Question about Computers & Internet

2 Answers

I have two dell computers, dell dimension 4600, and dell optiplex gx270 smf. I've checked into upgrading the memory on the gx270. It says that it uses the same memory configuration as the dimension 4600. I tried to swap out some of the memory from the 4600 (2 512 mb ddr 3200 400mz) to the gx270 and it started beeping and would not boot up. Any suggestions would be appreciated.

    Sorry but I don't have info on motherboard and such. I bought the computer off of ebay and received no manuals or anything. I did one of those automatic checks from crucial and it said that pc3200 at 400mhz or pc2700 at 333mhz would work. Everything I've researched says it will hold 2gb memory (only has two slots).

    The computer I am trying to upgrade memory for is the gx270, which has only two dimm (1 and 2). Both crucial and kingston say that memory type and speed are the same for both computers. I was going the cheap route, trying to use some of my memory from my dimension 4600.

Even though the memory stick sizes are the same, and the speed, there are other differences between memory types, such as parity/non parity, 2x32, 16x4 etc. more than likely, the speed of the memory sticks are different. the easiest fix for this is put the slower memory sticks in bank0 and bank1 (logical numbering used) and then the faster memory sticks in bank3 and bank4. this will cause the faster memory sticks to run at the speed of the slower memory sticks. If your sticks are parity and non-parity mix, then you will probably not be able to combine them.

The beeping that you hear it's your motherboard telling you there's a problem, the beeping in esence is a code (like morse code but the same) so it has a meaning...

since it's memory what you changed this simply means 3 possible things:
1. (likely): the memory are probably not entirely compatible, check the motherboard documentation for each one of the motherboards to find out specifically which type of memory can be on a system, the capacity (512), the type (ddr), and the speed (3200/400mhz) is part of the compatibility issues, but find out about error correction type, front bus speed of the mother board, and the cas number.
2. (possible) some systems are picky with memory.. sometimes using different sets (from different companies) becomes an issue.
3. (rare but possible). did you handle the memory sticks with care? do you know what ESD is? and did you ground all the components accordingly to protect your system from ESD while working with this components and while working inside the computer.. if not you may have fried a component and you may not have even notice it... (risk when working with no equipment or when not taking preventive measurements)

to find out about the beeping code that you're getting check out this website:

    not having all the information may bring problems:

    this is for your dell 4600:

    The recommended memory configurations are:

    • Install a pair of matched memory modules in connectors DIMM1 and DIMM2.


    • Install a pair of matched memory modules in connectors DIMM1 and DIMM2 and another

    matched pair in connectors DIMM3 and DIMM4.

    • Do not install ECC memory modules.

    • If you install mixed pairs PC2700 (DDR 333-MHz) and PC3200 (DDR 400-MHz) memory,

    the modules function at the slowest speed installed.

    • Be sure to install a single memory module in DIMM 1 or the connector closest to the

    processor before you install modules in the other connectors.

    this is for dell optiplex gx270 smf

    4 DIMM slots (SF Chassis only has two); Non-ECC dual channel shared2 DDR SDRAM system memory

    (333Mhz or 400Mhz) up to 4GB on the SD and SMT chassis


    this is to keep in mind:

    If you remove your original memory modules from the computer during a memory upgrade,

    keep them separate from any new modules that you may have, even if you purchased the new modules

    from Dell. You should install your original memory modules in pairs either in connectors DIMM1 and

    DIMM2 or connectors DIMM3 and DIMM4. If possible, do not pair an original memory module with a new

    memory module. Otherwise, your computer may not function at optimal performance.


    you may not be pairing the memory modules correctly, the speed may not match or you have a memory-picky system.

    try to test the memory modules by using the ones from the gx270 in the dimension 4600... don't combine memory modules from the 2 systems.. if it works fine, you have a memory picky system.. if it doesn't work test one memory module at the time.

    have you tried to change the memory speed in bios? btw.. is bios able to see your memory modules??

    when testing install one memory module at the time, turn system on and test booting the system. it it works add another module and keep doing that way.. (install-test-install-test...)

I have a dell optiplex gx270, tried to upgrade my memory with samsung 1gb pc3200 ddr1 but doesnt work, just beeps on start up.

That is the correct memory module (Non-ECC).

Remove all memory modules.
Insert the one Samsung PC3200 module and start up.
If it doesn't boot, then try a different slot.
If it works ok, then add-in your original mamory modules. If they are PC2700, then they may not work together.

Dell optiplex gx270 serious error!

it might be due to your new hard drive, plz check the ram also

Frequent message - virtural memory is low, increasing memory

Many times upgrading the ram amount will correct this problem. You may also upgrade you Video card for one that has a lot more memory chips(Total Ram) on it, since you have a desk top type computer. I have included a link in case you have misplaced you manual to see the original specifications. Ram and Video cards are available on line for such places as :               or                to name two.
