I have a gateway2000.  I had 2 64 mb memory sticks for a total of 128 mb.  I took one of the 64 sticks out and installed a 128 mb stick.  Now, it is showing that Ihave only 96 mb of extended ram and 512 ram of cache memory.  Where is the rest of the memory?

You might want to go here Protonic (see link below)\n\nThey would help you, is free also.

You get single sided and double sided memory modules. there is the possibility that your motherboard cannot take double sided memory (single sided is more generic). if the memory module has little chips on both sides of the module, then it's double sided. you should install each memory module you have, one at a time, on it's own to check that your computer can 'see' it.   \nAlso, install one module that works into both slots on the motherboard to check that both slots are working. check your bios settings for ram speed, set to 100 not 133

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.

Check your computer's specifications...usually found online someplace if you look up the model number and make.  Sometimes it'll tell you what the maximum memory is for your computer.  It doesn't matter what sizes you put in there to make up the numbers as long as (I'm thinking) it's within your max memory.  I seen some older computers only a max of 128RAM....was time to ditch those badboys.  I'm running 512mb right now...two 256 sticks.  Computer runs great even doing videos while running other programs.

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.

The difference in memory installed is probably being used by your video card.  It looks like around 22MBytes.

First, download a program called "Belarc Advisor".  It will analyze your computer quickly and give you a report of all the hardware and software installed, and it's free.  In the report, there will be a section called "Memory Modules" that describes your existing memory.  It will also tell you what kind of motherboard you have.  \n\nNext, go to the website mwave.com.  You can find the memory you need there at a great price, and if you still don't know what you need, just call them up and give them the information from Belarc Advisor and they'll help you out.  I've had excellent service consistently from this company since about 1998.\n\nWhen your memory arrives, turn your computer off and look for a slot that has the same size and shape of circuit board as your new memory.  Install your new memory next to it.  Make sure the tabs click fully into place so you'll know it's seated all the way.\n\nThat's it!\n\nDO NOT buy your memory from a retail store like Best Buy or Staples.  They will charge you well over double what you'll pay almost anywhere online.  Also, don't pay anybody more than $45 to install it, it's a super simple task and no tech has any business charging more than the minimum hourly rate for it.

easy,juz plug in the RAM n turn on ur pc...mostly it'll function coz RAM size doesn't metter, but the speed does...u juz mention bout 256MB n 512MB of DDR RAM but wat's it's clock speed...coz some of 266 mainboard cannot support DDR400...\n\noh ya...and some times the brand of the RAM will effect the result...\n\nanyway...theories doen't gv result...so the easier way is to test it practically...\nEXP: some time Kingston RAM will Clash with Apeccer RAM...

Check the BIOS, maybe 128MB is used as Video RAM.  If that's the case, you are really OK.  But you might be looking at getting more RAM.   Visit http://www.coastmemory.com and look up your system. \n\nGood luck

go to bios(when your computer starts it shows a little info about yoour computer and it says to press del or other key to enter bios.press the key) and enable your RAM. A computer can not work without RAM !

Most likely, the RAM stick you removed has a lower speed rating or latency than the other one.  Try alternating them and see if you get more speed.  If so, replace the slow stick with one of the same latency.\n\nWhen you purchase the stick, try to find out the SPD timings and latency beforehand.  The lower the numbers, the faster the RAM.  This is a major performance factor.  Good luck.

Your RAM you need better RAM 248 is grabage.\n\nI reccomend this 2GB will greatly improve preofrmace speed.\nYou might not want to pay that much but look around.  MAKE SURE THE AMOUNT OF PINS ON MEMORY MATCH THE PIN SLOTS ON YOUR MOBO(motherboard).\n\nhttp://www.newegg.com/Product/Product.asp?Item=N82E16820150054

Speed and type of RAM used is dependent on the chipset used to make the mainboard. \n\nIn your case, the answer is "no way". DDR2 didn't exist back then except in a lab.

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

If your motherboard can handle the ram. Some motherboards have a limit and sometimes the only way is to change the mb.

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
