Any led on the motherboard (even better if next to a RAM slot)?
Usually, the best (if you can) is to swap RAM modules.
If the error follows the RAM module; it is a module problem.
If the error stays at the same position, it is the motherboard.

Hi,

Please tell us more about your system. (lspci, dmesg and cat 
/proc/mtrr)

Best regards,
