    More information

    DDR3L 240-pin DIMM

    Desktop modules that operate at speeds up to 1600 MT/s and have a CL11 latency. It is dual voltage and can operate at 1.35V or 1.5V. It is Unbuffered and is non-ECC. It conforms to the industry standard UDIMM layout of 240 pins and is compatible with computers that take DDR3 UDIMM memory.

    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.

    If your upgrading an OEM computer, Save yourself time and money, order your memory needs from Crucial. What they recommend will work. I tried several brands of memory in my OEM computer and they were not compatible, even though they met the computer specs. I was going to give up but I tried what Crucial recommended for my computer and its now running with 16GB of memory, without any issues.

    This memory did the trick

    Comments about Crucial 8GB Kit (2 x 4GB) DDR3L-1600 UDIMM:

    Dell Vostro 260s desktop was running slow, especially with multiple applications open. Search on web suggested that we needed machine specific, rather that generic Ram cards. Found the appropriate product on this supplier's website. Took out the two original 2Gb Ram cards and replaced with 2 x 4 Gb Crucial cards and PC is now running sweetly.

    Comments about Crucial 8GB Kit (2 x 4GB) DDR3L-1600 UDIMM:

    I had 4 GB of memory in my HP Compaq 8000 and when we went to a web based server with Office 365 I was constantly pushing up against that limit and the computer was slowing to a stall - I swapped out the four 1 GB modules for four 4 GB modules - took about 10 minutes total - and now no delays, no stalls, no waiting for data to write to the hard drive - it's like having a new computer

        Added 8GB of Crucial Memory to a 5 year old HP bringing the memory to 12GB. The machine now flies. Over the years I've always gotten my memory from Crucial because it works and if there is an issue, they correct it quickly - even if the issue was with my ordering the wrong memory.

        I ordered an upgrade kit for my HP Desktop. What I like best is the search and match feature that gives me the exact options for my PC. I had some questions and chat support was very helpful - giving me options and helping me understand the pros and cons of each.
