Please make sure that you have the latest BIOS for your motherboard and then load optimized defaults and set the Memory Voltage to 2.1 volts and then set the timings to 4-4-4-12 (CAS-tRCD-tRP-tRAS) and then test the modules ONE AT A TIME in the slot closest to the CPU with http://www.memtest.org! Please allow memtest to run 2-3 passes on each module. If you still get errors, we will be happy to replace them! However, if you get errors with multiple modules that would suggest some other problem and I would test them in another system or MB to be sure.
