[Request] Unlocked ASUS H81M-E/M52AD/DP_MB BIOS

Hello BIOS Modding Community,

I hope this message finds you well. I am reaching out to request assistance with modifying my BIOS to enable overclocking features and AI Tweaker options. I am an enthusiast looking to optimize the performance of my system, and I believe that a custom BIOS would greatly enhance my ability to achieve this.

Here are the details of my system:

Motherboard: H81M-E/M52AD/DP_MB
BIOS Version: BIOS version 0604
CPU: Intel Core i5-4460
RAM: Corsair Vengeance 16GB (2x8GB) / 1600MHz / CL9 / DDR3
GPU: Nvidia GeForce GTX 1060 6GB
Cooling Solution: Stock air cooling

Specifically, I am interested in the following modifications:

AI Tweaker Options (Overclocking): I would like to unlock advanced overclocking options in the BIOS, including CPU multiplier adjustments, voltage controls, and RAM frequency adjustments (XMP). The ability to fine-tune these settings would allow me to push my hardware to its limits while maintaining stability.

As my desktop is a prebuilt from Asus, the motherboard is locked. Despite my research, I’ve hit a dead end in enabling overclocking options. The closest solution I found,

Swapping the Bios chip out or reprogram for a MOBO H81M-E Bios version (which has OC AI Tweaker options). However, I’m uncertain about the feasibility of this method.

I understand the risks associated with BIOS modding and am willing to proceed since I have access to TL866 programmer. I am confident in your expertise and would greatly appreciate any assistance you can provide in fulfilling my request.

Please let me know if you require any additional information or if there are any specific guidelines I should follow or if you know a solution to my problem!

Thank you for considering my request.

Sincerely,
[Cosmos]

Many Asus models cross flash have been done with success, you have a programmer so get to it, the motherboard will not die if it doesn’t work. Keep a full dump/backup.
Other than that requires manual mod with AMIBCP regarding the possible and available options that can be unlock, if they are present in the bios code.
You can wait for more users contributions

EDIT: Both have NUVOTON and RTL Gigabit, i would take the chance, usually the base bios code is the same. (The M51AD had Intel Gigabit instead of RLT)

Thanks for the reply! You are right that many have done cross flash, but in this case due to the MOBO difference, I am not sure if the system will be stable. As you can see in ASUS H81M-E/M51AD/DP_MB - The Retro Web (I know its a M51AD but I cant find a M52AD) is that there is some similarities to ASUS H81M-E - The Retro Web but some that makes me question if its possible.

For visual I found this For ASUS H81M-E/M52AD/DP_MB Motherboard LGA1150 M-ITX Tested OK | eBay and what I found the only difference is a green light beside ATX power connectors 24-pin.
