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

[kaiserc]

All Motherboards except MSI are limited to 200Mhz,want to go higher use the new ASUS tool released ASUS DOS Overclocking


I used a 5800X,5600X boost is what out of the box 4750Mhz.

You can set whatever you want and check stability for higher scores even if that is what you want. 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.

4600 is offically the boost / but everyone's getting 4650 (50 probably from PB) . So i'm going to need offset +350. Its On MSI B550M Pro-VDH with an air cooler. But this is a PC im selling. I hope Asus have all this sorted on my pc's ASUS B550m Tuf Plus, If not I will have to get a b550 mortar. I have Arctic Liquid Freezer II 240 to cool.

Well you got good gear. The boost out of box should be 150Mhz more than what is written on the box,but if you say it is 4650Mhz ,that is still great.

How are people stress testing this??

My 5900x is set to 1.3v vcore and then pbo curve negative 5 across the board and +200mhz and its boosting up to 5150mhz

Also what are people setting all the limits at are they being left at default or being set manually

Setting the vcore to 1.3v is the same as default setting after vdrop on Ryzen but with the curve optimizer you can have higher sustained boost clocks like in first post on here.
I leave all setting for myself on manual but it is a PC you can adjust any setting if you think you may get an advantage for lower heat at peak heavy loads or whatever.
Stress test for me PC games only and have been since I can remember for myself.

First run of r20 single core only scored 576 but had what looked to be sustained boosts to 5124/5150

Over 8000 multi core

 

[snebbeg]

dang, nice boosts what you cooling that with ?

 

[steverebo]

Custom loop, boosts seem nice but single core score seems lacking

Score should be almost 100 points higher with those clocks.

I know, can't seem to work out qhats causing it as I hit a multi core of 8756

 

[gerardfraser]

I can explain the score and AMD said they were going to fix these things in new BIOS ,should be soon.
@steverebo return/exchange your CPU to get a better one.Might be tough explaining you got one of the bad ones with terrible temperatures,although that would be bad excuse for return.Custom loop look at #62 in this thread by me and the link AMD temperature expectations .

Here is what is going on and the low scores,while trying to fix your high temperature problem ,you have initiated clock stretching on your AMD CPU by using a low voltage on AMD CPU which sucks.

Example. Set Voltage 1.32 vs default voltage. AMD CPU are somewhat smart when things change.Default voltage for best performance. If you want higher scores for anyone,turn everything off that does not need to be running on computer.
560 vs 656

 

[Joxeon]

It might be some kind of clock stretching, try upping vcore to 1.35 and see if scores improve if it does then that would confirm.

 

[steverebo]

You guys smashed it!! Just set my vcore to auto along with no overclocking and just pbo and hit 612 single threaded.

Almost my temps have sorted themselves out currently sitting 28 degrees idle must have had a huge bubble in my block that wouldn't clear with shaking

 

[gerardfraser]

That is awesome news,you got one of the best CPU's going.Enjoy

 

[steverebo]

Its funny because I don't have a clue what I'm doing just set the pbo curve to negative 5 on all cores 200mhz boost on both pbo and pbo oc and pressed go.

Really want to learn how to truly tune this cpu for longer boost durations and higher multi core boost

 

[gerardfraser]

Well you have the tools and like I said in another post,you will get it.Here is the funny part AMD has set algorithms for best all around performance already.
Clocking the CPU higher has no actual real benefit on performance in all most all applications and none in PC gaming at higher resolutions past boost clock.
So what I mean is AMD CPU running on a boost clock lets say 4650Mhz will get the same FPS as a AMD 5100Mhz.

Now there are some people out there that saving a few seconds over an hour of average work might be all that is needed.
Some playing PC games with RTX 3090/AMD 5950 at 1080p looking for 5Ghz ,now that is a special kind of person. The only reason I say this crap is because I tested the stuff myself but I do like seeing 5000Mhz + while PC gaming even though I actually know itt does not make a difference in performace at all.

Thats interesting as I'm so used to overclocks making a huge difference in games on my old 10900k.

I feel the same though, I do like seeing over 5ghz

Curve optimizer at -5 all cores has allowed me to get all cores above 5GHz and 4/8 up to 5050MHz. My system was not stable at -15 all core, or -15 top 2 cores with the rest -5. I may play around more but for now this is fine.

Other specs/settings:
- MSI X570 tomahawk
- BIOS 7C84v14 1.1.0.0 Patch C
- FCLK 1900MHz
- PBO Auto w/ Curve Optimized Negative 5 all core
- 2x8GB Corsair Vengeance LPX @ 3800MHz 16-19-16-36-60 1T and full sub-timing tune 1.38v
- Windows Balanced power plan

Cinebench
ST: 624
MT: 6008 (score increased by 250 by setting Priority to High)

My chip runs pretty hot regardless of PBO and whatever else. I'm using a Corsair H115i with 3x 120mm intake, AIO 2x140 push top exhaust and 1x120mm rear exhaust. Custom fan curves helped, gaming temps are fine, but Cinebench gets real hot. Re-pasted and didn't make a difference.

QUOTE]

as an update, my system randomly crashed watching browser based video, despite making it through cinebench and no crashes left on idle for hours. I've bumped boost down to 5Ghz, and left curve optimizer at negative 5 across...we'll see

 

[gerardfraser]

Yes for sure that can happen on Idle with overclocking. Just this past week I had 3600XT/5800X that worked great in the MSI X570 Tomahawk. With my 3800XT had to return it because of crashes on Idle,I could not solve the problem. Other people have crash on Idle it may be problem with various BIOS. Also I get errors with my testing my settings too high 5150/5200 boost getting errors and crash on Idle at least once overnight. I am happy with my results I may do the same as you and go to Negative 5 and leave it ,as I just like seeing 5000Mhz it does not matter what 5000Mhz is.

 

[steverebo]

Whats the highest all core oc people have had with the 5900x i have not tried it yet but it seems like all my cores are boosting to about 4800 so would a 4900 all core be possible?

 

[GioUK]

Can you post some 3dmark results? I would love to see the physics score on Fire Strike Extreme.

Thanks.
