I usually start with something I know will boot. For the W3520 I think I would usually boot around 245 BCLK.
I think I need to start from scratch like Gappo said. It will take the most time, but I think in the end I'll get the most.
I think I had a semi bad seat on the pot too, I think I'll spend some good time lapping it more tomorrow, and then I need to get more TIM because I used the last of my ceramique in one application and had to try and reuse it when I took everything apart to add more insulation.
