i've tried the usual such as
1. clear cmos
2. unplug power supply, hold power button, cmos reset
3. unplug cmos battery
4. a combination of all the above
5. unplug all usb except keyboard
6. try 1.55 voltage, and 1.45 voltage
7. re-update bios
8. load optimized settings and then reboot and then retry other voltages
8. and combinations of all the above.
nothing changes except the dram voltage and nothing works. I mean if i dont mind the 1.5v the board works great, but thats a big if when the memory is supposed to run at 1.35v
