Low the max boost? Nope, not unless 1506 isn't stable for "MOST". Is 1506 not stable for you?
0 length, you're right
Hey we just discovered something
The posted BIOS is for a DP BIOS.. Some people run a DD BIOS. Gigabyte has a dual BIOS that does NOT have a switch and is determined by the video outputs you decide to use. Any chance you can teach us how to HxD this bad boy or possibly edit a DD BIOS for us also? I am sure someone can post a STOCK DD BIOS for us.
Sure! The trick is to find the start of the voltage entry array. This is usually after a large field of 0, though that is too common throughout the file. There is a preamble of sorts, but it may be variable for all I know. This part of the preamble -> 50 1D 04 08 03 03 F0 <- should be constant for all.
Probably the most easiest way to find the start of the voltage array, is to duplicate the bios, change the value of the first slider (the max voltage one), and use HxD's comparison feature (ctrl+K) to find the difference. This should land you on the start of the 3rd entry in the array. The second entry is some random stuff, sometimes empty, sometimes not, and the first is the unknown 600-1275 entry. The blocks are 34 bytes (or 22 in hexadecimal, HxD displays selection length in hexadecimal), so the start of the voltage array should be 2*22 = 44 = 68 bytes before the first difference.
Or, if you do not care about the start of the array, and just want to change the two values for throttle and binning, you go from the difference 34 (22 in hex) bytes forward, which is the binning entry, and another 34 (22 in hex) bytes forward, is the throttling slider.
Once you are confident you have found the starts of the entries (hint: usually after an FF byte, but not always though), you can replace the next 8 bytes (2 integers) with this ->E2 8C 13 00 E2 8C 13 00<- This is the number 1281250, twice in succession. You just select the 8 bytes and copy-paste.
After that, the sliders will appear in MBT.
Here is the DD one with slider values as close to the original as possible
