This may be my "slow" area when it comes to computers, but I need some help.

I have 8 gigs of RAM for my G5 Powermac, and I try to run many patches in Logic such as many instruments using EW/QL and the like, but it keeps telling me that memory is getting low and may cause problems such as artifacts, etc.

But when I use the activity monitor, Logic is only using 1.92 gigs of RAM and there are still 5.11 gigs free RAM on the whole system!

What gives?

How can I make sure that Logic has the full power of my loads of RAM?

Thanks in advance!

You don't allocate memory under OS X the system does it by itself.

In which versions of the OS X and Logic are you precisely?

I'm in 10.4.9

I figured out that OS X does everything automatically... I just wondered if there was a way to get more of the free RAM shunted to Logic.

I'm not sure if this will help.. I've been trying it out on a couple of macs...

"Speed Freak, at a user-specified interval, reprioritizes applications so that the frontmost (or active) application gets more processor time than background applications. By default in Mac OS X, all processes have equal priority. By using Speed Freak, you override this default by increasing the priority of whatever application you are currently using, resulting in faster application performance. Speed Freak accomplishes this through the Unix "renice" command.

Speed Freak does not affect graphics card performance and will show little to no increase in 3D games. Although Speed Freak does not affect network performance, the increased CPU priority it offers should increase performance in internet applications. For example, web pages with complicated HTML should render faster but download speed will not change."

To "renice" an app will only give it more priority regarding to CPU cycles. On memory, we're stuck, the only thing I've seen approaching is only a way to free RAM by meddling with the Unix memory management (iFreemem if I remember the thing). but I'm rather sceptical about using it, as i don't like meddling with core OS jobs, and I've still to see if it does not screw something or if the free memory is actually used by the active apps…

OSX and Logic cannot access all of your RAM currently, this will change when Leopard is released.

Hey, everyone!

Will Leopard work on the most recent Pre-Intel G5 Mac Desktops, or will it only be for Intel Macs?

Thanks!

Hey, Uvee!

You're experiencing what I've been going through for almost a solid year now. gdoubleyou is correct. Currently, Logic doesn't recognize all the power you have in your G5 PowerMac, and so you are unfortunately going to have to endure this lapse until Apple updates Logic. Grrrrr. Just wanted you to know I feel your pain, and here's hoping Apple gets on the stick soon.

It's to do with 32bit appz, apparently! They can only access a maximum of 2GB of RAM, although OSX does do some clever jiggery that might improve that.
Leopard is 'true' 64bit and as long as the app is 64bit it will access more RAM than we can dream of!
I know this as I had a similar problem, reported it to NI, and a tech guy told me of the 2GB limit, which includes active vsti's i.e. stylus or Kontakt. He recommended using Kontakt as a multi-instrument as it would be far more efficient.

Read the article on P26 : 7 Gigs loaded on One Mac - very intersting....

Hope this helps....

Thanks everyone, there's a bunch that's helpful in there.

Funny, when I got the computer and stocked it up with RAM I forgot the whole cap on memory thing. Which kinda pisses me off, because I could have gone for a 30" monitor instead of spending all that money on RAM that I can't really use (the way I wanted to anyway). Funny... the sales guy didn't mention that!

Anyways, I'll check out SpeedFreak for the CPU, but I don't really have any CPU problems. I just keep getting the whole "memory is low" message warning me of possible artefacts and crap.

Oh well... patience for the new OS and a 64 bit version of Logic I guess.

Thanks again all,

Uvee
