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

[gerardfraser]

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

Thanks.

I can not I only have 5800X and no Fire Strike Extreme.not to exciting

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?

Under water 4900mhz could be possible maybe start checking hot bot or something.
24/7 more likely 4850Mhz may be the limit on 5000 chips all core all the time

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

I am pretty sure that's a RAM or FCLK issue. I got the same results trying to OC RAM to 3600 on the same board. What appears to be stable in stresstests causes browser tabs to crash (specifically the ones playing video), and loosening timings didn't help at all. I gave up and switched back to XMP, so far no issues running -15 all core (+100 MHz though, +200 wasn't stable for me as well).

Hmm interesting. Well so-far no crashes after lowering to -5 all core and +150MHz boost. I ran video in browser for a few hours and no issues. If that changes though I may look at adjusting ram, but I'd rather keep it fast and tight if I can

+200Mhz override with negative -5 curve

Hi guys, just wanted to chime in here.

I have a 5950X on a Asus Crosshair VIII HERO motherboard and I too would like a piece of the cake.
I'm pretty new to overclocking CPU's, but luckily, AMD has had me covered mostly on that part.

I do notice some hiccups in games here and there, and it made me assume that it is due to cores switching from sleeping. This is just a thought.
Anyway, I first was going to test a manual overclock on all cores to see if it went away, but now I found your thread, I want to try this curve optimizer.

To be clear, starting from a factory resetted motherboard, I am just going to the Curve Optimizer option and setting all cores negative -15 and that's it?
Or do I need to tinker with other options aswell to get the best results like you.


Thanks in advance!

cores switching from sleeping

unlikely
i barely see cores sleeping on Balanced power plan.
blame storage or memory or drivers

Well, yeah, this is kinda last resort for me as I've already done a full reinstall of Windows and installed latest drivers without all the Asus bloatware.
It's just noticable on my GSync monitor as normally it's buttery smooth, so everyime the frame hangs for even a microsecond, I notice it...


My plan was to change BIOS Ram timings to stock DOCP and apply the curve optimizer as said here.

 

[depatere]

So I just updated the BIOS and set the AMD Curve Optimizer to all cores negative 15.
When I'm running Cinebench R20 - I see cores boosting to 5050Mhz, but most are lower around 4775Mhz - 4800Mhz and some even lowest at 4500Mhz.

Is this all I need to fiddle with? Or is there more to set it like you @gerardfraser

I do get crashes when running single core benchmarks..

Sounds like you have a very good chip! You have boost max set to +200mhz? Are you running default everything else? What's your FCLK and mem set to? Note that I could run mine -5 all core with max boost +200 in benchmarks, but letting the pc sit with browser video would crash after a few hours. I've bumped down to +150 and -5 all core and it's fine. -15 all core crashed on R20 almost immediately for me. I'm running 1900mhz FCLK with pretty heavily overclocked mem

I'll go into the BIOS and take some screenshots, but I'm afraid Ill need to change something, since Im crashing on single core R20 right?

Here are some more screenshots. The last screenshot is a screen of when it crashed in R20 with Boost to 200Mhz. Mem clocks have been resetted to default DOCP profile, since I updated the BIOS.


Any help to avoid these crashes would be greatly appreciated. Total noobie here

If you're crashing, yes. You can either try lower max boost or your curve numbers, or both. I'd start with going down to -10 or -5 and keeping boost at +200 and seeing what happens.

edit: looking at your numbers, though, I think it's probably the curve lowering your voltage trying to achieve that speed. So you either want to keep the curve and aim for lower boost, or lower curve to not starve the cores for voltage, or aim for a middle ground

Well, with boost set to +0, and all cores to -15 it was still crashing tho :/

Yeah, so bump curve to -5 and keep boost and 200, then if that crashes bump boost down to 150.

Thanks! Trying it out now, will update this message once the benchmark has completed!

UPDATE @schoenzy: I tried the settings you gave me, and these were the results.

Im unsure if all cores are behaving as they should, maybe you know this better? Currently the single core performance is the same as with previous BIOS without the Curve Optimizer.

Core 12 never got boosted it seems. @gerardfraser mentioned that the difference between Curve Optimizer and PBO was that Curve Optimizer would utilize all cores and boost them to 5Ghz, but this is not really happening on my system, as a lot of cores are still not going high..

Also, whats the next step? Looking at the weak cores and the strong cores and see which one can be brought to -10 and -15 ?

-5 will result in milder gains in a workload like cinebench. You are still getting some of your cores to max. If you let hwinfo sit open at desktop for a while, you should eventually see all cores hit the max. From time to time, open browser or applications. See what happens. This should tell you what cores are stronger and which are weaker if eventually a few dont hit max boost. From there, you can try tweaking further on your stronger cores. What are your all core numbers with -5?

Note in either case, your system is beast and boosting high AF. I know it's tempting to want to get the absolute best numbers possible, but at some point you gotta be realistic and be happy with a nice middle ground of optimized performance and stability

If you eventually want the highest single core number possible, go for more aggressive curve on your top few cores, and set cinebench affinity to your top core only. You can't expect each core to get the same score on its own.

I totally understand, I was just trying to figure out if anything was wrong with my system
Just wondering what would have more impact on better single core performance for gaming overall. -10 or +200Mhz boost.
That I do not understand quite fully.

What are your all core numbers with -5?

How do I check this?


Already a big thumbs up and thanks for following this up with me

 

[steverebo]

Whats the maximum safe 24/7 voltage on these chips?

I've got a semi stable oc of 4.8ghz all core @ 1.35v my r20 score single core is 621 only 5 points off my previous score when I was boosting to 5.1ghz

Nothing looks wrong with your system. Just run cinebench all core and look at hwinfo, what does the frequency hold at.

Also, if you want realllly max numbers, set cinebench priority to high in task manager details, close everything you dont need like icue or other rgb software. hwinfo likely wont update in realtime though. Doing just that I go from 5750 to over 6000 in my MC cinebench scores

Gaming overall you're honestly not going to notice a difference between like +150 or +200, maybe a couple fps. Any decent max boost bump with PBO on will pretty much max out your fps gains. There are other gains to be had with memory settings. Again, what's your FCLK set at? Mem speeds and timings?

@depatere
I am no expert or know anymore than anyone else,I just do what works on my PC.
First off this is overclocking, if you want instant overclocking AMD supplies this perfectly well out of the box and nothing else needs to be done. IF you want to tweak and this is where it may take testing over a period of time longer than a couple hours on a forum.

I agree with @schoenzy
Find the lowest clocked core with PBO boost on without AMD curve optimizer on. Use AMD high performance power plan or windows 10 high ,makes no difference. IF you use power or balance then the CPU clocks can clock higher but not hit all cores. You want to see all cores highest boost per core. I perfer testing highest clock per core with light CPU and HWinfoinfo64 open but if you in a hurry download the tool I linked.

Boost Tester
Here is a shortcut on testing highest clock on each core. This will test each core for 5 seconds
https://drive.google.com/file/d/1ETV-ZXgI6qB2LXzLNr13e90PXQ87jplg/view?usp=sharing

Next here is an AMD curve optimizer chart I done for each core voltage offset positive/negative. On your weaker cores add a positive voltage/ or high negative number to give that core more voltage to advoid crashes.If you still get crashes after these steps on load then doubt it is not your CPU.
https://docs.google.com/spreadsheet...QvVSKyfD4DQghgUHb46-VIIzl3BQvX-hYt0D4/pubhtml

Good luck and let us know what happens. The 5950 should be able to boost higher than my 5800X 5100Mhz on all cores.

I'll be happy to report what happens. Although, the spreadsheet you gave contains data that I can't seem to find anywhere in this thread on how to implement.
I'm really unsure how I should use the spreadsheet ?
