But changes are made at least?alexander1986 wrote: ↑26 Apr 2021, 04:39Rallaz wrote: ↑26 Apr 2021, 04:21alexander1986 wrote: ↑26 Apr 2021, 02:49
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...
well, I would lean towards that the changes are made and it is likely that it actually works, now the only question is, does the changed settings actually affect your problem or not?
in this thread alone there is several users saying conflicting information, some say for them spread spectrum settings did difference, some say it did no difference at all, like chief says EMI issues is complex and difficult scenario with many different causes and symptoms,
for example chiefs posts here:
viewtopic.php?f=10&t=8532&start=20#p66399
and here:
viewtopic.php?f=10&t=8532&start=30#p66426
are good to keep in mind about how complex this issue is..
so it is possible it will work in some scenarios and give better EMI resistance with manipulating these values, while for others it maybe doesnt really change anything noticeable, probably depends on nature of the EMI problem and how heavy it is etc..
probably the only way to test is if you have a day when the issue is really bad and the mouse is super heavy/floaty or whatever the symptoms may be in your case, and then start manipulating these values and try different combinations of settings of the rfi/pcie spread spectrum and icc spread% setting? to see if some combination of settings actually does any change for you...
the guy that started this thread, at least swears it worked for him to improve a lot, not 100% fixed but he said its something like 70% good now compared to very bad before the changes, so IDK, is only really you who can tell I guess..
another thing u could test maybe would be, instead of changing unhidden setting like DRAM speed, try finding some setting that is hidden , maybe like the HPET setting *if* that is hidden in your bios by default, change it with SCEWIN, then export+import and see if you can confirm the HPET setting is enabled/disabled with some program that checks timer performance/settings etc,
like for example TimerBench: https://matthias.zronek.at/projects/timerbench
( dl link for program: https://www.overclockers.at/downloads/p ... %201.5.exe )
so for example if you have HPET hidden in bios by default at enabled value, you could try disable with SCEWIN exported settings, then import with SCEWIN and then use TimerBench to compare before/after result to see if the timer actually changes,
although maybe this is bad example to test because I know HPET can also be controlled from windows via bcdedit /set useplatformclock yes/no or true/false for example, am not 100% sure but I think you should see a difference in TimerBench just from enabling/disabling HPET in BIOS without touching windows bcdedit settings...
could also try to figure out some other setting that is hidden in your bios that u could confirm afterwards if it is actually changed or not after you import with SCEWIN, etc...
only you can tell I guess how your mouse and system feels when its bad/good and if these settings can affect it or not..
but please update here with results/info if you find something you really think has changed and works for you, or if there really is no difference for you with any combination of settings, I guess nobody here can tell you anyway exactly what your problem is or what the cause is, but like I always say if your hardware like pc+monitor works perfect at other place , if you can test at friend/family place and it works 100% perfect there all of the time, then its safe to say something at your place is making it work bad, and thats the best way to test this EMI stuff I think...
at least that is how I confirmed I have this problem since it started about ~3years ago for me after a power blackout in my area, my pc+monitor works flawless and feels amazing when I tested at my fathers place for example many times, and here at home have issues with input lag coming and going, even if I disconnect *everything* in my apartment from power except pc+monitor,
only problem now like I said for me to test this settings is the past ~6-7 days have been perfect while my neigbhbour is on vacation xD so I suspect he uses something that affects me as well, as we live next door to eachother wall-to-wall so maybe we are sharing powerline or some shit, IDK.
But try some experimenting ! and report results when you have time+energy to test all this stuff IMO
