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
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.
Solved! Go to Solution.
On my X670E Creator the bottom PCIe slot rarely detects a card. The M.2 slot that shares bandwidth with it does so too. Is this a BIOS bug, or is there a setting I'm missing? I need these two slots to work or my computer is useless.
Well, even if I only plug one device in, it isn't being detected, on every boot. For example: I have a Blackmagic Decklink Card, which I put in the 3rd PCIe slot. Sometimes it gets detected and runs at PCIe 2x (which is fine for me), but most of the time, it doesn't get detected. If I put it in the second PCIe slot (and therefore halving the bandwidth for my GPU) it gets detected everytime and runs at 4x.
I want it to run at 2x in the 3rd PCIe slot.... I wonder if this is a bug or what the issue is?
Have you gone into the BIOS to enable the configuration 2 for last pcie slot? Sounds like otherwise it is auto to default.
Setting should be under ADVANCED tab, ONBOARD DEVICES CONFIGURATION section. There you should have to the option to select the bifurcation mode you need for each PCIE slot.
Hope this helps!
(Bifurcation configuration table from your x670 ProArt manual)
I don't have anything in the M.2 slot and my Elgato card is only detected from the cold reboot. Not critical for me - I got an external hmdi to usb card, but it's annoying - you pretty much lose the PCI-E 4.0 slot there after a sleep or hibernate.
