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
ocpak/octools
FAQ:
7950x not boosting pass 5.5G -> check that CStates is not disabled
Detailed Explanation on CState Boot Limiter
Test BIOSes:
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)
strixe-e 1515
for crosshair and strix e-e:
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, this is a most excellent chart analysis! This makes me feel a lot better about pre-ordering the new Asus X870E Apex motherboard instead of a 9950x3D. I just wish Newegg would get stock early and start shipping out. 😎

Anyone out there running a 9950X3D on a Crosshair Hero X670? I'm only able to pull -20 CO as of right now. So far -30,25,22 all cause the system to freeze at idle. I know this is more than likely just a chip issue but I'm curious if bios versions can improve this over time or if I'm just out of luck to get any higher.

In my case, one of the 16 cores had an error at -15
so I used corecycler and prime95 to set it for each core
and there were some cores that could pass at -40
03-25-2025 03:50 AM
That's the best way to do it... Except I'm horrible at this and I gave up after a little bit and just did per CCD. -20/-18. I definitely had cores that could do -30 because it would stay on for a good amount of time, but I just got tired of adjusting values and needed a break lol.

Is HTFmax activated on 9950x3d like 9950x ?

Hi, I noticed that VDDIO/MC Voltage on auto has the same value as VDD and VDDQ. If my ram is 1.45v so VDDIO/MC Voltage is 1.45v is this not a dangerous value? CPU Ryzen 9800X3D
03-24-2025 11:04 PM
i am doing daily 1.45 vddio for 6 months. no problem so far. if you buy an expo 1.45v kit and enable expo, asus automatically sets vddio 1.45
03-24-2025 11:17 PM
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

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?
