Ram in THREE's? & 2 vs. 3 channels

Why would ram be sold in packaged sets of THREES?
Also how do you get to triple channel ram use and to how much advantage?
If it requires leaving one bank open, and stock Mac Pros come with 6 X 1GB,
you gotta throw somne away to upgrade, ugh

The Mac Pro uses DDR3. "3" as in triple-channel.
Memory is configured on each Riser separately. If you do it "wrong" a utility will pop up and tell you even.
I would read some review aticles on DDR3 and triple channel.
And while this won't answer any of your pressing needs (maybe Barefeats and OWC has a chart of their own), some background helps.

Oh, and read the booklet, it tells you how to follow the numbers to fill DIMM slots (1.....8) in sets of 2, 3, 4, 6 or 8 DIMMs.

[Other 865 Series] MSI 865PE Neo2-V and Dual Channel Mode Question

Hello, I have a quick question regarding dual channel mode with my current motherboard. I have an MSI 865PE Neo2-V and am wondering if it is possible to enable dual channel mode while having three RAM modules inserted in the motherboard.
For example, I currently have one 512MB PC3200 module in my computer. If I purchase another 512MB module and run them in dual channel mode, will it be possible to buy a 1GB module or another size module, and still have all three slots run in dual channel mode? Or is dual channel only operational on this motherboard if only two of the three slots are occupied?
Thanks.

Dual channel requires an even number of sticks.

About Mac Pro RAM and one "Nehalem" Processor 2.8 vs 3.2

Hi,
Unfortunately I don't have so much money to spend but I find Apple products very high quality and in same time very expensive, specially for my country (Russia), according to statistic, it’s less then 1% of people that using Mac Pro in here, my country really poor :/
I never use Mac before, but I think that time is come and I would like to buy one on my birthday soon (22 November). I really tired of my crazy PC with Vista, it’s always bugs lags, and so on, it’s poor machine. I can buy new PC with i7, nice performances or buy Mac, but I think, Mac will be more quality and stable.
I'm web designer and programmer and using my PC with Adobe programs, normally Photoshop, Illustrator, Dreamweaver, very rare with After Effect (1 day per month). Sometimes I’m playing games like Dragon Age or CS:Source, Starcraft2. But I got PS3, but unfortunately it’s connected to our main home TV, and I can’t play PS3 because all day this TV watching my family :/ lol
I’m not sure if there are any way to connect PS3 to TV and computer screen at the same time… but it’s another question.
Now about Mac I'm wondering of buying cheapest Mac Pro 2010:
# One 2.8GHz Quad-Core Intel Xeon “Nehalem”
# 3GB (3x1GB)
# 1TB 7200-rpm Serial ATA 3Gb/s hard drive
# ATI Radeon HD 5770 1GB
# One 18x SuperDrive
But at the same time, I wondering about how long time I will be able to use this Mac, and enjoy it before it will come too old. Because I just can’t spend and buy Mac every 2-3 years.
I’m looking forward to use it for 4-5 years I think or so. I know it’s very hard question and I’m not really sure if it’s right to discuss it, but I’m saying just what I think.
And maybe because of this, it’s better to order processor with 3.2Ghz, and a bit more RAM (8GB (4x2GB))? What you think?
And what will be the different between this 2 processors and more RAM? Because it will be +800 USD or so, and it’s very expensive for me (pay addition 800 Dollars), I just want to ask you if it will costs this money. Unfortunately I can’t spend more money on Mac to buy 6-core Westmare and more RAM But I think cheapest Mac, for my tasks already very powerful and awesome, what you think?
And if you’ll advice me, not to pay addition 400 USD for +0.4Ghz, and the different is very little, then what you think about addition Ram for stock MAC?

Thank you hatter.
I'm appreciate for your help and answer, and this amazing links! They are very helpful.
I find some interesting information. And most interesting is SSD thing. But unfortunately it's very expensive for me

And I’m not really sure, if they offer high quality components, and I can’t check it.
I just don’t want to repeat same experience like with my previous computer – I bought top computer for very high price with top components, but everything was bugging, it’s terrible, I’m working with this computer 3 years now (it’s cored 2 duo with radeon x1900 and vista :S video card - without supporting DX10-11, 2 Hdd 500Gb RAID 0, - maximum lags – I cant’ even make a diagnostics… crazy). And I’m so sad about this computer, and I don’t want to repeat same experience. That’s why I wonder about Mac Pro or any other quolity PC, but price is too high, or if I buy just normal Mac Pro:
• One 2.8GHz Quad-Core Intel Xeon “Nehalem”
• 3GB (3x1GB)
• 1TB 7200-rpm Serial ATA 3Gb/s hard drive
• ATI Radeon HD 5770 1GB
• One 18x SuperDrive
• Apple Magic Mouse
• Apple Keyboard with Numeric Keypad (English) & User's Guide
For 2499 USD, I still need to add more RAM, and It will costs 2874 USD with 8 Gb, but without changing Processor and/or HDD for SSD to speed up computer like **** and enjoy it every minute. I maximum can spend 3000-3200 USD for new computer. And all I want, to enjoy it’s stability and speed. To load photoshop in less then 5 seconds, working with AE a bit, 3dmax a bit, play a bit. Maybe I want to much :/

Falsely accused of installing 3rd party RAM into my macbook pro while just a month away from my warranty expiring

Hey, this is my first "post" here on Apple discussions.
Since i bought my Macbook pro in October 2011, my macbook has been given for servicing many times. We've always used the Authorised Service centre here in Singapore (QCD Technologies), and I can swear I have never taken my laptop to a third party. However, when I gave my laptop in for servicing yesterday because it wasn't booting up and instead beeped 3 times every time I tried to switch it on (suggesting faulty RAM), they told me that they can't work on the laptop until we talk to Apple because they claim that the RAM installed is not original (suggesting that we used a 3rd party for my macbook's repair). Needless to say we were extremely appalled because we have never consulted a 3rd party, and this makes it extremely clear to us that either QCD or Apple slipped up in their servicing/production without accounting for changing the RAM or are simply lying. If they don't have a log for it, then we know they made a mistake, however the problem is they can easily use this as an excuse to evade costs on their part.
Has anyone else experienced this? What should I do from here on? I need my laptop for college quite urgently and It's very convenient that Apple is doing this just 1 month before my warranty after extending it, expires finally.

Have you taken the computer to the same repair place every time it was repaired? If so, suggest to them that they must have installed third party RAM. And, another fact to consider: Apple does not manufacture RAM - it always uses third party RAM. They do change suppliers, so different machines may have different brands of RAM. And, as mentioned: installing RAM does not void your warranty - you may want to point that out to the repair place as well. Although, to be fair, a senior Applecare rep once told me to reinstall the original RAM before sending in the machine for repair so no one could possibly blame the problems on third party RAM.
You can easily install RAM yourself; use one/both of the links provided by leroydouglas to purchase the correct RAM as three beeps at startup usually mean there is a problem with the RAM.

VIEW won't display channels with same names

Hello,
We have recently installed DIAdem 2010 and are beginning to find channel name problems that we didn't have before with 9.1.
Traditionally we have always set the name-oriented channel references to 'only channel name' and we have never had any problems when displaying multiple traces in VIEW. Now, we find that when we display more than one trace in VIEW with channel names that are repeated we get problems with the axis system display dialogue box. This dialogue box tells me that the X and Y channel names AND NUMBERS are the same for all three traces when in fact the data displayed is different. If I try and change one of the channels it immediately reverts back to the first channel with that name.
I have attached a screen dump to help explain. The image shows a VIEW window with three speed time histories from three separate data files that have been loaded together. The three X channels will all be named 'time' but will be channel numbers 1, 4 and 7. The Y channnels are all 'speed km\h' and are numbered 2, 5 and 8. However, the dialogue box shows that all three traces are made from channels 1 and 2 despite the three traces appearing different. If I change one of the 'time' channels from number 1 to, say, number 4, then it reverts back to number 1 as soon as I move the focus to somewhere else in the box. Version 9.1 never had this problem.
If I swith the name-oriented channel references to '[group index]/channel name' then the problem goes away - even thought the data displayed in the graph is the same!
I'm not entirely clear on the reasons for settling on 'name only' references - probably historical - but I am even less clear on the effect of switching to '[group index]/channel name', particularly with the many autosequences that we use.
Is this a bug that can be fixed?
Regards, Si.

Simon,
The DataFinder is a database that DIAdem installs that integrates directly into the NAVIGATOR, so that you can easily query data files/groups/channels or compile properties from multiple files into correlated curves on a graph, etc. You might be interested in the ability to look inside your data files in the NAVIGATOR to see the group/channel structure and their properties. This is particularly interesting if you wan to load selected groups/channels from one or more files.

ACK_ channel for handling ALEAUD back to ECC system

Hi,
I have created a channel called ACK_Receiver_XI_TO_ECC for sending ALEAUD for all IDOC's that are received from ECC to XI. I also have another receiver IDOC channel for all IDOCs that are sent from XI to ECC. I read in one of the pdf's that when there are multiple receiver IDOC communcation channels, the one starting with Ack_ is chosen to send the ALEAUD. But in my case, in Development and QA system it is correctly picking the Ack_.. channel but in production it is picking the other receiver IDOC communication channel. Any ideas why and how this can be rectified? I have the "Restore original parties.." option checked on the Ack_.. one and not on the other so the selection of the other in production is giving me the "Unable to convert sender service to ALE logical system" error.
Thanks

Hi Ram,
>I also have another receiver IDOC channel for all IDOCs that are sent from XI to ECC. I read in one of the pdf's that when there are multiple receiver IDOC communcation channels, the one starting with Ack_ is chosen to send the ALEAUD
I dont think so, the channel will be determined by the Receiver Agreement. If you have more than one what are valid for a message, that is take which is less generic. For example, if you have 2 Receiver Determinations and you type in the first at Receiver Interface a joker (*) and in the second for Receiver Interface a certain value the second Receiver Determination will determine the channel. This is a general rule for IB objects and allows to create generic rules but having exceptions.
Please compare the Receiver Determinations in the different transport layers.
"Unable to convert sender service to ALE logical system" means, that your sending system has no value for logical system. Control that at Business Component, Adapter Specific Identifier. If the sender is Business System, correct that at SLD and reimport the system.

Udo

Dual channel question

Hi,
Just want to know.....i have 2x512(matched pair) DDR 400 , how can i be sure that im working in dual channel ?
And if i add more 512 in the third ram slot ill still work in dual channel ?
Thx

Quote
to use dual channel you MUST have the same amout of memory in slot 3 as you have in slot 1 and 2.
Well if so then why is it that before I got my second lot of 512Mb of ram I had 512 in slot 1 and 256 in slot 3 and it was running in dual mode.
Then later I put 512 in 1,256 in 2,and 512 in 3 and it was still dual mode.
I have even had 256 in 1,512 in 2 and 3.
Regardless of where I put them it still runs in dual channel mode.

Basic questions about AirPort and channels

I have a VERY limited knowledge about networks. Please keep answers simple.
My setup is very basic. My computer is connected to the internet via AirPort through my wireless gateway (router).
When I pull down the AirPort menu from the toolbar it lists 3 network names plus Other. My network name is checked. Why are 2 others listed on my computer? They aren't listed in my AirPort Network System Preferences under Preferred Networks so I can't delete them.
I downloaded iStumbler to try to get more information. It lists all 3 names plus one more that comes on and off. My signal is over 100% and all the others are around 50%.
Also, three (including mine) are using channel 6 and one is using channel 1. Should I change my channel? Everyone always mentions 1, 6, and 11. Could I use 4 or 5? Are some channels stronger than others?
Thanks.

"...Why are 2 others listed on my computer?"
You have neighbors with wireless networks and you are getting a signal from them.
"They aren't listed in my AirPort Network System Preferences under Preferred Networks so I can't delete them."
You can't delete them because they are your neighbors signals.
"should I change my channel?"
I would switch to channel 9.

How to play multiple instruments simultaneously on different MIDI channels?

I'm very new (today!) to Mainstage and I have a Yamaha HX-3 organ with three keyboards (Upper - Channel 1, Lower - Channel 2, Pedalboard - Channel 3). I'd like to play all three channels live simultaneously with a different instrument on each one (ie. Piano, Organ and Bass) but I can't figure out how to do this.
I've managed to setup a concert with all three keyboards on different MIDI channels with three different instruments but I can only play one of the keyboards at a time. The other two show MIDI keyboard activity but no sound...HELP!
I also have Native Instruments Komplete 7 if that would help in this regard (I know the Hammond organ sound in Komplete lets me play all three keyboards at the same time).
Thanks,
Don Thompson.

First create 3 keyboards in Layout mode and assign each to its own MIDI channel (I think you may have done this already). Then, create three channel strips, either at the Concert, Set, or Patch level with the three sounds you want to use. Each Channel Strip can be assigned to a different keyboard from your layout. To do this, go to Edit mode, select a Channel Strip, and look at its attributes in the pane below your layout. I don't have MS in front of me but there should be a dropdown list with the keyboards that you have in your layout. Just pick the right one for each strip and you should be good to go.

Kingston KHX3200AK2 added more RAM

I am stumped. I recently added two sticks of KHX RAM. The previous setting were as follows. FSB 201, Dynamic OC Sergeant, perfomance setting Turbo, DRAM Speed at Auto, SPD Auto (2.5, 3, 2, 5), RAM Volts 2.7. With one set RAM sticks, it ran well on dual channel. When I added another set of RAM (same specs), my PC would not fully POST. With those BIOS settings, it will POST with either the old, or the new RAM, but not both. I had to set the DRAM speed at 400, and manually set the SPD settings to 2.5, 3, 2, 6. I turned off Dynamic OC, and performance to Slow. It does POST, and runs well. with both sets of RAM, and in dual channel. Here is the head scratcher. The DRAM speed sets itself at 333Mhz. In essence, running the CPU to RAM at 5:4. I did try increasing Dynamic to Private, and performance to Fast. The DRAM speed stays at 333.
This is odd to me. Any suggestions.
Thanks,
MIke

Thanks for the answer. I wasn't sure if it were the RAM or the board, so now I know. I purchased the RAM at a very good price, I do see a faster response time, and it runs in dual channel. That said, it works well for my use. Thanks Again, Mike

After Effects not recognising all RAM

I have just installed After Effects on a new PC with 6GB of RAM, however on the splash screen that appears when loading up AE it says x% of 4GB RAM being used.
Do I need to do something to make it see 6GB?
Thanks in advance.

> I have read all the posts and advice and still come out confused - I
have 8GB (on OS X) and just leave the multiprocessor options switched
off until someone comes up with a clear and concise walkthrough for
idiots like me !
from the post that I linked to:
"Let's take an example of a computer with eight processor cores and 8GB of RAM:
For HD, you want at least 2GB for each process; preferably more. And you almost always want to leave at least 2GB for other applications. That leads to some relatively simple math. For an eight-core system with 8GB of RAM, leaving 2GB for other applications gets you down to 6GB. That's enough RAM for three processes at 2GB each."
Is there something about that that you don't understand? Set Minimum Allocation Per CPU to 2GB. Set RAM To Leave For Other Applications to 2GB. You're done. After Effects will use three processes for rendering.

If I change audio levels in AE CS6 from 0db, it decides to output left channel only.

This is a bug that's been prevalent in every iteration of AE CS6. I'm updated to the most recent version. This is also something I've seen around a lot of forums, but nobody has an answer.
If I change the audio levels on any audio track from the default 0db, the RAM preview only plays back the left channel which completely breaks the way I can properly work.
If I render it out, the audio is fine... it's clearly only on RAM previews. But rendering out things to check audio levels is not a solution.
Any idea why this happens?

Using A Flash Drive To Boost RAM

Hey all, I have several questions here. I do sound recordings with my Mac G4 Quicksilver, and need to do some upgrades to run different software. I currently have 10.3.9 but need to go as advanced as I can??? Please forgive my lack of knowlegde when it comes to computers... I catch on fast, but I really don't know much currently. I'm looking at purchasing a 1.8GHz processor to upgrade from 800, and as far as I know my RAM is maxed out at 1.5GB. My computer also doesn't have a DVD drive.
Question 2: My system as far as I know is maxed out on available RAM, all three slots have a 512MB, totaling 1.5GB or so. On Windows, particularly Vista, you can plug in a 4GB flash drive, and with a few clicks, utilize the 4GB for RAM. I've purchased a 4GB flash drive through Ramjet, with this hope in mind. Is there any way to boost the RAM on my Mac by using this flash drive? Are there any other ways of boosting the RAM?

SoundMind76:
My system as far as I know is maxed out on available RAM, all three slots have a 512MB, totaling 1.5GB or so.
Your RAM is, indeed, maxxed out. That is as much as the QuickSilver will support. However, it will be plenty enough to support Tiger, and even Leopard, if your processor upgrade allows the installation of Leopard. As noted by earlier posters, you cannot use a USB flashdrive as RAM. Here are the technical specifications for Leopard and the minimum system requirements for Tiger.
I'm looking at purchasing a 1.8GHz processor to upgrade from 800, and as far as I know my RAM is maxed out at 1.5GB.
I am not familiar with the processor upgrade to which you refer, but if you can do that it will give you a very powerful computer. The processing speed comes from the processor, and RAM and a minimum of 15 GB available disk capacity (free space) will improve efficiency.

1GB of RAM on Logic...

Is a 2.0 MacBook w/ 1Gb of ram good enough to run logic express 7?

I would say it is. The more RAM you have the more simultaneous audio channels you can have, but 1GB should be adequate for most. I've got 2GB and when I run several channels of audio, plugs/etc., I still have plenty of free memory. YMMV though.

AirPort Extreme Auto Channel Selection

I monitor my wifi environment and noticed that when I turn on my AirPort Extreme it chose a channel (11) that was also being used by multiple near by networks. These networks indicated the highest signal value of all the other nearby networks indicated, a value between 45 and 49. I am not experiencing any concerns and my AirPort seems to perform much better than the Verizon WiFi which I turned off. I left the AirPort on for a few hours and noticed that a couple other networks joined the same channel 11. I cycled my router and the new channel it chose was 6 and no other network nearby was on 6. The popular channels nearby seem to be 1, 6, 11. Would I be better off selecting say channel 8 or 9 or some channel other that the three popular ones and setting channel control to manual??? As I said I have no issues and my Apple TV seems to like the AirPort Extreme because I have not experienced the connection to the Apple store problems that I was having where I had to retry several times plus authorization and loading time has gone down. I shut down my AirPort and Verizon devices at night or when they will not be used for a few hours. By doing so at least the Airport picks a new channel. Thanks for any advice.

Would I be better off selecting say channel 8 or 9 or some channel other that the three popular ones and setting channel control to manual
I don't know who first said that wireless was half science and half voodoo, but they pretty much nailed it.
There really are only 3 wireless channels that do not overlap....1, 6 and 11.....so it is not hard to figure out why they are the most popular. If you choose channel 8 or 9 for example, then it will overlap both 6 and 11, so you actually increase your chances of picking up interference. Same for channel 3 or 4 for example, which will overlap both 1 and 6.
If you have the time to experiment, it won't hurt to try different channels to see if you can find the magic setting. But, since other routers around you are constantly changing as well, what might appear to be a good channel now, might not be a few hours from now.
