help with undervolting 5800x3d

[tabascosauz]

ok so for everyone who still interested i finally got the cooler nh-d15 today and everything went as expected the scores is the same as the pic above that end that problem so thank you all for helping

Awesome. Enjoy!

Hijacking a little based on source content.

I have successfully done the in windows PBO2 undervolt with my X3D, -22 all core allows sustained clocks of 4450mhz all core in games, don't really feel the need to push further as it's rock stable, lower temps and not dropping clocks at all in game.

My question is, I feel like someone has previously mentioned it may be possible to find or request a custom version of my motherboard bios to allow PBO2 UV with the X3D, anyone here know who or where I would ask for that?

Ask reous or some of the other bios modders in the 5800X3D thread:

Ask reous or some of the other bios modders in the 5800X3D thread:

Thank you very much! it may have even been you that first suggested it to me

Bonus question, is there a way to boost clock speed at all on the X3D, in windows, bios or otherwise? or is 4450mhz where the buck stops?

4450 is where it stops for >3 cores, if less cores active then up to 4550

So far no one has cracked the Fmax wall, if you try increasing Fmax then CPU goes to base clock

Whats the temps like now?

D15 should be about as good as you can get

I am running the chrome.max version of the NH-D15 with only one fan on it.

I don't do intensive loads only gaming and so far I am not disappointed good choice and I am running -50mv on my 5800X3D while gaming.

this test with background apps running without that i could get over 15000

2 fans here and -30 didn't yet test games don't have time

asus boards have mods for it, i just googled my board name and bios mod

Should have bought the Asus, the Gigabyte is good and all but I miss my last Asus board, never gave me a hiccup. Doesn't look like anything is available for the Gigabyte X570 I Aorus Pro WiFi

try asking verangry on ocn if he has made any or be willing to make any. He did a bunch of MSI BIOSes upon request when there were none, I used his A.71 mod for my Unify-X before switching back to reous' 4006 on Impact.

There's really not anything too special about the different vendors, it's just about getting them packaged back up properly to flash with flashback. Asus seems to be the only one where BIOS flashback is fussier as to the file. Doesn't hurt to ask, that's how we all started.

FWIW, my 5800x3d runs best at offset -12, and is crashing and hot (85+C) at offset -30.

Temps are about 70C with offset -12 when running cinebench R23 with an ambient of 20C, and scores are the best with this offset.

My advice would be to take the time testing different offsets and check stability with corecycler. I personally take stability before performance any day, and in this case I have actually both.

Mine just went to -30 and stayed there, it's very likely implemented different between boards

Another Quesytion for the brains trust.

Undervolting my 5800X3D has been very successful, and I've followed the GitHub guide to apply at every start-up too. But I also now I've been dabbling with PPT, TDC and EDC, and found values I like.

It's not obvious to me how to add those 'arguments' to the scheduled task I've created, I've put my per core UV in there but don't want to break the task by getting it wrong.

Any help appreciate, and screenshot for clarity of what portion I'm talking about.

Quick bump for my previous question, hoping someone has crossed this bridge before.

@wolf From the author https://www.overclock.net/threads/c...imizer-settings.1777398/page-45#post-28999750

Use the following arguments order
1 2 3 4 5 6 7 8 ppt tdc edc fmax
All four limits are required, use 0 to not override.
e.g. to set only EDC limit to 320A

'path-to-a-binary\PBO2 tuner.exe' 1 2 3 4 5 6 7 8 0 0 320 0'

Quick bump for my previous question, hoping someone has crossed this bridge before.

I don't use PBO2 for mine (not on windows), but found this info that you need to add the PPT, TDC, and EDC to the end with no commas, followed by a 0 (for no change to max frequency?).

120 PPT, 75 TDC, and 105 EDC in the example taken from the site.

Ryzen 5800x3D Undervolt Easy Tutorial: Better temps, less power consumption, better CPU.

This amazing CPU runs too hot even with a good cooler. To my surprise doing an undervolt gave me better Cinebench 23 scores while running -12° cooler. Going to google and youtube searching for tutorials is kind of scattershot so I wanted to post the amalgamation of info found on how I made my...

@3x0 and @Super Firm Tofu many thanks for that, I'll add those arguments to my task

I'm so glad my asus board has the settings unlocked for BIOS entry

Could be irrelevant but does undervolting 5800x3d cause games to crash?

I have it at -30 for many months now, but playing new games like NFS Unbound and Warhammer Darktide crash very frequently. No issues with NFS Heat, Vermintide2, COD2022, OW2, Shatterline...etc

Any undervolting can cause that, yes.

The x3D seems to react differently to the undervolt than the regular chips by lowering clocks, but yeah it totally can be related - CPU's use different instructions, thread counts, etc. Even something as simple as using AVX or not

Hi Jacks,

just applying offset will never help you. You have to change values in this Limits window.
My 5800x3D run on:
PPT 90
TDC 60
EDC 110
with offset -40

If you do not know or can not use PBO2Tuner app, navigate yourself into app folder and use
command "PBO2Tuner.exe -40 -40 -40 -40 -40 -40 -40 -40 90 60 110"

in your case I suggest to use only PBO2Tuner.exe -10 -10 -10 -10 -10 -10 -10 -10 90 for just confirm your CPU will be limited to 90C with some offset.

I highly recommend you to use Ryzen Master to see on home page that circular graphs simultaneously with Cinebench.
1) First make your goal (lets say 90C) PBO2Tuner.exe -10 -10 -10 -10 -10 -10 -10 -10 90
2) If stable, jump to -30 PBO2Tuner.exe -30 -30 -30 -30 -30 -30 -30 -30 90
3) When you will find your offsets, start adding TDC till it will run arround 90 % utilisation - watch for it RYZEN Master circular graphs during stress test. PBO2Tuner.exe -30 -30 -30 -30 -30 -30 -30 -30 90 60
4) Now lower EDC to match your silicon, again use circular graph in Ryzen Master to be around 95% (my lowered to 110 - PBO2Tuner.exe -30 -30 -30 -30 -30 -30 -30 -30 90 110

It should be easy and can be done under 10minutes (plus stress testing afterwards)

wish it will help you and others
cheers, Zdenek

Why use software? BIOS is the best way to get it done.

Eventually I found it to be an OS problem. Reset the system and it has been fine since. Nothing to do with the CPU or GPU (which event viewer keeps mistakenly referring to having errors).

afaik expanded curve optimizer limits beyond -30 is an AM5 exclusive on a hardware design level. Not seen anything to suggest otherwise on AM4. If your HWInfo during benchmarks shows that -40 is actively making a difference to any combination of VID/Vcore/clocks/temps/power/current then it might suggest that has changed, otherwise -30 is still the limit.

If you're seeing WHEA errors that's infinity fabric related on ryzen, and 100% fixable

Software can control the idle settings for the hardware, so an OS reset or a settings change could make it more stable by not idling the same way
