Packard Bell LJ65 RAM upgrade

[PJMylle]

I have a LJ65 Easynote from Packard Bell. It has 4GB of DDR3 RAM. I've bought the Corsair cm3x8gsdkit1066. My internal RAM is DDR3 PC3-8500, so is the RAM that I've bought. My chipset is the PM45 wich supports 8GB. When I put 1 (4GB) or 2 (8GB) sticks inside my laptop, it doesn't boot, even not the BIOS.
The timing of both RAM's are CL7.

Any suggestions?
Thanks

The bios of your machine may be limited to 2 gig per channel. You need to check supported memory
for the actual machine on the manufacturers web site.
