    1. The computer came with two X 256Mb RAM in slots 0 and 1I have bought one X 512Mb, placed it in slot 0 and moved 256Mb to slot 3. Setup shows Slot 0 and Slot 3 installed, Slots 1 and 3 uninstalled. I moved card in slot 1 to slot 4, but same result. Does this computer require memory to be upgraded with 2 X matched RAM cards?

    2. Compaq Presario SR1460AN

    3. 512Mb - Slot 0
      256Mb - Slot 2
      256Mb - Slot3

    4. Product Number - PW583AA - ABG

    Maybe take a look in the bios and try to determine whether the 3rd slot is single or dual channel mode enabled. If there are chips on both sides of the stick, it wants to be dual channel mode enabled. Try and get a motherboard monitor program to let you know a bit more about your memory banks.
    Also, download memtest and do a diagnosis.

    Could you please give some more information please?



    The exact model number of your computer, especially.



    List the slot labels of each module. (For example 256MB-Slot A1, etc.)



    Model of motherboard may help too. Thanks.

OK, according to Crucial.com your RAM does need to be installed in matched pairs.

Here is a link for your computer information:

If you get another 512MB module and install both pair, it should work well.

    Since your original RAM was installed in slots 0 and 1, you can replace them as they were and install the new ones in 2 and 3. Or you can, of course, put the 512MB pair in 0 and 1 and the originals in 2 and 3.

IBM T23 wont turn on after adding new RAM


Hi - according to memory suppliers your T23 has the following memory capacity / requirements:

  • IBM ThinkPad T23 maximum RAM capacity: 1GB
  • Your IBM has Two (2) memory slots or sockets
  • Module upgrade PIN count is: 144-PIN
  • The memory speed is: SDRAM 133MHz, PC133
  • The laptop DIMM type for the ThinkPad T23 is: SODIMM, SO-DIMM, Small Outline DIMM
  • Non ECC

If you are meeting these requirements, you may have a defective module.

Also, according to Lenovo's page on the machine:

Memory
The system has 128MB or 256MB of memory standard and can be configured for up to 1GB of addressable memory. Memory options up to 512MB SDRAM SO DIMMs each can be added in the two available slots for memory expansion. The standard 128MB of memory is expandable up to 640MB and the 256MB of memory is expandable up to 768 MB of addressable memory with 64, 128, 256, or 512MB SO DIMMs without removing the 128MB SO DIMM that is standard in one of the internal slots for memory. For customers that need the maximum 1GB to which memory can be expanded, it is necessary to replace the 128MB or 256MB card with a 512MB card plus add another 512MB card in the extra slot. Only 133MHz DIMM memory can be used in this system. The use of 100MHz DIMM memory is not supported in the T23 systems.

This means yo can trouble shoot the 512MB modules individually by installing one of the original 128MB modules and one of the new 512MB modules (for a total system memory of 640MB). If it does not boot, try again with the other 512MB module. This will help you identify a defective module that may be preventing the machine from booting.

I hope this helps & good luck!

I have a dell dimension 4600. It has original memory cards installed. 2 256 MB for a total of 512 ram. I recently tried to install 1 GB memory card. When I start up computer it beeps several times,...


hello

several beeps in a system is caused by a memory issue -- If you've recently added or tried to add additional memory to the computer and have started getting these beeps. Remove all new memory you've added to the computer. If the computer works fine after removing the new memory you're encountering either an incompatibility or defective new memory.

Sometimes when the computer is moved and/or over time a memory stick can become loose causing the computer to be unable to read the memory or get errors as it's reading it. Try fixing this issue by opening the computer removing each of the memory sticks you have in the computer and then placing them back into the computer.

If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer.

If you have more than one stick of memory try removing all but one stick of memory and boot the computer. If this does not resolve the issue try removing that stick of memory and try one of the other sticks of memory.

the specs can be found at this link
http://support.dell.com/support/edocs/systems/dim4600/en/4600i/sm/specs.htm

the system you have is upgradable to 4G of RAM, and this RAM must be installed in equal pairs
so if you have 4 slots to insert memory in (assuming you will retain the 2 256M) , you must install the other slots by 2 512M, 2 1G or 2 2G DIMMs -- make sure you isntall exact same DIMMs, dont mix memory makers or specs, other than what Dell specifies

memory type must be
PC2700 (333-MHz) or PC3200 (400-MHz) DDR SDRAM
(non-ECC)

i hope this helps --

getting compatibility is little difficult...
some times no combinations can work...

RAM is reading at 192, should be 256 as per original specs.


The portion of the ram you don't see is being allocated to the video card. That is typical in computers to share the ram between regular use and the video card itself. 64 is being shared. Sometimes in the bios you can change the shared about but sometimes you cant.

Change ram from 512 to 1 gig bios cannot read added ram


The original 2 sticks of 256 Mb of RAM gives you a total of 512
Mb of RAM. Two 512 Mb of RAM gives you a total of 1 Gb of RAM.
With two sticks of 512 Mb of RAM are you sure you got a total of 192 Mb of RAM, this is a lot less than the original RAM total of 512 Mb?
Should this be 1920 Mb of RAM?
If this 192 Mb is correct then the RAM modules are either not compatible with the laptop or if the RAM modules are not from the same manufacturer then they may not work together.

Most laptops have video cards that use part of the main RAM for video RAM, that is why the available RAM is less than the installed RAM modules. The amount of RAM the video card grabs depends upon the type of video card and in some cases the amount of video RAM can controlled in the BIOS setting.

I have a dell dimention with 256 mb ram i added a second card and now the computer will not start even when i take the new card out.


Did the card install smoothly? Take a flashlight and observe the memory slot for any damage. Also does the computer show any life at all? If so then try to get to safe mode or something of that matter. Right as you power up the computer press F8 a few times. Should bring you to a screen for you to enter safe mode. Also not sure with your computer, but pressing delete key at the very begin of startup should bring you to bios. From there you can see if you memory is at its original 256mb. Hope this helps :)

I added a 256 mb ram on top of my original 256 mb ram to make it 512 mb on my ASUS A6500R. how come when i check my system properties it show 384 mb? what's the maximum expandable ram for my laptop?


Check you system information on the net, it should say "it support up to ??gb. Make sure that the memory that you bought isn't it a high density memory, if it is it will only recognize half of the RAM.

Want more ram


Check if your new RAM is properly inserted. Also, see if the speed matches the other, original one. You might be mixing speeds that gives you some trouble. Another way is to swap the RAM, place the new one to the slot of the old one. Also, check if your motherboard will allow more memory to be added in your system. You may have reached the maximum memory capacity.

there is a hardware compatibility list for all pc, chances are your pc have exceeded its maximum allowance for any upgrade, even though you have installed a higher value or capacity of RAM.

Sdram capacity


its that 512 mb total capacity for your computer memory?? if so read this:
To find the total amount of RAM that can be added , subtract the amount of RAM currently in the computer from the maximum amount of memory the computer can hold. For example, a computer has 256 MB of RAM. If the maximum amount of memory the computer can hold is 512 MB, then 256 MB is the amount of RAM that can be added. this info from the HP website , to find out more , go to http://www.hp.com/support , enter the model number , and look for more information about your computer specs, hope this helps , please rate & thanks AJ
