[BUG] Reported processor speeds are incorrect on some machines.

[AcatXIo]

General description of the bug:

• What happened:
  I noticed that Fastfetch shows either the turbo or the regular processor speed depending on which machine I run it on; in one case, the reported speed was totally incorrect.
  Tested machines (first 3 run Windows 11, and number 4 runs Windows 10):
  1. Toshiba Satellite P755 with Intel Core i7-2670QM:
     • shown speed: 3.8 GHz (♦️totally incorrect)
     • processor turbo speed: 3.1 GHz
     • processor regular speed: 2.2 GHz
  2. Dell Latitude 5490 with Intel Core i5-7300U:
     • shown speed: 3.5 GHz (🔷correct turbo)
     • processor turbo speed: 3.5 GHz
     • processor regular speed: 2.6 GHz
  3. HP OMEN 15-ce0xx with Intel Core i7-7700HQ:
     • shown speed: 2.81 GHz (🔶correct regular)
     • processor turbo speed: 3.8 GHz
     • processor regular speed: 2.8 GHz
  4. HP ProBook 6460b with Intel Core i5-2410M:
     • shown speed: 2.3 GHz (🔶correct regular)
     • processor turbo speed: 2.9 GHz
     • processor regular speed: 2.3 GHz
• What should happen:
  Fastfetch should tell the user which processor speed it is showing: the regular one or the turbo, and the speed should be correct.
• Fastfetch version used: 2.10.2 (x86_64).
• Did it work in an older version: No.
• Where did you get the binary: From Scoop package manager for Windows.
• Does this issue still occur in the latest dev build: Yes.

SMBIOS sometimes reports incorrect max CPU freq, especially in some old platforms. Please try this: #800 (comment)

Can you try this ( assume Hyper-V / WSL2 is not enabled in your laptop ): https://github.com/fastfetch-cli/fastfetch/actions/runs/8860739281/artifacts/1453433558

Oops. Try this please: https://github.com/fastfetch-cli/fastfetch/actions/runs/8860844348/artifacts/1453449229

@Null-Ping @lostdusty Can you also test it?

[AcatXIo]

With new one (first is the CPU line from fastfetch.exe, second is frequency part from fastfetch.exe -c ci.jsonc --format json):

CPU: Intel(R) Core(TM) i7-2670QM (8) @ 3,80 GHz
"frequency": {
	"base": 2.195, <- correct
	"max": 3.8, <- wrong, should be 3.1
	"min": null
}

CPU: Intel(R) Core(TM) i5-7300U (4) @ 3,50 GHz
"frequency": {
	"base": 2.7, <- correct
	"max": 3.5, <- correct
	"min": null
}

CPU: Intel(R) Core(TM) i7-7700HQ (8) @ 2.81 GHz
"frequency": {
	"base": 2.808, <- correct
	"max": null, <- should be 3.8
	"min": null
}

CPU: Intel(R) Core(TM) i5-2410M (4) @ 2,30 GHz
"frequency": {
	"base": 2.295, <- correct
	"max": 2.3, <- wrong, should be 2.9
	"min": null
}

Apparently the only change is 2.712 being rounded to 2.7 for i5-7300U?
I double-checked to use the new version, but I'm not 100% sure if I'm doing everything correctly.
Does Fastfetch have some caching or something?

[CarterLi]

You didnt have WSL2 / virtual machine platform enabled right?

[CarterLi]

According to https://stackoverflow.com/a/39620056, the method is only supported in Skylake (6th gen) and later. Its expected no change for old cpus

What strange is 7700HQ

[AcatXIo]

You didnt have WSL2 / virtual machine platform enabled right?

The laptop with i7-7700HQ is not a VM (nor are the others), but I had virtualization enabled in its BIOS; after I disabled it, Fastfetch now shows:

CPU: Intel(R) Core(TM) i7-7700HQ (8) @ 3.8 GHz
"frequency": {
	"base": 2.8, <- correct
	"max": 3.8, <- correct
	"min": null
}

So it now works correctly, but why does it depend on disabling virtualization in BIOS?
I had it on because I sometimes use Android emulators.
Is it possible to make the speed be detected correctly regardless of this setting?

[ghost]

@Null-Ping Can you also test it?

Sure!
The results are as follows:

CPU: 11th Gen Intel(R) Core(TM) i3-1125G4 (8) @ 3,7 GHz

"frequency": {
  "base": 1.2,
  "max": 3.7,
  "min": null
}

Everything is correct, but I also had to disable virtualization like AcatXIo did, apparently my laptop had it on by default.
Before I turned it off the results were:

"frequency": {
  "base": 1.19,
  "max": null,
  "min": null
}

[lostdusty]

@lostdusty Can you also test it?

Nope, sorry (I'll be away from my pc/home for about ~2 weeks, or maybe even more). But I have both virtualization and VT-x enabled. Also my processor is from the 7th gen, just like the i7-7700HQ.

I guess virtualization features makes the smbios report the wrong frequency, even if it shows the right one in bios.

[AcatXIo]

I guess virtualization features makes the smbios report the wrong frequency, even if it shows the right one in bios.

I tested, and the SMBIOS for i7-7700HQ with virtualization off is still the same:

Max Speed: 8300MHz <- should be 3800 MHz
Current Speed: 2700MHz <- should be 2800 MHz

So the virtualization setting likely doesn't affect the SMBIOS data.

[CarterLi]

You don't need to disable VT-x / AMD-v in BIOS, and it's recommanded to enable it to get better VM performance.

You need to disable Virtual Machine Platform in Windows Features ( note WSL2 and WSA use that )

This feature has negative impact on performance. Microsoft suggests disabling it.

[CarterLi]

I think this is the best result that fastfetch can get as for now. SMBIOS still seems ok for people uses WSL2 on newer CPUs ( like me ) so I want to keep it.
