 MacPro 2.4GHz 8 core with 32GB RAM

if that's the machine, that uses DDR 3. TRUST ME, 32 is not divisible by three. you'll be getting 8 GB of RAM that's more or less a waste. Ask around here if you don't believe me.

I dont understand ! why divisible by 3 ?????

8 x 4 GB or  4 x 8 GB = 32 GB

If you dont have enough memory to have all your orchestra loaded in memory your system will keep swapping, reducing the number of VI !

To monitor this you must run the utility "activity monitor" select system memory and watch if swap used if greater than zéro 

it's triple channel. http://en.wikipedia.org/wiki/Multi-channel_memory_architecture#Triple-channel_architecture

I have installed RAM in a mac pro 8-core with DDR 3. The OS tells you how to install it and it's by threes.

Apple is not being 100% forthright putting 8, 16, or 32 in there. "The architecture can only be used when all three, or a multiple of three, memory modules are identical in capacity and speed, and are placed in three-channel slots. When two memory modules are installed, the architecture will operate in dual-channel mode.^[9]"

to the OP: actually with Apple sticking 6 1 gig sticks in there, and you want it filled up, you're taking that 6 gigs out to begin with. it's your money. I wasted enough myself on this issue!

As I stated earlier I have a PPC G5 which will not run Logic 9, because logic 9 can only run on an Intel Mac.  So I cannot use the G5 for sequencing if I want to use Logic 9

Also from your latest post civilization 3 a MacPro can only have 6, 12, 24 and 48 GB's of RAM and work to its full capacity.  Is this correct?

You can go to 64GB but you must use special rams and remove all installed RAM

To have an idea go on crucial.com, select Apple and your computer and it will give you what you can put in your computer

example for my 12 core

24GB kit (8GBx3)
DDR3 PC3-10600 • CL=9 • Dual Ranked • Registered • ECC • DDR3-1333 • 1.5V • 1024Meg x 72 • • Part #: CT1469655

(0 Ratings)

Memory Type: DDR3 PC3-10600, DDR3 (ECC)
Maximum Memory: 64GB
Slots: 8
Each memory slot can hold DDR3 PC3-10600 with a maximum of 12288MB per slot.*
*Not to exceed manufacturer supported memory.

Decided to go for MacPro 12 core 2.66GHz with 500GB SSD and 2 x 1TB Hard Drives.

Do I need to get a mac mini to use MIRPro effectively or can I run everthing off one computer?

Hi Mirabile,

 VE/VI and MIR will run on the fastest computer Logic will run on the MAC mini

You can put your system on a 128 GB ssd too

If I was you I will buy 2 x 250 ssd and put them in Raid 0 to put your VSL lib, you can always add another ssd of 256 gb to have 750 gb

In general, it is not very good to use RAID drives for samples. Putting the libraries on the drives separately will allow you to utilize the parallel access of your drives without the need for block synchronization.

pease give us figures ? give us a template so we can try it on our various configurations !

I have been using Raid 0 for my samples since year, all the bench I have done so far are showing that they load much faster on a raid 0, more you have drive in the raid 0 faster it is.

The only thing with raid 0 is if you have a problem with one drive everithyng is lost, so you must have a backup of your lib on a HD

If you RAID the drives, all heads need to synchronize for data load. Thus, your access time per sample will be the minimum of one disk's access time, while having the samples on different disks will allow all drives to seek to different samples independently. It gets a bit messy with library distribution over the drives however, since it is hard to evenly spread out a library across several drives.

give us a template that we can test !

How about you test yourself?

One interesting test would be to use IOMeter and set it to 100% random access with 16k block reads. This simulates sample streaming and loading rather well. Test it on a single drive and then the RAID respectively. Then multiply the IOPS result with the number of drives for the non-raided test, and you'll get a decent estimation of (theoretical maximum) performance.

You forgot to divide by the age of my mother and multiply by the age or the captain !   LOL LOL LOL

Iometer does not exist for Mac

To do a real test with VSL will be to make a template and load it on different configuration. The problem is there is no error message when you ask to load something that you do no own ! You just get an empty instrument, and as this instrument is empty it will load very fast !!!!

Can you add an error message when you cannot find an instruments ?

You still have not answered my question with respect to running everything off a 12 core Macpro.  Will I be able to run a large orchestral score on just a 12 core machine with 48GB's of RAM?

Thanks for your help.

Regards

Mirabile

You have partial answer, on my 12 core I can run :

Logic with a very heavy score and 97 vi + 3 input + 2 x K4 + 1 x omnisphere

I have propose to test your a sample of your song when I return from holiday after the 25 th
