    Hey everyone,

    I recently upgraded from an older dell laptop to a x220 which I really love. I recently was offered the following memory from a friend of mine for an amazing price.

    G.SKILL 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model F3-1600C11D-16GSQ - Newegg.ca

    The price? $60.00

    Now currently I have 4 gig's in my x220 but I do a bit of vitalization work/GNS3 simulation so the more memory the better.
    The current memory in my system is:

    Item Slot #1
    Ram Type DDR3
    Maximum Clock Speed (MHz) 667 (JEDEC)
    Maximum Transfer Speed (MHz) DDR3-1333
    Maximum Bandwidth (MB/s) PC3-10600
    Memory Capacity (MB) 4096
    Jedec Manufacture Name Micron Technology
    SPD Revision 1.0
    Registered No
    ECC No
    DIMM Slot # 1
    Manufactured Week 13 of Year 2011
    Module Part # 16JSF51264HZ-1G4D1
    Module Revision 0x4431
    Module Serial # 0xFD6056D1
    Module Manufacturing Location 15
    # of Row Addressing Bits 15
    # of Column Addressing Bits 10
    # of Banks 8
    # of Ranks 2
    Device Width in Bits 8
    Bus Width in Bits 64
    Module Voltage 1.5V
    CAS Latencies Supported 5 6 7 8 9 10
    Timings @ Max Frequency (JEDEC) 9-9-9-24



    Now the memory from G.Skill is CAS latency 11, 1.5V.
    From what I recall, it being DDR3 1600mhz, it will downclock to 1333mhz due to my chipset correct?


    Would I be safe with this memory as long as it works fine and memtest86 passes it?

    Yes, it should work fine.
