Mac Pro :: Operate In Triple Channel Mode Based On The Memory Configurations?
Mar 11, 2009
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...

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?

My question relates to memory configuration. If I buy it with the minimum 4 gig, I think that's 2 2 gig modules. Can I buy two third party (OWC or Crucial) 4 gig modules and add them, giving me a total of 12 gig, or would have to get rid of the original 2 2 gig parts? If it's possible to mix the 4 gig pairs with the 2 gigs, will there be any negative performance issues related to that? If I can mix them, do I need to worry about who I buy the 4 gig parts from? Lastly, any positive or negative comments on OWC or Crucial (or other suggestions) for memory in general?

I upgraded my late '09 13" MBP to 4gb, but one of the sticks apparently died. I'm about to replace it with my old 1gb stick so then I'll have 3gb total ram.
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.

So I ordered a 6 core mac pro and am waiting for it to ship, but in the meanwhile I have a question about ram configurations. I already have 4 x 4 gig ecc 10600 ram. I also realize that according to techs, using all 4 slots will put the mac pro from triple channel ram to single channel as opposed to 2x dual channel. Knowing that would I see better performance with 12 gigs in triple channel configuration or 16 gigs in single channel configuration? Money isn't an issue here as I already own all of the ram.

I have just bought a dual 2.8 8 core Mac Pro and am after a little advise on how to get the best from its hard drive performance. The machine is all stock apart from the 8GB of ram I bought with it.
I will us the machine for my business as a commercial photogrpher (stills only) and using the Mac OS only. Games and TV are of no interest to me with this machine as it will only be used with PS CS3, Lightroom, Capture One Pro and the like.
I am looking at adding some hard drives but wanted some pointers as to what to do. The machine is still in its box so nothing is set up, so ideal to change anything at this stage. I understand the stock 320GB HD is pretty rubbish so was wondering do I get somthing else in its place? If I do, is it simply just a case of taking the 320 out and replacing it with something better and then just booting the machine from the supplied setup DVD's to set up the new HD?

I have carried my laptop on a road trip using motel's free wifi access to the internet. Back home the selected network now wants me to enter the WEP password which I don't remember. Is there a way to retrieve the password without resetting it? More than one computer is on the network - the laptop I left behind remembers the password. Is there a way to retrieve the password from this computer?

How to connect my powermac g4 to the internet. I was told that it has the "built-in ethernet" and that all I need to do is config it so it will pick up the wireless signal from the router on the main family computer. But whenever I go to config the network connection, and check the status, it tells me that the built-in Ethernet is not plugged in. Do I not have the built in ethernet? I just want to connect to the internet, but I don't want to spend over $120 to have geeksquad come and do it if I can just do it myself.

I'm currently setting up two 1TB hard drives as mirrored RAID drives.
Seems easy enough to do through Disk Utility, though zeroing out the data takes about 1.5 days for each drive, due to their size I assume.
Will it be easy to migrate these drives to Snow Leopard?
Will it just be a matter of adding them to the RAID list in SL's Disk Utility? Will it recognize them automatically?

I'm kinda curious as to how fast handbrake would operate on a 12 core Mac Pro? (let's say with 16-32GB RAM) Let's say a 24 minute episode at 640x480 2.5mbps off of a DVD, normally takes about 24 minutes on a 13" 2.4 C2D MBP with 8GB RAM. how fast will the 12 core MP process that? if one day I should have $10K to throw around, I want to go buy a top of the line MP just to have one... It costs the same as an International Business class air ticket, but the MP will last several years while the ticket is only good for a 30 hour experience.

I have a Linksys WRT54G wireless router (v. 6), a brand new iMac (Intel, OS 10.5.4), and an older iBook (G3, OS 10.3.9). I can configure the router using the iBook with no problems. Afterwards, the iBook shows an IP Address, Subnet Mask, and Router under the iBook's Network Preferences. The iMac detects the wifi network I set up using the iBook (for example, "mywifi") but cannot obtain an IP address or other configurations. Sometimes the iMac says Airport has a self-assigned IP address but can't get on the Internet, sometimes it says it has no IP address. I have removed all WPA securities/encryptions to simplify the process, but the iMac still can't see the router. I tried to ping the router from the iMac and no packages were received, 100% loss.

I have a 500GB time capsule that I sue to host my iTunes music and library. I pointed iTunes to the TC folder where the music is. Then I did control+click on the iTunes icon and pointed iTunes to the library which is also located at the TC. As long as I don't restart the computer it works fine, I can open and close iTunes and it finds the library ok. But every time I restart the computer I have to tell iTunes where the library is. Is there any way to configure iTunes so it does not "forget" the library's location?

My grandparents broke their 24in Imac's monitor and it needs a replacement, costing around 800+ dollars. I was wondering if it was possible to operate it with a second monitor and have that one be the main computers display. Is it as simple as connecting the second display or do I have to disconnect the internal monitor? I'm not worried of opening up the computer, its not like I can damage the screen edit: The Imac is out of warranty and is a 2007 or 2008 model. 2.4GHZ C2D 4GB Ram. If you need any more info just let me know

I connect with my MacBook Pro via ethernet to the internet. So far, I've never had a problem until a couple of days, I keep on loosing the internet connect. When clicking through diagnostics, ISP, Internet and Server show first organge then turn red. If clicking through the diagnostics, sometimes I am lucky and it shows a message saying "Network configurations have chnaged", when I click ok, I'm online again. But very often nothing helps and I have to re-start the router again.

The hand gestures on the Macbook Air tracpad is awesome. As I am getting familar with the hand gestures on the trackpad, I was wondering if there are ways to control windows. Below are some of the things I like to know if there are hand gestures for it: Minimize current windowMaximize current windowClose current windowIn Safari, close current tabIn Safari, move from one tab to the next
These are what I can think of it right now. It would be so nice if there hand gestures on the trackpad.

This is a problem that's been bugging me now for a while: when I plug in my iPhone or even a measly Usb Flash drive into my Apple Keyboard's USB port, a message appears on my Mac's screen saying: "A USB device can't draw enough power to operate properly. If the device came with a power cord, plug it into an electrical outlet. Otherwise, connect the device to a USB port on your computer." Does anyone know why the Apple Keyboard has a weird indented USB connector?
