X670 / X870 resource thread

[Shamino]

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

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.

1515? Where do you see that? G-Docs table does not have that listed.

Top of the page under the spoiler

[iamgarffi]

I still dont see it. How about pasting URL here? 

[UNOE]

When I look at the spoiler drop down I see 1515 and click the link it’s a x670 bios for hero and strix. I’m not seeing x870

Sadly Can't get any ram (G.Skill CL30, CL26), Corsair CL30 to boot with GDM off 😕 Win freeze on sign in despite completed post.

CPU: 9700X
Motherboard: B850 TUF PLUS WIFI
BIOS: Version 1051 (latest beta)

My PC beeps every time I press the power button.
I applied EXPO II (6000 CL30) and undervolted the CPU by -20mV.

I'm also finding EC ACPI(?) errors in Event Viewer , not sure if this is related to my Gen5 SSD bug or something else but I've never seen this before BIOS 3222 (or never noticed?). X670E-I

@andersc for the X670E-I Gaming Wifi is a new Beta Bios available.

ROG STRIX X670E-I GAMING WIFI - Beat Bios 3257

@umiumi223 for the B850 TUF PLUS WIFI is a new Beta Bios available.

TUF GAMING B850-PLUS WIFI - Beta Bios 1057

The new Beta Bios are now available on the support pages. It just varies from region to region. They are already displayed here.

Sorry for the newbie question... I'm considering upgrading my 9950X3D system to a 2x48 GB kit, and according to the official ASUS memory compatibility list for the Strix X670E-E, the only G.Skill kits that are listed have an XML profile (2 are 6400, one is 5400). I know that they would appear as DOCP in the BIOS and it should work, but I was wondering if there is any negative side of not having an actual EXPO profile.

On the other hand, the G.Skill web site lists as compatible kits a bunch of 6000 MHz kits, all with an EXPO profile, which btw happen to be more expensive.

Should I put more faith in the ASUS or in the G.Skill compatilibity list, and is there any argument in favor of the slower and more expensive EXPO kits?

[UNOE]

I bought a 6400 cl32 xmp profile kit with no expo profile for $175 open box 2x32 1.4v because it was cheaper.

i wasn’t able to run 6400 cl32 unless i ran it in 2:1 mode. Mainly because some AMD CPU can’t achieve 6400 mclk uclk1:1, like mine can’t. 
So that’s why your not going to find many expo kits or support page showing above 6400.

i ended up running mine cl28-36-36-36 at 1.48v for 6200 or 1.43v for 6000.

took time to find a stabilize the settings but I’m glad I went that route learned a lot of what the ram is capable of and it better than expo with tighter tRAS.

if you don’t want to go through the work I would stick with a 6000 kit. Because there no guarantee you can do 6400 1:1 with AMD.
