Okay I'll admit I was wrong about a few things (like the die) it is 90mm but just because the boards look identacal doesn't mean they are the same.

the asrock 775dual-vsta and the 4coredual-sata/sata2 looked identical and they had their differences.

Now back to the memory and the board:

I do believe it is the board with memory problems. With bios 0217 i wasn't able to hit anywhere close to 1150mhz. Then when I updated to bios 308, I was able to hit 1164mhz.

Now that I'm on bios 401, I can hit 1181mhz so it is getting closer.

Since the updated bios releases are achieving higher memory clocks for my memory, that prooves that this board does have memory issues with certain kits.
