Precision Boost Overdrive Override

[gerardfraser]

So I was wondering how much over max boost can you get on a Ryzen 3xxx CPU.

Motherboard MSI X470 Gaming Plus + 3600X
Max over boost on 6 of 12 cores is 125Mhz for total of 4525Mhz.

Updates to Precision Boost Overdrive Override for the AMD Ryzen 3000 Series can give an addition 200Mhz added to what is printed on the box.

Anyone have any luck going over max boost clock.

CPU-What is printer on the box.
Ryzen 9 3950X -4700 Max Boost
Ryzen 9 3900X -4600 Max Boost
Ryzen 7 3800X -4500 Max Boost
Ryzen 7 3700X -4400 Max Boost
Ryzen 5 3600X -4400 Max Boost
Ryzen 5 3600 -4200 Max Boost

MY 3600X Hitting 4500Mhz Cinebench 20

Video showing max over boost in a couple games and Valley Benchmark 1.0 running 4K where you need every Mhz J/K.

EG:

My 3900x has at most hit 4550mhz that I have seen with hwinfo. It averages about 4200mhz when gaming with a game that only uses 2.5 cores. It seems to rarely boost higher that 4250mhz.

What is the very first game in the video? looks scary as hell.

3900X is capable of hitting 4800Mhz.
Time to try different BIOS and setup PBO Override and see what happens.

Great game and looks and plays awesome in 4K and has some scary stuff.

I am still waiting for an update to my motherboard bios.

 

[TheLostSwede]

Ha, my 3800X won't even go past 4400...
Not a single MHz. That's with a 280 aio liquid cooler.
Either broken UEFI, or AMD really messed up this time.

 

[Nordic]

The IPC gains are certainly noticeable. It is faster than my old 4790k, but I basically have a 4200mhz cpu that sometimes clocks higher if conditions are right. I am happy that I have a performance improvement, but intel is much more consistent with the higher clocks.

I enabled pbo overdrive. I haven't caught it going over 4550mhz, and that is at idle. If I put any kind of load on the cpu, be it single core or multicore loads, it will only run at 4200-4250mhz. What use is AMDs boost if it only works effectively at idle?

3700X...Cooled with a Kraken X62 and has never once boosted a core over 4.3Ghz.

I am sure AMD will get worked out by the end of September,I can only show people how it is supposed to work and what I did to get it working.
I only game so the way it works as is for my combination of gear suits me fine.
For someone who bought any combination CPU/Motherboard and the gear does not work as intended even though it is a fast CPU would make me submit tickets to AMD/Motherboard Manufactures everyday or I would return my gear.

 

[Nordic]

Don't get me wrong, I am happy with my purchase of a 3900x. I am annoyed with amd's boost feature because it doesn't really work as it should. I have no faith that amd will release any combination of drivers or bios revisions that will improve boost. These are 4.2ghz chips being sold as 4.6ghz chips.

Edit: @TheLostSwede what temps are you getting under load with that cooler? I hit about 68c with my mugen. I am thinking about going back to custom watercooling which could keep the cpu at 40c. I wonder if temps that low might actually make a difference.

 

[purecain]

i'm in the same position with my 3900x. I sit at 4.2 most of the time. odd boosts to 4.4. if its gone higher than that I havnt noticed. I havnt even looked at the setting properly but hopefully I should be able to set a higher boost clock.

Really? I thought I had a bad one but even I got 4350 with the Wraith Prism

 

[oxrufiioxo]

Why is your Vcore so high 1.5-1.6 during load.

Are you trying to kill your cpu?

Single core PBO+. Hes allowing the CPU to zip half the juice of what his CPU is rated for (stock) into 1core

 

[purecain]

His cpu is doing that by itself, its for the boost. I lowered it on my old 2700x but the new thinking on the matter is that amd intended this much voltage to be used in these such cases.

My 3900X sits in the 1.35 range during load with pbo enabled so him hitting near 1.6 seemed odd to me

It will vary by motherboard PBO+ settings. Hes running MSI enhance 4 might be different on ASUS, ASRock, Gigabyte.

 

[purecain]

I noticed it on the asus crosshair VI hero. I lowered it at the time.

 

[gerardfraser]

Well no worries on my part about CPU reading voltage in Boost mode.It is fine and can read up to 1.57v CPU ,the CPU is just doing it own thing as purecain and Xzibit pointed out.

How about I spread the love around for my CPU with some low voltage .Actually I can run 4250Mhz and there is no difference in gaming on the Ryzen CPU,but I like the boost even if it does not matter for performance.
3600X All Core Overclock 4425 Mhz CPU 1.325V for oxrufiioxo so do not feel to bad for me.It is all good ,really it is.Plus i bought 2 x 3600X in case one blows up ,also they have warranty with years left on it.

Yeah, after some back and forth with AMD's support, they said they're aware of this issue happening for some people and they're working on it...
Let's see what happens.
Gigabyte released a new UEFI for my board this week, but it made zero difference.

Around 70 during heavy load, less in games.

That is disappointing. I have never been a fan of the aio cooling when air cooling performs just as well. I have yet to find results from someone with true custom water cooling. I might have to set it up myself just to see if less than 50c temps do offer better performance as rumored.

Disappointing? Keep in mind that I live somewhere hot and humid, so can't really compare to what it would be like in a cooler climate.
Also, my cooler is set to quiet, which I guess means not the very best cooling performance.
I can have a play later and see what it does at a higher "noise" setting.

This is after 2:30 minutes at 100% load.

 

[londiste]

The maximum I saw for my 3600X was 4300MHz for a split second. With any actual load 4249MHz and usually 4219MHz.
Software-reported voltages and power consumption figures are roughly in the same range as on screenshots.

Load temperatures are going to be awful with 1-2 core loads. Zen2 gives 1.5V to single core and 1.45V to two cores on default settings, pushing large part of the TDP into 1 or 2 cores. All-core load temperatures are considerably better, both because voltage and resulting power consumption are lower as well as heated area is bigger.
