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

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)

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.

I always bought Asus mainboards, but now I'm a bit (a lot) sketched out.

Does any of you fine gentleman know if 2x 48GB modules @3200 (pc6400) and CL32 would work on the most recent BIOS? If not, then i'll say my goodbye's to anus, a couple months is too long to fix something which must be working out of the box.

No AM5 boards are guaranteed to run RAM at 6400. This is not an ASUS thing, it’s an AM5 thing. Think AMD’s spec is 5200 for 2 sticks, anything above that is overlocking and not guaranteed to work. You should be able to run 2*48 at 6000 and if you put a lot of time/effort in maybe get 6200 but it’s probably not worth the effort.

Thanks for the reply!

Do you happen to know if they would work on the most recent BIOS as well - or did Asus re-add support for 24/48gb RAM? Since theres no 24/48GB modules on any of the compatibility lists of the mainboards, im a bit worried.



New Bios !510 it works's ok

ROG CROSSHAIR/STRIX X670E Series Beta Bios 1510

1) Update to AGESA 1007a patch A
2) Update ROG logos for visual identity
3) Improve system performance

I bought of the most expensive motherboards & CPUs on the market because I like wasting my time with a new bios every other week that doesn't work half the time. So many people are having issues, and no one knows who's to blame (Memory, Motherboard, CPU, Bios) and I have a feeling that's the business strategy. AM5 is the worst platform I have ever used in the last 20 years. I'll be switching back to Intel once I save up some money and never buying another Asus product again.

I feel you, but I dont think its AM5 - its Asus. Nobody can even tell me if 2x 48GB modules would work on the most recent BIOS. Gigabyte and MSI both list 48GB RAM modules in their compatibility list. It's just old Asus who cant can again.

You'd really need to elaborate on that. 48GB DIMMs are supported, so what are you looking for clarification on?
