why does my cp still registers only 64 mb although i already changed my sdramm to 512mb?

Do you have the original 64mb still in the computer, and you just added a 512mb card? If so, your BIOS might not recognize the additional memory; you'll have to do research to determine if this is the case.\n\nIf you swapped the cards, though, you might have a bigger problem: older computers often had limits to the amount of memory they could use, and even though sdram is now available in multi-GB amounts, your computer's bios may only allow a maximum of 64mb of it to be used.\n\nYour best bet here is to (a) make sure you've purchased compatible memory, (b) swap the cards instead of installing both (if you haven't already), and (c) check the manufacturer's site to see what the maximum memory amount recognized by the system is.

Look up your system model on the support section of the manufacturer's page.  There will be a lot of technical jargon in the RAM section that you will probably not understand.  Copy it down and take it to a store that sells computer accessories (Best Buy, Circuit City, CompUSA, etc) and show it to the salesman.  If you want really good performance, tell him you want low-latency RAM instead of the budget high density crap.  Until then, increase the size of your paging file and hope for the best.  You can also disable unnecessary startup entries and background services.  Many people will tell you to use msconfig by going to Start - Run, typing "msconfig" then go to startup tab, this is not quite accurate.  To accurately disable the startup you should disable it from within the settings of the program itself.  This is to be sure that the registry entry is not recreated on the next reboot.  To disable background services that you don't need, go to Start - Run and type services.msc.  Disabling unnecessary services here will free up a lot of resources - probably more than anything else you could do to the system minus upgrade.  Also, you should optimize your caches.  If you can perform these tweaks effectively, you may not even need a RAM upgrade, but it's still recommended if you have less than 512MB RAM in XP.

It sounds as if you need more Memory=RAM which you didn't mention how much the machine has..\ngo to http://www.crucial.com put the name and model number in the search place and they will show you the excat amount  and kind  the pc uses

Maybee you added too many extensions to it! 128 Mb is required for the standard Fifrefox, the one from the install! The more themes and extensions you add to it the memory is required!

Can't answer the first question.\n\nThe native state of computer memory is null. That is not the same as blank or zero; it's nothing.

1st do you know the type of RAM you need for your system?? DDR. SD and its speed? 2nd do you if you have an empty slot on your motherboard? if you have the right RAM and an empty slot,unscrew the ram cover and install the DIMM>

All processors have a limited memory space, this limit is defined by the number of "lines" or bits that are used to define a memory address.  In the simplist example, say you have a 32bit processor that has a 32bit memory space, that means that the processor can access a theoretical 2^32 number of unique memory address (4GB).\n\nWhat you can't do is to assume that a 32bit processor has a 32bit address space (or a 64bit processor has a 64bit address space).  They are two different things, that while are often times equal (it makes doing pointer manipulation a lot easier since an address will fit perfectly into a register) aren't necessarily so.  An example would be the 80286 processor that had 16 bit registers but had a 24bit address space.\n\nThe limitations of a 32bit app in a 64bit environment depend entirely on exactly which 64bit environment you are referring to.  The generic answer is that the 32bit app might not have access to the full 64bit register nor the full address space.  However, it's not uncommon for processors to support mixed modes (e.g. allowing 32bit apps to take advantage of 64bit registers and addressing if the 32bit app is aware that it is running in a 64bit environment).  You can also play games with the memory controller to allow 32bit apps access to >32bit addressing.

This problem is all too often a memory problem. check that your memory sticks are properly seated.

not necssary , but u have to add multiple capacities , means , another 1 GB , or 512*3 , u cant add 256 to 1 GB

Memory is HARDWARE, not software.  \n\nAll you have to do is buy the right kind of memory and stick it in.   A caveman could do it. \n\n(no offense)

Did you really expect to notice an increase in speed when upgrading from 512MB to 1GB ? Answer is: you don't.\n\nOpen the Task Manager and look how much of the memory is still available.\n\nI have also an installed amount of 1GB and mostly there is 50% unused.

I assume you've updated all fixes and patches, and are still getting either a divide by zero or insufficient memory error.\n\nHave you tried rightclicking the icon and tinkering with the compatability settings. Sometimes that does the trick.

I think you are using one of window operating system. In windows virtual memory automatically assigns as much as the amount of RAM you are having. If you increase RAM, the virtual memory will also be automatically increased. If you want to change the virtual memory manually do thse steps\n\n1. Open 'Control Panel'\n\n2. Double click on 'System Properties'\n\n3. Click on 'Advanced' tab\n\n4. Click on 'Settings' button in 'Performance' frame\n\nNext steps may be different according to the OS you are using. I am using Windows XP Service Pack 2. If it is different from your machine, you can explore from this point and find it.\n\n5. Click on 'Advanced' tab from the 'Performance Options' window\n\n6. Here you can see the total page file size of virtual memory, Click on 'Change' button near to it.\n\n7. Change the initial and maximum size of virtual memory you needed

Maybe you need to install more RAM or increase the Virtual Memory. Read this about RAM Booster. http://forums.pcworld.co.nz/showthread.php?t=14202

first of all your the virtual memory is in reference to the swap file that windows uses on your hard drive . there could be several causes for your dilemma .\nstep 1.  right click "my computer"\n\nsystem properties should pop up\nstep 2. click the performance tab\n\nyou should see a virtual memory button near (but not at) the bottom right.\nclick that button\n you should see two options, one is two let windows manage virtual memory, and one to specify the amount of memeory, I highly recommend that you let windows manage memeory if you dont, because if you let windows manage it , windows will do whatever it takes to Make more memory available in the swap file.  if you already have windows managing it then something else is wrong\neither one of two things\n1. you do not have enough space on your hard drive . in this case you need delete unecessary files and programs, in general you should always make sure that free hardrive space does not go below 10%, 15 % just to be safe.\n\n2. your swap file could be corrupted. in this case your going to have to delete the current swap file, but you cannnot do it within windows. so you have to shut down and start up in pure dos.\n\nwhen you start up in dos Type in (without quotes") "chdir C://windows"  you may even already in this directory if so then go to the next step type(without quotes) " del win386.swp".\n then restart your system . windows will create another win386.swp swapfile upon start up , so expect a longer than usual start up . if you really dont know your way in dos or if the instructions arent clear enough. just e-mail me at Fuzzyclutter @yahoo.com i will try and clarify.

Hi. You should set your virtual memory to 1 1/2 times your actual memory. If you have 128MB memory, you should set virtual memory to 192MB. On Win XP, you should right-click on My computer, go to Properties, go to Advanced, select Settings under Performance, click the Advanced tab, then Change button at bottom of this screen. Select Custom Size, and put 192 in the initial AND max sizes. This will probably cause your system to have to reboot. \nCheers.
