boost (CPB) will not work properly and single threaded performance will suffer.

Additionally there’s a grace period of roughly a minute after entering the operating system until P-states are engaged properly.
Each CPU is different and boosts to different frequencies, the same settings on two different samples will give different results.
The increased frequencies might be too high for some CPUs or require additional voltage.
When using this function, it’s best to rely on Offset Mode for the CPU Core Voltage.

I have an asrock board so that would make sense. Thanks for the information.
