I recently moved to the MB listed in the title. It is currently using BIOS 7D69v130.
1) Should asynchronous eclk1 affect the memory clock speed?
2) I notice no difference between OC Explore Mode [Normal] vs [Expert], should there be?
3) Does anyone have a good explanation of how to use the Adaptive Mode under the CPU Ratio Apply Mode
4) I notice that power to the USB interfaces is completely removed when shutting down via windows. Can this be changed? My Lian Li fan settings have to be reapplied after shutdown. This was not required on my ASUS X670E MB.
Some suggestion:
It would be advantageous to have control of:
MISC Voltage
tREFI or Reference Interval under Memory Timing settings
These are available on other X670E motherboards
Also, I tried the latest beta BIOS(7D69v151), which now does appear to be beta, and had problems, after initial configuration, getting back into the bios. When the advance page would show on the monitor only part of the graphics was visible. While trying to make changes the bios would freeze and in most cases did not take the changes I had entered, which was extremely difficult because of the screen freezing. Needless to say I gone back to previous bios. Thanks for the dual bios feature on this MB.

Alan J T, thanks for the reply. I had already looked at this thread but had not gone thru it entirely. I just completed doing that but did not find any discussion addressing my questions. However it appears there are many issues with the latest bios, which if I understand the MSI naming convention you explained in that thread, is still a beta bios. As far AGESA 1.0.0.4 is concerned ASUS still has not released a bios with that AGESA. In fact the bios I have on my X670E Hero has AGESA 1.0.0.3A + D patch level.

Here is my system config"
CPU: 7950X
MB: MEG X670E ACE
RAM: GSKILL Trident Z5 neo RGB, GSkill F5-6000J3038F16GX2-TZ5NR
VGA: GB Aorus RX 6900XT Extreme Waterforce WB
Cooling: Optimus Foundation CPU water block, 1 420mm Radiater, 2 x 360mm radiaters
CASE: Corsair 1000D

Hello, will try to answer what I do know

1) Don't know sorry, haven't touched this option yet and don't know its behaviour.
2) Same here, Normal vs Expert OC Explore Mode no difference at all, they appear to be identical.
3) I only fiddled with it once, basically you just have to set the threshold in which the cpu switches between original stock single thread and the all core manual oc, so you can benefit from both high stock single core boost on low load and your manual all core OC, determined by the threshold setted.
4) I haven't seen an option to mantain USB power on when shutting down the system.

Agreed on MISC voltage control, it can be found under Settings/Advanced/AMD Overclocking though, but would be better to include it inside the OC section. Also would add that a GDM (Gear Down Mode) option would be very welcome too.

tREFI was included on latest 1.0.0.4 beta bios, the downside is Memory Context Restore can not be enabled or it will BSOD really badly, so you have to leave it on auto in the meantime they figure out how to make it work again without BSOD, as it worked just fine on previous bios.

1) I also haven't messed with this since I haven't had too
2) Not exactly sure the difference, but and Processor I've overclocked in the past (Typically Intel) you had to change it to Expert.
3) I wouldn't really adjust this. I'd suggest using Core Optimizer
4) I haven't seen any Desktop boards that keep USB ports active. I have a USB-C Port on my case that can be powered, but it'd take more than just connecting it to the Motherboard. I've seen several laptops have this function but nothing really Desktop line wise. I wish they did so I could charge my headset without powering my machine on.

4) Asus boards do have something called "USB battery charging support", maybe that's what he is referring to, but I don't know, just guessing.

Agreed on using Curve Optimizer instead of manual fixed frequency OC, but for people with high end custom liquid coolers maybe adaptative mode is a better option, not for me with an Arctic Liquid II 280mm though, my 7950X gets too hot with manual OC at high frequencies.

Thanks for your replies.
I bit the bullet and went back to the latest bios thinking because I enabled Memory Context Restore that it might have caused the issue I was experiencing. Started with a clean slate by performing a clear CMOS. Once in the bios made the changes I wanted to make but did not touch Memory Context Restore, left it in auto. So far so good. I was able to get into windows, check some things out then restart and go back into bios to make some more changes. The last time I tried this on this bios I would not see all of the bios advance page graphics plus it would freeze in the bios, sometimes it would unfreeze but usually I would reset from the case or MB. In any case this bios seems to working as well as v130 with the exception of Memory Context Restore. Nice to now have tREFI adjustable. Thanks to @Bloot for reminding were MISC voltage adjustment was located.

My reason for asking about the asynchronous eClk behavior is I was messing around with this feature to get some more single thread performance and thought I had a fairly stable setup but in the game I mostly play after some period of time, seemed to be around 1 hour, the game as well as windows became extremely sluggish. Evenually I noticed while I was in the bios that my memory frequency as running over 6355MHz instead of 6200MHz. I was not expecting that changing the base clock would affect the memory based on a video I watched on the Skatterbencher YouTube channel. Certainly would like some feedback from MSI if that was possible on this issue.

The what now

Will have to look into this

2) I notice no difference between OC Explore Mode [Normal] vs [Expert], should there be?

Nothing I have really noticed but I do enable it in case it opens up some extra setting in Advance Memory or CPU settings.
Could also be all ways on by Default with MSI as may be a bios option set By AMD

3) Does anyone have a good explanation of how to use the Adaptive Mode under the CPU Ratio Apply Mode

I just leave it as AUTO any other setting seems to lock the CPU to one Speed same as setting a CPU Core Voltage seems to do.
Not sure if this has changed on the 7000 series CPU

I just use Curve Optimiser of - Offset and set an Undervot of 0.1000v

Today I wanted to see if I could push Fclk to 2200MHz. Before doing that I saved my current settings. I changed the Fclk from 2167 to 2200 saved and exited. The post got stuck, so figured the setting change was not stable. I had to clear CMOS in order to get back into the bios. Once in I loaded my previously saved settings, saved and exited. However, it would not post. Ultimately, I had to clear CMOS and renter my previous settings manually. This seems to tell me that the bios setting save feature is not saving all your settings. On the previous bios I had several different settings saved and was able to switch between them with out any issue. So, this bios v151 has at least one more bug/issue.

@Alan J T , I tried bios v153 today and I am still having issues loading a saved profile after performing a clear CMOS. I will be creating a 2nd profile later to determine if I can switch back an forth under normal conditions.
What I noticed after loading a saved profile is the changes to PBO are not being saved. However, even if I go through all the various settings to check if they are set to the correct value or setting, change what needs to changed and then save and exit I was get a screen indicating failed Overclock. I then tried to load default settings and it took 3 time before the bios would restart.
Another observation regarding overall POST time. Regardless of various settings to ignore checking for VGA, disabling ASMEDIA SATA, disabling iGPU, the POST pauses at code 99 for several seconds before proceeding to code B4 where it pauses again and then proceeds to code A0 for another pause of several seconds. In bios v131 you reduces these pauses substantially, allowing for faster POST time.

Im also having the same issue.... PBO settings are not being saved with saved profiles, and iv having to write all my settings down on paper so I dont forget what was changed.

Same here with MSI x670e Carbon (7D70v12). PBO Setting is not applied from saved profile.

Msi x670e carbon

Is there any way to overclock eclk? Do we just set bclk to 105?
There are a couple concerning things here. No matter what zen 4 cpu I have used with this motherboard, I have a hard cap of 5500mhz. Why?

For the 7950x3d, msi doesn't even have an option to set frequency or prefer cache? CPPC would be the option that exists on every other motherboard on planet earth.

Why is msi asleep at the wheel

The hard cap of 5500MHz occurs when 4 or more cores are being used. AMD made this change in an earlier AGESA. Your single and dual thread boost clocks are capable of boosting higher than 5500MHz.
What I do get MT boost to go higher than 5500MHz is use the eCLK1 mode. I currently have my base clock set to 103.8MHz.
I have attached a screen shot of my 3DMark CPU Profile test results. My max thread CPU clock was 5700MHz the same for 16, 8 and 4 Thread tests. There is a youtube channel called Skatterbencher that has a video explaining how to OC by using eCLK1 (asynchronous) mode. Here is a link
hope this helps. One more thing, I am able to achieve my results thru the eCLK1 mode method but I am also direct die water cooling my 7950X. YMMV. If you decide to try this method you will notice that the BIOS shows the memory frequency increasing. Ignore this indication as the actual memory frequency is not changing.

I've seen all his stuff but you can't overclock eclk on the carbon. You can only mess with the base clock which also adds to ram and every other clock. How are you doing this on a carbon? I don't see eclk anywhere in the bios
Edit: so just change the base clock and that is eclk1? And do my CO offsets?

Same question. Does Carbon has external clock gen? The related BIOS options are lacking which let me think it doesn't even have one.
BTW, try windows "Balanced" power plan, instead of "Performance". Some cores have to be in sleep mode in order to let single core boost higher. In "Performance" mode, cores may never go to sleep.

First off I have the X670E ACE not the carbon. However the Carbon is an X670E based MB, so in theory it is capable of supporting 2 external clock generators. In my BIOS under the OC settings it has a selection called eCLK Mode. If I select that there are 3 options, AUTO, eCLK0(synchronous), eCLK1(asynchronous)modes. Not sure if your BIOS has this feature. I have attached the PDF file for the AMDAM5BIOS for MSI.

Edit: so just change the base clock and that is eclk1?And do my CO offsets? If you can change to eclk1 mode as described below than the answer is essentially yes. However, you will need to change CPU Boost Clock Override to a lower positive value or possible a negative value based on how much you have increased your base clock. For instance, in my case my base clock is set to 103.8MHz. If you multiply 5850(max boost frequency for 7950X) by 1.038 you get a max boost of 6072MHz, which would probably not be a stable value. That result is with the CPU Boost Clock Override set to 0. Again in my case I have CPU Boost Clock Override set to a negative 50MHz making the max boost frequency 6020MHz. Than I adjusted my CO values to achieve stability, which for my CPU I am running -13 CO for all cores except 2 and 6 which are currently set to 0. Not sure if this is 100% stable but so far it is working without any crashes but time will tell.

Unfortunately zero luck with 7900 XTX. Constant driver crashes… AMD has been dreadful. Ended up ordering a 4090 MSI Super Rim. I’m hoping better luck with that, replacing a 3080 TI.
