i have checked the properties of My Computer, and it actually sows that the additional ram has been recognised by the computer, but i still can not feel the 512mb increase in ram. any solution?

RAM is such a tricky thing. Did u upgrade with a stick of RAM that is by the same manufactuer (also the same specs)?  If not then there can be some conflict between the 2.  Since u took it to the shop for them to install it, I assume u aren't comfortable with removing/installing the RAM yourself?  I ask because u could take out the old RAM and try running the computer with just the new RAM to see if u have the same symptoms.  An option to try w/o opening up your computer would be to run a small memory testing program from a CD that can tell u if your new memory is bad.  Go to http://www.memtest86.com/ dowload, unzip and burn to a CD

There are occasionas where RAM is dead when it's arrived.. maybe it got shorted.\n\nTry to insert it with just your new ram and take out the older one.  Anytime you are working on your computer, ground yourself first by touching a metal other than your computer and don't do it on carpet either.\n\nInsert your new ram without older one in it; see if your computer reads that.\nMake sure you are inserting the ram all the way and clicks okay but not forcefully.\nIt's a trial and error process but then again you could just return it and get a new one.\n\ngood luck

Hmm, if you've already lowered your graphics rendering thingy, reduced the fonts (like, in the on-screen messages), and changed the resolution on your games colors, i can't think of anything else.\nRAM is cheaper these days, so just buy more.  More computers these days have at least a Gig of RAM, it's the wave of the future!  Plus, games will just keep getting better and better, so eventually you'll need to keep up, so when's a better time to buy more RAM?\nGood luck

OOH, No stickers?!!?  There I dunno how you will.  Best way is to ask a computer dealer to try the RAM for you and give you the specs.\n\nOr better, try it at a friend's who's willing to help u out.

if you have a new computer, its going to be in increments of 128 megabytes.  You probably want 2 512 mb "sticks" of "DDR 3200" if you have a fairly modern computer.  Look up your motherboard and see what ram it can use...don't just buy some random stuff.

It'll take a lotta time to describe the whole process, so i've listed a couple of links here. Visit those links n read 'em.\nhttp://www.pcworld.com/howto/article/0,aid,18024,00.asp\nhttp://www.ehow.com/how_895_install-ram.html\nhttp://www.pcmech.com/show/memory/87/

A few things... 1) The chip may be defective 2)The mother board in your computer doesn't support 512MB sticks.\n\nDoes the system start up when the chip is installed? If it does you could use a program like MemtestX86+ to test each chip.   \nYou may also want to check compaq's website for any bios updates that may help the computer.  \n\nFinally, PNY's memory configurator is a nice help for figuring out what your system can handle.  It will give you details about the motherboard, like how much ram is supported, bus speeds, cpu speeds, etc... Granted they will recommend PNY memory products, but their product model numbers give away the specific type of memory they are e.g. PC100, PC133, etc..

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.

Unfortunately for all of us, RAM is not something you can increase like you can your processing speed.  You must install more RAM physically into your computer in order to meet this requirement.  If you can't afford more RAM, the best remedy i can think of is increasing your Virtual Memory (this is the memory that a computer uses from your hard drive to act LIKE RAM).\n\n*Virtual Memory is no where near affective as actual RAM.  It is not a good nor effective way to fix your problem, however, it may solve your problem temporarily if you simply/absolutely CANNOT afford more. (RAM is really cheap.  Go to www.tigerdirect.com)\n\nTo increase your Virtual Memory, Go to My Computer and right click somewhere inside that box *click properties*.  Go to the "Advanced" tab on the box that pops up.  Under the Performance section, click Settings.  Under that Settings box that pops up, go to the Advanced tab and look at the bottom section labeled "Virtual Memory", click Change.  Now you can add whatever amount of memory desired in order to increase your virtual memory.  Remember, this will NOT completely fix your problem, only lessen the effect of not having enough RAM.  Once you save up enough memory, I would recommend fixing all your problems by buying a single 1024mb (1gb) RAM chip (you won't have to worry about problems any more)

The RAM modules' speed must at least match the memory controller on the motherboard. You can always use faster RAM modules than required, but not slower.

The ram which I assume is what you are talking about, can be upgraded from 256 to 512 yes... You will need to find out what type of ram you need...\n\nto find out what ram you need use this http://www.crucial.com\n\nit will ask you for your make and model, then tell you what type of ram you need. It will also give you prices, but dont buy from them, just write down the type of ram, and search your local stores for it...\n\nIf you wish to buy it online, try http://www.tigerdirect.com or http://www.newegg.com

The memory you have is not sufficient if you have Win XP.\nIf you have integrated video on your computer and not a video card you have less than 200MB which is just sad. Memory is dirt cheap for 512MB do yourself a favor and get it.

you may have a virus on it or you could just need more RAM, take a look at the properties on 'my computer' and it will tell you the ram on the first tab that opens (you want a min of 512mb)

that's not really an upgrade, just a very slight incline grade (like about 1 degree from horizontal)\nget a single stick 256 or 512\nthe ram will not work faster than your system will allow it to

http://computer.howstuffworks.com/question175.htm\n\nUp to a point, adding RAM (random access memory) will normally cause your computer to feel faster on certain types of operations. RAM is important because of an operating system component called the virtual memory manager (VMM).\n\nWhen you run a program such as a word processor or an Internet browser, the microprocessor in your computer pulls the executable file off the hard disk and loads it into RAM. In the case of a big program like Microsoft Word or Excel, the EXE consumes about 5 megabytes. The microprocessor also pulls in a number of shared DLLs (dynamic link libraries) -- shared pieces of code used by multiple applications. The DLLs might total 20 or 30 megabytes. Then the microprocessor loads in the data files you want to look at, which might total several megabytes if you are looking at several documents or browsing a page with a lot of graphics. So a normal application needs between 10 and 30 megabytes of RAM space to run. On my machine, at any given time I might have the following applications running:\n\n    * A word processor\n    * A spreadsheet\n    * A DOS prompt\n    * An e-mail program\n    * A drawing program\n    * Three or four browser windows\n    * A fax program\n    * A Telnet session \n\nBesides all of those applications, the operating system itself is taking up a good bit of space. Those programs together might need 100 to 150 megabytes of RAM, but my computer only has 64 megabytes of RAM installed.\n\nThe extra space is created by the virtual memory manager. The VMM looks at RAM and finds sections of RAM that are not currently needed. It puts these sections of RAM in a place called the swap file on the hard disk. For example, even though I have my e-mail program open, I haven't looked at e-mail in the last 45 minutes. So the VMM moves all of the bytes making up the e-mail program's EXE, DLLs and data out to the hard disk. That is called swapping out the program. The next time I click on the e-mail program, the VMM will swap in all of its bytes from the hard disk, and probably swap something else out in the process. Because the hard disk is slow relative to RAM, the act of swapping things in and out causes a noticeable delay.\n\nIf you have a very small amount of RAM (say, 16 megabytes), then the VMM is always swapping things in and out to get anything done. In that case, your computer feels like it is crawling. As you add more RAM, you get to a point where you only notice the swapping when you load a new program or change windows. If you were to put 256 megabytes of RAM in your computer, the VMM would have plenty of room and you would never see it swapping anything. That is as fast as things get. If you then added more RAM, it would have no effect.\n\nSome applications (things like Photoshop, many compilers, most film editing and animation packages) need tons of RAM to do their job. If you run them on a machine with too little RAM, they swap constantly and run very slowly. You can get a huge speed boost by adding enough RAM to eliminate the swapping. Programs like these may run 10 to 50 times faster once they have enough RAM! \n\n---x---\nupgrading memory is a cheaper option than buying a new pc

I am guessing here but the most likely answer is that you have an integrated graphics system (no separate graphics card) and the graphics system is keeping a portion of you total RAM for its own use and therefore it is not available to the rest of the system.\n\nPS: Buy some more RAM if you can afford it. 256 is only just enough nowadays.\n///
