Seems like there are a lot of minute differences on the P5K Premiums depending on batch and factory.

The one on Newegg site has PCB made in Taiwan and MEC inductor beside the DIMM slots.

The one on the first page has all round RIO inductors.

I have two Premiums, one has RIO inductors all round but CPU area is 'brandless R68', and the second premium has a MEC inductor for the DIMMs but 'brandless R68' for the CPU area. Even the DIMM slot manufacturers are different for both boards! I'm getting a board with all 4 slots having the same kind of clips, while the other has differing pairs (like the one on the front page)!


I haven't come across any other brand that has so many differing components for the same revision number.

But I like the Premium, clocking my previously stubborn Crucial 10th Anniversary much better than my old board.
