out of memory errors? suddenly?

hey guys;) me again..
ok so i never have got this error untill just the last day or two... my machine shows 1.12gb of ram .. not sure where the .12 is coming frm but yea.. i have over 1gb of ram.. i dont know how or why this just started to happen to me quite frequently when opening apps. digital performer 3 says it to me everytime i open it now and it never used to..

is it possible some of my ram just went bad? im gonna try to swap chips out to see if the problem goes away.. but just wanted to ask anyone here on the garden if theyve ever had ram just suddenly go bad for no reason...... or develop some type of incompatibility with each other? im just trying to figure this out because like i said the problem just appeared.. and was not there before..

ive only had this machine a few months and i bought it second hand for running some oldschool music programs.. its a g4 450mhz sawtooth.. i upgraded the video to a radeon 8500. its aldo got a delta 410 pci sound card ..

ive jsut checked the chips and its quite a mishmash of unmatching chips which is always never a good thing hehehe
1x512mb
1x256mb
1x128mb
1x128mb
that was the configuration..
im taking out the 128mbs and firing up with just hte 512+ 256 to test....

I've cataloged over 8000 Mac errors. As a developer, this HUGE number was impossible to write a decent error message handler for so some of the time, I "cheated" and posted an "Out of Memory" error regardless of the actual error I got.

It is possible that the guys who wrote DP did the same. Look for other symptoms.

hmmm,,,whats the biggest culprit you can think of then gary??

its such a bitch because i love os9 but its always a whiney crashy bitch
i wish i could get osx that looks just like OS9... i gotta be honest its the ui that i like

when it locks up just from me clicking something while its doing something else.. i get sad because i know its a matter of time before i will have to turn my back on it forever if it doesnt want to behave for me!

>whats the biggest culprit?

With over 8000 errors to choose from that's a hard one. BUT given the flakey nature of the Sound Manager in 9.2.2 (and its REALLY flakey), I'd start there.

So is the memory labelled as 512MB, 256MB and 2x 128MB ?
Or is that what it is reported in Apple System Profiler ?

Are you saying that you get 1.12Gb reported in "About This Mac" while ASP only reports 512, 256 and two 128's ? If there is no onboard memory - I don't think there was - that would indicate to me that one of the 128Mb sticks is a 256Mb stick gone bad, ie. one side is cooked. This may be the cause of your error - the top of the stack / heap is near the bad memory, there's a request for more and it's denied because the memory is bad.

Or is it just that you have allocated too little memory to the app in OS9 ? Big displays and high colour bit-depths can consume vast amounts of RAM.

What was the name of the excellent OS7 memory mapping app ? It ran in OS9 and in classic. It was quite funny to see it run with 1.5GB available to OS9 when it was designed for Macs with 4MB or less.
I still have this on my MDD, which I can fire up and find the name of if no-one else can remember.

One other thing occurs to me. Your memory total (1.12 GB) vs. the amount of installed physical memory (1 GB) says to me that you have Virtual Memory turned on. Digital Performer does NOT like that.

Make sure Virtual Memory is turned OFF.

OS 9.x supposedly doesn't allow VM to be turned on if there is more than 1GB RAM installed (a 1GB+ limitation). I'm thinking (as this is a recent purchase) the RAM sold with this box is not what it seems, its either dodgy, mismatching or fubar larger chips as bertyboy suggests as a possibility.

Better to take the RAM out and do a search on the them to see whats supposed to be in there. If he's got one in there that's supposedly 512 MB and is reading 256 MB, or one or more that's supposedly 256 MB and is only reading as 128 MB, then its time to do some RAM swapping/chucking.

And when swapping sh*t, don't forget the cuda switch.
