This time with the new mainboard, it offset my swap by ~ 8mb ? Basically I have been making a: 7168mb and b: (swap) 512mb. Before I am pretty sure it was letting me land swap starting at 7169 but this time it padded that to 7177 I think.
So while I did change a few variables at once (I know I know not the best troubleshooting…) - I really do believe the old mainboard / CPU (although this was happy in the IPX) / FPU / Cache are ill. I’m going to keep this old machine around and if/when I ever have enough SS2 flavored parts to troubleshoot some more I will so that I can salvage as much as possible from it.
