Is more than 8 GB RAM useful for Logic ?

Hello
I'm considering the purchase of a MBP Retina, on which it's impossible to add RAM. I have been working with a MBP 17" with 4 GB and had no reason to add more since I hadn't switched to 64bit yet. I thought that the 64bit version would give me access to as much RAM as I wanted, but the guy in the shop, a certfied Logic Pro specialist, tells me that it's not true, that the 64bit version has access to 8 GB RAM max, and thus that instead of ordering a MBP with 16 GB which would come in 3 weeks I might as well get the 8 GB version which is available now. . Who's right ? And are there other reasons for me to get more than 8 GB ?
Thanks !

Hi
Not 'exactly' "as much RAM as I wanted", but enough so that you don't need to worry about it.

Wrong. Logic in 64bit can access as much RAM as you can fit in any Mac right now... and more.
Your main issue is that it is impossible to upgrade the RAM on a Retina MBP after you have purchased it, so if you decide that 8G will be enough, rather than 16G, you will have to live with that for the life of the machine.
8G is good, 16G is better (or likely will be in the future.

More than 4GB of RAM in iMac 8,1 under Snow Leopard

Greetings,
I have an iMac 8.1, running under Snow Leopard in 64bits mode (i.e. kernel is in 64 bits). I am wondering if I can install - and use - more than 4GB of RAM now that my iMac is booting in 64bits mode?
Thank you for your help!

"32 bits mode" does not limit Mac OS X to 4GB or 6GB. Mac Pros could go up to 32GB of RAM, even when they were first introduced with Tiger (10.4) as the OS.
The current iMacs use the 32-bit kernel by default (to maintain compatibility with third-party extensions that have not been upgraded yet). However, it is fully capable of running 64-bit processes (system processes and applications) and using as much RAM as the Mac in question is capable of using, whether that is 4GB, 6GB, 8GB, 16GB, or 32GB.
So to summarize, the RAM limit is based on the hardware, not the software. This isn't like Windows, where 32-bit Windows has a usable RAM limit of somewhere between 3 and 4GB.

Is possible to execute the same executable vi more than 1 time (like notepad, for example)?

I have a Labview executable file that use serial ports to communicate with other devices. I need to execute the same "file.exe" more than 1 time, to control different devices simultaneously. When I double click on an executable been executed (from windows explorer), the file under execution comes to front. Is possible to execute the same file more than 1 time (like notepad, for example)?

Not the answer you are looking for I know..but still: Copying the application to another location is one possibility...if it has a different path it will execute separately.
(OR - build control of multiple devices into one and the same application... If you do not want to redesign the code to handle multiple instruments in the same VIs, you could clone the VIs within the same application...)

Display more than one line of text for events?

I couldn't find this in the forum... I just recently updated to Leopard. Now when I put events in iCal, it only displays one line of text in the month calendar view. I'd really like to see the whole description of the event, even if it's two or three lines. I can't find anything in preferences that addresses this, and various searches are not yielding anything. Help?
-mel

Hi there.
Usually in iCal if you want more than one line of text for timed events, resizing the window will help. Under all-day events, iCal will always show you one line of text, but if there is more space it will show you more text. So, also resizing the window for this will help to see the text.
Take care.

Why does iPhoto (9.0/11) not retain the Event name when exporting more than one event? (using File - Export - Album name with number).

Why does iPhoto (9.0/11) not retain the Event name when exporting more than one event? (using File -> Export -> Album name with number).
Exporting a single Event retains the Event name which is what I'd expect. But highlighting more than one event and exporting it renames the images to Events 001.JPG, Event 002.JPG etc.
I was recently on holidays and had all my events nicely split on Dad's computer but when I went to export it I couldn't retain any of this information. Now I have to replicate this all again on my computer.
It wasn't possible to export the entire library as the external drive was fat32 format an I didn't want all of it. It would be nice to export a bunch of events to someone and have it retain the name.
Does anyone have a work around or will this be fixed at some point by Apple?

Unfortunately no, It says "Adobe not responding" as well when I try to open a pdf. It has done this a few times where I had to uninstall and reinstall. Also, Illustrator tells me to uninstall/reinstall as well.

Can I have more than one routing status 4 for one product?

Can I have more than one routing status 4 for one product in R/3? What impact will have this routings on Financial departament?
I am working in PP and | want to implement perfect planification, but I don't know if I have 2 routings for each equipment.
And also each routings status 4 will have his production version, can financial to do corect calculation?
Thank you!
V

Hi Mangalraj,
My question is about the impact on financial calculation. I know I can have more 2 or more than that active routings status 4.
I want to know how the financial SAP guys decide which routing to chose when they run the final month calculation. Or can they make a sum of all routings I have?
For example if I have:
- 3 SMT line where I produce one product. So, I want to have dedicate routing for each line and production version.
In this case if we produce:
200 part on the first line wich have machine time equal with 4h/100pcs
800 part on the second line with have machine time equal with 2h/100pcs
on last one we don't produce now but this have machine time equal with 5h/100pcs.
I want also to mention that all operations in all routings are marked CostRelevncy.
So, the production planner will have the perfect planning But how is this for financial SAP specialist? Is easy to manage?
Thanks,
Versor

Controlling more than 4 motors simultaneously using 7344

Is there any way of controlling more than 4 motors by using a multiplexing scheme. or can it be done in any other way.

The 7344 supports four motors (servo or stepper) simultaneously. As long as you are using stepper motors you could also think of switching the motion signals with an external relay multiplexer to more motors but then the multiplexed motors couldn't run in parallel. Depending on your application this would mean that you would have to switch a lot of signals (step, direction, limit switches, inhibt outputs,...) and I don't think that this would make much sense. With servo motors this approach wouldn't work anyway as the control loop would be interrupted.
If you want to control more than four motors you better should use another PCI-7340 (2 or 4 axes) or a PCI-7350 (2, 4, 6 or 8 axes).

Has anyone ever been quoted more than $500 to replace a failed logic board?

Has anyone ever been quoted more than $500 to replace a failed logic board? A Genius buddy of mine swears that it'll never be over $500 but I' convinced he's high out of his mind.

I doubt it. They don't even take the same kind of RAM.
What makes you think a replacement "will most likely go bad in the future"? Some have had to go back more than once; many haven't. (And many have not gone in at all.) There are many iBook users out there, happily iBooking away without any knowledge of the iBook Logic Board Repair Extension Program because they've never had a problem.
Get it replaced, free, NOW, and worry about the future when it gets here.

Force VM Buffering to Use More than 3.5GB RAM - Good Idea?

Sorry if this was explained, but I didn't see the short answer in any of the other threads I just stumbled on (and it sounds interesting).
First: Download and Info:
http://kb.adobe.com/selfservice/viewContent.do?externalId=kb402029&sliceId=1
The information about VM Buffering in Photoshop CS3 is confusing at first glance.
First it says it gives PS access to about 8GB RAM and speeds things up, then it says it slows things down.
What might be the short recommendation on 2008 Mac Pro 2.8 8-core, 4 internal SATA (no RAID), 10.5.2 Leopard, 14GB RAM?
Files range from 20MB-1GB.
Should I be using these plugins?
ForceVMBuffering.plugin
DisableVMBuffering.plugin

>Just to be sure now, if I install ForceVMBuffering plugin, Photoshop CS3 will use more than the 3.5 GB?
As long as we're clear on what "use" means. The primary function of the VM buffers is to put as much scratch data as possible into RAM, instead of using the normal and much slower scratch hard disks you set in Preferences. That means if you are using a file so small that Photoshop wouldn't need to swap out to the scratch files, you may not see it take much high RAM. Also, my understanding is that because buffering is only about scratch files, it does not help provide more RAM to calculate a single operation, such as a running a complex filter on a very large layer. But if you never see "out of RAM" errors (and most people don't, because Photoshop is already well optimized), you don't need to worry about having enough RAM for operations. You only need to be concerned about using any extra available RAM for performance-enhancing memory buffers, and that's what Photoshop takes care of with VM buffering.

Using more than one PU and PC for the same database

I have a scenario described here: [http://www.seamframework.org/Community/UsingTwoParallelNestedConversationsWithParentAtomicConversation|http://www.seamframework.org/Community/UsingTwoParallelNestedConversationsWithParentAtomicConversation]
which uses Seam, EJB3, JPA, Hibernate, Richfaces (modalPanel) and JSF.
The question I have is the following:
is there any negative consequence (memory consumption, performance hit, etc.) of using more than one persistence unit in the persistence.xml that points to the same EntityManagerFactory? I was thinking of having one PersistenceContext (Seam-managed PC - an extended PC which is conversation-scoped) which uses one PU and reserving the other PC for the modalPanel forms and backing beans (SFSBs).
The reason I needed to use this solution/approach is so that when using Hibernate MANUAL flush with SMPC, I can achieve isolated synchronization of the PersistenceContext without updating values in the modalPanel forms and vice versa.
Any tips on best practices or alternative solutions? thx.
persistence.xml snippet:
   <persistence-unit name="boBETS">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>

   </persistence-unit>What happens if I were to have 10 PUs and 10 PCs in the same app? Whether they're all pointing to same DB or not. What's the consequence of using "too many"?

Yes, you can use multiple iCloud accounts in multiple User Accounts on one computer, but, as you know not multiple iTunes Match accounts. Keep in mind that the two services are not the same.
Since you've posted your question to the iTunes Match forum, which it really doesn't pertain to, you might want to also post it to the iCloud on my Mac forum.

Z77A-G45 start up-shut down loop with more than 1 stick RAM

New Build, personal use and doing it myself:
BOARD: MSI Z77A-G45
BIOS: *?* click-bios reports "E7752IMS V2.5", but "MS-7752 VER: 1.4" printed on board?
PSU: Thermaltake 850-watt Black Widow 69A 12v rail
CPU: Intel Core i7-3770K BX80667i73770K - Quad Core, 8MB L3 Cache, 3.50GHz, 77W, Unlocked, fan included, no extra cooler yet
MEM: Corsair Vengeance CMZ8GX3M2A1600C9B 2x4GB 1600 MHz, 9-9-9-24, PC3-12800, 1.5V
HDD: WD Blue WD10EALX 1TB, SATA 6Gbs, 7200RPM, 32MB Cache
CASE: Thermaltake VN770M1W2N Overseer RX-I Full Tower
OS: Win7 Pro 64-bit
System bought as bundle including the 2x4GB Corsair RAM. Assembly went well but took me a long time to make sure I had it all right. Then, nothing happened at power-up, no lights or anything. My first reaction was to replace the included Thermaltake power supply (700 watt 52A 12volt rail) - I disconnected all power to the unit and removed the original psu and, on a whim, I booted up with the original power supply outside the case and the lights came on with the psu laying on it's side! Got the start-up and shut-down loop (lights up and spins all fans for a few seconds, then shuts down and repeats ad infinitum), which I was not expecting. Replaced the original power supply with the Black Widow (specs listed above) and got same shut-down loop.
Started checking the memory sticks one at a time in DIMM2, each produced that shut-down loop. Also tried with two sticks of Patriot Viper 3 PVI316G160C9K 2x8GB 1600 MHz, 9-9-9-24, PC3-12800, 1.5V (which doesn't appear on MSI's compatible list...but I had it handy) Then, With the last 8GB Patriot stick in DIMM2, I finally let it go through that shut-down loop 5-6 times out of frustration, and then it suddenly powered up "normally"!
I took advantage and have smoothly installed Win7 Pro, and mobo drivers from CD, no glitches, USB working fine. Then tested each stick - all 4 RAM sticks work individually in DIMM2, but the board will not accept a 2nd stick in 4 without that same shut-down loop (tried using either matched pairs). Manual specifies using DIMM2 and 4 (which are the black ones) for dual channel. Have also tried slots 1 and 3 (blue) with same shut-down loop results, no BSOD or error codes, not even any beeps. Computer boots normally and runs Win7 just fine with one 8GB stick in DIMM2. Also boots Windows and runs fine with one 4GB Corair chip in DIMM2.
Have done CMOS clears and also re-seated the cpu and heatsink/fan, and all pins and board connections looked OK.
Have some problem getting into the BIOS screen to look at things - seems to boot up so fast with a re-start that Delete key and F11 don't quite catch before Windows starts (8-year-old Logitech USB keyboard?). Have to completely power down and start up to get into BIOS, but that doesn't always work either. System recognized the memory change to the Corsair stick, but the screen went by so quick I couldn't catch it to get into BIOS.
Questions:
1) I've searched this board and read for hours about similar shut-down loops problems, but either nothing seems to match my particular quandary or I don't know what to look for. I don't understand what's happening with this shut-down loop - since all four sticks work individually in DIMM2, could DIMM4 slot be defective and I need to RMA the board?
2) I have not yet removed the board and tried to start it outside the case - could a short be causing the 2nd slot to malfunction? Standoffs are built into the case but they didn't seem too low, and the amount of standoffs matched the mobo mounting holes wiwth nothing else protruding. It's a really solid board that did not bend when being attached. It's also possible to look down behind the board with the front cover off and see that nothing is touching it. Will breadboard it next, since I have to take it out, anyway.
3) Where exactly is the Bios version printed on the board? Click Bios reports version as 2.5 but appears that 1.4 is marked on the board. Have done no updates of any kind, only thing I did was disable the splash screen so I could see POST (like I could read that fast...!). Do I need to contact MSI to find out what Bios version actually shipped with this board? It's OK if I got an older board with updated BIOS, but it's confusing when something different appears to be printed on board.
Additional info: Phase lights - LED is lit and all lights flashed at boot-up. CPU temp running for three hours idle is steady 37-38C, mainboard system temp 25C. Went with a larger power supply because I intend to use Crossfire and more drives in the near future, but using onboard video for now. System to be used for graphics/video processing with multiple programs running.
I'm currently working from an ASUS M3A78-CM board with AMD Phenom 9650 2.4 GHz. I've never dealt with an MSI or an Intel system before, and the Click-Bios is something new to me. Alas, I'm not an expert, but I've followed the basic steps I knew. What did I do wrong, overlook or just plain don't know? I sure would appreciate another opinion before I give up. I'm amazed at the speed of this motherboard/CPU combo - it's probably more than I need, but I'm intrigued to figure it out.
Looking forward to those opinions,
Jilliebob

Do this, and while it is in the open re-examine your cpu pins w/ a bight light and hd zoom or a magnifying glass.
Thanks, xmad, I'll look at th CPU again tomorrow/next day under the glass when I take the board out. I already checked them under magnification and was leaning toward a funky board, but it never hurts to re-check. Eyesight is not what it used to be, for sure (I miss DOS, if that's a clue...). Don't want to flash the BIOS if not necessary, since it runs Windows fine and everything works except that RAM.
Bernhard, I don't have CPU-Z installed on that machine and don't want to install anything else until it's working normally. I'd never seen Click-Bios before and just need to get over my initial suspicion of something new! Also learn my way around it before I change anything. I'd never encountered a board reporting a bios different than printed on it. I've never messed with manual memory settings or done more overclocking than just a little exploratory and suprisingly successful nudge - if you could point me toward a good basic explaination of all those settings, I could learn from there.
Appreciate your input very much.
Have learned a lot just reading the threads here for the last few days. This is the best forum I've ever encountered. I'll report back - some suggestions in other posts resembling my problem ended with no resolution, and that's a shame because one doesn't know if it worked or not.
