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.

Hello everyone,

I hope you’re all doing well. I wanted to provide an update and seek further advice on my project to enable overclocking capabilities on my H81M-E/M52AD/DP_MB motherboard.

Background: As some of you know, I’ve been looking to unlock overclocking options and AI Tweaker settings on my motherboard, which is originally locked due to it being part of a prebuilt Asus system. After some discussion and research within this community, I decided to attempt a BIOS cross-flash with a BIOS chip programmed for the standard H81M-E, which has the overclocking features available.

Current Status: The BIOS flash was partially successful. The system boots, and I can access and adjust the overclocking settings, which was the primary goal. However, there are some significant issues:

* The Ethernet port is non-functional.
* The system overall feels unstable and slower than before.

Conclusion and Next Steps: It appears that while the new BIOS is functionally compatible to some extent, it does not fully support all the hardware integrated into my specific model. The difference in hardware configurations between the standard H81M-E and my model likely accounts for these issues.

Given this, I believe the next best step is to modify the BIOS tailored specifically to my motherboard’s model to incorporate only the necessary overclocking features without disturbing other functionalities.

Request for Assistance: I am reaching out to see if anyone has experience with BIOS modding specifically for stability and hardware compatibility, or if someone has tackled a similar issue with the same motherboard model. Any guidance, tools, or references you could share would be incredibly helpful as I navigate this complex process.

Thank you all for your continuous support and advice. I look forward to your suggestions and hope to move forward with a solution that maintains system stability while unlocking the performance enhancements I'm aiming for.

Warm regards,
