Has anyone tested if this tool works?
SCEWIN_64 <- admin rights
EXPORT.bat <- admin rights
changing settings that you want..
then using IMPORT.bat <- admin rights
My Motherboard is: Asus Rog Maximus XI CODE (Z390)
Edit:
or does it only works with specifics manufacturers?
Since I cannot tell if @blackmagic used a modded bios from another user that used AMIBCP
I am not expert but I can say one thing, SCEWIN is legit tool, its made by AMI the guys who make the BIOS in many motherboards today, but then its up to the manufacturer of motherboard like Asus, MSI, etc to add/remove/hide/unhide features in BIOS from the end-users.
official documentation on SCEWIN and the export/import function here from INTEL version of the utility:
https://downloadmirror.intel.com/29468/ ... _Guide.pdf
if you compare that documentation to the import.bat / export.bat you will see its legit, and it does work to reflash from windows since it has possibility to update the NVRAM/UEFI (BIOS) from windows,
however, I think still some features and BIOS settings can be flagged as unchangeable / hardlocked so you wont be able to change with SCEWIN import.bat, and in that case is where you need some modified and unlocked bios like on the other forums where I saw your post also (winraid etc)
But, in your case , you have asus rog maximus motherboard, this motherboard has BIOS USB recovery function right? so you can recover with original bios file from USB even without booting to USB? just put in the special BIOS usb port and start recovery? if you read your motherboard manual I think there should be function like this, in other words you should not have anything to lose by testing?
of course, everything on your own risk, but im pretty sure rog maximus boards have BIOS recovery function like I am talking about in situations where power failure happens during flashing or corrupt bios file or whatever...
if you decide to run SCEWIN import.bat please update us with if it worked etc and if changes are actually saved after, because I think with SCEWIN you cant unlock/unhide menus in bios , but maybe u can atleast change the default hidden settings to new values, even if they will not show up in BIOS menu afterwards... (and then you could run export.bat after to check if your new settings are really saved/enabled etc)
I did what you told me to do, tried since my BIOS has a recovery feature.
I IMPORTED the settings I changed. Everything booted into BIOS fine and it booted into windows fine.
I could not find the settings being displayed in the BIOS anywhere.
I exported the settings once again using SCEWIN_64 and it had changed every setting I actually changed from the settings when I used IMPORT.bat.
So I guess the settings are changed? But do they have any affect or do they not exist on my motherboard?
Nice that SCEWIN works for import, very good info to know !
Is hard for me to say 100% if it has any real effect or not, only you can tell I guess by testing stuff to confirm?
(so far I did not test SCEWIN myself to import changes, only export, and also my EMI problem has been minimal / mouse feels perfect last ~6 days, and I noticed my neighbour is on vacation this time also, so I have now theory that maybe something my neigbhbour is using is causing perhaps EMI for me lol, when he is back and if problems come back for me, I will test these rfi/pcie spread spectrum + ICC spread% settings to see if it actually make any difference for me)
but for example, if you make same import/export process again but with some other setting, some "normal" feature that is not hidden like maybe set ram speed to 3000 mhz instead of for example 3200 mhz (or whatever you currently use) and then you can see if it really does change ram speed etc?
for example I use 3600mhz normally on my ram :
but if I wanted to test if my export changes are really saved, I could put * on 3000mhz instead (just example) and export + import then see if ram speed actually change to 3000 mhz from 3600 mhz, etc etc.
I think a lot of features in motherboard is available and can be changed, but manufacturers decide for different reasons to hide/unhide some menus, for example on non-WIFI motherboard there is no reason to put WIFI settings, etc, and for some cheap motherboards they hide some features, but on higher price motherboards they unhide features, etc...
also probably is easier to have a general bios file for all models and then they just hide/unhide features instead of creating 100 bios versions for 100 different motherboards etc u know? at least this is my theory..
maybe some settings will have no effect, maybe some will, but I have feeling when it comes to things like pcie spread spectrum + rfi spread spectrum and ICC watchdog timer things, this is available in all motherboards because it is basic function of intel chipsets and cpu... also RFI spread spectrum setting I read is required by law in countries like USA to be enabled, for some compliance reasons with EMI emissions etc... so I think these spectrum settings + icc watchdog settings are supported by all intel chipsets/cpus as it probably is necessary functions,
just my theories... now is up to you to test different combinations of RFI/PCIE spread spectrum settings + also maybe this icc watchdog/spread % setting to see if it really helps your problems u know?
I would test myself but because I have no problems for last ~6 days with EMI and mouse feels great for me right now, I can not see if it will work or not right now...
