F3-12800CL7D-4GBECO error in memtest once a day

[espac]

Hello, I bought three months ago my computer with the memories F3-12800CL7D-4GBECO. configure everything as indicated by the manufacturers and not get it to work well . Format the PC and install Windows 7. All goes well until I turn off the computer and the next day to restart the computer the windows got blue screensaing"dumping phisical memory" . I have changed my motherboard and memory and send to RMA and it arrived last week. but the problem is still there.The problem only happens when the computer has more than five hours turned off. early in the day when I pass the memtest I get errors, if I turn off and restart the computer errors stop appearing and the memory pass the memtest without errors. My team is P7P55D asus, intel i5 750, radeon 5850, F3-12800CL7D-4GBECO.I dont know what happens the problem only appears once in the day, the first time I boot the pc. this is my configuration os BIOS.

tHE PROBLEM IS STILL THERE, now Im uploading the video to youtube and you can see whats happens. I repeat that the RAM was sended to RMA and i left 13 days whitout the pc. How I can be sure that the second replacment will work properly. Can you check if I had all BIOS settings good?

Post up pictures of the BIOS and we can see if anything is set incorrectly. Otherwise, send them back to us and request to have them tested before shipped.

Thank you
