ASUS ROG Ally Levels Up with New BIOS: Unleashing Gaming Power & Glare-Free Delight!


ASUS, the renowned technology company, is known for producing high-quality gaming devices, and one of its popular offerings is the ROG Ally. The ROG Ally is a gaming handheld that has received positive feedback from the gaming community for its performance and features. To further enhance the device's capabilities and address certain issues, ASUS has recently released its fourth BIOS update, BIOS 323. While this update brings several improvements, it does not include a fix for an ongoing MicroSD card issue that has been officially acknowledged by the company. In this article, we will delve into the changes brought about by BIOS 323 and the current status of the MicroSD card problem.

BIOS 323 Changes and Enhancements

The latest BIOS update, BIOS 323, introduces several changes aimed at improving the overall user experience with the ROG Ally. These enhancements encompass both hardware and software adjustments that cater to different aspects of the device.

1. 30 W TDP Support for Third-Party Chargers and Docks

ASUS has included support for 30 W TDP (Thermal Design Power) when using third-party USB-C docks and adapters with the ROG Ally. Prior to this update, users faced an issue where certain third-party docks restricted the device from accessing its full 30W Turbo mode, even when connected to high-wattage USB-C power adapters. The problem was attributed to the way certain docks allocated power to the device, limiting its capabilities.

The new BIOS change rectifies this issue by allowing the ROG Ally to draw power based on what is available from the dock. As a result, when using high-powered chargers, the device can now seamlessly access the 30W Turbo mode while ensuring that the battery remains charged. However, it's worth noting that if a user connects the ROG Ally to a charger that is not powerful enough, they may still get 30W Turbo mode, but the battery could experience slow drainage. In such cases, replacing the dock and/or charger with ones capable of higher wattages is recommended.

2. Reduced Glare in Lowlight Conditions

Another notable improvement in BIOS 323 is the reduction of glare in lowlight conditions. ASUS achieved this by lowering the ROG Ally's minimum panel backlight from 25 nits to 10 nits. This enhancement enhances the user's gaming experience by minimizing distractions caused by excessive glare, especially when playing in dimly lit environments.

3. Optimized Performance in Performance Mode

Performance mode is a critical aspect for gamers, as it allows the device to deliver its maximum capabilities when plugged into a power source. With BIOS 323, ASUS claims to have optimized performance in Performance mode, ensuring that gamers can enjoy smooth and responsive gameplay.

4. GPU Memory Assignment Stability

Before the update, some users reported that the amount of memory assigned to the GPU would reset after a BIOS update. This issue could impact gaming performance and user settings. However, with the new BIOS update, ASUS has addressed this problem, ensuring that the GPU memory assignment remains stable even after updating the BIOS.

The Ongoing MicroSD Card Issue

Despite the exciting changes and improvements introduced by BIOS 323, one critical issue remains unaddressed - the MicroSD card reader malfunction. ASUS officially acknowledged this problem before releasing the update, and the company expressed gratitude to the gaming community for their support and feedback on the ROG Ally.

The MicroSD card reader issue was identified to occur under certain thermal stress conditions, leading to malfunctions. To rectify this problem, ASUS had plans to release an update aimed at fine-tuning the default and minimum fan speeds on the device. By doing so, ASUS hoped to enhance the device's reliability while keeping fan noise in check.

However, with the release of BIOS 323, it appears that the MicroSD card issue has not been resolved yet. It remains unclear when ASUS will provide a definitive fix for this problem. In the meantime, users who are experiencing issues with their MicroSD card reader are advised to contact ASUS customer support to initiate a return merchandise authorization (RMA) process. Under the RMA process, ASUS will inspect the device for any issues and perform necessary repairs.


The ASUS ROG Ally is undoubtedly a powerful gaming handheld that has garnered significant attention from gamers worldwide. The recent BIOS update, BIOS 323, brings notable improvements such as 30 W TDP support for third-party chargers and docks, reduced glare in lowlight conditions, optimized performance in Performance mode, and GPU memory assignment stability. These enhancements aim to provide a better gaming experience and address some known issues.

However, despite ASUS's commitment to improving the device, the MicroSD card reader issue remains unresolved at this stage. Users eagerly await a comprehensive solution to this problem, and it is hoped that ASUS will release a subsequent BIOS update that addresses the issue and ensures the ROG Ally's reliability in all scenarios.

For gamers and technology enthusiasts alike, the ASUS ROG Ally continues to be an exciting prospect, and it is essential to keep an eye on future updates from ASUS for further enhancements and fixes. With the company's dedication to delivering exceptional gaming experiences, we can expect ongoing support and improvements for the ROG Ally in the months to come.
