Hi, @Lost_N_BIOS

I am wondering if it's possible to enable following items on v2.50 BIOS of ASRock B85M Pro4. I've tried "USER" method but it didn't work.

Non-Z OC
Multicore Enhancement
CPU Ratio, (All Core, 1 2 3 4)
CPU Cache Ratio
CPU OC fixed mode
Filter PLL Frequency
Internal PLL Overvoltage

I see all these items under OC Tweaker when viewing 2.30 version of the BIOS with AMIBCP. But not on 2.50. I am not sure if it's even possible to enable them on 2.50.

@NeverMore - As I answer you, I have not looked at either BIOS file, but based on your comments it sounds like I don't need to look.
If you cannot see those items you quoted in 2.50 when viewing with AMIBCP, but you see them in 2.30 BIOS, then they are removed from 2.50. Best to stick with 2.30 BIOS if you need those, and update this BIOS with whatever else you want updated inside it.
What did you try "User" on if nothing there?

* Edit, I checked, as mentioned above = answer

Good time!
I really need help!
I purchased the motherboard ASrock B550 Phantom Gaming 4. There is no parameter in UEFI to disable AMD PSP.
ASrock said in a personal letter that starting from AGESA Combo AM4 1.0.0.0. AMD has removed this feature.
I have the BIOS of my board, opening it through AMIBSP5, in the BIOS Strings tab, I see this parameter.

Is it possible to disable it or return it to the menu?

If this is not possible, I will change the platform. Unfortunately, under Russian law, I can return the equipment from the without obstacles within 7 days.

Thank you in advance for your reply!

@bl0w - Strings tab is only for language file and reference usage, it may contains stuff that was never in your BIOS, sometimes they are lazy and leave in strings due to using base BIOS with those settings in it or previous BIOS w/ removed but left in strings.
Please link me to the BIOS download page for your board, and tell me what BIOS version you are using, I will check and see if the setting is still there and just hidden, and if hidden from you I will make visible again
If they are being honest with you, then the setting may not work anymore with that Agesa

Probably removed due to security issues, backdoor hacking etc, that's all I see when I google AMD PSP

Hi @Lost_N_BIOS Same question as the posted. I extracted the bios and I see an unnamed folder in under the Setup -> Main. The folder has no name but contains so many lines I couldn't check them all if there is a PSP option. is there a way to search for the PSP or show this menu for more convenient work?

My Bios is dlcdnets.asus.com/pub/ASUS/mb/SocketAM4/PRIME_B450-PLUS/PRIME-B450-PLUS-ASUS-1820.zip

@Lost_N_BIOS Tried following your technique to find the hidden menu by hex but cant seem to find it to enable the menu. i have set the hidden menu to user but only the hex part i am having difficulty in finding. Here is the bios dump from my laptop.

oh dang thought he was still active. oh well if anyone can help i would be grateful if they can take a look at the file.

Hi @Lost_N_BIOS I'm very new to this Bios Modding community and I'm facing the same issues with this VarOffset 0xFFFF and VarStore 0x0. Is there any solution to this? Actually I'm happy enough to get my laptop able to run ThrottleStop with the FIVR function for undervolting enabled through some bios mod. My main concern for my laptop now is Fan Control. After dumping my bios and searching through everything about Fan Control I came to all this VarOffset 0xFFFF and Varstore 0x0 which is impossible to mod it. I've tried using Phoenix Tools but I can't even open the dump file. Same if I use Amibcp I can't open the dump file either. I really hope there is a solution to this. Cheers!
