I know many say that the sheer volume of 16gb outweighs the speed difference between the two channel settings, but I'm wondering how 32-bit programs (mostly audio applications) will address the RAM best?

Call me crazy but are we all assuming the Nehalem Mac Pros can operate in triple channel mode based on the memory configurations suggested by Apple? I can't find anywhere on Apple's site or in the user manual that spells out the ability to run in triple channel mode. I know the integrated memory controller can operate in dual or triple channel mode. Being dual only would explain the number of memory slots. Can any owners of the new Mac Pros confirm triple channel operation? Or has anyone seen it documented one way or another by Apple? I'd love to be wrong...

Will this turn off dual channel mode?
Computer has 2x512 memory sticks. Can I add one 2gb stick since the CPU sees only 3.3gb total? I realize I'm losing dual channel capabilities.

I have Toast Titanium 10 and toyed with it for awhile but couldn't figure it out.
When I start importing video into iMovie '06 from my DV camcorder, the sound changes to one channel only (I know the audio on the tape is stereo), and stays that way perpetually, even after I quit iMovie, restart, zap the PRAM, and even do an "Archive and Install". I had to do an "Erase and Install" for it to return to two channels. But the second I start importing video in iMovie, it's back to one channel. I checked the Sound control panel and Audio MIDI Setup, and everything looks fine.
View 5 Replies View RelatedWe had a mixup in either our sound board or our camera and recorded some video only in the left channel. I thought I could just duplicate the traci in garage band, then swap the channel on the duplicate track so we could get audio from both sides. I've duplicated the track, but can't seem to figure out how to swap the audio over to the right side.

View 1 Replies View RelatedWhen I plug my MacBook into an external audio source via the headphone-jack using the red and white cables (do not know the technical name), I only receive sound out of one speaker. At first I thought one of my stereo speakers had blown out, but I plugged my computer into another stereo using another cord and it still only plays one speaker. Also, when I plug in any set of headphones I only still receive sound through one speaker (the left one). My computers speakers still work, and when nothing is plugged in it still says under the output type that it's Built-in Output. I also noticed that sometimes (but not every time) when I unplug something from the headphone jack that a red light flashes around two times, but it does not stay lit when there is nothing plugged in.
**Another note: The sound is not in mono in one speaker, it is just like one speaker is turned off.
Is there anything I can do with software to get my headphone jack to play in both ears. The jack plays in one ear. I cant figure how to play it in mono.

I recently purchased a Retina Macbook Pro 15" no more than 3 months ago.Â
Today I just noticed that whenever I connect my headphones I can hear the left channel clearly but the right channel is a lower volume and distorted.Â
at first I thought it was the headphones, but have tried various ones and it doesn't seem to be that.Â
Also, output from the internal speakers sounds fine, same level on both channels and clearÂ

So far this is my set up. M- Audio Fast Track connected to my Heil PR40 via usb. This is what I use for podcasting with GB and all is well on that front. In iMovie however, my VO only records on the left track and not in stereo. It sounds ok for being on one channel but I would like to have it stereo.

View 5 Replies View RelatedI have a white 13" MacBook. I'm totally Mac illiterate. I bought the Mac because I just about to dig my eyes out in frustration dealing with MS Vista. I like the MacBook.....but about a year and a half ago, the right channel of my 3.1 speaker setup cut out. It worked fine for the 1/1.5 years of ownership.
Internal speakers? Work just fine. Headphones? Perfect stereo.
External speakers with subwoofer? Right channel is dead.
I've tried max laptop volume and creeping volume on the actual speaker up. I've tried max external speaker volume and creeping the Mac volume up. I downloaded a ToneTester program. Internal speakers and headphones just fine. 3.1 externals? Right channel dead. I don't have the red-light jack issue. My Sound Output toggles between Headphones and Internal Speakers output perfectly. About 7 months ago while putzing with all the settings, I got it all back out-of-the-blue. Perfect stereo with subwoofer. I had it for about 2 months and then poof - right channel faded again.
I came across some youtube video with dual-language audio; ie. one language on the left channel and another language on the right channel. The Output page under Sound preference does not have the left/right balance control, probably due to the mono speaker in MBA. If I connect to an external speakers, or headphones, then the balance control re-appears. Is there a way to get around this problem, if I still want to use the build in mono-speaker?

I have an electric guitar plugged into the instrument input of an Apogee Duet recording interface.
If I add a "real instrument" track, then I can select the input channel in the "track info" pane in GB. Works fine, I can hear the guitar. But I can't access the various guitar effects and models.
To do that I create an "electric guitar" track instead. However, when I do that, I don't see any option to select the input channel in the track info pane.
And I don't hear any sound. Apple help just says I should "select the input channel in the track info pane" but I don't see it there, like it is for a "real instrument"...
what's going on?

Since I'm experiencing some issues with my current setup (4870+GT120) I'd like to hear if the new cards work on 10.6.5 with at least two displays connected to it, and one of them in portrait mode. Ideally someone with three screens connected to a single card and two of them in portrait (on the DP outputs).
View 2 Replies View RelatedI ran some tests on my 2009 Quad Nehalem to try and determine what was up with the triple Vs dual memory "brouhaha".
I posted the results as a new thread because I think it will be useful information for a lot of quad owners, but it was originally going to be a reply to this thread: http://forums.macrumors.com/showthread.php?t=735845
Here we go. Tesselator suggested 3 tests that could show the differences in speed between triple and dual channel bandwidth.
Quote:
As one idea I would maybe try creating a few very large images (16-bit, blank white, blank black, gradient fill) and then duplicating and deleting that layer repeatedly a few hundred times.
So I did them, 10 times each. I could have gone on, but the results were very very stable after the first 2 attempts.
Set-up: a 40Mpx, 16bit image (8000*5000). First test it was simply filled white; second test: black; and third test a black to white gradient. I added a fourth test, using a real (photo) 12Mpx RAW image from my Nikon D300.
I created (took a while!) an action with 350 repetitions of "duplicate layer" and "delete layer", followed by a red fill to let me know the action was done. The same action was used in all four tests.
The computer was restarted before each of the four tests, which may explain the irregularities on the first 1-2 attempts. Nothing else but PS4 was launched.
The results are interesting:
We can clearly see that the simple white and black fills show a speed difference of around 10%.
We can also clearly see that this difference disappears when a more complex image is used. The use of more complex images represents a much more realistical use of PS.
To make things even more realistic, I also tested RetouchActions's speed test on my own 12Mpx image. I use nearly all of the operations of that action on a daily basis, so it's a lot more representative of the work I do on PS.
Here are the results:
The results are clear: 11% increase in performance using 8GB of ram (Vs 6GB) when working on a 12Mpx image.
Added info: number of page-outs after running the 10 test series (after about 45 minutes of intense PS work):
-17K when using 6GB (1.7K page-out avg).
-10K when using 8GB (1K page-out avg).
For me the results are definitive: unless I plan on working only with full black or full white images (not even black and white!), having 8GB is better, even when working on smallish 12Mpx files. I imagine the differences would have been even greater using bigger file sizes of actual complex images.
What would now be interesting: someone with a 2009MP Octo doing the same tests at 12GB and 16GB.
