It's hard to get page outs if all you are doing is posting on MacRumors! Seriously, it's only because you aren't pushing your machine. I had all 4 processors running at least 90% the other day and I have close to 3,000 page outs, and that's with 6GB of ram.5 Gig here. Haven't had a single page out yet.
that is some intense stuff you must be doing.Yea I happened to do a restart when I last posted here the other day and after 1.5 days I'm at 347147/6521 currently with 1.58GB of 10GB free. Still far better off that I was with 4GB![]()
Inactive RAM is basically RAM that has been used before and is being left with it's current data in it in the hope that it will be used again (eg caches). If an application requests RAM for use and there is no free RAM then the inactive RAM will be used.on a side note: why doesnt 'inactive ram' become free ram??
you are exremely lucky. and rich!!!Took delivery of 64Gb of Kingstone memory today for my desktop machines.

Once installed I`ll have eight macpros (sixtyfour cores) running at 16Gb each on my desk.
I got a big desk.![]()
I hope you have a very, very productive job. And a big discount on all that RAM.Took delivery of 64Gb of Kingstone memory today for my desktop machines.

may i ask what it is you do?Im almost as productive as the discount was large....I hope.
I use computers like a person spins plates on sticks...expensive plates.![]()
Question for emeldahay: I was thinking about this: 8 machines, with 64 GB of RAM total, is only 8 GB per machine. Is that right?Took delivery of 64Gb of Kingstone memory today for my desktop machines.

Thank you for the clarification. Amazing setup you have.... It makes my Mac Pro look like a toy.I already had memory spread out over the machines. This 64gb takes them all to 16gb each.
Means I got a lot of the half gig chips left spare...
I`ll ty to get pics of the set up - its too messy just now![]()
They are connected to 30 inch apple monitors - the mp I use the most has 2 monitors attached to it and the others share 4 with gefen monitor switches. I tried VNCing which is too slow - remote desktop is better but I prefer monitor switches.
I`ll be reducing the number of monitors once I get larger capacity monitor switch. Just now I just slide my chair up and down the length of my desk. Its not too bad.
As I've mentioned previously in this thread inactive RAM should be counted as free when you're working out how much RAM you have. Inactive RAM is just caches, the includes the disk cache, if you read a large file from disk (eg just to copy it from one place to another) you will soon have no free RAM left but a large chunk of inactive.Just purchased 2 2gb chips to bring my total to 7gb. To see the system eat all but 100mb kinda pissed me off. Considering i only had Flash/Photoshop CS3, FCP, Safari, Entourage, iChat and GoLive open. Thats my norm, nothing heavy in PS either, a small jpeg i was making into a thumbnail. The majority was Inactive though.
He's right folks. Don't go out and buy more RAM if your free RAM is empty... take a look at your inactive RAM... that will give you a clue as to whether or not to get more RAM. Your system will only go slow if it's crunching a bunch of page-outs... so until it's paging out like crazy, don't go and run out to get more RAM. Be happy with what you've got.As I've mentioned previously in this thread inactive RAM should be counted as free when you're working out how much RAM you have. Inactive RAM is just caches, the includes the disk cache, if you read a large file from disk (eg just to copy it from one place to another) you will soon have no free RAM left but a large chunk of inactive.
After your machine has been on a while the ideal situation is to have almost no free RAM and a large chunk of inactive.
cheers - I think I might have read your thread ???- yours is certainly no toy.Thank you for the clarification. Amazing setup you have.... It makes my Mac Pro look like a toy.
It doesn't matter if you're doing something intense... over time, your RAM is going to fill up and that's what it's designed to do. Do not worry, inactive RAM is a good thing... it's just like free RAM that hasn't been overwritten yet. It accumulates over time.Well I was surprised mostly because at the time I wasn't doing anything to justify all the memory being cached.
So until i open a large PS file, or i'm working heavy in AE or FCP... i still sit and wonder whats going on.
Well, I swapped the RAM and what do you know, my MP is much 'snappier'. Apps seem to open faster. Logic opens in about 3 seconds now even though it has to load over a hundred plug ins, previously it took about 10 seconds. Thanks MM for the tip. The threads on page ins/outs, inactive vs free ram have all been most helpful. I realise that to really get the best from my MP I'll have to get another 2Gb to take me to 5Gb.Should be, but don't ask me to explain it. I only know that this chart shows you how to maximize performance with the sticks you have. Looks like the upper rear is the first part of RAM addressed by the system so you always want that to contain your largest two sticks. Lower rear next then upper front and finally lower front. But not always. Sometimes the third pair goes in the lower front instead of the upper front.

Same here, I started with the 1GB from the factory, but added 2 x 1GB sticks of Crucial before I ever fired her up. Added another 2GB about 6 months latter. Can't remember if the second set was Crucial or OWC. After 2 days 22 hours of up time I have 161000 page ins and 4367 page outs. I generally keep Parallels open most of the time and find that the jump from 3GB to 5GB helped keep things sane. Really improved performance with LRI have 5GB. I upgrade from 3GB which I upgraded from 2x512MB (1GB Factory RAM).
