I am using GenSMBIOS-master.

I have tries a few and can get the Smbios name to change in "about this Mac" but still states at 3.7GHZ.

I have attached the config that gets the full 5.2ghz but with this I cannot get a serial to work.

Just says "default string"

Is there any workaround for this?

What are you referring to cannot get a serial to work? Do you mean a Serial isn't being displayed in About This Mac and System Report or your iServices fails to work?

Yes correct, when I use the config with custom smbios no serial is displayed in about this mac and iservices fail to work.
I do however get the full speed of 5.2GHZ with my processor.
Have you ever heard of this issue before?

No, never. Use OCC to generate the proper SMBIOS or use the following code and replace with existing ones in your config.plist. Use a text editor.

Okay tried that. Still the same issue. Have tried

-copied the above text and pasted. Same effect
-tried new serials and SMBIOS with GENSMBIOS-Master, Opencore configuration and also copied and pasted details across from Clover

Still no effect. The core max frequency is capped at 3.7GHZ

I only have one 16gb ram stick. I was thinking that would be an issue but it the same with two 16gb sticks in all different slot variations.

I really am baffled. I downloaded a few golden build EFI's, every one of them seems to have the same issue. with my cpu being capped at 3.7GHZ unless I put SMBIOSCUSTOMMODE to "Custom" and Kernal - Smbiosguid enabled in kernel quirks. Then I get full max core and freq range of up to 5.2GHZ.

With the above data, is the Serial issue fixed?

Thanks for the additional info.

Once you're done editing with the config.plist, save that and delete all the files from the directory Library/Preferences/SystemConfiguration except for "com.apple.Boot.plist" file.

Empty trash, reset NVRAM twice and then report.
 
I tired the above.

Also no success.
the system boots and has the attached details now in about this Mac. I am still capped at 3.7GHZ

Delete the system config files was a good shout. Really thought that would of fixed it but no luck unfortuentyl.

Id like to put it down to hardware but the fact it works with one config file and also fine in Windows means its has to be something with the SMBIOS?

This isn't correct at all. Comet Lake is natively supported and it should have all the details. Attach the last EFI to check further.
 
Okay. I got it! Sorry for my late reply. Spent the day with my friend who is quite more experienced than me at these builds.

We tried various different methods and configs but finally tried a clean OS and straight away it started to work. Could heard the fans ramping up when the turbo boost kicked in during the installation. Should of tried that initially thinking back when I tried a few golden build EFI’s and they were still causing issues.

Very strange as from my understanding it’s a sealed system but I guess along the way something must of got messed with.

Everything is working great now!

Still hoping for a fix for the limitation with thunderbolt interfaces and network features. If you need any tests done on my board I’d be happy to help.

Keep up the awesome work you guys.

As per my experience, on Mac, when trying several fixes, sometimes it fails and the only way is the clean install.

Glad that you got it working now!

Thunderbolt limitation or Thunderbolt Interface limitation? Of course, you can now write a guide ;)

Thank You, cheers!
 
Sorry, thunderbolt interface limitation is what I meant.

Love if I could use both my ram sticks and also use my native WiFi card to have airdrop and continuity without having to worry about it disabling network features due to the ‘Disable IO Mapper’ quirk.

If I could help in anyway let me know guys.

Thank you once again for your help and well detailed troubleshooting. Learned a good bit more from this issue.
