I am building a new system using the Corsair memory above(2x4gb) on a Gigabyte GA-970A-DS3 board with an AMD FX-6 6200. It's currently running with all the AUTO functions enabled in the BIOS which run the memory @ 1333/1.5v. The board spec is rated @ 1.5v for the memory and up 2000 OC for frequency. (If I manually enter the multiplier I can run @ 1600 using AUTO voltage control). When testing either individual sticks or as a pair they fail on test 7 of memtest giving almost unlimited errors for this test. I haven't enough knowledge of memtest errors to know what to do with this result. I haven't loaded the operating system yet so can't update the BIOS or run CPUZ. Could both sticks be faulty, or is there a motherboard / CPU problem? Any suggestions please...
