We have checked the PCB Rebuild about 100 times, and redone almost all the points at least once now... They all have good clean solder points and there shouldn't be any problem.
Cause believe me, that is what I thought would be the problem for sure...
Summary of Tests:1.6Chip in 1.4Box - Frags on 1MB Bank, but not on 512MB Bank
1.6Chip in 1.6Box - Frags on all Banks
1.4Chip in 1.4Box - Works on all Banks
1.4Chip in 1.6Box - Frags on all Banks
EDIT: I wish there were more detailed pics and descriptions of where the points are... Just so I could confirm that EVERYTHING is perfect... But I am 99% Sure they are... The Soldering looks hella better than the PCB Soldering Tutorial Pics
try flashing a 1.6 bios to a bank of the 1.4 chip (that bank should then frag on the 1.4) if it frags in the 1.6 then the issue is probably the soldering
for the rebuild, this is the diagram ive used for every 1.6 ive done (ive always used wire, never had luck with the PCBs, lol)
