I have just replaced the motherboard with a new one of the same model and booted up. IDU reports:
VR 70c 'over threshold'
I wasn't trusting one set of DDR3 (some Patriot DDR3) that I had previously so I also exhanged it for some Kingston 1.5v (
This begs the question of what might I be doing wrong? Is it possible my CPU is faulty in some way?
For the record I have determined that the three DQ57TM boards have something wrong with them and have returned them all.
I brought my personal system in to work and swapped my i5-750 into the DQ57TM and it acted just as the i7-870's did with VR overheating warnings. I also put the i7-870 into my system (Foxconn P55MX) and it ran perfect with good temps, around 38c at idle for the CPU.
