So thanks for this video very helpful

If anyone is willing to help I am unsure how to calculate how to extend the length since I added 4 values.  It is stated in the video that they started with 2C 01 so it needed to change to 30 01.  My value for my nitro + rx 480 Elpida 4gb is 5a 00 with a length of 5E.  Unsure how to calculate what to extend it to.

any help is greatly appreciated!


------------------EDIT--------------------
So I was finally able to get this to work.  I realized that the length is in the first 2 hex char not 4.  So once I found an online hex to decimal converter I was able to calculate my length.  I continued on to the rest of the video without issues.  I did not save a lot but total on my 5 card rig I was able to shave 30 - 40 watts off but the biggest savings is I was able to get each card down about 8 - 10 degrees in temp.  It was interesting with the voltage offset added and opening the rom up in srbpolaris, I was able to select a range of offsets in VDDC which I have not noticed on any other cards I have.

 

I set mine to -100, I could probably get more but ill sit on it to see stability.
