X670 resource

[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

7950x not boosting pass 5.5G -> check that CStates is not disabled

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)

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.

Disable memory context restore and power down mode also, see ok or not

[roupa_de_trapo]

By doing this (Disable memory context), the memory will always train again, and this does not solve the issue of loss of settings that is happening. And memory power down mode may be necessary to maintain stability in some situations.

@SAFEDISK I'm also having the problems reported by the people here above, in memory, before I could even lower the vSoC voltage, but now I have to leave it on automatic or at 1.3v. The released version presented a slowness problem on the BIOS screen, it seems that there is an overload making the system slow, in the later beta version, there is still some slowness, but a little less inside the BIOS. In BIOS 3014, depending on what I did, I couldn't even adjust anything anymore and the system would freeze. If you need more tests or a specific report, comment so we can try to test it or if you have a new beta so we can evaluate it.

[TMavica]

For me, i never trust memory context restore, it causes stability, I always keep PDM, GDM and MCR disable. Asus memory trainning is questionable. I do 6500C26. 

[roupa_de_trapo]

training gives a small gain, but obviously it won't be perfect and therefore new features need to be tested.

[74lobster]

Already done, but I f I set: Memory Frequency: DDR5-6400, Windows 11 Pro crashes immediately after completing the boot.

[roupa_de_trapo]

These options increase performance and also demand more from the memory controller and memories, so it can be more difficult to stabilize

[frenzyff]

I am still running bios 2007 without issues. MCR works flawlessly here. Saying its questionable might only apply to your settings.

That said. I see no reason to upgrade my current Bios. Ill do that when i get the 9950(X3D)

[roupa_de_trapo]

No one is obligated to test a new BIOS, but you run the risk of not having new features available or other performance improvements. The AM5 platform in this first generation of motherboards is still very recent and there is still a lot to evolve to take advantage of even the current Zen 4. The curve shaper is working in Zen 4 as well. Many DDR5 still depend on adjustments to take better advantage of speed and stability.

There you go

There is a memory performance regression on the latest beta BIOS
2201 - no SVM and Memory Isolation

1905 - no SVM and Memory Isolation
