[REQUEST] Lenovo ThinkCentre M715q 2nd Gen BIOS Unlock

[FHC08]

I recently acquired a M715q 2nd gen, and cannot unlock the stock 19w TDP no matter what I try.  Is there a custom bios that allows this?

How do you know that your TDP is 19 W?

Plan one didn't work
Plan two worked!) Thank you so much! You are a true pro!
I installed 3 gb of video memory and everything works correctly.
I wanted to overclock the RAM a bit more, set the frequency to 1600 mhz, but no change. Maybe some other settings should be changed? The performance of Vega 11 depends very much on the memory frequency. I currently have 2 2666 mhz memory cards and I wanted to overclock them to 3200 mhz so I don't have to buy new ones.

Could you share the mod? The original link doesn't work anymore.

Also, just to make sure we have the same hardware, it's a Ryzen 3 2200GE?

Thanks for the link!! Unfortunately, I seem to have the 25L8006E chip, I thought they would be the same.

I am trying to read the file with a SPI programmer but I'm having issues. I can detect the file properly and the first few hundred bytes are always identical and seem good, but successive reads always results in differing files, and most of the file is "FF" or "00".

Which programmer did you use? Did you keep the chip soldered to the board? did you plug in the PC PSU?

Hello. Is it possible to modify the bios on the Lenovo ThinkCentre M715q 2nd Gen nettop to 2Gb?
The maximum amount of allocated video memory is 512 MB, if you set it automatically, it is allocated 1 gb.
I tried changing the parameters in AMIBCP-5-02 in the UMA Frame Buffer Size section from auto to 2G, but there was no result.
Then one person on one of the forums suggested that from Boot_Shell_AmiSetupWriter line enter the command UEFI amisetupwriter 0x50 0x40 or amisetupwriter 0x50 0x00, then amisetupwriter 0x176 0x40. but the same result was no. Most likely, this limit is written in the code, and it must be sought by digging through half of the firmware
Below I attach the BIOS dump, merged by programmer

How do I use BIN to flash on 715q 2nd gen? It only flashes ROM not BIN?

@max911
1. It shouldn't be ,are you sure the command line you typed is correct ? if so ,in addition to original one command then also type this command : setup_var AmdSetup 0xDD 0x1 then test again.

2. If plan 1 is still get a failure ,now try plan 2. This is a mod of unlock advanced menus based on you provided dump.  There are two "UMA Frame Buffer Size" options on setup module. One is Lenovo custom under Devices >> Video Setup ,another one is a hidden AMI setting under Chipset >> GFX Configuration. This mod can let you see another "UMA Frame Buffer Size" option in bios ,then you could directly tune it in bios without through variable change under uefi.

I have to sleep ,it's too late now(A.M 1:22) ,go luck!


*.setup module = what you can see the menus structures on AMIBCP. On plan1 i try to let you to change "UMA Frame Buffer Size" size under AMD CBS ,this is a external module ,insert it to bios screen is difficult and i can't guarantee if i can perform it. So i let you use Grub.

You can reupload the link of method 2, I did the configuration with the code you mentioned

At the moment there are 2 ways
1. replace your BIOS with a modified one (you need a spi programmer (ch314a) + 1.8V adapter + clip or desoldering (reliable, but you need to know a little about the process))(its plan 2)
2. change the hiding of the BIOS settings through a special program booting from a USB drive, you can access and modify AMD CBS Menu without flashing, the program is called "Smokeless_UMAF" (there are fewer settings, but you can if you luck and bios posible to change hidden setting)
