A dual inline memory module (DIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The gold pins on the bottom of the DIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a DIMM are not connected to each other.
184-pin DIMMs are used to provide DDR SDRAM memory for desktop computers. Standard 184-pin DIMMs are available in PC1600 DDR SDRAM, PC2100 DDR SDRAM, PC2700 DDR SDRAM, and PC3200 DDR SDRAM.
To use DDR memory, your system motherboard must have 184-pin DIMM slots and a DDR-enabled chipset. A DDR SDRAM DIMM will not fit into a standard SDRAM DIMM socket. (Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool.)
The number of black components on a 184-pin DIMM can vary, but it always has 92 pins on the front and 92 pins on the back, for a total of 184. 184-pin DIMMs are approximately 5.25 inches long and 1.25 inches high, though the heights can vary. While 184-pin DIMMs and 168-pin DIMMs are approximately the same size, 184-pin DIMMs have only one notch within the row of pins.
Thanks for your question. I have looked in to that system for you and it can support 2GB of memory in total and it has two memory slots. Each memory slot can support 1GB each. This means the 2x2GB memory modules would not work in your system.
We would need to see the part numbers of the memory modules you have received before we can confirm if they are compatible for you. When you receive the new memory modules it would be great if you could post on here with the part numbers that are listed on the memory modules. This way we can check if they are the correct speed and type for your computer. The part numbers will be printed on a sticker on the side of your memory module.

1. Ran the scan on desktop pc at crucial.com
Maximum memory: 8192MB
Slots: 2 (2 banks of 1)
*Not to exceed manufacturer supported memory.
Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.
2. Existing memory is 2 GB - occupies one of the two memory slots
3. Purchased 2 x 2GB Crucial 4GB Kit from Amazon -
4. Both memory slots filled - memory is read on boot up but......
5. Unfortunately the new memory does not work????? Put existing 2GB memory module back in slot.
Thanks for your help,
I'm an IT engineer and subscribred to this feed.
In looking up RAM for new laptops I occasionally find model numbers off by a digit or letter.
Many times these minor differences are owing to different HD or SSD, Optical drive, touchscreen, etc.
My question is; if model numbers are not an exact match, can this also mean the RAM is not upgradeable?
Thanks for your message.
So I can look in to this part further can you provide some more information for me? On the module each black DRAM chip will have the manufacturer printed on it in small writing, can you confirm what that says?
The sticker on the memory module will also show the batch number of the memory module. The batch number is generally listed as something like BL111f5.7k.
If you can provide the above information then I can certainly look into this for you.
