X670 / X870 resource thread

[Shamino]

ill use this thread to collect some new test bioses for the boards, maybe also to explain some less understood options

to disable cores ccd go here and choose ccd xx bit map down core.
each ones stand for an enabled core
best to disable from the back, ie:
110000
instead of 0011000
after selection press downcore apply changes or discard if made mistake

new:
X3D OC Preset for those MB with asynch BCLK Support: (for simple slight perf boost for X3D)


DOCP/EXPO Tweaked: (for simple timings tightening)

explanation of segment2 Loadline:

customize a heterogenous loadline for a dual segment workload range.

example above shows loadline=L6 when current is in range of 0~40A, and Level4 when current is above 40A.

Adds for x3d

dynamic ccd priority switch with core flex, os / driver agnostic so win10 win11 ok





Algo as follows:
If condition reached and ccd0 specified, then check current mem/cache activity > threshold and hysteresis reached, if fulfilled then switch
If condition reached and ccd1 specified, then check current mem/cache activity <=threshold and hysteresis reached,, if fulfilled then switch
Default hysteresis =4

Can combine multiple algos for ccd priority so combinations are wide

works on non x3d too but of course senseless on it. detailed explanation here.

Thank you for your reply. It's a bit higher voltage for the automatic 1.45v is about 1.47 . Does anyone know what is the max daily use? There are kits that also have 1.5v

[UTVOL06]

Same here. 1.45v VDDIO on Auto rules. I've seen multiple comments from some experienced users saying that a voltage between 1.45-1.50v is completely safe on the memory controller (VDDIO) for the AM5 9000 series. On Intel's 13900K/KS 14900K/KS a normal memory controller voltage on these CPUs for the 8000-8600 MT/s range in Gear 2T, would be anywhere between 1.45-1.55v max. Not everyone can do 8000 or higher on these Intel CPUs. The memory controller's strength/quality is typically independent of the CPU's bin (SP) silicon quality in regards to it's frequency and voltage required for the vCore. Sometimes the SP rating for the memory controller was just not accurate at all. Some would show having a lower than average or average memory controller SP score, but would end up being able to do a much higher DDR5 frequency while remaining completely stable. It's all really just a roll of the dice.

Hey, help me
On an X870E HERO (BIOS 1301) with 9950x3d, even though Ive specified 1000 for the PPT/EDC/TDC Limit, the CPU only goes up to 240W (CLK 5.1K all) on CB23
and the CPU temperature is around 70 degrees
other settings are PeakCurrentControl=disabled, Scalar=10x, CO=-20(avg), and CPU LLC=Level8
Are there any settings that are missing?

[X_Disturbed_X]

Maybe you've hit the HTFmax  limit ?

that's what i am asking for.  9950x has an embedded htfmax limit @ 5.375 ghz and ~1.3v all core.

is it same for 9950x3d ?

[pararin]

HTFmax limit has not been reached
previously, the X870E ProArt 9950X was able to increase to 290W
It is possible that you have overlooked a hidden setting or there is a problem with the BIOS imo

[UTVOL06]

So unfortunately, I found out that my 6200 FCLK 2200 is not completely stable. It's hit or miss. I think with some voltage adjustments with VDDG IOD & CCD, I might be able to get 6200 FCLK 2200 stable. I am not sure it's worth the added effort to be honest.

• Here is a comparison between DDR5 6200 FCLK 2200 vs 2167. BIOS Options: CL26-36-36-64, UCLK = MCLK 1:1, GDM disabled, Nitro Mode: 1-2-0. I am utilizing the "Rift Breakers" free PC demo utilizing the built-in CPU Benchmark. *I just noticed that the only difference besides the obvious different FCLKs between runs would be using Full Screen vs Borderless Window between the two runs. Everything else is identical. Hopefully this didn't make a difference.  I'll have to retest after work.

1.  1️⃣.  FCLK 2200
2.  2️⃣. FCLK 2167

EDIT: Another user reported this is likely a Memory Training issue than an FCLK issue. Apparently in some of the BIOS versions released the memory training is not completely consistent with one another. One boot up you may get some reduced 0.1% lows and the next you don't.

Old issue coming back. Thats is the result above, however after reboot/shudown, tm5/karhu fail at once.

[UTVOL06]

Have you tried the X870E Hero Beta 1301 BIOS yet? I just updated from the older 1003 to 1301 beta and everything is running well and stable thus far. I believe a new beta is supposed to drop soon if you would rather wait. I also use Karhu to test for errors. I've been also using the free "Rift Breakers" PC Demo's built-in CPU benchmark test to also help Identify FCLK instability. Typically the unstable FCLK will have lower 1% and 0.1% lows than the next down stable FCLK at the same DDR5 speed. 

[TMavica]

Thats not FCLK instability, Karhu speed without dropping, linpack xtreem no drop of gflop. Mostly is the BIOS or memory trainning problem, the issue happened in previous bios too (forgot which version), but later bios fixed that, now the issue came out again. Also no any issue reboot to reboot in 1:1 mode, it works without any error each time from rebooting. Only 1:2 got the issue
