5950x 90 Degree Under Load?

Right-o, here we go, screenshot dump incoming!

Extreme Tweaker has one reference to PBO - Enabled


View attachment 25855

Expanding confirms this is now set to enabled (under volting removed from manual menu entry)

View attachment 25859




Advanced has another reference to PBO - also set to enabled

RM now shows as default (initial launch still shows PTT, but a quick 'reset' from the lower left menu in RM changes this).

Also, all the Asus rubbish has now been removed.

Oh my goodness I can't look at that monitor without shedding a tear - it's so beautiful!

So everything under both menu sections for PBO in BIOS should be set to AUTO - not Enabled. Including the Fmax Enhancer. So everything to AUTO everywhere its says PBO basically.

When you reboot then, RM should show default without having to do anything to it.

Could you also get a shot while you're in there of the Extreme Tweaker page items above 'CPU Core Ratio'? (Really, I just want to see another shot of your monitor..... )

When you applied the Undervolt how did you do it? Was it on a CPU Core Voltage Offset on the Tweaker Page? Or through PBO Curves Optimiser under the Advanced Menu? Or VDDCR Voltage Control?

Just a little something to keep you entertained whilst I see to a few bits before I crack on with your excellent advice, thank you!

Just about to take a quick look at this, I'll bow to your knowledge in this area, my understanding was that auto doesn't necessarily mean enabled, are we doing this to roll back to default settings?

The undervolting was done through the PBO Curves Optimiser, under the advanced menu

'Auto' will allow PBO to operate within the Ryzen default limits for PPT, EDC and TDC. 'Enabled' sets these limits to the Motherboards max - which is where started sort of!

If you used Curve Optimiser for the undervolt - and have disabled that undervolt before returning PBO to Auto then it's gone. If you leave don't undo the Undervolt before you set PBO back to enabled or auto then the Undervolt actually remains in place - you just can't see it.

Despite all that there is still something strange going on that is limiting the power to your CPU - so we need to get al those settings back to standard values before we can move on and see what's what!

That makes perfect sense, I’ve undone the under volting now too, settings shown below also, which does match the RAM specification

Forgot to say, plan is on AMD Ryzen Balanced

OK - thats great - so I think we may have found the missing link. Core Performance Boost should be set to Enabled - or AUTO if the option is there - but I think it will just be 'Enabled'.

That will allow the processor to boost within whatever headroom is avaible up to the limits of the default PPT and so on. With that disabled the CPU is tied up and restricted to it's Base Clock speed only.

With Core Performance Boost Enabled - and all PBO options back to AUTO - you should see 3.9 GHz all core boosts and 5 GHz single core.

It should be drawing almost 140W at full load also - and I'd guess given your other numbers above - about 70-75 degrees.

Fingers crossed that's it!!!

Ah, it was going so well! Made the changes above, opened up RM and enabled overdrive, back up to almost touching the limit:

OK - RM can be a pain - set it back to default within RM there and try again.....

 

[mossmotorsport]

Will have another play tomorrow. Thanks ever so much for your help today.

 

[NoddyPirate]

No worries.

If you enable OverDrive within RM you are bascially over riding all the BIOS settings you have just made - so you don't want to do that!

What we need to is get your CPU operating back within default power limits, but with the ability to boost and use up all it's default headroom. We don't want to enable OverDrive manually at all - just allow it to boost by itself with it's own parameters.

You are one click away from confirming it! Enable Default in RM and it should behave itself.....

Final thing for the evening - the Ryzen Balanced Power Plan was apparently removed for the 5000 Series CPU's with the latest chipset drivers. I don't have it as an option on my CPU.

So might be worth double checking that you have the up to date chipset drivers installed too.

Thanks, I grabbed the latest drivers from the AMD site but I’ll uninstall and review tomorrow. I also heard that this power option is unnecessary for these chips, as Windows now has built in Ryzen power refinement options.

Yep - the standard Windows Power Plans work fine with it.

Good luck sir! And fingers crossed it'll behave tomorrow. Let us know how it goes.

Remember to return RM back to default before your next attempt though - it may ask for a restart - if it doesn't perform one anyway - and during that restart go back through BIOS and make sure all settings are still as above. It's hard to keep up so a quick summary:

BIOS:

Core Performance Boost - Enabled
All PBO Options - Auto

After Boot up - leave Ryzen Master in it's Default mode - which will simply follow whatever BIOS told it to do during the boot up! Don't change the Ryzen Master mode at all......

Just to add for your @mossmotorsport - Here's what I see in HWInfo and RM when single core boosting - RM just doesn't see my boosts properly on single core loads.

HWInfo catches them - but also gives you the 'Frequency Limit - Global' which is the upper limit set by the CPU for any core at any time. This is a handy reference value for multi-core boosts too as it will show what your cores are targeting......

Here's RM during a single core load using Cinebench:

And here's HWInfo taken during the same boost:

Cheers @NoddyPirate

I think we're back in business! Temps are looking fine now under load, within Cinebench R23 and Time Spy. I'm not entirely sure it's boosting to as high frequency as I've seen previously, but I'm sure in real-world use it wouldn't be noticeable.

Thank you for your help, it's been a blast!

Great news @mossmotorsport ! Fingers crossed all behaves from here out.

As above you can check HWInfo for the actual achieved boosts as it’s more reliable.

Any other issues just come back and let us know.

If you want to play with PBO further later there is a guide in the OverClocking section here - my main bit of advice would be to just take control of PPT, EDC, and TDC values yourself - up them a little bit at time and see how the system reacts before adding more. 👍

Good luck sir!

Thank you for the feature, I'm very honoured! After years of moving about on my chair sadly the carpet has seen better days! And don't worry it's something that bugs me too 😂 Been thinking about getting my PC on something, even if it's just some MDF cut down from Wickes 😂 Or maybe I make...

And well deserved! I’ve enjoyed this thread just for the pics alone! 😍

 

[NoddyPirate]

@mossmotorsport - sorry - final thought - you can force stock behaviour the crude way if you were inclined - and also give yourself a starting point for PBO tweaking - by enabling PBO in RM - or in BIOS - and entering the following values manually:

PPT - 142
TDC - 95
EDC - 140

That will force full boosting - but with the standard default limits for Ryzen 105W TDP Chips - which is the way it should behave out of the box.

Whey!! It’ll need an update once the HM Logitech Embody arrives 🤣

I’m living off of baked beans from now on, spree finished!
