Extra heatsinks on the Top & bottom of the chip, with a large fan & fan controller, temp sensor for the controller is the black wire going into the heatsink, temp is set at 40 Deg C.
Potentiometer to adjust the core voltage, and digital display showing the core voltage.
The unit is being run from a small 5V PSU. At the current 250Mhz it is taking 8.7W at the wall.
Last year I had this setup up to 400Mhz, however for some reason at the moment I can't get it to reliably run over 300MHz. I think disabling wireless has improved things and significantly reduced restarts, RichBC 1 at 200MHz has been running for 8 Hours now without restarting. However I find the higher I go above 200MHz the more problems there are including number of restarts and not starting at all unless a full reboot is done?
I feel there are still some things I do not understand, but have some ideas so will next Week start exploring them.
RichBC 1 will be down for a few hours as I am going away for a few days and will take it with me. RichBC 2 I will leave at home running at 250MHz and we will see what happens?

rich-bc, are those small heatsinks recycled or custom order? thanks
