I'm having some performance issues with my Mac Pro 2006. There are pops and clicks which won't go away with whatever settings I use in the Configure Hardware Driver. Would I benefit from installing more RAM? I currently have 9 GB and maximum RAM is 16 GB. Since it's seven years old I guess the rest of the hardware will soon start protesting if it's not mainly a RAM issue. Are there any PCI processor cards which would do the trick? Other suggestions? Or would I be better off just keeping it for simpler tasks and permanently move all my DP projects to my MacBook Pro?

Does anyone know which one is the best OS X and DP combination for the Mac Pro 2006?

What kind of interfaces are you using? I have the same MacPro with 7GB of RAM and I'm using PCIe based MOTU interfaces and am doing pretty well, although I do more rock songs and not orchestral mockups with lots of VIs etc.

I don't have any additional hardware installed in the computer except for a hard drive. Echo AudioFire2 is the only additional (external) hardware. It's working fine with my MacBook Pro. Maybe there's something putting strain to the processors. At this startup I noticed everything in the Finder came up faster than usual. Can't say I've done anything different that would affect speed, but I'm going to take another shot at the issue. I only had one mono audio track into which I recorded some rhythm guitar. I disabled effects too and still couldn't get a clean sound.

Edit: could should be couldn't

I'm currently not having the issue. The only thing I come to think of is that I was running Finale at the same time as DP. Then I quit Finale - no change, made a restart - no change. Since then I've moved the authorization for Finale from Mac Pro to MB Pro. Could that make a difference?

Shooting in the dark, e-snobben: of course you do use OnyX (free app) for your maintenance tasks?

And BTW, DiskWarrior and iDefrag to keep your HDs healthy?

If not, I suggest you do give a try.

They made huge difference on my own setup.

I use TechTool Pro now and then, as well as CleanMyMac2. I also use the Mac OS X disk tool. Haven't used Onyx for some years since I've found it to be "for the OS X experts". You have to be sure of what you're doing so that bad things won't happen.

For sure, I'm no OSX expert! Never screwed anything undoable with OnyX, though.

BTW, I highly recommend updating a HD clone before any major maintenance, OS or app update.
SuperDuper does this in minutes.
IMHO, your best *total wreck* insurance!

Ok, thanks
I'm beginning to like Time Machine, automatic backup is off though. I too have a HD clone, but nowadays it's not that much a clone as before due to Time Machine. I use it for temporary small backups only, when I don't have the time to plug in the other one.

A clone may save your job in case of HD going south while on a deadline.

BTW, never had a mother board gone south, but a HD did, just a few days before a big gig. Since, SuperDuper has been my friend.

It seems to be related to the MAS. When I've been working for a while the issue can reappear from nowhere. Sometimes it's enough to clear inserts. Sometimes I've got rid of the pops by going into the Configure Hardware Driver and just click in the buffer size menu, not changing anything. It makes the MAS turn off and on again.

I used to hear similar pops and clicks when I was using the first version of 'The Grand' by Steinberg. It was a piano plug-in that was very demanding even for a souped up G4 of that time. In my experience these pops and clicks are always related to the audio buffer. I was able to eliminate them by increasing the buffer size when mixing a song.

Chances are your main computer is adequate enough but your audio/MIDI interface connection needs to be updated. If you are forced to use an older slower USB connection you are pretty much out of luck. I remember hearing these clicks and pops even when I used a dedicated machine just for 'The Grand'. Selecting a lower sample rate (16/44.1) can fix the issue on older machines as well.

Since you have TTP, you have the only tool you need to properly diagnose a RAM or HD issue. Like Onyx, DiskWarrior and iDefrag, TTP can't really fix anything but it is an excellent diagnostic tool.

You want a picture of the SMART graph and frequent testing of the RAM. With certain video cards, you need TTP 6.04 or earlier or 7.02 or later due to a firmware problem with those cards that Apple will never fix. 6.05 to 7.01 will not show the graph you need if it detects one of those video cards. RAM problems are often heat related and may be elusive.

If you find a problem with the drive, use Apple's Disk Utility to repair. Then replace the drive with a new one ASAP. Properly repaired drives go bad again anywhere from a few minutes later to a few weeks.

I don't think you have a bad drive or RAM but you could. The driver for your interface could be the problem.

So could your buffer settings. You want low settings when you record - even if it means that you can't monitor more than a few tracks. Increase your settings for playback and mixing and see if this doesn't fix the issue.

I've already tried different buffer settings but that made no difference.

I'm short of time at the moment. I'll be back.

e-snobben... the only time I've every had click/pops issues was when I wasn't using uniform RAM in my Macs.

You say you have 9GB of RAM. This immediately strikes me as a red flag because you obviously don't have matched pairs.

You should be using an even assortment of matched DIMMS (from the same manufacturer) in each slot. For example... 4 4GB DIMMS = 16GB RAM, or 2 8GB DIMMS = 16GB RAM. You're asking for trouble if you start mixing up your RAM like having 2 GB in some slots and 4 or 8 in the others.

Matched pairs = happy Mac.

Apple would disagree with that assessment. RAM must be installed in matched pairs but this v.1.1 machine came from Apple with 2 half-g sticks in the first slot pair.

It is possible to install sub-standard RAM in this beastie and ordinary PC RAM did have a problem with crapping out when too hot - as this tech note from EveryMac.com attests:

1.0 GB of RAM installed as two 512 MB modules. 6 slots free. RAM must be installed in pairs, and for "best acoustic performance" contain an "Apple-approved heat sink".

OWC noted this too and made a point of stating that, though their heat sinks looked different, the performance met or exceeded the factory installed RAM.

One of the problems was "acoustic performance".
