Hey folks, is there a noticable difference between dual v.s. quad channel memory?

post #1 of 5
Thread Starter 
First off, thanks for taking the time to read this.

I'm currently building a PC and I'm split between a 3930K and a 2600K.
Apparently the 3930K has an Integrated Four Channel DDR3 Memory Controller, while the
2600k is Dual Channel DDR3-1066/1333.

So how great of a handicap is a dual channel v.s. quad? and can the 2600k only run RAM at max of 1333?

Again, thanks.

Don't know the answer for the first question, but I have my 2600K paired with 1866MHz sticks. I think the max is either 2133/2400.

Four channel is because X79 chipsets can have 8 memory slots. So, no, there would be no difference between the two.
And The i7 2600k speed limit is not 1333. It's like 2400MHz like importflip said.

2600K only officially (Intel backed) supports up to 1333 MHz. Anything above is considered overclock and is not guaranteed to work.

The difference between dual and quad channel will only starts to show when you fold, crunch, or do heavy RAM task.

Quad channel is great for memory intensive programs. You won't see much of a difference for gaming, games just don't use that much bandwidth.
