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.
I am sorry for the issues that you have experienced with your upgrade. What is the make and model of the computer that you were installing the memory in? What is the full part number on the memory module themselves? They should read CT25664AA800.16F,etc. Thank you in advance for this information.
August of 2013, a friend at church gave me this Compaq Presario 2004 desktop computer. He and his wife have moved to Minnesota and I have lost contact so cannot ask them. It only came with 256 Mb and the other slot is empty. A friend in Austrailia (I am in Atlanta, Georgia USA); also has an XP computer desktop but not the same brand. He shipped me 2 x 1 Gig and 2 x 2 Gig memory cards this past Wednesday. Will take 10-12 days to get to me. Do the memory cards have to be specific for my computer or will others work? Can I only put just 256 Mb more in the other slot? I am 64 (almost 65) and have never been inside a computer tower. A friend in my building will put the memory in for me. I am confused on how much Mb is 1 Gig and how much is 2? Here is the scan results for my computer: Crucial USA - scan results
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.
