A lot of time passed, but I still experience the same problems.

Today I notices something interesting, If I put my computer to S3 sleep BEFORE logging in (in windows welcome screen), when it wakes up, BCLK is still 155MHZ.
It just when putting it to S3 sleep AFTER logging in causes BCLK to reset back to 133MHZ.

So I would like to check if it is windows configuration or a driver/service that sets it back.

To test the first thing, I would appreciate if someone with Windows 7 64bit and core i5 CPU that doesn't have those issues can send me an export of the registry hive here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Power\PowerSettings

Thanks in advance
