I think we need to get it far colder or get the cherry sample of the year chip. Some test I can bench 4.9 while others struggle at 4.8 and 4.750, but my voltage is pretty low for the most part. And SS temp is holding like a -35 to -40 under load, while cpu temps hit about 50C most of the time. So I might have to bring out my pot soon.
Side note:
This corsair vengence 2666 memory was quite the surprise though. it can run at 1580 mhz or so.
