I have been trying to upgrade my Medion Akoya p7618 Ram from 2 x 2 Gb ram to 2x 4 Gb ram New ram is Crucila 4GB DDR3 L-1866 SODIMM 1.35V CL13, CT51264BF186DJ. The Bios seem to regonize the ram as 8 GB. But thePC boots over and over again. I have this short message. "Your PC ran into a problem and needs to restart. WE´´ll restart for you". If you call a support person, give them this info: Stop code: KERNEL SECURITY CHECK FAILURE No problems when I put the old 2 x 2 GB ram Any suggestions to solve my problem?
