AMD Ryzen 5000 Builders Thread

[moinmoin]

Even with a pretty beastly air cooler, my 5900X got up to a maximum of 91C at one point according to coretemp. It seems the newer, high end desktop CPUs run hotter these days in general due to more aggressive boosting compared to the older CPUs.

Such always sounds more negative than it actually is imo. The 3000 series essentially had no headroom so the boost always got stuck at some limit pretty much right away. The 5000 series has much more headroom so the boosting algorithm now is able to flex its muscles even within the stock limits. That naturally means higher temps, it's still OC after all. If one doesn't want that one can lower the respective limits.

Was building and installing a everyday computer for one of my family members earlier today and lol how easy it is to tweak a single CCD cpu running single rank memory compared to my normal rig 😆
Think i spent like 15mins to get pure T1 4000 running (no GDM).. Pretty much everything is on auto except me inputting the memory timings manually and setting 1.5vdimm


Had to change a few settings and drop to T2 for 4266 MT/s speeds but still amazed how easy this platform with single rank is to tweak.. Its like night and day between my mainrig with dual ccd and dual rank memory

Have spent close to zero time on this, and limited myself to under 1.2 vsoc because this is 24/7 daily settings for family, but still happy with the results..
This Asus b550 strix f motherboard is missing pretty much all other voltage settings anyway..

This is actually way overkill anyway as this computer will manly be used to read and surf the internet and print some mails now and then

This is my current dual CCD + dual rank memory mainsystem for comparison which i have spent months and countless hours tweaking: (also passes 25 cycles)

Actually 5700G has nothing to do with AMD desktop CPUs at all be it single or double CCD design. Being single chip monolithic design obviously helps with memory overclocking. Modern die, with more modern IMC on die, compared to ZEN2 era 14nm IOD we are getting on desktop.

True.

And even the 3d refresh isn't going to fix that on the desktop I don't think. Super curious to what they will be doing for zen 4 on this.

How much experience do you have tweaking and overclocking singel-rank vs dual-rank on the AM4 socket ?

Minor, i am mostly Intel guy. The tuning i did on 3950x and 5950x was on quad 16GB dual ranks for 64GB setup. Both achieved 3600CL15 on moderate volts.

I was going to build another rig with the 5800x. However im having buyers remorse right now. I got the Razer 8Khz mouse. On my Amd 5900x/Asus Dark Hero x570 it stutters like crazy. On my Intel 11600k rig it works fine no problems at all. With the usb drop out issues before and now problems with the mouse Im starting to regret my Amd rig sad to say.

Check for a BIOS update from ASUS. This problem is pretty much fixed, IIRC.

Man. I have quad single rank 8GB sticks and can't hit CL15 reliably. I started out with two sticks for 16GB, and they were awesome. I wanted more for running Virtual Machines and the sticks I had bought went on sale; sadly, the second pair were lame.

What firmware are you using on your Dark Hero? Asus fixed usb issues with bios version 3401. If you are using a newer version, did you try a different usb port?

i'm on 4x8 SR right now at cas 14 but Samsung B die.

Yeah, same, except Cas 16. Seems like those extra two sticks just knocked me off Cas 14 - played around with various setting and voltages on dram, dram phy, etc. Oh well, can't win them all.

Do you have GDM on?

When I moved from 16 to 32GB I was getting Errors in Test mem 5 without it on.



And now after spending a few days testing

its running with GDM off an no errors in TM5



So you may be able to run with lower timings but its going to require testing the settings and making modifications if you have the time or care enough to do so.

Im on 3801(latest) Bios. Ill check the other usb ports in a little bit.

@Muadib The mouse works now no stutter. I had to change these settings in the bios.(Thank to someone else)
AMD CBS, NBIO common options, SMU common options.

APBDIS - 1 = fixed IF P-state; 0 = dynamic IF P-state, use 1
Fixed SOC P-state - P0 highest power, P3 min power, use P0
DF State - Disable = do not allow IF to go into low power state.

There are so many setting in the bios that I have no idea what to change for optimal performance.

 

[Shmee]

Good that you got the USB issue resolved! The Asus Dark Hero is definitely a tweaker's paradise. There are a lot of options on these high end boards.

Glad you found the answer to the mouse issue. Did you get the answer from someone on Anandtech?

I knew I saw that somewhere that is the place.

My new daily CL13 and tRFC 228 24/7 memory settings
Lots of things going on in this screen, so i will also write what it show:

• 25 cycles testmem 1usmus cfg
• 3000% Karhu ramtest
• 30min OCCT Large AVX
• Aida64 memory benchmark
• CPU-Z cpu bench, ST 709 and MT above 14k

And a quick and easy gaming test in SotTR cpu benchmark with my new everyday settings. (done in windows10)
Seems like i have to wait for Alder lake for someone else to cross the 300 fps line and i can start pushing again..
My old record with everything maxed and not stable was 314 average cpu fps i think, with these new memory stick and settings it should be good for ~320-330 fps when running bench settings
Looking forward what the 5950 xt 3dnow! edition can do in this bench when i get it

This L3 Cache latency problem can affect all Windows 11 supported Ryzen processors.

In short, from Windows 11 circus the further the better.

If not broken do not repair, ride on Windows 10.

"A software update is in development to address this issue with expected availability in October of 2021." So the fix should come pretty soon. Within the next 3 weeks.

So what a shocker

MS has a "new" OS launching at the same time as Alder Lake with scheduler enhancements and everything in order make sure it works well. Meanwhile when AMD releases FX or Zen CPUs, MS is like, "yeah we'll get around to updating the scheduler a little bit in a few months... idk... we're pretty busy making sure Candy Crush works well on UWP."

AMD: Windows 11 Slows Our CPUs Up To 15%, Patch Coming

AMD has announced that all of its WIndows 11-compatible processors can suffer from reduced performance in some applications when used with the new operating system, with extreme outliers in eSports gaming titles dropping by up to 10–15%. For applications, AMD says that the performance impact weighs in at 3–5%. A software update and a Windows Update are in the works to address the issues, with both expected to arrive in October 2021 (this month).

The errors impact every Ryzen CPU supported in Windows 11. That means all Zen+, Zen 2 and Zen 3 CPUs that comprise the Ryzen 2000, Ryzen 3000, Ryzen 4000, and Ryzen 5000 processors are impacted. In addition, select AMD EPYC processors for data centers, along with some newer Athlon chips, are also impacted. You can see the full list here, but suffice it to say that every AMD chip on our Best CPUs for gaming list is impacted.
