Hello suzuki.
No, the CPU has not been tested on air, yet. Just wanted to do something "just for fun" yesterday and that's how it came out.?
VID of the CPU is: 1.2625 volts
Max vcore with which the CPU still booted into Windows is 1.865v
But luckily you can adjust the voltage of the CPU via the Rex in Windows ?
will test today/tomorrow what is possible with increased voltage
