    I couldn't find the right model number at the crucial.com compatibility tool, so I'm hoping someone can help me figure out how to max out my sister-in-law's old MacBook.

    I believe it's from 2008, but I'm not sure if it's the early or late model listed in Mactracker.

    Here's the info:


    Hardware Overview:

    L2 Cache: 3 MB
    Memory: 1 GB
    Bus Speed: 800 MHz
    Boot ROM Version: MB41.00C1.B00
    SMC Version (system): 1.31f1
    Serial Number (system): [redacted ... is the serial number needed to ID it? If so, I'll add]
    Hardware UUID: F8DB820C-D9D4-5049-8D08-E7C85522F9F6

    Serial Number: 0x1791C410

    BANK 1/DIMM1:

    Size: 512 MB
    Type: DDR2 SDRAM
    Speed: 667 MHz
    Status: OK
    Manufacturer: 0x7F7F7F0B00000000
    Part Number: 0x4E543531325436345548384230464E2D3343

    Any advice is appreciated.

    It's the early 2008 White MacBook.

    Max RAM is 4GB comprised of two 2GB modules.

    EveryMac has your full system details.

    Macbook4,1

    Looks like you can go up 6Gs of ram. 2G + 4G modules.

    Good luck.

    Thanks for the help.

    A far-from-comprehensive search prices the 4-gig upgrade at about $60 and the 6-gig at $125. In your opinion, would the 2 extra gig be worth the extra $65? (And since we're dealing with unbalanced 4+2, it'll have a performance penalty, right?)

    The principal use for the laptop is just web browsing, Word and a few old games, but we're not working with video or even Photoshop on this machine.

    4GB should be fine, but if you can get a good deal, max it out.

    If you have 2x1GB chips in there now, and you buy a 4GB chip, you'll end up with 5GB total.
