    I just dropped 4 gigs of OWC RAM into my Santa Rosa 2.4 Core 2 Duo 17" MBP with NVIDIA 256 Vram and a 7200 RPM 160 gig Drive (with 100 gigs free). Tiger 10.4.11


    I ran disk utility and fixed permissions (3 times). Trashed the cashe and cookies. I restarted it, too (twice)

    I know that RAM doesn't always make a computer faster (i.e. unless you are running several applications at once). But you would think it would help opening GarageBand files and sampling loops while playing back a 5 track song.

    I even got a rainbow when I looked up applications in the "About this Mac"

    Your mbp probably just doesn't like you. Try giving it a blanket at night..;) But, really, I would benlangdon's advice and reinsert the RAM.

    I was completely AR when I put it in. Didn't touch a thing. Used a non-magnetized screw driver, touched the inside to rid of static, etc. System shows the RAM as functioning.

    If some guy at OWC touched the connections, is there anything I can do to clean the pins on the RAM?

    If that doesn't work then try running memory test program to see if one of the stick is defective.

    Cleaning the pins won't help - if there's a short, you'd get crashes, not just slower performance. Make sure you installed it right. Go to the Apple Menu->About this mac and make sure it has 4 gigs there. If it does, then it's just in your head

    If all the above doesnt work, try putting back the old ram in and see how it behaves...if it does as you say performs faster, Id return that 3rd party ram you bought and get a replacement, preferably another brand.

    Does this mean that with 4GB of memory on a MBP we should never expect to see the rainbow?

    No the point was, that with 2gb OP's system didnt have rainbows where with with 4gb it does.

    That's odd.

    I just upgraded from 2gb to 4gb of OWC branded RAM on my MBP. Absolutely no problems here. I do notice an improvement in performance when running multiple applications.

    I would suggest running memtest, someone else posted the link above. Its 2 dollars to download. If memtest shows there's something wrong with your RAM, get on the phone and give OWC a shout. They have a lifetime guarantee on their product, so I'm sure you could make an exchange.

    Tonight I'll do the mem test.

    RAM replacement question?

    I don't mean to steal this thread, but I was wondering if replacing the RAM voided the warranty? I thought I had read that somewhere. Thanks.

    It doesn't void your warranty, there even is a guide on apple website on how to do it your self.

    Replacing the HDD however will void your warranty.

    Make sure that the RAM is seated correctly. Sometimes you haven't pushed the sticks in far enough.

    I've been told be many people here who have called up Apple reps (plural) and told them that it doesn't. If you break anything in the process you're screwed, but just replacing the HDD does not void the warranty.

    In other news, look like I won't be ordering RAM from OWC!

    how much did you pay for them by the way

    4 gigs from OWC (which is spoken of quite highly on MacRumors) came to $103.00 with 2 day shipping. RAM is really low right now. I'm running a memtest as we speak.

    I guess I'm not feeling the whole "Screaming" thing.

    i installed 4gb's of owc a few weeks ago in my 2.4 mbp and where it really made a noticeable difference was awaking from sleep and running programs after the initial (1st) run. ie: cached info. i do get way less spinning beach balls now too.

    Worst comes to worst, I would do an erase and reinstall of everything. That is if nobody else has any other suggestions. Otherwise if you don't have the time just put back in the 2 GBs for now and when you have the time you can do it.

    I notice it says you have 3019 MB. Looks like one of your modules has some nonworking chips.

    i agree, i had problems with a express card for an esata connection and after 3 reformats and instals of the driver it worked then crapped out, but when i reformatted for the 4th time (so everything was back to normal) it seemed as if everything was working cleaner (i think i had some things running in the background) than before. o ya, do not try and reformat it 3 times as it will change nothing.
