Problem installing ram

Hello,
I am trying to install some ram into my thinkpad. I already have the 512 that came with the system, and it supposed handle up 2028 megs (or somewhere in that area).

The ram i bought is 1 GB 200pin DDR2 sodimm - which according to specs should be more than compatible with my system.

When I install the ram and turn on the computer, i hear a series of beeps (like 1-2-3 (pause) 1-2-3), then the screen stay blank and nothing happens from there, I remove the new ram and everything starts up fine. I have tried this multiple times, defragging before installing, disk cleanup, running virus/spyware scan etc... but to no avail.

Any suggestions?

Thanks.

Oh, I'm running windows XP home edition.

    OK, I read your reply and did some research using the link you provided as well as your knowledge.

    After doing some homework, I had a feeling that the possible bad memory slot you mentioned might have been the culprit. So I took the laptop apart, took out the factory 512 chip, and installed my 1 gig ram, put it back together and powered up and... she worked.

    So I just ordered a single 2 gig ram chip to replace the new 1 gig chip in the factory slot so I can get all the memory out of this thing that I can as I use it for lots of editing, photoshop/website design & music editing etc...

    I thank you for your help as I might have decided to take this for service. Instead, I found some good advice and the got nerve to take this machine apart, learn something new and save some money at the same time.

You have the wrong memory chip. The beep code you hear indicates that there is no memory or incompatible memory. The memory you need is PC4200, Which is a 533mhz chip. Memory has a frequency rating that is matched to the processor and motherboard. Not just any DDR 200 pin memory that fits will work, the frequency has to match or it won't work. The new chip should be labeled, make sure it reads PC4200 or 533mhz, if it reads anything else it's the wrong chip. If it is the right frequency chip, then you may have a bad memory slot, the chip is bad, or mislabeled. Here's a link to a memory configurator that gives the memory specs for your machine.

    You're welcome. You should also keep in mind that in some machines each individual slot will only hold a certain amount of memory, if your machine only shows 1g after installing the 2g chip then you will know why. I hope the 2g chip works out for you, if there's anything else feel free to ask, and don't forget to rate me (fixya). Thanks

RAM chip sets


It is OK to mix chip (SODIMM) capacities in the 2 slots in your notebook.

The best system performance will be when you have 2 x 512MB but for now if you install 1 x 512MB, you could even leave the old chip in the other slot, it'll be fine.

Hello Sir, I had 512 MB 533 MHz DDR2 RAM(Dynet). Now I have bought 1 GB 667 MHz DDR2 RAM(Dynet). My system has 2 slots. In one slot, I have 512 MB RAM and in another slot, I installed 1 GB RAM that I have...


The Intel D102GGC2 uses a Dual Channel Memory Architecture meaning that both slots need to be running at the same speeds. I would suggest getting another 667 MHz RAM card and installing it along side your current one, just as I reminder this motherboard only supports 2GB RAM Max so don't get one that is above 1GB.

Hello i can't install a AGP 512 videocart I bought


your computer needs more than the video card ram amount to use a particular video card. if you do not have at least 512mb of system ram, that may be your problem. if you have sufficient ram, then you do not have a powerful enough power supply for the new card.

What is the maxium upgrades that I can give my Thinkpad T20 Series 2647, from speed to memory and possible going from a Pentium 3 to a 4?


You can't upgrade the processor: it's already at almost maximum and you can't change models - different socket. The maximum RAM you can install in it is 512 MB of PC100 SODIMM-SDRAM so the speed difference will be negligible.

I would like to nwom how much of memory this laptop support


The Thinkpad is installed with 128 MB SDRAM is standard, and is expandable to 512 MB
There are two memory slots, to expand it to 512 Mb you need two 256 Mb RAM modules and throw away the 128 Mb RAM module, but if you don't throw away this module and you insert a 256 Mb RAM module in the 2nd memory slot then your total memory would be 384 Mb.

I am supposed to have 512 mb ram but my system shows 384 ram even when I am doing nothing why


Hello,

128MB of your RAM is dedicated to the video port. Low end pc share the installed rams to run video streams instead of having its own dedicated ram. No matter how much ram you install, the system will always deduct 128mb for video.

System won'n boot if i installed two RAMs


Hello,

Is the old ram working if installed alone? If yes then maybe got error or grounded if both ram inserted. Try to blow air the ram slot in the board to eliminate dirt and then try to interchange the position of the ram and then try it again.

Hope this will work.
