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

Yeah I'm worried I'm going to have to drop down a bit. Completely stable in cinebench, cpu-z and gaming with +200mhz, but had a random crash last night simply watching crypto stock feeds.

It did seem very random for me too.

I was using +200Mhz and passed a Cinebench, 3dmark and cpuz fine, then left it thinking it was ok. The next day I powered up, changed no settings and instant reboot just oprening the Battle.net launcher. I put it down to instabilities in the beta BIOS, but then the non BETA also crapped out on auto PBO just running Cinebench.

For now it seems stable with Auto PBO for me so will leave it alone

Edit. Interesting watch

Skip to 21:30. PBO seems broken (for now) and performance doesnt match clock speed. PBO appears to increase voltage but that's about it

It's all about the Curve Optimizer guys.

Here is a video of the official AMD tech briefing on Precision Boost 2 and the Curve Optimizer and explains everything: https://www.youtube.com/watch?v=2Jo2ck6xzDM

Here is a slide from the video on where to start:

I've been messing with the Curve Optimizer more and was able to decrease temps, increase stability, and increase benchmark scores:

Every processor is different, it'll take some time and tweaking to know which settings in Curve Optimizer is best for you...

What motherboard and BIOS do you have?
What PBO settings do you use, what cooler and what max temps?

Thanks

I had discord alerts set up, it popped up on the biggest online retailer, only £404 delivered, was on back order but came quicker than their estimate.

I had an email alert for a 5950X too a couple of days ago.
Id buy it just to sell to someone on here for rrp instead of a scalper getting it

Sure hope so because this is the worst I have ever lost the silicon lottery in all my life. The chip can just barely run at stock speeds and runs ludicrously hot, albeit in c23 testing. gaming it runs 50-60c

That sucks.

IMO there should be some quality control so all chips are equal or at least almost equal. I wouldnt buy other products like clothing or food for the same price as other people knowing they mine could be way worse / lower standard so why with PC hardware?

@glnn_23 got his 5950X to 4.7Ghz all cores under less than 1.2V

Edit
With my 5800X I installed Ryzen master, it ranked cores 1 (core 0) and core 7 (core 6) the highest.
I went into BIOS and set PBO t oadvanced, 150Mhz boost, motherboard PBO limits and -15 on cores 0 and 6.
Tested Cinebench R20, instant crash. Pretty sure its a BIOS thing on the MEG Unify. I put money on it doing better on the Tomahawk. Will wait for a new none beta BIOS

I can do 4.5ghz all core 1.25v no problem, can boot into windows & run single core Cinebench with 1.2v

Temps are ok, all core cinebench runs hit mid to high 70c, single core run is around 50c.

4.6ghz eludes me however, even with 1.3v.

Been messing with settings for days, finally given up for now. Spending more time fiddling with settings & testing than actually gaming.
 
Man i turn PBO limits to motherboard and my 5950x turns into a burning inferno... LMFAO

i have 2 massive 360 radiators on this cpu and its still maxing out temps @85c on PBO limit :motherboard but when its on auto the temps are more reasonable @70-75c lol
these cpus are quite the power hog thermal beasts when PBO limits are removed.

and how the hell do you reduce multi core`s vcore with out affecting the vcore of single core so that you dont loose the boost 5.0-5.1 that im currently getting cause if i keep vcore at default it gets as high as 1.48v but i need that vcore for stable high single boost speeds if i reduce that and get a stable a lower vcore for multi thread 4.6 or 4.7ghz i loose high end boost clocks...

i must be doing something wrong lol
 
You can set CPU override voltage to keep boost clocks ,but the trick is to have enough voltage so you do not get clock stretching. That CPU override voltage would be around 1.325 on my 5800X after voltage drop however I set my CPU.I do not know what the override voltage would be on 5950X to prevent clock stretching.
If you just want temperatures in the 50°C-60°C and do not care much about clock stretching then set CPU Override voltage to 1.25v and check out your boost.

Added CPU override mode screen

Hi there if i select that override mode then change voltage and reboot system and go into windows im locked in a static clock of 3.4ghz and no matter what i do i cant seem to get the clocks to go up or down there just static :/
 
If you have CPU offset voltage in override mode set then you will get base clocks. It has to be CPU core voltage override mode that is all I can say to keep your boost clocks. I can make a video if you want.

I made a video ,started in BIOS and set CPU Override voltage only to 1.25v and continuous shot to desktop then HWinfo64 and PC game showing CPU voltage 1.25v and boost still working normal.

Well something is wrong :( i know if i set unnder CPU code voltage : (override mode) i set 1.22v reboot system and load into windows im stuck at base clocks no matter what i do i cant change it its like my boost single core and boost multicore clocks are all stuck on base 3.4ghz clocks :(
im running a X570 MSI godlike board with 5950x and latest bios version :/
no idea whats causing this issue if i run cpu core voltage at : auto my clocks and boosts all all back working lol

i tested manual vcore @2.22v and 4.6ghz all core and seems very stable with a R23 score of around 29-30k seems the performance is there

just wish i could run override voltage and keep my boosts whats going on arghhh lol
 
Well I can only show a video on how it is supposed to work. We both have MSI Motherboards and I can say I owned MSI X470/X570 and they worked they same.

Any CPU offset voltage does not allow Ryzen 5000 CPU turbo/boost clocks and will fall to base clock. Override voltage is fine. I can say there is 3 AMD overclocking sections on MSI Motherboard,I suggest check them all.

yeah im completely puzzled, just to be sure say i wanted 1.22v override and 4.6ghz all core with 5.0-5.5ghz single core what settings do i change in the bios to get that as it might be a setting im overlooking thats causing the board to use base clocks locked when using override :/
 
Go to BIOS.
Press F6
Set all to optimize defaults and restart back in BIOS.
Do not tough anything but override voltage and put in your desired voltage. If you use CPU 1.22 override voltage you will get clock stretching but it is ok.
Only areas in red 1/2/3/4

Ok pal i reset to default then only changed cpu voltage : override 1.225v and reboot got into windows and im still stuck at base clock :( :( no idea infact i have run out of idea`s i think its a bug on the msi godlike x570 board :/
