More information

Memory spec terms
If you're not sure if a module is right for your system, use the Crucial Memory Advisor tool for a list of guaranteed compatible modules.

NON-ECC/Non-parity Most desktop and laptop computers take NON-ECC or Non-parity memory.

ECC/Parity ECC or parity modules look for errors in data and are most often found in servers and other mission-critical applications used by large networks and businesses.

Unbuffered Most PCs and workstations use unbuffered memory which is faster than registered memory.

Registered/Buffered Registered or buffered modules delay all information transferred to the module by one clock cycle. This type of memory is primarily used in servers.

Fully buffered Designed for next-generation servers, features an advanced memory buffer.

CL —CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Lower CL is faster. Modules with different CL can be mixed on a system, but the system will only run at the highest (slowest) CL.

Component configuration —(For example: 64Meg x 64) Indicates the size of the memory chip components on the module.

Voltage For example 2.6V. Indicates the power used by the module. The lower the better.

DDR3 240-pin DIMM

Crucial 240-pin DIMMs are used in DDR3 memory for desktop computers. DDR3 is the latest generation of memory with an improved architecture that allows it to transmit data more quickly.

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.

Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or Fully Buffered modules).

To use DDR3 memory, your system motherboard must have 240-pin DIMM slots and a DDR3-enabled chipset. This is because a DDR3 SDRAM DIMM will not fit into a standard DDR2 DIMM socket or a DDR DIMM socket.

The number of black components on a 240-pin DIMM can vary, but it always has 120 pins on the front and 120 pins on the back, for a total of 240. 240-pin DIMMs are approximately 5.25 inches long and 1.18 inches high, though the heights can vary. While 240-pin DDR3 DIMMS, 240-pin DDR2 DIMMs, 184-pin DDR DIMMs, and 168-pin DIMMs are approximately the same size, 240-pin DIMMs and 184-pin DIMMs have only one notch within the row of pins

100% Incompatible Compatible Memory

By DazzaBee

from Bexhill on Sea

Pros

• Good Company
• Good Memory
• Good Sevice

Cons

• Memory Not Compatible

Best Uses

• Pc

Comments about Crucial 4GB 240-pin DIMM DDR3 PC3-14900:

I used the compatibility scan tool on the Crucial Website to identify the correct memory. The tool identified my system correctly and suggested a number of options, all of which it said were 100% compatible. It arrived and looked good but after several tests, it became clear the memory modules were simply not compatible as suggested. This for me was a great shame as I have bought memory from crucial before with no problems hence my return visit.

Bottom Line No, I would not recommend this to a friend
