2.5" Format 9.5mm High HHD Module; Bus Mastering; Ultra DMA ATA-100/133 Supprt on the memory it says it can take 200-pin SODIMM 512mb and 1GB 333Mhz speed or 400Mhz speed it has 2 256MB chips in it now and a 40gb hard drive looking to get a 100gb or 80gb hard drive maybe but don't know which one to get and looking to get 1gb of ram a 1gb stick

unfortunately laptops are not as easy to upgrade as desktops. the only thing you can do is buy an external drives and connect it via usb. memory is not upgradeable \n\nlaptops are made not to be upgradable as the desktops are designed for that

You need to leave more information.  What computer do you have, what motherboard....\n\nHow many slots in total do you have?\n\nIf you have 4 slots, then the chances are you need to insert 2 RAM modules at the same time.  Not a definite, as will need more info on your computer,  but thats probably likely. You could buy 2 sticks on 1GB, and insert them into the currently filled slots, and put the 2 512Mb in the other slots (if you have 4 slots)  That way you will have 3Gb RAM, should run quite will with that!!!

go to your computers manufactures web site and do some research they will tell you what speed you need and how much you can install. with ram the more is allways better!!

Your instinct is right:  it has both dedicated memory and shared memory (ATI calls it "HyperMemory").  You can have up to 256M of dedicated memory, and up to 128M more of shared.  It's actually a nice feature, since you can tune how much shared memory to use depending on what you're doing (and if you hate shared memory on principle you can just leave it off).\n\nThe second link below is about the 200M for Intel-based systems.  It looks like that version doesn't have shared memory, just dedicated.

No motherboard supports 40 Gigs of RAM. Not even servers with perhaps the exception of the World Enviroment Simulator in Japan.\n\nMost don't support more then 4 gigs because it's not feasible. 2 gig RAM chips are hard as hell to find and very expensive ($502 on newegg), therefore putting RAM slots that can read 2 gig chips is a cost that doesn't make any sense and has virtually no market appeal. Hence why the highest is 4 ram slots that can read 1 gig chips apiece for 4 gigs of total ram. \n\nThere are motherboards that can support more but they are very difficult to find and very expensive.

You can add/replace larger capacity sticks up to the total capacity that the computer will handle,.i.e.three 128MB sticks=384MB,three 256 sticks=768MB,one 512MB and two 256MB sticks=1024MB,etc.

your problem is not the ammount of memory your pc can handle but the type it can use, see computer memories have different names and numbers those mean the type of memory that it is and the ammount of Hertz that the speciffic stick is rated at. The best thing to do is to get the same kind of memory stick that you were previously using and make it 2Gigs or 3 that way, dont worry, nothing is broken, it is just a symple mistake.

The memory modules could be defective.  Try using memtest86 (link below).  Download the Bootable memtest86 CDrom then restart with cd in the drive and bios set to first try to boot from CDrom.\n\nLet it run for a while (go off and do something else) Watching it is boring.....  You should be able to see if there were any failed tests in which case the memeory is bad.\n\n**EDIT** I like to test one memory module at a time.  So, it is easier to determine which one may be causing the problem.  Sounds like one of the 128mb chips might be bad.\n\n**EDITx2** I doubt it is a frequency issue, If you install say 133MHz chip into a motherboard that uses max 100MHz the chips will be forced to run at 100MHz (just not thier full potential)  if you install a 133MHz chip into a 133MHz motherboard, then add a 100MHz chip they will be forced to run at 100MHz (the slowest one)  This is how it used to work on my older SDRAM motherboards, which i assume is what you are using now.\n\nIf the computer is booting up and going into windows but then it sounds like you are getting errors such as BLUESCREEN OF DEATH  0x039d733a  (something like that) it is most likely a faulty memory stick, where a portion of it is having READ/WRITE issues and windows is trying to use that bad portion getting errors and crashing.  If there were compatibilty issues I do not think the computer would pass the POST test (Power On Self Test)

I would recommend going to http://www.crucial.com/index.asp and using their memory finder if you ever have another question like this.  They also have an auto detect memory feature (see sources) if you don't know the model number or it's a custom built computer.  Once you know, then buy it cheaper somewhere else like newegg.  Give a man a fish and all that...

Oh I just saw that it has 2 GIG of RAM....okay, I take back my last comment. I think thats a great entertainment system for a great price. I think you should definitely get it. If you have any more technical questions about your system, then you can contact me, but for what I can see from the spec.....I think thats a great deal and I'm even thinking about getting it lol

easy...\n\ngo to kingston.com and use their ram wizard...  No guess work.\n\nAnoosh's suggestion just uses the system info in the registry.  It can be inaccurate.

Agreed..... check out the crucial web site and find out exactly what kind of RAM your computer will support.  But even if it says you can use the two sticks you already have, you could have some other compatibility issues.\n\nThe 512MB may be 333MHz instead of 266Mhz like the 256 stick.  Even if you could run them together, the different frequencies could be a problem.  Your computer might run at the slower frequency (if, in fact, the 512 has a different frequency, is  it also backwards compatibile.  Meaning, will it actually work at a slower frequency.)\n\nThe second issue is whether or not your computer will accept two different RAMs or do they have to be the same (in pairs.)  If the computer will accept different RAMs, make sure to check if they need to be installed in any particular order.  Some computers require that the largest stick be placed in slot # 1, the next largest in slot # 2, etc.\n\nAnd finally,find out if your new computer's warranty will remain in effect if you choose to deviate from the manufacturer's specs.  Nothing worse than spending big bucks on a computer, violating specs, needing repairs, and spending more on the repairs than you did on the whole computer because you trashed your warranty trying to save a few bucks.

Go to HP.com.On their support page you should be able to find the manual or a specs page. They will be listed by system model # or the model # of the motherboard. In either case it will give you the maximum amount of memory the system will take per memory slot. Also the memory speed. Be sure to pull the power plug before you change any internal component, especially memory. Good luck.

I followed the link below.\nHe claims that it uses PC100, it's relatively old RAM.\n\nCrucial says that they recommend PC133 RAM, and don't worry that it's faster. It'll slow down to the proper speed.\n\nRAM can slow down but it's very difficult to speed up.

ya if its the amount of space you need for the hard drive  i think that you should upgrade the memory to 512 and take a 2 or 3 year warantey gatway has ok service but dell is better try them as well !

I am buying now a "custom built" one with these specs\n-LGA MB\n-3.0 GB dual\n-4 GB 600 bus ram\n-250 GB x 2 HDD\n-256 SVGA Express\n\nand it costs me 1800$

Each memory slot can hold DDR PC2700 with a maximum of 512MB per slot.\n\nhttp://www.crucial.com/store/listparts.aspx?model=VAIO+VGN%2DFS690+Series
