***The Official 5900X \5950X owners thread***

These are excellent scores. I cant get anywhere near that with similar settings. What board are you using?

Regular hero. Also ran that with 3600c16 dcop rather than tuned. Starting to get an understanding of how to oc these. Sold that chip today and have 5950x arriving soon so will stop playing with it as respect to the new owner! :)

Still another +125 pbo to play with on that chip along with tuning curve and playing with vcore offset. I'd imagine it'll maybe take a few days to get a 5950x dialled in totally.

Well, first things first, use HWInfo to see which are your top 4 cores on each CCD.

On the first CCD I divided the cores as Strongest, Strong, and others

Strongest cores: Negative 12
Strong cores: Negative 16
Others: 24

On the 2nd CCD
Since the 2nd CCD is "weaker"

Strongest and strong cores: Negative 16
Others: 24

I set the boost to 100 and I'm trying to "maximize" this boost setting before going to 125.
My Power Limits are set to Motherboard
My Scalar is 10x

--

I have 2 bios profiles, one with Limits to the motherboard and the other to use Auto. Temps are in check on both but when I'm just gaming I use the Auto power limits.


I'm still testing.

I started by setting the first CCD ( strongest in my case ) to 4 and the second CCD cores to 12 ... then I started dropping and testing. I started by dropping the weakest CCD cores first where I found the 24. Then I went with the strong cores and finally the strongest.

--

And before you ask why 16, 12, 24 and not 15, 10, 25 ... i have this thing that I only use multiples of 4, maybe because I'm a product designer and 4 and 8 are multipliers that can be used cross-devices and get absolute values but that's a different topic lol :)

That’s some great advice there, I now have most of my cores boosting to 5 ghz and pulling lower volts, and it seems stable at the minute ;););)
 
When using PBO in combination with Curve Optimiser, is anyone else seeing a disparity between CCD0 and CCD1 boost? Playing around with various settings and frequently seeing 4.4ghz across all CCD0 cores, and 4.3ghz across all CCD1 in Cinebench R23. Stock PBO will hold much closer numbers, although still a slight difference (4.31 CCD0, 4.28 CCD2 for example). OCCT Large will hold exactly 4.5ghz across all cores, both CCDs. Edit: To be clear, I don't expect C23 to hold 4.5ghz same as OCCT, I know it's different, just noting that something will boost all clocks the same under some circumstances.
 
Running into some really odd behavior since getting my new 5950X. In Windows, on the latest chipset drivers, the AMD Power Plan is gone.
On Balanced, and High Performance, my CPU never downloads. It's voltage is 1.4 - 1.45, and hits 71-76 Degrees Idle.
Now if I run Cinebench R20, r23, or the Aida64 Stability Stress test, my temps actually DROP, and max at 60 degrees.

Oddly when I power the Power Saver plan in Windows, my voltage drops to 0.9, and my idle temps are 37 degrees.

It's only with Balanced, and High Performance that my voltage is always 1.4 and higher, with idle temps in the 70s.

Even editing, the power plans to have a minimum CPU state of 5 or 0% does nothing.
Only the Power Saver plan actually lets the CPU idle, and drop voltage.
I've got the latest BIOS from December 8th 2020, Latest AMD Chipset drivers, and a Noctua NH-D15s; and yes, I've applied paste as well.
This is also a fresh install of Windows, and did it thrice, just to be sure.

I noticed the same behaviour, mentioned it to a friend who has a 5900x like myself, same behaviour - only way I can get the system to idle is selecting power saver mode

Same here! It's mind boggling. I made a post on the AMD support forums, but not heard anything yet.

Not sure if its related, but there is this thread here i found yesterday , if you look at the post by euro sennin, i followed what he did part from the tpu setting as couldn’t find this in my bios, but i was getting 74-78c after install on Friday of my 5950x after his changes im now getting 40-45 c idle and 65-75c depending on load, but looking thru this thread it seems to suggest there is a problem which agesa 1180 might fix but who knows

Robert Hallock responded to me on Twitter, and thinks it might be a "parasitic" background app; but my CPU usage is 2-8%, on a completely clean install of Windows.

Yeah, I use it. No issues for me. Odd for me is I don't have the AMD power plan....

There is no AMD Balanced Plan for ZEN 3 users. Out of curiosity can you open the Windows Balanced Plan and select "Change Advanced Power Settings" and then scroll too "Processor Power Management" and click "Minimum Processor State". It should read 0%, if not change it to this and apply. Let me know what happens

On my system it read as 0, changed it to 5% to match the power saver mode but that didn't change anything

Sorry mate it was a shot in the dark. Any back ground apps along the line of icue running? they seem too add quite a bit of temp to my system. The other thing i did was set a -0.075V offset to the vcore, it dropped my temps and my sustained frequencies yet gave me much better performance. Also have you flashed latest bios and cleared Bios (set Defaults)?
