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

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.

Thank you for your reply. i've tried running it with BIOS 0705, 1709 and 1807. With VDDQ of 1.4v, VDDIO of 1.39v. With various timings, and transfer rates. But nothing except 3600MHz, seems to POST. i wouldn't mind if the RAM isn't running at its full spec's, but would be nice if it could run a little faster than stock.

I updated here, but I didn't get maximum memory and clock performance, during the test 1 error appeared.

I cannot lower these timings (tRAS, tRDRD_SD/DD, tWRWR_SD/DD) more than what is shown in the image.

During testing, the system was able to save all settings correctly in the profile storage location, unlike versions prior to this 2204 which lose settings if they need to be activated to recover the previous, more stable configuration.

hi everyone,

I currently utilize 2x Samsung 990 Pro on my X670E Extreme. 

Primary drive is identified as PCIE Gen 4 x4 while my secondary drive (on Gen-Z addon card (next to sdimm) is reporting as PCIE Gen 4 x2. 

ie that correct or should I be getting more lanes? Benchmarks show 50% reduced performance compared to primary drive. If so, what should I be looking into from BIOS perspective? 

[frenzyff]

got 3x 990 Pro on my X670E-Extreme. All are correctly identified as Gen4 x4

[iamgarffi]

As they probably should. Is there a particular bios setting I should double check to ensure a limit is not place there? I’m running 1807 bios. 

[Pythonista]

I had the same problem with similar configuration ( 2 x Gen 4 NVME on X670 E-A with BIOS 1807)

for me going into BIOS and manually setting PCI-E speed for NVME 1 and 2 to GEN4 (instead of auto) fixed the problem.

[74lobster]

Sadly we can only hope that all these problems will be fixed with the next bios...

I have made adjustments but still my secondary drive reports half the speed in Crystal disk mark (3500 vs 7000 of primary drive).  

second drive is on dimm add-on card.

thoughts?

I have no idea! 🤔
