Best Amount Of RAM For Web / Media Designer?

Hello Everyone,
First post and jumping right in.
I'm moving to a MAC permanently and this will be my first purchase (iMac 27" Quad Core). Can anyone tell me the most suitable RAM upgrade I'll be needing? My budget really doesn't allow for the 16Gig right now unless it's really needed.
I do run mostly the Adobe CS line sometimes 3-5 programs at once (Photoshop - Dreamweaver - and most memory hogging-ly Premiere). Soon I will be getting into Final Cut Pro.
Needless to say aside from a myriad of other issues performance and lag-time is why I'm jumping ship from PC.
Does everyone think I'll be pretty satisfied going with 8Gig of RAM to start or given the above info am I wasting time not going straight for the 16Gig?
I've spoken with a few designers and they've told me while the Mac Pro is incredible - it's overkill for what I need storage and ...well...everything else wise and the common saying has been - get the iMac and upgrade the ram.
So I humbly ask you experts. To summarize my wordiness above
8 or 16? What are your thoughts as well as any other great add ons that could be of use to a designer with a large check from a recent project burning a hole right through his pocket?!
=)

I would recommend adding 2 x 4 GB for a total of 12 GB; you can then see if that will be enough. Please note: there have been posts here regarding problems of the new iMacs when adding third party RAM for a total of 16 GB; there have been no problems reported if the 16 GB is OEM RAM (such as Samsung or Hynix, which is what Apple has been using). So, if you intend to keep the original 2 x 2 GB, then I'd suggest adding 8 GB.
That is what I did; I do a fair amount of video editing and the iMac is doing just fine with 12 GB. Also, iMacs are quite finicky about their RAM - do not buy any brand "value" RAM - stick with quality RAM from reputable vendors with lifetime warranties, such as OWC (macsales.com) or Crucial (or Samsung which will be more expensive).

The amount of ram for g4/800

ok so i took my g4 imac to our local mac shop, and tried to get up to 1gb of ram, when i went to the "about this mac" it said it had 512mb so i had to get another 512mb for 1 gig. no big deal. so i go to the store and when i get it back it only has 768mb, and they said it really only had 256mb of ram for some reason. and they said you cannot get 1gb of ram. is this true? ive been looking around these forums but nothing seems to clearly answer my question?

Hello and Welcome to Apple Discussions.
The iMac G4 is a funny beast when it comes to RAM. There are two RAM slots one called "user-accessible" and the other "factory-accessible". Apple installed all the RAM originally ordered in the "factory-accessible" slot so you would have 128MB, 256MB or 512MB installed in there.
The "user-accessible" slot would be empty for users to upgrade at a later date.
Click to enlarge.
I suspect that you had a 256MB in the 'factory' slot and a 256MB in the 'user' slot when the shop upgraded they only replaced the 'user' with a 512MB to give you that 768MB total. For anyone who knows iMac G4s, upgrading the 'factory' slot is not difficult I took the photo above for example.
I hope the store didn't charge you a fitting charge for the user-slot installation and it's a two minute job that anyone is capable of. The factory slot installation is probably a thirty-minute job and is more complex.
To confirm my suspicions have a look in  menu > About this Mac > More Info...:
Check you have a 256MB and 512MB.

Maximum speed and amount of RAM for m7664x

I have an m7664x that I will be upgrading to 64-bit Windows 7 and I want to upgrade the RAM.
According to the product specs, it has the A8M2N-LA (NodusM3) motherboard with 4 DIMMs. On that page, it says that it supports up to 4 GB of RAM at 667 MHz.
Now, I've come across a few posts here and elsewhere that suggest that it can handle more (up to 8 GB) and higher RAM speeds (PC6400 / 800 MHz) and have it recognized and utilized.
Can anyone confirm that it can support up to 8 GB of RAM and with higher speeds?
This question was solved.

Two weeks ago I installed 8GB DDR2-800 into my stock m7664x and all is still working fine. The BIOS setup shows 800MHz, and the memory test passes with no issues. For the record:

Suggested RAM for weblogic 4.51?

Hi all,
for a "medium-sized" web application, with a requirement for 1000 concurrent
users, is there an optimal amount of RAM for the system? All weblogic says
is that 64MB is required to install, but
it says nothing about the RAM-vs-load curve. Is 100MB (what we currently
have) way too low?
Am I correct in thinking that, however much RAM we put into the system, we
should set the starting and max heap size to 80% of that amount in
startWebLogic.sh?
Thanks

Maximum RAM for Mid-2010 iMac 3.2GHz w/ Core i3 Processor?

I am looking to upgrade the RAM on my iMac. This is the first time I've ever done so and the reason for it is that I'm finally starting to experience some noticeable lag while playing games. I'm not a hardcore gamer by any means but I feel as though the kinds of games I play shouldn't be struggling so much to run. Some examples of games I've played that have had trouble include Amnesia: The Dark Descent and Left 4 Dead. These games came out a few years ago so it's not like I'm pushing the limits of my machine here! I've done quite a bit of research online but I've come across some conflicting reports on the maximum amount of RAM I can install.
Apple's support files state that the computer can hold up to 16GB of RAM, but then go on to state that this would be equivalent to a 4GB SO-DIMM in each slot. Is that because there are four total slots in my iMac? (See... I told you I'm new at this!)
At the same time, I've also read that it is possible to install up to 32GB of RAM in this particular model of iMac. Is this actually true?
Whichever the case may be... can anyone recommend some good, quality, dependable brands of RAM? Because in doing my research I've read a few horror stories about faulty RAM (and no... I'm not planning on shopping on eBay so don't worry!).
My final question is this: Is upping my RAM actually worth it? As in, will it help my games run smoother and/or better? I ask because I've also wondered if the video card might be the bigger problem (which I hope it's not because I have no idea if it's even possible to replace that).
Sorry for being so long-winded but I just really want to make sure I do this right and don't waste my money. Thank you in advance for any help! =)

Your computer has 4 slots. When Apple shipped the computer the largest DIMM shipping was 4GB so Apple advertises 16GB as the max. According to OWC that remains the maximum for your computer, only the i5 and i7 models can be upgrade to 32GB. At this time 16GB should be plenty for most people.
There are a number of things that have an impact on speed and, of course, one of them is RAM. When your computer first came out the operating system you were using was less RAM hungry. It seems that each new upgrade (or every other OS upgrade) ups the RAM ante. Other things that have an impact are the utilities and programs you run behind the scenes. They can burn up lots of CPU cycles and RAM. Hard drive space is another factor - the operating system and programs need room for temporary files and when this room isn't available the computer slows down. So, are you running anything like anti-malware? Dump it, not needed. Do you have about 25GB of free drive space? If not, free some up.
Quality RAM - not only what you buy but who you buy it from is important. I go with Crucial or OWC.

How much RAM for ONE App & does OS X limit allocation?

Hello all,
This question concerns how much RAM I realistically need to run ONE application to it's fullest. I mainly use ProToolsLE 7.3, but sometimes use LogicPro 8 and Final Cut Express 4, again, only one running at a time. I've read on the ProTools forum that Windows (yuck) limits the amount of RAM that can be allocated for 1 application. Does Mac OS 10.4 or 10.5 do this?
Right now I have the stock 1GB (2 x 512MB). I plan on pulling it and installing a matched quad of either 1GB sticks (4GB total) -OR- 2GB sticks (8GB total). I understand that matched quads in slots 1/2 of both risers is optimum for the early Mac Pros.
The ProTools forum isn't helping much. A ProTools support person said that starting with 4GB will be good to start and that they test their systems with 4GB installed. What did they mean by "good to start"? Will it increase jumping to 8GB or is 4GB all ProTools can really use?
Another guy on there said "keep in mind that to use 4GB of ram - you'd need a 64bit Operating system (not supported by pro-tools) or on a MAC PAE support enabled, which depending on your hardware may not be a great move." I dont know what that means! Mac OS 10.5 IS a 64bit OS, right? And ProTools 7.4 NEEDS OS 10.5 to run....even if it is only a 32bit app. (though right now I am running PT 7.3 on OS 10.4....not sure if 10.4 is 64bit)
A quad set of 1GB is under $170 and a quad set of 2GB is under $270. Funds are tight right now, but I think I can swing the extra $100 to double the RAM -IF- it will make a difference.
Any thoughts as to wether the extra $100 will be worth it, or am I wasting my money? Thanks!

Hatter,
Thank you so much for your advice! If I may bother you to receive one final suggestion....
Based on the best prices I have found from all of the well known Mac Pro memory dealers, I have narrowed it down to 3 configurations that are balanced. Even though I'm still not 100% confident that 8GB of RAM will give me any noticable imporvement over 6GB, the price is only $42 more to get 8GB. Am I correct in saying that the early Mac Pro would do better to have one matched quad set of RAM over the new Mac Pro's increased performance of having all eight slots filled? Here are the 3 configurations and prices.
4 x 1GB + 4 x 512MB = 6GB Quad+Quad $220 (using my stock 2x512MB sticks)
4 x 2GB = 8GB Quad $262 (pulling my stock 2x512MB sticks)
8 x 1GB = 8GB Octal $278 (pulling my stock 2x512MB sticks)
Which do you think would be the best route?
I already purchased a WD Caviar for my dedicated audio drive. I installed a Seagate 7200.9 in my PowerMac G4 for it's audio drive, but after reading various reveiws, concluded the WD Caviar is a better performer. I LOVE my WD My Book Studio external. I hadn't considered replacing the boot drive, but after reading articles suggesting that it improves overall system performance, and now that you've recommended it as well, I will probably buy a second Caviar for the boot/system drive.
This computer is a DEDICATED audio computer, for ProTools & Logic only....other than a bit of fiddling in Final Cut Express. It's not even connected to the internet and all unnecessary apps are not installed or uninstalled. I also never migrate apps, but always do a fresh install of everything from the ground up.
Thanks again for your advice! It's been a big help!

Out of Ram for cropping

I only have 8gb of ram. But as I track it's use (in an HD 1920x1080 timeline), I find I get Out of Ram messages upon rendering multiple layers of FCP-cropped 2500x2000 RGB jpeg stills. I tried it uncropped and got no error. But ram usage shows no more 5.5 gig of ram. Am I really using more ram than it's showing? Would I be able to perform these feats if I had 12 gb RAM? I seems very sensitive to this type of work.

FCP is a 32 bit application which limits the amount of RAM it can address to 4 GB (2.5 for FCP and 1.5 for related frameworks) Of this 2.5 GB for FCP, you can change the distribution and allocate more for still images. Keep in mind, this is a fixed pool so if you allocate more for stills, you remove it from other uses within the program.
The settings to adjust the memory allocation in FCP can be found in System Settings>Memory & Cache
With more than 4GB of ram in the machine, your Application Use should be 100%. If you are running a lot of larger stills, you might want to bump up the Still Cache an additional 10% -20% or so and see how things run.
Good luck,

What Exactly are the Benefits of More GPU RAM for PP, AE, PS ?

What benefit is there to having, say 4gb GPU RAM over 2gb ?
I have read numerous conflicting, and perhaps misguided, claims regarding when/why one would rather have a graphics card with more than 2gb RAM.
Does this impact effects render, multiple monitor resolution, CUDA, Mercury Playback Engine performance, other areas, etc. and how?
Thanks for your response.
A Ajar

2GB of video ram is more than enough for the Hardware MPE engine and 1080 media with effects. Essentially the greater the ram space on the video card the greater ram caching available for the Cuda acceleration to buffer data ready for GPU processing. The Application memory management ie caching profiles though effect this based on each codec and resolution ie data per frame. However along with this you have to have enough system ram to create the buffers used to cache the data down to the GPU ram since that data shadows down for GPU processing and then back again for final encoding. This means that not configuring enough system ram will limit the amount of GPU ram used. Hence why you want atleast 16GB of ram for HD and the hardware MPE engine. 3GB+ ram spaces on video cards are for 2K to 4K + frame sizes ie R3D and Raw/CinemaDng. This is because the data per frame multiplies significantly when at 4K resolution. This require far greater ram space which is why you look for the 3GB+ ram space cards for those workflows. The Effect data will also increase because there is far mroe resolution data to alter. This is on top of the drawing out data which is what you see on the screen. That is when the differences for the cards show.

Maximum Amount of Ram

I recall reading, somewhere, something that gave me the impression that there was a limit to the total amount of RAM that one can have in a MacBook Pro, and any computer really.
Is this true? And if it is, how can I tell what the maximum amount is that I can put in my computer, or if someone can simply tell me, that works too.

A recommendation for your consideration:
3rd Party sources have you remove the one or two 4Gig cards you have now in your MBP and replace with one(1) with their 8Gig card or two (2) of their 8Gig cards for a total of 16Gigs.
MBP has only 2 memory card slots on 17" MBP (early 2011)
Higher density RAM will be available hence even higher RAM options in the near future.
Big time question would be :"is this an appropriate "upgrade" from a cost-benefit perspective"!!
One wants to optimize NOT maximize in all choices.
Let 'er rip and...

Insufficient RAM for OS X 10.6

When I attempt to update my (early 2006) MacBook with Snow Leopard the computer reports that there is insufficient RAM to run the new running system.
I took my computer in to the Apple store and they said that my RAM is fine. They gave me a new hard drive, and I tried to install Snow Leopard again but with the same results.
What could be the problem? What should I do?
I am afraid that if I go out and buy more RAM the same error will occur, thus a waste of fleeting cash.

If you have the factory amount of RAM (512mb) then it's true... you need 1GB of RAM as a minimum requirement. I suggest 2GB as it's beyond the minimum and it provides your MacBook with the maximum amount for that model. -GDF

Mac pro with 16GB RAM for CS3? CS3 cant use more than 3 GB? why

hi
does it make any sense to buy 16GB RAM for a mac pro
only for working with CS3?
i am retouching prof. and in the moment we run CS2 on the mac pro.
later CS3 is in the pipeline.
we ordered 16GB RAM in order to work with HDR images and big file sizes coming from hasselblad h2 and h3 (300dpi, 23 x 23inch, round 50 or 100 layers, filesize 1 - 2GB per image.)
thanks

found this article @ adobe website
thanks for your help!
"When you run Photoshop CS3 on a 64-bit operating system, such as Mac OS X v10.4 and later, Photoshop can access up to 8 GB of RAM. You can see the actual amount of RAM Photoshop can use in the Let Photoshop Use number when you set the Let Photoshop Use slider in the Performance preference to 100%. The RAM above the 100% used by Photoshop, which is from approximately 3 GB to 3.7 GB, can be used directly by Photoshop plug-ins (some plug-ins need large chunks of contiguous RAM), filters, and actions. If you have more than 4 GB (to 8 GB), the RAM above 4 GB is used by the operating system as a cache for the Photoshop scratch disk data. Data that previously was written directly to the hard disk by Photoshop is now cached in this high RAM before being written to the hard disk by the operating system. If you are working with files large enough to take advantage of these extra 2 GB of RAM, the RAM cache can increase performance of Photoshop.
The default RAM allocation setting in Photoshop CS3 is 70%. These settings should be optimal for most users. To get the ideal RAM allocation setting for your system, change the RAM allocation in 5% increments and watch the performance of Photoshop in the Activity Monitor. You must quit and restart Photoshop after each change to see the change take effect.
The available RAM shown in the Performance preferences has already deducted an amount that is reserved for the operating system from the total RAM in your computer. You shouldn't set the percentage of RAM to be used by Photoshop to 100% (unless you are using more than 2G of RAM) because other applications which run at the same time as Photoshop (for example, Adobe Bridge CS3) need a share of the available RAM. Some applications use more RAM than you might expect. For example, web browsers can use 20-30 MB of RAM, and music players can use 20-50 MB of RAM. Watch the Activity Monitor to view the RAM allocations on your computer.
Watch your efficiency indicator while you work in Photoshop to determine the amount of RAM you'll need to keep your images in RAM. The efficiency indicator is available from the pop-up menu on the status bar of your image or from the Palette Options on the Info Palette pop-up menu. When the efficiency indicator goes below 95-100%, you are using the scratch disk. If the efficiency is around 60%, you'll see a large performance increase by changing your RAM allocation or adding RAM."

Adding RAM for Oracle 9i

Hi,
I have an oracle database 9iR2 installed in my server (32 bits processor, 4GB ram). And I want to add more RAM for oracle database. It is possible? and do I need to do any setting for the previous oracle instance to fit the newly added RAM (Swap space)?
Thank you.
~ vincent.

Hello,
yes, you can add more RAM without any problem. Take into account that if the O.S. it's windows 32b. , it will only see 3,3 GB (unless using PAE). Linux OS has no problem with that.
You don't have to make any previous settings or changes in the database. Just add RAM. After you've added the RAM, the database just will continue using the same amount as before. You'll have to change this modifying all the memory related parameters (SGA, ...)
