Channel interleave2. Dual channel should not be confused with double data rate (DDR), in which data exchange happens twice per DRAM clock. 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 The wires from the address bus tell the memory modules exactly where (which address) that data must be retrieved or stored. my review here

Dual-Channel Architecture: How Dual-Channel RAM Platforms Work If you already understand the basic, top-level concepts of multichannel platforms as it pertains to memory, you can skip this part and jump into Other concerns arose with memory saturation. 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. It made sense to just leave it as 'Gamers.'" First world problems, Steve. http://www.computerhope.com/jargon/d/dual-channel-memory.htm

Dual Channel Memory Vs Single

During this wait time the CPU is idle, doing nothing (that’s not entirely true, but it fits our explanation). Speed (e.g. 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. Dual-Channel - Does It Matter?

In Figures 1 and 2, we compare the two approaches. Dual Channel Ram Different Size The aim is to debunk or confirm a few myths about computer memory.

Number of chips and sides (for example; 2 sides with 4 chips on each side). Dual Channel Motherboard As far as I know, memory channels on AMD's platforms must be balanced. Motherboards supporting dual-channel memory layouts typically have color-coded DIMM sockets. http://www.tomshardware.com/forum/326321-30-single-memory-dual-channel Read on for the real performance impact.

But in the real world you won't see much difference except in benchmarks. Quad Channel Ram Dual-channel with two DIMMs Dual-channel with three DIMMs Dual-channel with four DIMMs Rules to enable dual-channel mode To achieve dual-channel mode, the following conditions must be met: Same memory size. Dual-channel configurations would show significant advantage in render, encoding, and transcoding applications (for video and incompressible audio).

Dual Channel Motherboard

Applying both synthetic and real-world tests is important; without synthetic tests, we can't adequately isolate memory performance and make extrapolations / predictions for real-world tests. http://acer.custhelp.com/app/answers/detail/a_id/1664/~/what-is-dual-channel-memory%3F 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 Dual Channel Memory Vs Single This model comes in (2x8GB). Dual Channel Ddr4 Currently, most processors have this component embedded, so the CPU has a dedicated memory bus connecting the processor to the RAM.

Retrieved 2012-10-15. ^ "AMD Opteron 6300 Series processor Quick Reference Guide" (PDF). this page Data is spread through the memory modules in an alternating pattern. In order to achieve this, two or more DDR/DDR2/DDR3 SDRAM memory modules must be installed into matching banks. Figure 1: How the RAM is accessed on CPUs with an integrated memory controller Figure 2: How the RAM is accessed on CPUs without an integrated memory controller The RAM is Dual Channel Ram Installation

I will define the RAM modules below. We're testing the performance of two sticks of 2x4GB (more on the platform specs & methodology below) in single- and dual-channel configurations. The channel effectively runs between the memory controller or chipset and the memory socket; in the case of modern architectures, the memory controller is often integrated with the CPU, rather than get redirected here According to Intel, a Core i7 with DDR3 operating at 1066MHz will offer peak data transfer rates of 25.6GB/s when operating in triple-channel interleaved mode.

Tradesman1Jul 23, 2013, 7:39 PM Good point Didn't even look at the dates, I saw it when Victorst responded..... Double Sided Memory Quad-channel mode This mode is enabled when four (or a multiple of four) DIMMs are identical in capacity and speed, and are put in quad-channel slots. When active your initial boot screen that displays your memory speeds and capacity should show "Dual Channel" or "Dual Channel Interleaved" somewhere in the memory settings.

Almost always the memory slots will be color coded to indicate the memory channel, as shown in the picture below.

Dual-channel (interleaved) mode This mode offers higher memory throughput and is enabled when the memory capacities of both DIMM channels are equal. For dual-channel, you only need to install memory in pairs. When the memory is unable to keep up with the processor, however, a bottleneck occurs, leaving the CPU with nothing to process. Triple Channel Memory It is possible to use a single-sided module of 512 MB and a double-sided module of 512 MB in dual-channel configuration, but how fast and stable it is depends on the

Dual-Channel Benchmark Results Memory has a tendency to get largely overlooked when building a new system. This is compared against 64 for single-channel platforms and 256 for quad-channel platforms. After my preliminary tests that indicated dual-channel performance might not be quite as substantial as I'd always thought, my considerations changed. useful reference PinheddNov 1, 2014, 1:02 AM Tradesman1 said: Yes dual channel is faster, can be up to 10-15% on Intel, single channel runs the DRAM as the single 64bit device that it

Home » Gaming » Does dual-channel memory make difference in gaming performance? Our only test that nearly filled the entire capacity was the After Effects RAM preview. Re: Upgrading Ram on Aspire R7 Answers others found helpful Why is the system memory reporting in System Information less than 4GB with 4GB or more installed? Ganged mode is not supported for S1g3, S1g4, ASB2, and G34 processors. ^ Rouse, Margaret (September 2005). "JBOD (just a bunch of disks or just a bunch of drives)".

Further, note that channel configurations could (not tested) and frequency will have a significant impact upon APUs and IGPs, so these test results are strictly targeted at systems that don't rely Online since 1999. Veröffentlicht am 05.02.2013Dual channel, triple channel, quad channel?
