CPU Error

I keep getting a CPU overload error in Pro-Tools when I bounce. My session is 1 stereo track with no plugins. A stereo master with Maxim and dither on it. 24/48k. Low latency is off. When I bounce, I set the conversion quality to low. The HW Buffer size is 1024 samples, 90% CPU usage and 2 processor for the RTAS processor. My Computer info is Below. Protools is the only program running. What the F***?? Ideas??

Yea, if you write audio on system HD you suppose to be screwed.
Read manuals, man. And, make sure you get an external HD with
7200 rpm, 2 FireWire slots, and fanless.

I'm afraid to do that. I don't know why. I remember the first time I put it on and I had to verify everything and I don't want to go through that again.

This happened to me; it turns out that the RAM the company installed was mismatched. You might need to take it to a qualified Mac repair shop, expecially if it's under warrenty.

Mismatched RAM causing a CPU error? Can you elaborate?

If you run the hardware test disk it will detect and report any specific hardware problem. Do that First then you will know.

There is no need to erase apps of your HD OSX apps do not create conflicts with one another.

Trash your PTLE preferences and repair permissions.

I also suspect BAD or failing RAM.

Are you on a Mac?

I recognize these problems and they occur whenever I try something in ProTools on my MacBook. When recording I cannot get a decent latency without these overloads. HW buffer and CPU usage limit, 2 processors all of that doesn't seem to matter much.

Asusming you are on a Mac, Did you try the simple tweaks?
1. Turn off software update
2. Turn off energy saver
3. Disable spotlight indexing
4. Disable spotlight shortcuts
5. Disable dashboard shortcuts

Is this any different than Apple/about this mac/more info? Also, I got 2 CDs with the MacBook. Which one is the test disk?

This is very strange. You should be able to do this surfing the web and waching a video on your machine.

Try to make another session and import session data from your current session and see if its the same.

Yes it actually exercises certain hardware functions.

Depends on your specific machine what disk it's on.

On the install disk that came with my Mini the fist disk has labeling that says to depress the "D" key while booting.

I wimped out and called mac support, they helped me to "trash the prefs". I'm about to start work on a new song tonight so i'll know if PT is still acting up.

SWEET MERCYFUL F@%K!!!!!

It's still doing it. Lets reiterate shall we. I have one track in pro-tools with no plug-ins, when I play it back an error comes through saying to increase the hardware buffer even though the hardware buffer is set to its highest level. session is 24/44k. To remedy I've trashed the prefs, re-installed pro-tools and updates, passed tech-tool deluxe, repaired disk permissions on my HD. WTF, WTF??? I am so over-frustrated with this problem. Help me out what haven't I done. My whole setup is completely useless now (it sucks now because I have a ton of free time for recording now).

I lost my mac setup disks but new ones should arrive at the end of the week. I guess theres a setup utility that checks the RAM.

All my gear worked fantastic for a long time. WTF?

I don't know about the OP but I tried that. It doesn't seem to matter. It also seems to get worse over time.

Someone already asked you - do you write audio on extrernal drive ?
Or on your iMac internal HD ?

internal HD. Its all fucked today, h/w buffer is underflowing instead of overflowing, the clocks between the mbox and protools are out sync even though they are set to the same setting. I guess i'm not meant to have a nice recording setup.

internal HD.

If it is the system drive no wonder you get CPU errors. I don't want
to generalize, but all people I know to use ProTools use an external FireWire drives as "write" volumes.
So, how many internal HDs do you have in your iMac ? Not the
partitions, the physically separate HDs ?

I had so much progress last night. I was using reason, safari, itunes, a ton of plug-ins, automation and all the goodies. It was a perfect session. Today not 10 hours later, I'm getting all those HW buffer issues. I have to wait till after xmas to get a ext drive.

So my personal life has been turned upside down then shaken in the last 3 months that I had to backburner most of my life (which includes this problem). Now back to normal, I did an uninstall then re-install of protools (with updates). Still i'm flustered. I get the "increase h/w buffer size" about a minute into playback of a session. The session i'm using was one I made before all these issues using the exact same hardware. People in posts above are saying "trashing preferences and reparing permissions will remedy 99% of software glitches. " I don't understand how to do that.
