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?
Just swapped in the second pair of CPU/HSF in this system, then my other PSU. Still the same. Reading on the internet now about how these HSF units are considered by some to be very inadequate....but even at idle? Really? Thoughts or experiences anyone?
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.
