I'm still confused about XMP, after much research today.

I bought a Dual Channel Kit, PNY XLR8 8gb (2x4Gb)
DDR3 PC3-1700 @2133MHz

After checking CPU-Z & BIOS readings (ASROCK 970 Extreme 3 R2.0)
It is showing 1 stick has an XMP table setting and 1 stick does not.

I swapped sticks out individually and ran 1 at a time to see if it XMP was only a secondary installed stick table, but no. It looks like only 1 of the 2 sticks has an XMP table.

When both sticks are installed, CPU-Z & BIOS show running in Dual Channel fine.

So question my question is why is there only one XMP stick in a dual channel kit?

Reason for looking into this is I'm trying to track down screen freezing/computer freeze on a new build.... Memtest86+ Came back good on each individual memory stick test, but Very/Immediately Bad results on the initial test with both sticks in.

Thanks in advance :)

Solution
Check out the part number on the first screen shot, looks like someone slipped a PNY 1333 stick in there which is why no XMP profile - XMP only applies to sticks specced at 1600 or better
