[homeboy]

Hello,

I've got laptop K72Jr and I would to upgrade my RAM.
Could someone tell me if these caracteristics of new RAM is compatible for my laptop. Thanks

This is caracteristics of my previous RAM:

DIMM:               1
    SMBus address       0x50

    Module format       SO-DIMM
    Manufacturer (ID)   ASint Technology (7F7F7F7F7F7FC100)
    Size            2048 MBytes
    Max bandwidth       PC3-10700 (667 MHz)
    Part number     SSZ3128M8-EDJ1D   
    Serial number       00000177
    Manufacturing date  Week 46/Year 10
    Number of banks     8
    Nominal Voltage     1.50 Volts
    EPP         no
    XMP         no
    AMP         yes

DIMM:               2

You need to make sure your computer is 64bit, otherwise... there's no reason to upgrade past 4GB (without kernel mods, which, hell, you wouldn't be asking for our help if you knew how to create your own custom kernel)
But judging from the specs you've given us, I think it should be compatible being that they are DDR3, PC3-10700 (667 MHz)
AMP is something I wouldn't worry about though that's not going to make your ram incompatible.

Best to search up what kind of motherboard or PC you have on Google to see what type of RAM it takes. They seem compatible from the info that you've posted though, but don't quote me on it.

Hi , you can consult the laptop oem spec as this notes pertinent memory specs (although regarding internal speed , not the only supported options)
