I had 4 running at 12800 & decided to buy 4 more for 24 gig.
the second set are running at 10600 why?
Shouldn't they both show 12800?

I have a GA-X58A-UD3R motherboard Here are results from Mentest & CPUZ

Where it's showing as 1600 in the one set and 1333 (PC3-10700) in the second set is coming from a setting in the SPD programmed into the sticks to provide a set of default settings for the sticks that matches a JEDEC standard...the set showing PC3 12800H in the MAX Bandwidth spot are carrying the newer default programming...it's nothing to worry about
