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.
The memory I need has been out of stock for a really long time. Is there anything else that will work? Is there any way to cross reference Crucial kit part numbers (often available online at newegg.com or amazon.com) to be sure they are compatible before purchasing?
Thanks for your message.
I have looked in to the ASRock 775Dual-VSTA system and we recommend that the maximum memory it can take is 2GB in total. That's 2x1GB modules.
You said that you currently have 3GB of memory installed. Sometimes you can go above the manufacturers recommendation but there is no guarantee that your system would work with 4GB installed.
I would be more than happy to recommend a single 2GB module for you. What I would need first would be some details about your existing 2GB module. This is so I can match it as much as possible when recommending memory.
On the existing memory module there will be a sticker that gives you details about the speed of the memory module. It will say something like "PC2-6400". Can you confirm what it says?
Once I have that information I can look at recommending memory that matches the speed of your existing memory. However, as we don't advise this system can support 4GB I cannot guarantee that it will work. All our memory does come with a lifetime warranty and also a 45 day return period.
If you do have any other questions at all, please don't hesitate to ask.
There are 4 possible upgrades for this PC:
The only difference I can detect is the choice among specs denominated as Cl-11, CL-13, 9-9-9-24, or 10-10-10-30.
Can anyone explain their significance. PC wil be used as stand alone single user client device.
Many thanks for advice.

now giving up... !!!!!
I plan to upgrade the memory of my netbook ASUS Eee 1015PX to 2GB. From the factory it has one Hynix HMT112S6TFR8C-H9 memory.
I used the tool on your website to identify the required Crucial memory. It recommends:
2GB DDR3 PC3-12800 Unbuffered NON-ECC 1.35V part #:CT5630031
for the upgrade.
According to the description, that is 1.35V memory, whereas the Hynix memory is 1.5V (+/- 0,075V).
Will the Crucial memory work in my machine?
