X370 Gaming Pro Carbon Downclocking CPU Multilpyer
« on: 10-October-17, 17:22:34 »

As stated, I am having issues with maintaining and setting my CPU multiplier to a certain number. For instance, I can set a voltage such as 1.3V with a multiplier of x38.00 and boot into windows and validate that it is set to that voltage and multiplier; however, if I set the voltage up a notch (1.3125V) I will boot into windows fine, but the multiplier will change to x36.00 and the voltage is correct. Is there anyway to change this? I know with my memory, there is a setting that will allow you to set multiple reboots to try to boot at a specific speed, but I am not having instability issues when change the multiplier and boot. If I go into the UEFI and check the multiplier after saving and exiting, it is set to what I want; however, if I exit and continue to windows, it just goes down to x36.00. Anyway, if anyone has any suggestions or know what is going on, please let me know.

Version 1.80 according to Command Center, 7A32v19 is the actual name. It is currently the latest "official" version.

7A32v19 is version 1.90. 1.80 would be 7A32v18. So what version do you have? If 1.80 update to 1.90.

All right, after looking again Command Center says version 1.80: 
However in the UEFI, it reports version 7A32v19 is installed: 
This was kind of puzzling to me, so I decided to clear CMOS and see what happens. Anyway, after that it reported version 7A32v18 being installed, which matched what Command Center had to day, so I re-flashed the BIOS and here we are on version 1.90. I am still having issues with Windows keeping my overclocks, as you can see in that last picture I have it set to 3.8GHz at 1.3Vcore, which I validated as stable, now, I cannot seem to validate 3.8Ghz in Windows, but it is set to 3.6Ghz instead. I have tried rebooting and checking, it's right in the UEFI, but not in Windows. The memory also seems to down clock to 2133Mhz in Windows as well.

When I try settings that are not acceptable to my hardware, CPU and RAM, the system allows my computer to start up at the standard settings.
It does not tell me what was wrong with my settings and the bad settings are still present when I return to the BIOS.

When I get my settings "better" or acceptable to my hardware, then the computer starts up and I can see the improvement.
It took a long time to arrive at the current combination, but now my computer at a 1600 runs at 3.825 reliably and when I play around with settings can get 3.85, but I think my hardware is more stable at 3.825.

The RAM is also tricky. I found "try-it" at 2933MHz 14-16-16-16-34-69T 1TrC to be reliable.
I cannot get 4 sticks of 3200MHz to run full speed.

Still I am happy with this performance.

The short comment, I think your hardware if fine. Read the posts in the overclock forum, try some new settings. See what you can get to "stick"
Good Luck

I can't see any picture. Where is it?

All right, I figured it was something like that with Windows, so out of curiosity I booted into Ubuntu and it was reporting the clock speed set in the UEFI, unlike Windows. Also, the pictures were just screenshots of what versions were reported and where, I will post them again below (If they will actually post this time):

Disable Core Performance Boost and XMP and retry.

flobelix,

Could you direct me to more reading on when to use Core Performance Boost as AUTO and when to try DISABLED?

Or, could you give a short lesson?

This is solely to troubleshoot the OP's problem nothing else. The setting controls Precision Boost and XFR. Normally it should not matter when all cores are used anyway. But this is a try if it (like XMP) troubles oc staying enabled in this case.

Just out of curiosity, I changed Vcore to 1.3125v and found that XMP was working how it should, and that it was running at 3.8Ghz 2933Mhz respectively. I will try setting in these memory timings and clocks manually, and will disable that Performance Boost option. I also saw under the OC form for these chips that one person is having an issue just like this, and apparently it is a "known bug." I will post a picture of that conversation as well as update you on what happens when I change those settings.

Ok, settings were changes as stated and we are still running at 3.6Ghz within Windows at 1.3v. That specific clock speed is interesting to me because it is not the base clock, nor the rated boost clock. Anyway, looks like the simple solution as suggested is to up the voltage 1 step in order to achieve both my desired clock and memory speeds. If you have any other suggestions, I  can try them, but for now I will live with the higher voltage. I still believe this is a bug, because on an older bios version I did not run into this issue (It was the original beta bios with the updated AGESA code). Also, here is what I saw under this AMD AM4 Ryzen Overclocking Guide (X370 and B350)

That post is 6 months old. Those problems were fixed months ago.
It is not the same or related. I would report it to MSI directly. See : >>How to contact MSI.<<

Ok, just looked very similar with the voltage offsets being the exact same to get it work. thanks for the link.

This will be the final post I make to this topic. Anyway, today out of pure curiosity I changed my "latest release bios" which is 1.90 at the current time. I flashed to version 1.97 to see if this "bug" was fixed; and indeed it was. I am able to run my 3.8Ghz overclock at 1.3V, just like I had it back when version 1.70 was the latest, but now I can actually run my ram at 2933Mhz, the actual rated speed of my kit. This issue was indeed a bug, however I did not get confirmation when I contacted support. What I was told was along the line of "we do not help with overclocking issues" even though this was an issue with the UEFI, not my CPU's capabilities of which I know the boundaries of. Thank you for all of the responses; especially that suggestion to bump up the voltage by another step, that solved my issue for the time being.
