    Hello, I'm having a bit of a problem in regards to a laptop RAM module that I bought online. I'm trying to add memory to a Dell Precision M4600 laptop, from 4gb to 8gb. The new (used) 4gb RAM was from a mac. The spec on the RAMs are the same with the ones currently installed on the laptop.

    After I installed the new RAMs, the laptop wont boot up.
    Removed the current 4gb ram and installed the new 4gb ram, and the laptop boots up.
    It wont boot when all 4 modules (current and new) are installed together.

    The current 4gb ram on the laptop is two module of HYNIX, the sticker on it says 2GB 1Rx8 PC3 - 10600s-9-10-B1 HMT325S6BFR8C-H9 NO AA 1138A

    The new 4gb ram I want to add is two module of HYNIX, the sticker on it says 2GB 1Rx8 PC3 - 10600s-9-10-B1 HMT325S6BFR8C-H9 NO AA 1143.

    The difference only are the last few numbers. 1138A and 1143. Does the problem lie within these numbers. Please advise. Thank you very much.

    Hi there - memory modules are occasionally advertised as "Mac specific"; the modules you're trying to install may have some properties that are incompatible with the Dell system. The specs are you list look the same but something else might be different (like voltage).

    A sure way to tell is to try the memory you bought in a different make/model notebook entirely. Could you borrow a friend's notebook?

    Sounds like it's either a non working RAM module or one of those rare cases where two memory modules just refuse to work together. It is rare, but it does happen from time to time. I've seen a motherboard that would outright refuse multiple sets of Corsair RAM, put some Kingston in there and everything worked.

    At worse, you could buy a new set of 2x4 GB that is known to work in the M4600.

    Hello,

    The Dell Precision M4600 has 4 SODIMM slots in it... however, if you do not have a specific level of processor, you may only use 2 of the 4 slots.

    From the original issue posted, it shows that you have 2 modules installed, and are trying to install 2 additional.

    Without your system specs, you can't get a good enough answer, but you may also want to check out the following page regarding memory modules in M4600 machines:

    Supported CPU & Memory configurations on the Dell Precision M4600 and M6600 | Dell US

    Sorry if you already have the proper processor to run 4 sticks of SODIMM, and if this doesn't help.
