Seems that SMBIOS reports some invalid data. Can you please try this program and upload its output?

If necessary, I can also rollback my bios.

Work around #800

Big thanks for your kind help! But you don't need to do that.

I have made a work around ( assume that @KunYi and I implemented SMBIOS detection code correctly ). Please test if the latest dev build work for you

maybe check https://devblogs.microsoft.com/scripting/use-powershell-and-wmi-to-get-processor-information/ first and use script to check SMBIOS information first

CarterLi · 2024-04-21T15:49:17Z

@KunYi WMI won't report max / boost CPU frequency in newer system (Win10 or newer), only base frequency.

Get-WmiObject Win32_Processor | Select Name,MaxClockSpeed,CurrentClockSpeed

Name                                 MaxClockSpeed CurrentClockSpeed
----                                 ------------- -----------------
12th Gen Intel(R) Core(TM) i7-12700H          2700              2700

There are only two known methods to acquire max CPU frequency without admin privileges: fetching SMBIOS data or using x86 instruction CPUID. SMBIOS sometimes reports incorrect data. CPUID is only usable in x86 platforms but doesn't work if Hyper-V is enabled. Neither seems reliable.

KunYi · 2024-04-21T15:59:30Z

Yes, the SMBIOS (System Management BIOS) Table is filled by the BIOS code. So, if the BIOS provides an error related to the SMBIOS, the WMI (Windows Management Instrumentation) code merely reports the SMBIOS information to check the status reported by the BIOS.

Perhaps you can ask the motherboard or computer vendor to fix these issues.

The WMI is for vendors to identify and address duplication issues.

CarterLi · 2024-04-21T16:13:48Z

No. Microsoft said WMI uses data from SMBIOS, but it doesnt. WMI reports everything as base freq (2700), while SMBIOS reports correct data (4700) in my laptop.

KunYi · 2024-04-21T16:23:07Z

okay, maybe to try RWEverything for check SMBIOS
you can get it from http://rweverything.com/download/

Thanks for your information. So that SMBIOS does report 8300 MHz

Let's close this issue for now. If more people report the same issue, I will remove the method of SMBIOS detection code

CarterLi · 2024-04-22T01:34:19Z

Note that the default information displayed by fastfetch was designed for linux and may not be useful for Windows. Fastfetch supports a lot more features than neofetch and winfetch. You can find information you interests in with fastfetch -c all.jsonc

Note this only works when Hyper-V is not enabled Ultimately fixes #800 #812 #815
