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

[Orthopod]

I thought you couldn't SLI any of the new AMD GPUs?

 

[gerardfraser]

Very interesting, thanks. What scale is the magnitude? Does 15 represent 0.15 v or 15%?

Sorry I do not know and I did quick google search and not much information on the AMD Curve Optimizer.
I know it is a voltage curve,you can set it to have better sustained boost clocks. It has set limit for AMD 5000 CPU's so 200Mhz over normal boost clock on CPU. 5800X boost to 4850Mhz + 200Mhz= 5050Mhz.

Setting PBO boost can net higher CPU clocks but not sustained like with AMD Curve Optimizer.
I am fine with up to 5050Mhz while PC gaming.The actual clock speed really does not make a difference in performance but if you like seeing over 5000Mhz then it works.

Thanks! I'll give it a try. I'm interested in the same or better performance for less voltage definitely.

Here some information from elmor labs and what he thinks it is.

AMD Curve Optimizer?

Is this a software thing or an Agesa thing? Available to the 3000 series?

Great Find. Attached to a reddit post i started about another post in here! Great Performance. AMD left us a great gift to play with!

BIOS thing in overclocking section check screen shot first post.
I should add and i know you know but it will get better with newer agesa release coming

Thanks I check out the thread.

@gerardfraser Good find, thank you, now I can try undervolting

 

[CrackingJones]

I don't have this in my BIOS, is this an X570 thing?

 

[gerardfraser]

It is an AMD feature, now what I can not tell you all the motherboards that have it. You have to check AMD list of motherboards. It just may be AMD does not want it released yet on every motherboard but there are different links in this thread that have different motherboards listed.

Set CPU up to 5000Mhz and I see a lot of 5000Mhz but I did set locked 60FPS
AMD 5800X 5000Mhz RTX 3080 4K HDR 60 FPS Assassin's Creed Valhalla

Sorry for the dumb question but how do I get the PBO Curve optimiser settings to save in my MSI X570 Toamhawk BIOS ?

Everytime I make a change from the 'Settings' menu and F10 it says no changes have been made !?

I can make changes to the PBO settings from the 'OC' menu and this saves back fine.

Thanks

Set PBO disabled in Advanced CPU Configuration .You will get a save message.
Then set AMD curve optimizer ,you will not get a save message but that is how it works.
You are correct with your post.

Thanks. Yes, I worked it out in the end, even though it says nothing has changed when you try and save it, when you test in Windows it defiantely has, so all good

Awesome have fun

 

[Chewie]

mmm...have the latest bios installed on my Asrock B550 Extreme 4, with a 5800X, and don't remember seeing such option anywhere.

 

[gerardfraser]

Well it is an AMD feature it will be in Asrock boards soon if it is not today,unless you own like a X370 or something

This worked an absolute treat on my 5900X

[gerardfraser]

Awesome ,I have been doing 5200Mhz all cores but getting some of the famous whea errors at 5200Mhz. 5100Mhz no errors have yet to try 5150Mhz

Cinebench full run 5100mhz

 

[zx128k]

Did your 3800x degrade?

very nice 5.1ghz and just 1.2v
