Ram usage for MBP

Hello
I have a new MBP and have VMFussion with windows.
Now can someone explain me the activity monitor on Leopard. The CPU is often above 30% and memory is fully use even if I have "given" the VM 1.2GB only.
See here:http://picasaweb.google.com/sezalped/AllSorts/photo#5235691418407380050
Thanks a lot

Your memory is not fully used. You have 1.2 GBs inactive RAM. CPU usage with PC emulation is not unusual.

Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.

  • RAM upgrade for MBP 2.2 GHz Intel Core 2 Duo

    I have a MBP 2.2 GHz Intel Core 2 Duo currently with 2 GB of RAM and with all the work I do on it I would like to upgrade to 4 GB. Purchasing the RAM through Apple is out of the question because it so expensive.
    I would like to know what is the best brand to buy and on what website.. Is an upgrade to 4 GB possible for my MBP? It looks like I have my "Bank 0/DIMM0" filled with 1 GB DDR2 SDRAM 667 MHz and my "Bank 1/DIMM1" filled with the same thing. Does this mean that both of my RAM slots are full AND if I want to upgrade my RAM I'll have to purchase 2 sets of 2 GB RAM? Please help as I am new to all of the tech stuff...
    Another side note... I've noticed that some discussions have stated that some MBP are only upgradable to 3 GB of RAM, but I'm pretty sure that I can upgrade mine to 4 GB of RAM. Can anyone shed any light on this?
    Your help is much appreciated...

    yes, both of your RAM slots are full, so to get 4GB you will have to get 2 2GB sticks. Having the same model I can safely assure you that it will recognize all 4GB of the new Ram.
    as for brands, there have been many I have seen recommended on this board, but one name seems to pop up consistently is Kensington, I picked up my ram from the store I bought my laptop at, so I couldn't recommend a site, sorry

  • 2G RAM stick for MBP 1.83Ghz ???

    The question comes to mind, so is there a 2giga stick of RAM that we can shove in with the 512 "stock" to turbo boost it to 2.5 G,
    (i've already slammed in a 1G stick)
    or am I just dreaming again and have to face reality and buy one of those new super macs, which can run at 4G ? ? ?
    thanks in advance from countryboy

    yeah, Superduper is free, unregistered, some dosh ($'s) if want some privelages for the paranoid,
    one (maybe) more question(s), i'm sure of course (maybe not!) , I plan on using eSATA enclosure, SIIG adapter, for my hard drive which is in my machine now so if I clone to the new drive via eSATA , that's possible yeah, cuz' the superduper site says firewire, but eSATA, it's better, faster, (able to leap taller .... etc !) so that should be alright, no harm in checking though,. . . .
    but in this case why don't i just leave my old hardrive where it is and just connect the new eSATA hard-drive (hitachi) @7200 RPM and that 'll be like a second internal drive with 300mb/s, that's as fast as the internal drives, yeah ?
    so making it no need for cloning, what do you reckon, or it's better to eventuall y install the 7200 RPM hard-drive into the MBP ?
    Hope it's not too confusing this and other of my mac-dillema's
    thanks in advance

  • RAM Recommendations For MBP

    Hi, I just bought a MBP a month ago and wanted to upgrade the RAM to have it run my video editing softwares swiftly. I want to keep one of my original apple RAM sticks in case I have to return the laptop for repairs to apple and they create fuss about it. So I was wondering which is the best RAM to combine with the stock 1GB RAM to have a total of 3GB?
    And also does anyone know what brand of RAM comes with the MBP?
    Thanks

    Hey, Vivz. Welcome to the forum, and congrats on getting a MBP. Good choice.
    First off: Most likely, you have Samsung RAM in your comp. I believe that's what the two latest versions ship with.
    Second: I recommend that you skip right over 3GB and go straight to 4GB. I suggest this for two reasons. 1) It will be faster. 2) The MBP uses a dual-channel system, and you will slow down a bit with 3GB. Sure, you would notice a boost in some apps, but you wouldn't be getting your money's worth.
    I am partial to Kingston RAM, personally. It comes with a lifetime warranty, and it's simply amazing. I recommend a Kingston 4GB Apple Notebook Memory kit from Newegg.com. That's what I use, and WOW is it much faster. Make sure you get the APPLE memory. If you get regular PC RAM, it may or may not work correctly. That happened to me on my other Mac.
    Here's a link: http://www.newegg.com/Product/Product.aspx?Item=N82E16820134560
    For $90.00 USD, that's a great deal. I've had absolutely no problems with mine.
    By the way, are you sure you have 1GB stock? The new MBP's ship with 2GB standard.

  • DVD RAM Drivers for MBP?

    Does anyone know of a 3rd-Party driver that allows us MacBook/MacBook Pro users to take advantage of DVD-RAM? I know older desktop systems allowed this feature.
    Cheers

    I assume you're looking to write to DVD-RAM disks? The MacBook Pro will read these disks, but not write to them. In order to write to one, you'll need to purchase an external drive.

  • MacBook Pro very high overall RAM usage

    Hi, I'm using a late 2012 13" MacBook Pro with 8GB of RAM and a dual core i7 and I've been experiencing very high RAM usage for the last couple of weeks even though I'm not really doing anything. Here's a activity monitor screenshot
    As you can see I'm only really using Chrome and Sublime Text (3). Twitter and Outlook are also open but don't take up that much (Twitter maybe but that just seems to be badly optimised and it's all gone when I close it).
    So, is this normal?
    Thanks in a

    This is normal. The two most important things in that screenshot are 'Swap Used' (0 means you never ran out of RAM) and the Memory Pressure graph (everything green = good). For the rest the OS knows to handle RAM,

  • Limiting OS RAM usage

    I am looking for some tips or best practices to get the most efficient use out of my RAM, particularly when it comes to the OS. I have a Latitude E6530 with 16GB of RAM. I started out with 4, then went to 8GB, then to 16. I run the same number of programs
    in my daily routine, yet it seems that the more RAM I install, the more the OS gobbles it up. Since I run the same programs daily, I would not expect RAM usage to fluctuate very much and expect these apps to consume about the same daily. It seems like the
    only thing that can be consuming more RAM is the OS. When I was at 4gb, I hovered around 70-80% RAM utilization, went to 8GB, same results, now at 16GB, and almost hitting that number again. I understand the OS needs a certain amount of RAM to operate, so
    is there a way for me to limit what the OS takes so I can have more for programs that may need it? Will the OS "give some back" if needed to extra programs I may decide to run when I am at a high utilization mark? What I don't want to get into
    though is a constant swap condition, especially with core OS components that need to stay in RAM. Whats the best way to go about this?

    it will be better if you start from "general" about RAM management
    http://windows.microsoft.com/en-us/windows/optimize-windows-better-performance#optimize-windows-better-performance=windows-7
    actually its not only based on how much RAM that you are using, but how you prevent another program or HW attached (even external graphic card or LAN card) used windows service that maybe will increase RAM usage.
    You can start using Windows performance tools to investigate
    http://technet.microsoft.com/en-us/library/cc749249.aspx
    try to compare different condition like, a few program running during start up (clecan boot), disable security software, no other 3rd party HW attached, no internet connection, upgrade latest driver for all HW or else
    my opinion, Windows will only using RAM that needed to run start up, increasing RAM usage for windows process depend on the software running and HW attached 
    for more details and complicated process :) , you can read and implement this with your development environment

  • RAM usage: MBP vs PB

    Call me crazy, but I have the feeling that the MBPs use more RAM with the same apps than the PB. I used to have a 15in PB with 2GB of RAM and now I have a 15in MBP with 2GB of RAM. So, technically I have the same RAM in both portables. In both computers I have the same apps launched upon login. Activity Monitor is one of them and always shows the RAM usage. It is slightly higher on the MBP and the more apps opened in addition to those, the more distance you can see comparing one another.
    It seems like the every app consumes a bit more RAM within the MBP and all put together just makes more evident the difference. And I wonder why?
    And I also wonder, isn't the same thing with the OS, I mean, doesn't Tiger for Intel processor takes more disk space than Tiger for PowerPC? Here I'm not entirely sure, just guessing.
    George...

    And I wonder why?
    If the applications you are using are PowerPC rather than Universal/Intel binaries then your answer is called Rosetta. For instance, under the same conditions Micrsoft Word 2004 will use 200MB or so more on an Intel Mac than it will on a PowerPC Mac.
    If you are using a Universal application on both, such as FileMaker Pro 8.5, then they should more or less use the same RAM.
    doesn't Tiger for Intel processor takes more disk space than Tiger for PowerPC?
    In Tiger's case I believe as there are PowerPC components that are required. The difference with Leopard will be negligible as it will be a complete Univseral binary OS.
    Ultimaetly though… after all the dust settles with the transition and PowerPC binaries are no longer needed (ie, everything we use is a Universal or Intel binary) the amount of both disk and RAM usage should be pretty similar.

  • NEED HELP ASAP on RAM for MBP Unibody 15"

  • Buying RAM for MBP

    I just bought a MBP with 2GB preinstalled, expecting to upgrade to 4GB through a 3rd party in order to save money. I was going to go with newegg.com's RAM, but now after thinking about it I'm starting to have cold feet, and there are a few things I need to straighten out before making the purchase.
    First of all, is there any difference between the apple 2x2GB sticks for $180 and a 3rd party's for $80-$140? I'm a bit nervous about "getting what I paid for". It seems like the only difference would be the warranty that apple has, and even the sales guy at my local apple store said he would reccommend buying RAM through a 3rd party as long as I'm comfortable with installing it.
    Second, on newegg.com the RAM products are titled "Company Name" 2x2GB RAM for apple notebook model "Then a string of letters and numbers, presumably the model number". But when I checked the model numbers of MBPs, none of them matched the model numbers that the RAM was for, and to make matters even more complicated, there are customer reviews on the site saying that they bought the RAM for their MBP and it worked great.
    Third, if I do decide to go with a third party, is there any difference in quality between the $77 Patriot RAM and the $140 Corsair RAM as long as they're all DDR2 667?

    Your model requires PC2-5300 DDR2 667 MHz SDRAM as set forth in the technical specifications in your computer's User Guide. Any brand RAM with those specifications will work. You will often find retailers offering two variations: an "economy" price for product that carries at best a one year warranty (sometimes it's unbranded or retailer branded); and the regular branded product that carries a Lifetime Warranty. The latter is higher priced but is what you should purchase.
    Prices will vary so do some shopping. As long as the product comes with the Lifetime Warranty and the reseller has reasonable return policies in the event you get a defective product, you need not be overly concerned about who made the RAM or the retailer from whom your purchased it.
    Some reasonable sources are:
    DataMem.com
    NewEgg.com

  • I need a little advice on chosing RAM brand for my MBP

    Hi, from France !
    The computer store just next where I live has these 2 brands of RAM, and I am not sure which I should chose, so I was wondering if someone with experience could give me a little advice on which brand I should go with
    This is what they have :
    • Corsair : http://www.ldlc.com/fiche/PB00071269.html
    • G. Skill : http://www.ldlc.com/fiche/PB00080116.html
    (both 200 pins, unbuffered *(should I go for buffered, what's the difference ?)*, DDR2 667, PC2-5300)
    +(this is for a MacBook Pro 2,33Ghz Intel Core 2 Duo (late 2006))+
    Thanks a lot, do not hesitate to give your opinion even if someone else already answered !
    (oh and extra bonus question, what benefit would I get by spending more money on ram for this kind of computer ? any suggestion on something else that would really rock ?)

    Honestly, either is fine. There's no meaningful benefit by spending more.
    RE buffered vs. unbuffered - essentially, unbuffered is what you want (buffered/registered RAM is for server applications).

  • RAM Upgrade for Late 2009 Mac Mini -- anyone tried 16gb?

    Just a stupid question.. I've got a Mac Mini server (late 2009) that came with 4Gb of RAM.. The machine has never been speedy by any means and after finally getting some time to look into why, I think I know mostly why.. I've got the machine setup handling DNS, email (with Amavis, spam handling,etc), both MySQL and Postgres databases, Apache+WebDAV+iCAL and of course handling 2-3 user accounts being logged in at all times (using iTunes, Safari, etc).  if I pull up Activity Monitor or use the "MemoryStick" utility, I see that my RAM usage is typically (almost always) at about 96% used with 7 swap files running.. I've never seen it below about 95% used.  I know that this machine is capable of being outfitted with 8Gb of RAM (although Apple does not necessarily endorse that config).  So, this leads to my next question -- has anyone taken some 8Gb RAM modules such as these : http://eshop.macsales.com/item/Other%20World%20Computing/1333DDR3S32S/  and tried plopping two of them in to see if they're recognized as 8Gb modules and used or not?  I also have a brand-new 15" MBP (2011 model) that seems to occasionally suffer from the same fate -- it's also got 4GB of RAM and last night for quite a while it was at the 90% utilization level for RAM as well while importing some videos in iMovie '11..
    I'll have to admit that I'm wondering whether 8Gb is going to be enough RAM for my purposes on the mini.. I suspect I'm probably asking it to do too much -- all of this used to be done on an older model HP Proliant server (quad CPU, hot-swap drives, redundant power supplies,etc) -- but it cost about $40+ per month in power alone..
    Anyone?

    Thx.. I've actually upgraded to a new 2011 Mac Mini which can still take those same 8Gb ram sticks.. Interestingly enough the new Mac Mini server still comes with a measly 4gb of RAM which just doesn't cut it with OSX Lion -- I'm constantly at 1% free RAM when I've got Mail.app running.. Ugg.. Hopefully once I put 12Gb or 16Gb in, it'll hum along..
