check to make sure you have added the right type of memory. also look at your user manual. it should tell you where and how to place the added sticks. sometimes they have to be added in pairs or have to be in specific slots. also if you dont have the manual it is on the gateway site. you should type in your model and serial number and get all the info you need.
1st try to exchange the cards in the slot.
2nd try another card
3rd ur RAM slot may not be ok
4th ur RAMs may not be compatible
5th ur new RAM card may not be ok
use same type of RAMs, and same size...
if u have 256, add 256
if u ahve 128 add 128
if u have SDR then dont add DDR
getting compatibility is little difficult...
some times no combinations can work...
note...technology keeps changing...so a old RAM card that was bought years ago may not be compatible with a new RAM card....
even i got all my old RAM cards(256+128) removed and got 2 - 512mb of the same type fixed...even i had issues with my RAMs for 6 months...
The memory might be correct, but the server may require matching RAM. Check your hardware specs for details, but you may need two matching modules in the correct banks for the server to recognize and utilize the RAM.
Windows xp will usually only see 3.5 gbs of ram even in your motherboard can support more. WIndowns vista does recognize more RAM or i also believe windows xp 64bit recognizes more ram. Nothing wrong with ram or your computer its just your operating system.
I had the same issue on this board where it came with a Samsung 512 MB 533 MHz PC2-4200 DDR2 DIMM. I put in a 1 GB Kingston with the same specs (533 MHz PC2-4200 DDR2) and it would not recongize the Samsung anymore with the system reading as 1 GB of RAM instead of 1.5 GB. Tried every configuration and would only see the Kingston. It would only see the Samsung if I pulled out the Kingston regarless of the slots I use. So, I just bought the exact same make/model of Kingston and it recognized that fine and the system now has 2 GB of memory (max this board allows). And, I had already installed the latest BIOS for this board from Intel before doing all this so wasn't an old BIOS. I'm figuring the board didn't like something about the Samsung memory (speed, module configuration, etc.) that made it not play nice with the Kingston. If interested I bought the DM8400A/1G Kingston modules. And, this board appears not to support dual channel memory. Only has channel A, slots 0 and 1, and I read need two channels to support dual channel (seems obvious). Boards that supports dual channel memory normally have 4 memory slots, two for channel A and two for channel B, then put in matching modules in slot 0 for channel A and B and have dual channel memory access. And if want more ram, then matching modules in slot 1 for channel A and B.
