My system specs are as follows: i5-2400/RX480 8GB/Windows 10 x64. The new drivers sometimes crash with symptoms similar to an unstable overclock (the screen freezes, goes black, then the monitor says "no signal" and I have to restart) even when there isn't actually an overclock. The usual troubleshooting measures like clean installing the driver don't work. The 16.11.5 drivers work fine even with an overclock and undervolt. Also, the problem seems to manifest itself more often after the latest Windows 10 update.
