How much is my computer worth ?

Hello,
I'm planning on buying a Macbook Pro 2012 but I'd like to do something of my Macbook that's been my faithful compagnion so far. To this day, I still don't know whether I want to give it away or sell it, but this is why I'm gathering informations.
I have no idea of much my computer is worth today and I was wondering if you all, could help to price it.
Bellow : Screenshots of my computer's configuration, it is all in French but I'm sure it'll be easy to decipher, if in doubt though, don't hesitate to ask me.

Thank you in advance !

Have you tried looking around on craigslist, ebay? It might be able to at least provide you a range to price it at. Just look at what others are selling theirs for and if you are really looking to absolutely get rid of it price it slightly lower then the norm. If you really dont care about getting rid of it to quickly and would rather get a little extra cash then price it at the higher end of the range they are going for.

My laptop has 1g ram i need to know how much ram this computer will handle, i have a dv6426us

I'm needing to upgrade my RAM I have a total of 1G now, I need to know what this particular laptop will handle. The OS is Vista Home Premium and it takes as much as 2 hrs to reboot sometimes
I have a Pavillion DV6426US Entertainment Wide Screen
Thanks for any help that you can provide

Hi:
You can install 2 x 2 GB of PC2-5300 memory (total of 4 GB), if you have BIOS version F.25 or newer installed in your notebook.
Maxing out the memory should help the performance, but you should look into removing any unnecessary software and stop any unnecessary programs from running at startup.

How much and what kind of memory can I install to upgrade my G72-b57cl notebook?

I have installed what I thought was the recommended memory for my G72-b57cl notebook, but I cannot get windows to boot or recover after installing it. The BIOS recognizes the memory and a memory check also recognizes it, but windows 7 64-bit will not operate. Is it the memory or windows?

Hi:
Below is the link to the service manual for your notebook.
http://h10032.www1.hp.com/ctg/Manual/c02623152.pdf
Memory upgrade info can be found in chapter 1 on page 2.
Max is 2 x 4 GB (8 GB) of PC3-1333 memory.
You have to pay particular attention to the fact that HP notebooks need PC3-10600 memory.
There are some memory modules out there which are PC3-10660 or PC3-10666.
The above 2 variations will normally give the user problems.

Where can i find how much ram my computer can use?

I looked in the "about my mac" section, no info on max ram. I have a 2.33 intel core 2 duo. 15 inch.

I usually use this memory finder at crucial.com
Just choose Apple from the list of manufacturers, macbook pro for the product line, and then your specific model under model.

How much memory an object consumed?

Via making an internet lookup and writing some code, i made an implementation of
how to calculate how much memory an object consumes. This is a tricky way.
However, how can i achieve a better and direct way? Is there a tool for attaching
to JVM and viewing the memory locations and contents of objects in memory?
I wrote the tricky way to Javalobby and pasting the same explanation to here too.
I must say that this tricky way does not belong to me, and i noted where i took
the main inspiration etc. at the end.
Because of the underlying structure Java does not let
users to access and directly change the content of
instances in memory. Users could not know how
much memory is used for an object, like in C.
However this tricky method lets them to know in an
indirect way.
To achieve how much memory is used for an object we must
calculate the used memory before and after the object is
created.
MemoryUsage.java
* User: Pinkman - Fuat Geleri
* Date: Mar 20, 2005
* Time: 11:13:50 AM
* The class which makes the calculation job.
* Calculating the difference of used memory
* between calls
* "start()", and "end()".
* So if you initiate an object between those
* calls you can get how much memory the object
* consumed.
* Initial inspration from
* http://javaspecialists.co.za/archive/Issue029.html
public class MemoryUsage {
     long usage;
     public void start(){
          garbageCollect();
          Runtime r=Runtime.getRuntime();
          usage=r.totalMemory()-r.freeMemory();
     public long end(){
          garbageCollect();
          Runtime r=Runtime.getRuntime();
          return (r.totalMemory()-r.freeMemory())-usage;
     public String memorySizeToString(long l){
          int MB=(int) (l/1048576);
          l=l-1048576*MB;
          int KB=(int) (l/1024);
          l=l-1024*KB;
          return new String(MB+"MB "+KB+"KB "+l+"BYTES");
     private void garbageCollect() {
          Runtime r=Runtime.getRuntime();
          r.gc();r.gc();r.gc();r.gc();r.gc();
          r.gc();r.gc();r.gc();r.gc();r.gc();
          r.gc();r.gc();r.gc();r.gc();r.gc();
Therefore the first file MemoryUsage.java is coded.
It simply calculates and stores the used memory when
start() method is called. After generating some objects,
the end() method is called to get the
difference between memory usages, between the start()
and end() method calls.

* Arbitrarily size of objects in JAVA..
* An example of getting how much an
* object consumed in memory.
* Like
* primitives -> does not consume any
* arrays -> consumes 16 bytes when empty
*   ex: byte []a=new byte[0];
* list    -> consumes 80 byte when empty..
* references -> when did not initiated does
* not consume any memory!.

        SizeOf s=new SizeOf();
          s.sizeOfExample();
     //remove the comments in order to make the same checking by yourself..
     private void sizeOfExample() {
          mu.start();
          //byte []b=new byte[0];//<-byte array 16byte,each byte addition equals 1 byte!!
          //String s="How much memory is used?";//string consumes no byte!!
          //byte c=20; //<-consumes no memory!!
                //Object o=new Object();//object consumes 8 bytes..
          //Object []oa=new Object[100];//<-object array consumes 16 byte! and each addition object 4 bytes!
                //List list;//non initialized object consumes no memory!!..
          //Integer i=new Integer(1);//an integer object consumes 16 bytes!
          //List list=new ArrayList();//An array list consumes 80 bytes!.
          /*for(int i=0;i<10;i++){ //An array list + 10 integer consumes 240 bytes :)

          byte []rand=new byte[1];
          int count=100000;
          List list=new ArrayList(count);
          for(int i=0;i<count;i++){
               r.nextBytes(rand);
               list.add(new String(rand));//empty string occupies no memory??
          DefaultMutableTreeNode root=new DefaultMutableTreeNode();//8 byte when single!.
          Random r=new Random();
          byte []rand=new byte[10];//when this is one and count is 1 million memory gets overfilled!..
          int count=500000;
          for(int i=0;i<count;i++){
               r.nextBytes(rand);
               root.add(new DefaultMutableTreeNode(new String(rand)));
          long l=mu.end();
          System.out.println(""+mu.memorySizeToString(l));
An example usage can be found in the second file
SizeOf.java. Simply remove the comments,"//", and execute
to see how much memory used.
For example:
% Primitives does not consume any memory.
% Non-initialized object references does not consume
any memory.
% Empty string and most of the small strings does not consume any memory.
% Empty byte[] consumes 16 bytes.
% Empty ArrayList consume 80 bytes.
% An Integer object consumes 16 bytes.
% Empty DefaultMutableTreeNode consumes 8 bytes..
and so on.
You can find the mentioned files in the attachments.
I heard the idea of -how much memory is used- from
Prof. Akif Eyler, and i got the main inspration from
the site http://javaspecialists.co.za/archive/Issue029.html
//sorry about my mistakes, and everything :)
Thanks for your answers beforehand.

Any good profiler will tell you.
You can also code your own using jvmpi or jvmti.
Also note that calling System.gc is a hint to the jvm it may or may not respect your wish.
Test it with a few different gc algorithms and see what happens.

How much RAM is my blackbook addressing?

i have a 2.16 blackbook. i recently swapped out the 3gb (1gb+2gb) ram i had for 4gb (2x2gb). i read that my version of the blackbook can only address ~3.3gb with 4gb installed, but so far, i can't find any evidence of that. both activity monitor, terminal's top program, and about this mac seem to suggest that my computer is addressing all 4gb ram. is there something i'm overlooking? is there any other way to figure out how much ram my computer is addressing? thanks.

It does not. Activity Monitor reports:
Wired RAM
Active RAM
Inactive RAM
Free RAM
The total is your installed RAM.
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
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.

How much is too much music on itunes?

im uploading a lot of music onto my itunes, for two different ipods, and i dont know if i put too much music on if there will be a lag or anything
can someone please tell me how much music a computer can take before significantly slowing down?

As long as there's at least 1GB of space free on the hard disk at all times and the iTunes library isn't stored on the Finder's desktop, you shouldn't experience a major slowdown regardless of how big the iTunes library gets.

How much can the 16gb ipad3 and the 32gb ipad hold on their storage (apps songs books, etc)

I am just wondering which is better value for money, and how much different stuff each size Memory can actually hold...

a 16 gig iPad usually has 14 and change free after the operating system. the 32 gig has 29 gig and change free.
as to how much it'll hold, it all depends on your file size. Your average movie can be hundreds of megs to 2-4 gig each....and the file size determines how much your device can hold.
I would say, since memory isn't upgradable, buy the biggest you can afford. I have a 16 gig and I get by. I have 2 albums, 4 movies, hundreds of documents and a couple dozen apps and I have 1-2 gig free. On the other hand, i have a 32 gig iPod Touch and it has a lot more music and videos on it and I just recently filled it up to having a couple of gig free.
If you're going to use your device for documents and surfing, go for th 16. But if you plan on movies and music, go for the 32. better to have to work to fill 32 gig than to have to constantly manage content to make the most of your room.

I haven't done an update since 24.0 because my computer is running out of memory. How much MORE memory will I need to get up to version 28.0?

I haven't done an update since 24.0 because my computer is running out of memory. How much MORE memory will I need to get up to version 28.0?
My computer is really old.
It is running out of memory.
I haven't done a firefox update since 24.0 because I think it will explode my computer.
I see that v28.0 takes 200MB.
How much more is this than what is already loaded for my v24.0?
Will it just add the extra pieces, or will it require a free block of 200MB (which my computer does not have)?
I don't want to crash and lockup my computer because I try to install something that is too big for the remaining memory.
Thanks.

You should updated to Firefox 28, Firefox updates don't take any new space they just replace the existing files.
There are some things you can do to clean up your hard drive to free up space however, http://arstechnica.com/civis/viewtopic.php?p=21178060 and http://support.microsoft.com/kb/956324, also uninstall programs you don't use anymore and delete files you don't need anymore.
You should also start saving up for a new machine, Windows XP is being dropped from support by Microsoft in a few days, which means it will no longer be safe to use on the internet.

How much external memory is necessary for a IMac desktop that has 4GB? I have a 500gb external hard drive and the computer is saying it is full.

My Imac has been recalled by Apple to replace the Seagte 1TB hard drive. I was told to back up my computer and I have a 500gb external hard drive. The computers memory is 4gb. why is my 500 gb external hard drive not enough space?

Your backup drive has half the capacity of the internal drive. Depending on how much of the iMac's drive is full, the external drive may or may not be sufficient.
It is like trying to pour the contents of a gallon milk carton into a half gallon pitcher. You may be able to pour the entire contents into the pitcher - but not if the milk carton is more than half full.

I have an iMac OS X Version 10.5.8 but I also have a MacBookPro 10.7.5 version, why software updates are not the same? For example, when I want to know how much memory can not store in the same way in either computer.

I have an iMac OS X Version 10.5.8 but I also have a MacBookPro 10.7.5 version, why software updates are not the same? For example, the way to see how much memory I have in my iMac is diferent than MacBookPro. And where I can see the memory of the disc I've got in my iMac? Than you very much.

If you want everything the same on both computers you need to be running the same OS X version. You can't because your iMac is a PPC machine, not Intel.
But to see information about your hard drive is the same for both. Simply select the drive icon on the Desktop. Press COMMAND-I to open the Get Info window. Disk information is in the upper panel.

I have IMac OSX 10.9.4, 4GB,Processor 3.06 with Intell2Duo. I would like to check for Malware. I run a TechTool Pro 6 every month and that comes up great.
When check how much memory I am using, with only Safari open I am using 3.9 and more of her 4.0 memory. She is very. very slow in processing. I had 4000
trash to clean out and it took her over an hour to expel. Also for some reason Safari will not allow me to click on a link, in my G-mail, and let it go to the page.
It has a sign saying a pop-up blocker is on and will not let me do it. I must open the stamp to look at my e-mails and if I have redirected link now I can do it.
I have not changed my preferences so where is this pop-up blocker?
I have looked at preferences on Safari and Google, which I do not understand Google, and do not see where this blocker could be.
Malware is something I want to make sure is not on my computer. Tech Tool Pro 6 is all I know of and it does not detect Malware.
Help.

I want to update my Mac from 10.6.8 to Mavericks, but every time it says update unavailable for this computer. How do I check for space available or how much space I have used? Help please, I am new to using Mac computers.

I am a new Mac user and I bought a refrubished Mac that has Mac OS X VERSION 10.6.8. I have been wanting to upgrade to Mavericks, but every time I go to do that a message comes up saying OS X Mavericks cannot be installed on this computer. Is there anyway I can instal it? Better yet how can I look up how much GB of memory I have and the available storage?

1. No, but you might be able to upgrade to Lion. Choose About this Mac from the Apple menu, check that the computer has at least a Core 2 Duo(not Core Duo) CPU, and if so, click here.
2. Check the RAM from the About this Mac window, choose Computer from the Finder's Go menu, control-click the internal drive, and choose Get Info. If the computer has a 32-bit EFI, it can't be upgraded to Mountain Lion or above regardless of the RAM and free drive space.

How much memory can I put in?

Mine is a 24", Early 2008 2.8 GHz Intel Core 2 Duo 4 B 800 MHz DDR2 SDRAM for memory, how much can it handle? w/Yosemite 10.10 & 2 2G right now.

Add a 4GB chip.
The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I now have 6GB installed on a machine supposedly limited to 4 GB.
