GTX 465 to Quadro - Soft Strap calculations

[The_Moves]

Has anyone had experience doing this? I've followed the posts that I could find on different forums, but have had no luck. I believe i'm on the correct track though.

 

Would anyone be willing to work with me on this?

 

Here are my notes, which I coped and pasted from another forum, though i'm not sure my post is actually visible without logging in, or even posted correctly there:

root@XUbuntu:~/Downloads$   od -tx -Ax 465STK.ROM  | grep -E '^0000(5|6)0'

000060 7ff1ffff 80020000 95a538e1 e9445ee9

 

Above I used the ROM I pulled off my card, though this ROM from TechPowerUp is identical as far as I can tell:

Here are the MASKS for my GTX 465 and Quadro 4000:

Card     DevID   AND mask 0   OR mask 0    AND mask 1   OR mask 1
EVGA265  06C4    0x6FFC03FF   0x00005000   0x7FF1FFFF   0x80020000
Quadro4K 06DD    0x7FFC3FFF   0x00004000   0x7FF1FFFF   0x80020000

Here is my conversion based on the Device ID:

GTX465        06C4  0000 0110 1100 0100
Quadro 4000  06DD   0000 0110 1101 1101
Change              xxxx xxxx xxx1 1xx1
                    xxxx xxxx xxx4 3210

ID Bit:   4                  32 10
Strap: -xxA xxxx xxxx xxxx xxAx xAxx xxxx xxxx
Old Strap:
AND-0: 6F        FC        03        FF
       0110 1111 1111 1100 0000 0011 1111 1111
OR-0:  00        00        50        00
       0000 0000 0000 0000 0101 0000 0000 0000
New Strap:
AND-0: 7F        FC        27        FF
       0111 1111 1111 1100 0010 0111 1111 1111
OR-0:  10        00        74        00
       0001 0000 0000 0000 0111 0100 0000 0000

With the above work, I've come away with these two potential combinations, but both error out:

Calculated AND 0 and OR 0:
nvflash --straps 0x7FFC27FF 0x10007400 0x7FF1FFFF 0x80020000
 
With original AND 0: 
nvflash --straps 0x6FFC03FF 0x10007400 0x7FF1FFFF 0x80020000

This is the errors I receive "Error: Strap values out of range":
