BIOS 2802 Comments

Just noticed that this new BIOS has just been released. I'll probably try it over the next few days and provide some comments here...

Always good to know what others think.

According top what I've read, DTT is a power saving feature, often enabled on laptops etc for better battery life. You should be able to try it if interested, but I've had no reason to investigate further.

Guys, I just tried to update to 2802 and I've got the "Selected file is not a proper bios" error... is there a way this can be fixed without having access to other PC? Thanks

once you download it,  righ click and extract. then run renamer in adm to change the name of the file that the board read.  copy that to a usb formated in fat32 (up to 32gb) or exfat whent he usb is bigger. 

Enter bios, and update. i can recomend to load default just in case.

I have done this so many times and i have problem CERO

The only drawback is that the settings file saved on the USB stick does not copy to the new BIOS (empty fields).

I seriously hope that Asus can be more descriptive about the improvements done to the new BIOS. Just "more stability" is very vague. Stable in terms of RAM? Overclocking? Voltages? Improvements with new features?

Anyway, just tried updating the BIOS to version 2802. Ended up unable to boot with the Q-Codes showing 98, B4 and A9. Managed to switch back to the previous version. Lucky me.

Hi guys. I just updated to BIOS 2802. Here are my observations.

1. I have not been able to apply the .CMO profile that I had as a backup.
When I try it, it puts blank values and just doesn't boot. (I noticed that the options in BIOS changed, possibly this is the reason why this configuration file no longer matches.) So I had to configure my BIOS by hand.

2. It still does not have enough support and stability to run 128GB in 4 32GB modules at 5600MT/s.
I have 2 DDR5 Kits of 64GB each with XMP profile at 5600MT/s and base speed of 4800MT/s. I have been trying for a year to be able to run 4 RAM modules of 32GB each at different speeds and it has not been possible. I hoped that with this BIOS update it would be possible, but it is not yet the case. Currently, the 128GB only runs at 4200MT/s and I feel that the system is not stable. I'll run a MEMtest to confirm.

3. I am under the impression that this update was solely to add compatibility with the upcoming 14th generation. Nothing more relevant than that.

Greetings.

Hi,

1. CMO compatibility across UEFI builds is never assured. It's often recommended that you build a new one when flashing to a new BIOS revision. The fact that they are sometimes cross compatible is simply a connivence.

2. You're combining memory kits, which is not supported or recommended. If it's not working now it's likely never going to without manual tuning.

3. Yes, the update contains CPU ucode and ME firmware for 14th gen processors.

I am able to run 128GB DDR5 RAM (4 sticks of 32GB) at 5333MHz using BIOS 2703. The intended speed was at 5600MHz. 

Look like I have to give this upgrade a miss unless I am switching to 14th Gen.
