Why dual channel can be this faster than triple channel?

Why dual channel memory can be this faster than triple channel memory?

They have the same spec!!

Left one is 4.2GHz i7 with dual channel at 2000 8-10-8-24-1T.
Right one is 4.2GHz i7 with triple channel at 2000 8-10-9-24-1T.

Both of them have a uncore frequence of 4000MHz and same voltage.

Dual shows 2500MB/s in read faster than triple,
4000MB/s faster in write
and 10ns in latency!

How incredible!It does not make sense! Ok guys, if dual can beat triple, why should we go triple?

This is exactly why SB went with Dual-Channel, it's easier on the IMC to access two sticks compared to three also.

The memory controller is faster thats all as it's new. Lower latency.

Nothing to do with amount of sticks it has to access. The new IVybridge is going to be quad- channel apparently.

I totally agree.

This is only one benchmark.

Triple-channel provides benefit in application where there are large blocks of data being read/written. Most people don't ever deal with this type of work.

Folders like triple channel.

So many end up seeing bad performance compared to others and then they realized they were in dual channel from placing the sticks in the wrong slots.

Would triple channel be benificial over dual channel for audio editing/mastering (Cubase 6 etc)?
In specifics, I consider buying tripple channel combined with my I7 920 D0 and Rampage II extreme

I don't think so, since dual channel is already more than enough

There was another thread about this before. My aida 64 memory benchmarks were slightly worse in some test areas when running in triple. However the triple channel performed better in a number of cpu and memory combined benchmarks and I actually got a better 3dmark11 score.
