Everything seems to be working fine for me. I tried out 1.4a bios yesterday and i kept getting problems, it wouldn't boot properly. So i had to go back to 1.4 and everything was all good
System resume from sleep works fine for me also. I recommend updating to bios v1.4. It was the first thing i did when i first got this extreme4

Here is an update of my overclock and the voltages I'm running. Hope this will help other people when it comes to overclocking for them.
