I started comparing the bios collection which is on the web with 1.1125v through to 1.2375 and you end up with at least 7 screens of varying quantities of changes when checking 4 of them.

Top window is 1.1625 compared to 1.1875.
Middle window is 1.1875 compared to 1.2125.
Bottom window is 1.2125 compared to 1.2375.

Added how to change maximum fan speed limit when bios has temperature target enabled to post 1.

I'm wondering if you can run AtomDis for me on a 290X bios? I have sent you PM with one attached.

Do you guys know if the Gigabyte Windforce 290X uses a reference design, or can I not flash BIOS from other 290X on it??

I tried with one 2 weeks ago and it wouldn't show anything on screen until I reflashed the original

The table you've posted does and doesn't help, reason why is each bios can be different in length and location of each table.

So either you use / edit bios that you have a table for or you need to use a table gained by using atomdis for your particular bios to edit.

Tables I created for bios I've been viewing.

This... this is awesome. I feel like the reader is one step away from being able to edit the fields?
