Thanks. IOH was 1.35v BIOS set and ICH was at default voltage. The UD5 is a good board from what I've seen. I have kept a copy of 1504 on one BIOS chip so I can flash it over the other BIOS chip (I use BIOS2 for testing new ones and keep a low numbered BIOS on BIOS1 to avoid that ridiculous 'can't downgrade' issue).
