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.

Q:My laptop has a crucial ct1007836 1gb installed (as scan recommended) can I use this ct12864Z40B alongside to bring up to max 2gb memory recommended? thanks
A:Yes you certainly can. It will run at the same speed as your existing 1GB part.
Q:Does this work with dell and intel chipset?
A:We would need to know the exact model of Dell system you have before we could guarantee the compatibility. Please confirm your system details and we can confirm if this memory is compatible.
Q:Not mentioned, so does this memory support SPD?
Q:Can I use this (Part number: CT12864Z40B) in place of part number: CT478526 in my Compaq Presario SR1610NX Desktop PC? They appear to be the same. If not what is the difference between them?
A:They are actually the same part the only difference is that CT478526 is a Kit of two memory modules. Both are fully compatible with your system.
A:Using my external brain (Google), I was able to determine that both part numbers refer to sticks of the same configuration. It appears one is a single stick and the other a kit of two identical sticks.
Q:Is this RAM low density?
A:Yes, it is standard low density.
Q:I have an Apple Power Mac G5 dual 2.7 GHz, model G85386YURU4. Will a pair of these chips work? thanks
A:Yes. The Apple Power Mac G5 dual 2.7 GHz can support a maximum of 8GB over the 4 slots (1GB per slot) so you certainly be able to use the above mentioned memory module in your system.
I ran the scan, it takes me to this page,
CT3694396 - 8GB DDR3 PC3-12800 Unbuffered NON-ECC 1.5V 1024Meg x 64
I am sorry for the issues that you have been experiencing with your new RAM. How much RAM is found when you use our System Scanner. This scanner can be found here. If a module is missing (scanner shows empty slot), it's likely an installation issue.If the modules are half detected by the scanner, it could be a density issue. Please check the scanner and let us know and we can see what other troubleshooting we may be able to try.
got a rare bluescreen 0x0000001a "Memory Management".
My Motherboard is a Gigabyte H97 HD3. (Bios F4)
The Crucial Ram is a 8GB-Kit PC3 - 12800 CL9, 1.5v
I tested both sticks (together) with memtest for 12 passes overnight (0 errors),
Does it make sense to test each on its own ?
Are these components incompatible ?
