G5587 and RAM upgrade issue

Hello,

Any G5587 user got RAM upgrade issue?

I tried two RAM module but the machine failed to detect it.

First one came from Crucial: http://www.crucial.com/usa/en/bls8g4s240fsd

Another one came from Kingston: https://www.kingston.com/dataSheets/HX426S15IB2_16.pdf

Machine failed to detect RAM module and failed to boot.

Did anyone upgrade RAM with G5587, which module is compatible with G5587?
