    Recently I have been having some issues with a MAC G5 we have and it has been crashing daily. From looking at the crash log I think it has something to do with memory but would like a second opinion.

    Code:
    Unresolved kernel trap(cpu 1): 0x300 - Data access DAR=0x00000000548F9010 PC=0x00000000000D9258
    
    Latest crash info for cpu 1:

    it often is memory. you can try pulling and re-seating all the DIMMs, if that doesn't work, pull half the DIMMs and run it that way. if you still have problems, replace the installed with the half you pulled and try again. basically, process of elimination. if no RAM change makes a difference, it's probably something deeper.

    you should also be able to run Apple Hardware Test by holding the D key during startup.

    you can do a RAM test there.

    if you end up with a bad stick or two, I'd say buy a whole new set of RAM. 1.5GB ain't exactly a lot. that machine should take up to 16GB. get yourself 8 matching sticks of 1 or 2GB, PC2-4200 (DDR2-533) 184pin DIMMs of of eBay.

    when messing with RAM make sure to install correctly.

    looks like you are also still running the original hard drive in that. it takes SATA drives so a new drive or even an SSD will also be a performance boost (even st SATA I speeds).
