Dual Channel Memory Controller
However, if no interleaving is done, the memory controller may be blocked while it waits for another read operation on the same bank to complete. Therefore, in order for the dual-channel architecture to work, you will need to install two memory modules in parallel, making 128 bits available. Almost always the memory slots will be color coded to indicate the memory channel, as shown in the picture below. Finally, if you are only installing two memory modules at a time make sure the memory is installed into the proper memory slots. http://webtrekkie.com/dual-channel/dual-channel-memory.php
The architecture can only be used when all three, or a multiple of three, memory modules are identical in capacity and speed, and are placed in three-channel slots. Theoretically any matched pair of memory modules may be used in either single- or dual-channel operation, provided the motherboard supports this architecture. All four memory sticks do not need to be the same, just the pairs need to be the same and installed in their proper memory slots. Enabling Dual Channel (Intel and AMD Socket AM3+)6. https://en.wikipedia.org/wiki/Multi-channel_memory_architecture
Dual Channel Memory Vs Single
For this reason, it is generally advised to use identical pairs of memory modules. In 2006, Intel released chipsets that support quad-channel memory for its LGA771 platform and later in 2011 for its LGA2011 platform. Microcomputer chipsets with even more channels were designed; for example, Another benchmark performed by TweakTown, using SiSoftware Sandra, measured around 70% increase in performance of a quadruple-channel configuration, when compared to a dual-channel configuration.:p. 5 Other tests performed by TweakTown on
Just as with dual-channel architecture memory should be installed in a set of three or four depending on the architecture of the motherboard.

Keep doing it everyone!! Dual Channel Memory Installation The memory modules are installed into matching banks, which are usually color-coded on the motherboard. Without any interleaving, the memory controller would have to perform four separate read operations from the same row (or two rows if it crosses a row boundary) from a single bank.Similarly, http://www.computerhope.com/jargon/d/dual-channel-memory.htm The technique goes back as far as the 1960s having been used in IBM System/360 Model 91 and in CDC 6600.

I haven't used an AMD microprocessor in years though so I'm just going off of memory (pun intended) here.What I would recommend is adding 2x8 GiB to your existing 2x4 GiB Dual Channel Memory Explained The dual-channel platform helps alleviate bottlenecks that occur. Another benchmark performed by TweakTown, using SiSoftware Sandra, measured around 70% increase in performance of a quadruple-channel configuration, when compared to a dual-channel configuration.:p. 5 Other tests performed by TweakTown on hapkidoOct 25, 2013, 6:51 PM If you had a motherboard/CPU with a quad-channel memory controller, you'd want 4x2 GB RAM instead of 2x4 GB.
Dual Channel Memory Installation
If the speeds differ, the motherboard runs the memory chips at the speed of the slowest chip. http://www.hardwaresecrets.com/everything-you-need-to-know-about-the-dual-triple-and-quad-channel-memory-architectures/ i found this site.

Quad Channel Memory Vs Dual Channel The architecture can only be used when all three, or a multiple of three, memory modules are identical in capacity and speed, and are placed in three-channel slots.

TimingsThat's not to say I haven't managed to find some workloads that scale with channel interleave at the bottom of that list, but in these cases, the performance advantage of going Dual Channel Crossword Dual-channel memory, on the other hand, utilises two funnels, thereby having the capability to deliver data twice as fast, at up to 128 bits at a time.
Tradesman1Nov 1, 2014, 2:29 AM Intel in Dual channel sees the DRAM as a 128 bit device, in tri channel on 1366 as a 192 bit device and in quad mode Some motherboards, however, have compatibility issues with certain brands or models of memory when attempting to use them in dual-channel mode.

Without any interleaving, the memory controller would have to perform four separate read operations from the same row (or two rows if it crosses a row boundary) from a single bank.Similarly, Help? These separate channels allow each memory module access to the memory controller, increasing throughput bandwidth. It is not required that identical modules be used (if motherboard supports it), but this is often recommended for best dual-channel operation.
The same applies to the Intel Core i3, Core i5 and Core i7-800 series, which are used on the LGA 1156 platforms (e.g., Intel P55). Enabling Dual Channel5. See 2.12.2 [DRAM Considerations for ECC] for DRAM ECC implications of ganged and unganged mode. Dual-channel-enabled memory controllers in a PC system architecture utilize two 64-bit data channels.
LimpanOct 31, 2014, 1:02 PM mdocod said: Limpan said: please correct me if I'm wrongRegardsLimpan A single channel can often achieve the best latency characteristics compared with multi-channel configurations, however, it's ISBN978-0-12-379751-3. ^ a b "Opteron 6000 Series Platform Quick Reference Guide" (PDF). Data is spread amongst the modules in an alternating pattern, potentially tripling available memory bandwidth for the same amount of data, as opposed to storing it all on one module. That's Ganged mode.
However, loading the same data set using bank interleaving requires opening four rows on four banks on one channel (banks 0,1,2,3) and burst transferring from all of them sequentially.

Dual-channel lets one controller handle the reading and writing while the other controller prepares the next access thus preventing a delay. A matching pair needs to match in: Capacity (e.g. 1024MiB). And thats odd that 1 module costs a lot less. Dual Channel Memory solved Dual channel vs single channel memory Dual Channel vs Single channel memory upgrade: Dell Server Memory: dual channel vs single Can't find your answer ?
Dual-channel-enabled memory controllers utilize two 64-bit data channels, resulting in a total bandwidth of 128-bits, to move data from RAM to the CPU.
