- I thought in order to use dual channel memory that identical RAM has to be installed in each channel. And I thought each channel had its own color. IOW if there were 2GB in a black slot then there should be 2GB in a blue slot. And from this thread it states 'Install these in 'paired' slots - usually slots 1 & 3 or 2 & 4'.

In the fields of digital electronics and computer hardware, multi-channel memory architecture is a technology that increases the data transfer rate between the DRAM memory and the memory controller by adding more channels of communication between them. Theoretically this multiplies the data rate by exactly the number of channels present. Dual-channel memory employs two channels. The technique goes back as far as the 1960s having been used in IBM System/360 Model 91 and in CDC 6600.[1]
Modern high-end processors like the IntelCore i9 and AMDRyzen Threadripper series, along with various Intel Xeons support quad-channel memory. In March 2010, AMD released Socket G34 and Magny-Cours Opteron 6100 series[2] processors with support for quad-channel memory. In 2006, Intel released chipsets that support quad-channel memory for its LGA771 platform[3] and later in 2011 for its LGA2011 platform.[4] Microcomputer chipsets with even more channels were designed; for example, the chipset in the AlphaStation 600 (1995) supports eight-channel memory, but the backplane of the machine limited operation to four channels.[5]
Dual-channel architecture[edit]
Dual-channel-enabled memory controllers in a PC system architecture use two 64-bit data channels. Dual-channel should not be confused with double data rate (DDR), in which data exchange happens twice per DRAM clock. The two technologies are independent of each other, and many motherboards use both by using DDR memory in a dual-channel configuration.
Operation[edit]
Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2, DDR3, DDR4, or DDR5 memory modules. The memory modules are installed into matching banks, each of which belongs to a different channel. The motherboard's manual will provide an explanation of how to install memory for that particular unit. A matched pair of memory modules may usually be placed in the first bank of each channel, and a different-capacity pair of modules in the second bank.[6] Modules rated at different speeds can be run in dual-channel mode, although the motherboard will then run all memory modules at the speed of the slowest module. Some motherboards, however, have compatibility issues with certain brands or models of memory when attempting to use them in dual-channel mode. For this reason, it is generally advised to use identical pairs of memory modules, which is why most memory manufacturers now sell 'kits' of matched-pair DIMMs. Several motherboard manufacturers only support configurations where a 'matched pair' of modules are used. A matching pair needs to match in:
- Capacity (e.g. 1024 MB). Certain Intel chipsets support different capacity chips in what they call Flex Mode: the capacity that can be matched is run in dual-channel, while the remainder runs in single-channel.
- Speed (e.g. PC5300). If speed is not the same, the lower speed of the two modules will be used. Likewise, the higher latency of the two modules will be used.
- Same CAS Latency (CL) or Column Address Strobe.
- Number of chips and sides (e.g. two sides with four chips on each side).
- Matching size of rows and columns.
Dual-channel architecture is a technology implemented on motherboards by the motherboard manufacturer and does not apply to memory modules. Theoretically any matched pair of memory modules may be used in either single- or dual-channel operation, provided the motherboard supports this architecture.
Performance[edit]
Theoretically, dual-channel configurations double the memory bandwidth when compared to single-channel configurations. This should not be confused with double data rate (DDR) memory, which doubles the usage of DRAM bus by transferring data both on the rising and falling edges of the memory bus clock signals.
A 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.[7]:p. 5 Other tests performed by TweakTown on the same subject showed no significant differences in performance, leading to a conclusion that not all benchmark software is up to the task of exploiting increased parallelism offered by the multi-channel memory configurations.[7]:p. 6
Ganged versus unganged[edit]
Dual-channel was originally conceived as a way to maximize memory throughput by combining two 64-bit buses into a single 128-bit bus.[disputed][citation needed] This is retrospectively called the 'ganged' mode. However, due to lackluster performance gains in consumer applications,[8] more modern implementations of dual-channel use the 'unganged' mode by default, which maintains two 64-bit memory buses but allows independent access to each channel, in support of multithreading with multi-core processors.[9][10]

'Ganged' versus 'unganged' difference could also be envisioned as an analogy with the way RAID 0 works, when compared to JBOD.[11] With RAID 0 (which is analogous to 'ganged' mode), it is up to the additional logic layer to provide better (ideally even) usage of all available hardware units (storage devices, or memory modules) and increased overall performance. On the other hand, with JBOD (which is analogous to 'unganged' mode) it is relied on the statistical usage patterns to ensure increased overall performance through even usage of all available hardware units.[9][10]
Triple-channel architecture[edit]
Operation[edit]
DDR3 triple-channel architecture is used in the IntelCore i7-900 series (the Intel Core i7-800 series only support up to dual-channel). The LGA 1366 platform (e.g. Intel X58) supports DDR3 triple-channel, normally 1333 and 1600Mhz, but can run at higher clock speeds on certain motherboards. AMD Socket AM3 processors do not use the DDR3 triple-channel architecture but instead use dual-channel DDR3 memory. 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). According to Intel, a Core i7 with DDR3 operating at 1066 MHz will offer peak data transfer rates of 25.6 GB/s when operating in triple-channel interleaved mode. This, Intel claims, leads to faster system performance as well as higher performance per watt.[12]
When operating in triple-channel mode, memory latency is reduced due to interleaving, meaning that each module is accessed sequentially for smaller bits of data rather than completely filling up one module before accessing the next one. 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.
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. When two memory modules are installed, the architecture will operate in dual-channel architecture mode.[13]

Quad-channel architecture[edit]
Operation[edit]
Quad-channel DDR4 has replaced DDR3 on the Intel X99LGA 2011 platform, and is also used in AMD's Threadripper platform.[16]DDR3 quad-channel architecture is used in the AMDG34 platform and in the Intel X79LGA 2011 platform. AMD processors for the C32 platform and Intel processors for the LGA 1155 platform (e.g., Intel Z68) use dual-channel DDR3 memory instead.
The architecture can be used only when all four memory modules (or a multiple of four) are identical in capacity and speed, and are placed in quad-channel slots. When two memory modules are installed, the architecture will operate in a dual-channel mode; when three memory modules are installed, the architecture will operate in a triple-channel mode.[13]

When the DCTs are in ganged mode, as specified by [The DRAM Controller Select Low Register] F2x110 [DctGangEn], then each logical DIMM is two channels wide. Each physical DIMM of a 2-channel logical DIMM is required to be the same size and use the same timing parameters. Both DCTs must be programmed with the same information (see 2.8.1 [DCT Configuration Registers]). When the DCTs are in unganged mode, a logical DIMM is equivalent to a 64-bit physical DIMM and each channel is controlled by a different DCT. Typical systems are recommended to run in unganged mode to benefit from the additional parallelism generated by using the DCTs independently. See 2.12.2 [DRAM Considerations for ECC] for DRAM ECC implications of ganged and unganged mode. Ganged mode is not supported for S1g3, S1g4, ASB2, and G34 processors.

A memory slot, memory socket, or RAM slot allows RAM (computer memory) to be inserted into the computer. Most motherboards have two to four memory slots, which determine the type of RAM used with the computer. The most common RAM types are SDRAM and DDR for desktop computers and SODIMM for laptop computers, each having various types and speeds. The picture below is an example of what memory slots may look like inside a desktop computer. In this picture, there are three open and available slots for three memory sticks.
When buying a new computer or motherboard, pay close attention to the types of RAM the memory slots can accept. Make sure you know exactly the type of RAM to buy for your computer. It is also important to note how many available memory slots are available in your computer. It is not uncommon for computers to have all memory slots occupied. If all slots are full and you want to upgrade the computer memory, you need to remove some or all of the existing memory.
Why are the memory slots different colors?
Difference Between Blue And White Ram Slots 2020
When a motherboard has different colored memory slots, it indicates the memory slots are dual-channel, and pairs of memory should be installed on the same channel (color). For example, a motherboard could have two yellow and two black memory slots. The yellow memory slots could indicate Channel A and Channel B could be indicated by the black slots. If you were only installing two memory sticks, you'd want to install both of them in Channel A (yellow slots) for optimal performance.
