As requested in Hardware Questions & Answers (refer to link below), I tested the P67A-C45 with the latest BETA BIOS available pairing with 2600K. Due to the fact that the review done by coolice was actually done during pre-NDA time, the Max Multi available was x38. But now it's fixed. Refer to the Screenshot below. Cheers.
