I have 4 sticks of CMX8GX3M2A1333C9. 2 were purchased 1/17/11 and were paired with a I5 2500K that overclocked nicely. I then upgraded to a I7 3770K and added the 2 new sticks that I purchased 3/3/15. The upgraded CPU did not overclock very well and, even though the 3770K has a reputation as a pretty good overclocker, I just wrote it off as one of those CPUs that doesn't overclock very well (perhaps a bad lot or something).
Today I was looking at CPU-Z and discovered that the SPD information of my memory, despite the exact same part numbers, do not match up. The max bandwidth for the two separately purchased sets of ram sticks are different. 2 sticks show SPD Ext. as XMP 1.2 and 2 sticks show no SPD information at all.
Note the slot numbers:

Is it possible that 2 of the sticks I purchased did not have XMP support?
Or...is this just how my motherboard handles the memory?
TIA,
