Memory Type??? (Parity vs. non)

    Ok...upgrading my IBM box, maximum memory is only 384 MB :( (3X 128 MB).

    Question: For audio apps, should I use parity or non-parity memory. I understand that error-checking can slow down the memory, but does it help with audio apps?

    If I put in an extra 512 megs of ram(making my PC 1024 megs) would I notice a difference? Ram is so cheap now I figured I'd pick up another 512 megs...but if I'm better of spending the money on twinkies, I will!

    Ya know...I've never really thought about that issue with software apps...I do know that you probably should stay with what the motherboard reccomends..it really depends if you have SIMM or DIMM sockets on the board..usually the manual for the motherbaord will let you know what you should get...judging by the fact that you can only have 384MB RAM I would say that you might have SIMM..older stayle memory sticks..
    As for you Munkee...going with 512MB RAM is definately worth it..helps deal with plugins and processing..the less it has to put to disk the better..Twinkies have an unlimited shelflife so why not stock up on those as well...great sugar level booster for those late night mixes too..

    Actually, my memory chips are 168-pin DIMMs (SDRAM) running at 100 MHz instead of 133 MHz (bummer :( ). The computer was a year old last May, so it is considered a "grandpa" by now.

    I checked on Crucial.com and they state that it will accept either parity or non-parity. (Non-parity has error-checking, and usually 9 chips on board instead of 8). Error-checking is useful for servers according to Crucial, but is a bit slower.

    Unfortunately, on this mobo, IBM only supports 128 MB chips, and it only has 3 slots...it really bites the big green weenie...

    I am probably going to go with a SCSI drive, and switch it over to a new box in a few months if this one gives me problems...it is just hard to pass up a "free" box when it is just sitting here.

    ohh google.com, I love ya'!!!
    solution

    Anyway-
    from
    http://www.pcguide.com/ref/ram/packParity-c.html

    " Non-parity is "regular" memory, including one bit of storage for each bit of data. Parity memory includes one
    extra bit of storage for every eight bits of data, used to store information about the
    data that the system can later use for error detection or correction"

    "Parity memory will usually work in a non-parity system; the extra parity bits are
    ignored. However, non-parity memory will not work in a parity system (unless parity
    checking is turned off in the BIOS setup program, and some older systems don't even allow
    that). If you use non-parity memory in a parity system, a parity error will be generated
    as soon as the system boots up."

    so there ya go!

    party vs non-party! :D
    er... I mean parIty

    It kinda depends if you like to allow random errors in your data. Modern systems use error checking.

    OK..so now we a have a pretty good definition of what party vs. non-party memory is...(Dang...did I say "party" too??? It is contagious! I *meant* "parity"! :) )

    Now back to the original question...what is recommended for digital audio? llornkcor2's comments (where the *hell* did you get that name anyways??? Sheesh!) were something like

    "It kinda depends if you like to allow random errors in your data. Modern systems use error checking."

    I assume that was an endorsement for using ECC chips (error-checking). :)

    Any others?

    spell his name backwards....you'll get his name after that!!! lol!!

    I dont think it really matters what the software sees..it really depends on what your system can handle and how well it performs and how the OS reacts etc etc etc..use what the motherboard reccomends

    Most machines are fast enough where I don't think that the difference between error checking and non is going to make much of a difference. Maybe if you are using a 386 or something. Get what the motherboard can handle.
    I've had better luck in general with parity memory. Just don't mix parity and non parity memory in the same system.

    Opus I heard you say you use "Nexthardwareshop.com" How are they? I want to buy some more RAM and I don't want to get screwed. They say it's Micron...do you think it is? Is there anything I should watch out for?
