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.

Level 7

strix x670e-e has bios 1416 out now which includes the qvl 48/24 ammendments

Did you test the new bios? It is good?

If you’re looking for GamersNexus level of testing then no 🙂

Thus said, voltages are in check, Expo, PBO and MCR working and stable for me. 
2x32 G.Skill 6000-CL30. 

can I ask you for your MCR settings with those ram sticks?

Level 9

Is it common knowledge and confirmed by now that no 4 sticks of memory will run at full speed with this MB? I need 128GB / 192GB. I know that the latter is a pipe dream - I have 4 that are running at 3600 ugh... 

Dual ranked RAM won’t run at full speed with 4 sticks.
Limitation of memory controller. Not limited to this board. 

I thought both Intel and AMD made that clear. 

Yeah, but but... 3600 is truly pathetic 🙂

Speed or Capacity. Pick one.  You can’t have both 😈

do you really need more than 64G total ram? 

I am running 192GB at 5200MHz. DOCP1 profile, X670E Hero on 1003.

Can anyone confirm this config is now stable on 1415?


Which memory kit are you running?
