Power down your machine if on unplug power cable. Then open case how ever it opens. Locate the dimm (memory) slots. There will be two ears that hold them in. Make sure both are open -outward from the memory modules. The memory only goes in one way look on the bottom of the memory and see the slot (grooves) in the bottom.
Now look at the motherboard memory slots they will have a bump in the middle of the channel. Match up the groove and the bump and place the memory in the slot. If done correct the only thing left to do is press down on the memory to lock the ears back down. Press down on one side thil the ear locks down, then press the other side down til it locks. The memory should be held tight by the ears if not open the ears and try again. It may take some force to lock into place but not to much. If it takes to much look and make sure you have the memeory in the right way. Close the case and plug everything back in.
Start the system and the bios should and the new ram up if it's an old system. Or if it's ne probably just tell you how much is in it and boot. Make sure to get the right kind of ram for your motherboard. Sorry for making this long but I don't know how much you know about computer hardware. Just wanted to cover everything. Hope this helps.

My pc wont boot up, led's 3&4 flash, I have renewed the RAM and the fault is still there, does anyone have a clue what the problem is?


Allan Cairnduff,
Below is the information for the 3,4 diag error.
Memory modules are detected, but a memory failure has occurred.
  • If two or more memory modules are installed, remove the modules (see your service manual), then reinstall one module (see your service manual and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error.
  • If available, install working memory of the same type into your computer.
  • The memory specs for this computer are listed below.
  • Type DDR3 Synch DRAM Non-ECC Memory Memory Speed 1333MHz Memory Connectors Four (MT, DT, SFF), Two (USFF) Memory capacities Up to 4GB Minimum Memory 1GB Maximum Memory 16GB(with 1333MHz speed memory)/8GB for uSFF only Memory

    The OptiPlex 790 system supports up to 16 GB of memory in the mini-tower (MT), desktop (DT), and small form factor (SFF) chassis with 64-bit operating system. The maximum memory supported in the ultra-small form factor (USFF) is 8GB. The memory speed supported is 1333MHz DDR3 memory.
    However, 32-bit operating systems can only use maximum 4GB memory address space. Certain components within the computer require address space in the 4GB range, any address space reserved for these components cannot be used by computer memory the amount of memory available to the operating system is less than 4GB.
    NOTE:
    Memory modules should be installed in pairs of matched memory size, speed, and technology. If the memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.
    NOTE:
    The total amount of available memory will be less than 4GB. The amount less depends on the actual system configuration. To fully utilize 4GB or more of memory requires a 64-bit enabled processor and 64-bit operating system Thank You,

Hi,
Looks like Memory Issue,
Memory modules are detected, but a memory power failure has occurred.
You can try as follows :
  • If two or more memory modules are installed, remove the modules, then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error. If only one memory module is installed, try moving it to a different DIMM connector and restart the computer.
  • If available, install verified working memory of the same type into your computer.
Let me know
Thanks

I bought P3200 ddr 400 1gb memory and when i install it , it does not show up. any ideas why and if there is something i can do .


The Intel® Server Board S875WP1-E supports both ECC and Non ECC Unbuffered PC2100 (266 MHz), PC2700 (333 MHz), or PC3200 (400 MHz) compliant Double Data Rate (DDR) memory modules. Dual channel memory functionality requires two DIMM modules installed into DIMM sockets 1A & 1B, and then DIMM sockets 2A & 2B. The DIMM module size, speed and vendor must be the same.

You can install a single 128 MB memory module into DIMM socket 1A. The minimum supported memory size is 128 MB. The minimum main memory configuration is a single 128 MB memory module, and the maximum configurable memory size is 4GB. With only a single memory module installed, the system will only operate using a one memory channel.

Third party memory vendors may use the same module part number with different
DRAM vendors and die revisions. To insure proper system operation, verify that each DRAM
vendor and die revision has been separately tested and qualified. Please notify CMTL if there is a discrepancy.

eMachines T3642 Computer takes the PC2-5300 DDR2 SDRAM DIMMs. Supports Dual Channel DDR2. Memory Type, and comes installed with 1.0 GB = 512 MB (removable) + 512 MB (removable) of Memory. You can upgrade your eMachines eMachines T3642 Computer to up to a maximum of 2.0 GB Memory, the system has 2 sockets to install Memory, already with 1.0 GB = 512 MB (removable) + 512 MB (removable) standard Memory installed. For best Computer performance use the maximum amount of allowed Memory per slot for your Computer.


INSTALLATION PROCEDURE
1. Place the computer power switch in the "off " position and disconnect the AC power cord.
2. Remove the computer top cover following the instructions in the model-specific owner manual.
3. Before touching any electronic components, make sure you first touch an unpainted, grounded metal object to discharge any static electricity stored on your clothing or body.
4. Locate the memory expansion sockets on the computer motherboard. If all the sockets are full, remove smaller capacity modules to allow room for higher capacity modules.
5. The ejector tabs shown in the illustration are used to remove a module. By pushing outward on the ejector tabs, the module will pop-up from the socket and it can then be removed.
6. Handle your new module carefully; do not flex or bend the module. Always grasp the module by its edges.
7. For most installations, DDR modules can be installed in any available expansion slot. Other installations may require the memory to be installed in a particular sequence based on the modules capacity. Check your owner manual to determine the correct installation sequence for your configuration.
  • Insert the module into an available expansion socket. Note how the module is keyed to the socket. This ensures the module can be plugged into the socket one way only. Firmly press the module into position, making certain the module is completely seated in the socket. The ejector tabs at each end of the socket will automatically snap into the locked position. Repeat this procedure for any additional modules you are installing. install_ddr.gif 8. Once the module or modules have been installed, the computer top cover can be reinstalled.
    9. Plug in the AC power cord and reinstall any cables disconnected during the installation process.
    10. Turn on the computer and follow the instructions in your computer owner manual that describe the steps necessary to allow your computer to recognize the newly installed memory.

    My Dell Optiplex GX520 will not boot. There is no video output and the 3 and 4 diagnostic lights remain on.


    If 1 & 2 are off ... then you have problems.

    Memory modules are detected, but a memory failure has occurred.
    • If you have one memory module installed, reinstall it and restart the computer. (see Memory for instructions on how to remove and install memory modules.)
    • If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
    • If available, install properly working memory of the same type into your computer.
    • If the problem persists, contact Dell (see Contacting Dell).

    Ram upgrade


    Step 5: Remove a memory or continuity module Continuity modules do not contain memory, but are placeholders to close the memory circuit. Use the following steps to remove a memory or continuity module:
    1. Pull out, and then press down on the holding clips that retain the memory modules. The memory modules should rise up slightly out the socket. Figure 5: Opening memory module tabs c00571682.gif
    2. Pull out the memory or continuity module (for RIMMs) and place it in a static-safe container.
    Step 6: Add a memory module Use the following steps to insert a memory module into an empty socket:
    1. If RIMMs are being used, keep the following items in mind when purchasing and installing modules:
      • The memory configuration of channel A (the first two sockets) and channel B (the second two sockets) must be identical.
      • Continuity RIMMs must fill any open memory sockets.
      • When a continuity RIMM is required, it should be installed into the second socket.
    2. Align the memory module so the small notches on the lower edge line up with the raised marks in the socket. Figure 6: Memory module installation c00571683.gif 1 - DIMM (notches farther apart) 2 - RIMM (notches close together)
