Single channel VS Dual Channel RAM performance boost?

Hi.. So as usual im an idiot and i looked into my case and am still debating if my ram really should sit right next to eachother and i started Speccy and it said that i had single channel ram 2 different channels with 16GB total. I got confused becouse the motherboard manual said i should put the ram like i did.. So now i moved one ramstick, Whent into bios to check if everything was working like it should and now i have dual channel 16GB ram 8x2.
This started a question.. What performance boosts does dualchannel give over single channel.. I know its better but just. In what cases will it be "better" and will you notice it? And in witch scenario will you notice it?

almost all mother boards that have 4 ram slots have colour coding. the 2 the same colour, normally a space in between is the dual channel setup.

dual channel effectively doubles the memory bandwidth and halves the cache.

in real world terms youll get a 5-20% performance increase with dual channel when running bench marks.. you probably wont notice it in terms of speedyness though.

nope not really, and if you did it would only be 1 or 2. the difference between high and lpw latency ram in gaming makes almost no difference.

Well.. It looks better to have it say dual channel and not single channel atleast :P
But i've heard that using 2 sticks of ram both in single channel put a lot more strain on the memory controller than dual channel do with 2 sticks

Your best bet is to install the ram modules exactly as the motherboard manual stipulates.
Dual channel or single channel is the method the motherboard uses the installed ram. Dual channel can do more and do it faster. Basically dual channel has two roads to move information compared to one road.

At the present time motherboards come with Dual, Triple and Quad channel.
Your motherboard is a Dual channel.

This will make it easier to see if you are in Dual channel.
Yours should show Dual.
