In other words, dual channel works by accessing two memory modules in parallel, i.e.

If you install just one module this technique won’t work because memory will still be accessed 64 bits per cycle. Because of that they achieve double the transfer rate compared to traditional memories (such as the original SDRAM) running at the same clock rate.įor dual-channel technology to work you need to have an even number of memory modules on your system (assuming that your AMD CPU or Intel chipset support this technology, of course). Memories based on DDR (Double Data Rate) technology such as DDR-SDRAM, DDR2-SDRAM and DDR3-SDRAM transfer two data per clock cycle. Considering that everything remains the same (clock speeds, for example), the memory maximum theoretical transfer rate is doubled by the use of this technique. Alternate is not right here.Ī good article discussing Dual-Channel RAM,Įverything You Need to Know About Dual Channelĭual channel is the ability that some memory controllers have to expand the width of their data busses from 64 to 128 bits.

Select Memory and continue to purchase the memory.Looking at your board it appears that Slot#1 and Slot#2 (colored black?) should be used for the memory - this ASUS board has 3 memory slots instead of the usual 4 and they are organized differently.

Identify your Dell computer using the Service Tag or Express Service Code.

A 64-bit version of operating system can support system memory that is greater than 4 GB. Adding a higher capacity memory in such cases does not improve the performance as the operating system cannot take advantage of the available memory.

If the computer is installed with a 32-bit version of Windows or other operating systems, the operating system can only recognize 4 GB of memory.

See the documentation of your Dell computer for model-specific information. For example, if your laptop with 2 memory slots supports a maximum of 16 GB of memory, you can install 2 x 8 GB memory modules. Often laptops have 2 memory slots, and desktops may have more than 2.

Every computer has a specific number of memory slots on the system board.

For example, a particular Dell desktop or laptop may support a minimum of 2 GB and maximum 16 GB of memory.

Every computer is designed to work with a minimum and maximum capacity of memory.

What is the maximum capacity that is supported by the computer?.

WARNING: Installing an incorrect or unsupported type of system memory (RAM) on the computer may cause physical damage to either the module or the slot on the system board.
