3.8 was the highest i could get my 1055t to on the 790 chipset.
What volts are you at for 3.7 and how hot is it getting during a run of blend test in prime95?
Sorry it took so long to update again Bin...
At stock voltages (VCore 1.41 volts), air cooled:
Idle avg ~35-37 degrees
Prime 95 blend avg ~50 degrees, peak at 55 degrees
