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

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.

Yup, that's where I landed. +150mhz and -5 and it's stable. +200 and -5 was stable at idle, benchmarking and games, but would crash with browser video playing for extended periods.

yeah for aome reason youtube is a great way to test system stability - I've had gpu and cpu overclocks that seem stable in a game but then play a video on YouTube and get a BSOD

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.

@Guest2 I'm thinking of getting a Unify - would you recommend it?

I would. All working great now i've updated to the latest bios.
Probably overkill for me as is an 'extreme overclocking' board.

Still to learn more about Ryzen overclocking, but to me overclocking the 5800X at the momen is more "is this possible" thing rather than everyday use as nothing I do uses all 8 cores. Will probably just leave it on XMP and defaults for now.
DRAM I have set CAS14 on 3600Mhz RAM (2 x 16GB Team group 8 pack ripped) for 56.0ns latency

I'm pretty sure with the correct voltages and settings set I could reach a gerard level single core R20 score. I might try it at some point but there are a LOT of settings in the Unify BIOS

For now, back to Warzone

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.

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.

I agree, these look to be a BIOS issues and should be fixed with an update. Yeah this is actually my first AMD CPU I've ever owned. So far loving it

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

Same here, bit of a learning curve have not used AMD for over 20 years.

Acolyte · 20 Nov 2020 at 20:03

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?

You cant really compare the overclocking settings on these to the AMD's of 20 years ago. Back then all you needed was a pencil !

Mine boosted to 5100Mhz somehow but only single core. Multi core score wasnt good. I tried similar to Gerard but to be honest had no idea what i was doing so reverted settings

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.

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.

Same in msi meg unify bios.
Two sets if pbo options. One has curve optimimizer, the other doesnt.
One you can manually set frequency boost the other only to 200mhz max.

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

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.

Guest2 · 21 Nov 2020 at 16:18

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

I get 1.352v confirmed by CPU-Z and HWiNfo64.

edit

just added 200mhz in PBO and ran Cinebench R20 and my clocks were still 4.5ghz or there abouts but my voltage drops to 1.325/1.33v max but temp maxes at 82c !

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

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
