Got the hyperX kit today, doesn't work either. Safe to say that my MOBO is the problem. Got this response from MSI support> ''Regarding your concern, from the images you sent on the forum, the MB only detects one RAM size when you install two pieces of RAM. Maybe there is some issue with the DIMMB1 and DIMMB2 slot. Please clear CMOS referring yo the manual, reinstall the CPU and RAM, just install one piece of RAM on the DIMM slots to test them individually. Please use BIOS default settings to test and just install one piece of RAM to test. Thanks! ''PS
Be sure to reset the RAM to 2133 Mhz and save the settings before testing each stick in those slots.
For some reason not all motherboards can run RTAM at 3200 in all the slots.
Some can only run at 2933 Mhz in the secondary channel slots (A1/B1).
I have to go in a few minutes but I will check back in later tonight.
