So I was playing around with my 3770K on my Z68X-UD4 last night for the first time and it seems as though these chips don't overclock on z68. The maximum multi you can set is 39...kind of dissapointing. Perhaps I will be able to bump up the bclk a few ticks to get a bit further.
I guess my only options would be a future bios update that fixes this or I will have to pick up a z77 board when a used one comes available in a few months time. ~4.0Ghz will be fine for games, but it would be nice to be able to push the chip a bit further.
