I'm happy

Edit: VCore fluctuates 0.05V, VTT around 0.18V but no stability problems so far. Temperatures around those groups of four caps were 80c+ before, MBM showed board temperature around 90c - I thought it had to be an error before I measured temps with a digital thermometer which unfortunately only goes to 80c. Caps are barely warm now and board temp is down to about 35c after this fix.
2nd edit: Whats the easiest way to flash without floppy? Bootable flashdrive or what? Tips and any links would be appreciated.
