Trying to Upgrade Laptop Ram, Won't Boot

Hi All,

I have purchased some new laptop ram for my Asus X55L notebook. It currently has 4 GB and want to double it to 8 GB. After I install the new ram, the pic fails to boot, does not even get to the bios.

Current ram is labeled as SK hynix 4GB 1Rx8 PC3L - 12800S - 11 - 12 - B4 - HMT451S6AFR8A - PB N0 AA 1347C

New ram is Kllisre 8GB DDR3 1600 PC3-12800S-CL100

Thought I would ask the question to anyone who may know more about this subject before I send it back... thanks in advance!

  1. please try to use new ram alone for testing - if you want to be sure, try to use the new one in another device - so we can at least see, if we have incompatibility issue or dead on arrival ;)

    p.s.: normally that ram should do, for "beginners" (no offense intended) it's easier to buy identical ram and consult qualified vendor list for compatibla ram modules

    SK hynix 4GB 1Rx8 PC3L - 12800S - low voltage
    Kllisre 8GB DDR3 1600 PC3-12800S-CL100 - not low voltage

  3. overseen low voltage, shame on me - many thanks rgd!!!

    okay, low voltage and your notebook means, you need to run memory with 1,35V - but the new model just supports 1,5V and will not work with 1,35 V

    ^^suggest to return the new one and select rgd's answer as solution
