X670 resource


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:
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
Detailed Explanation on CState Boot Limiter

Test BIOSes:

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

DOCP/EXPO Tweaked: (for simple timings tightening)

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.

Looks like they're going through the motions, in that case. If it's been validated then they've had it working - that much is a known quantity. At the risk of repeating myself, you're not being ignored.

i have this ram AXU6000C3032G-CLARBK that is similar at AXU6000C4032G-CLARBK  for you is ok if i put this ram in the hero and why in the Hero or meg ACE there is not support of XMP (but i don't know if DOCP is similar of XMP) and in the Gigabyte/Asrock there is that support of the XMP?

And if i buy one network card 10g is good idea?Because the board have one 2.5g!!!

Hey, XMP/EXPO is not that relevant if the kit is present on the motherboard QVL. I'm assuming you mean AX5U6000?


13900KS / 8000 CAS36 / ROG APEX Z790 / ROG TUF RTX 4090

yes i mean AX5U6000C3032G-CLARBK  sorry!!!


"While that doesn’t universally translate to better performance everywhere there are plenty of applications in which you will see a benefit." - Which applications, in particular? Maybe for graphics rendering, I dunno. If this is what you do for living, then it may be important for your job. But hardly for gaming, which both AMD and Intel brag how much they care about when designing their new platforms. So in my opinion, very few people will see the benefit of higher memory frequency except in very specific scenarios. Maybe the next Zen generation will be able to work in 1:1 mode at those frequencies and then it would make more sense.

Also, add the dollar value to this. If I have to pay 20% more to "overcome the latency hit of 1:2", it just doesn't make any sense to me.

But of course, anyone is free to choose what makes him/her happy. I just want to say that the higher memory frequency is not necessarily what will squeeze the last few per cents of performance improvement from your system (with very few exceptions).

Aside from that, I quickly checked the QVL for one of the more common Asus mobos, X670E-E, and it doesn't list any memory kits above 6600 so perhaps  anything above this speed is not officially supported. But I haven't checked the QVL of other vendors to say if it is any different.

Best performance is almost certainly still found in "1:1", yes.

Level 9

one question the wifi module  inside the x670e hero is removable?


ok thanks ah is stable now the x670e hero now?Another question why asus/MSI x670e hero has not the support of XMP respect of Gigabyte/asrock that have support EXPO/XMP in the am5 motherboard?
