Phenom II only has a dual channel memory controller, you want to pair your memory in sets of 2. You don't want to put 3 sticks in your computer.

Channel ... smannel :lol:

With the K10 arch it really does not matter because for each 10% increase in the IMC/NB speed you will increase memory bandwidth 3-4% and reduce latency 3-4%.

Using a 720BE with no effort you can reach 2400MHz IMC/NB (a 20% increase) - 25-2600MHz with a little tweaking and voltage bump - and 27-2800MHz if you are an 'enthusiast' ...

The performance gains from the increased IMC/NB speed are greater than dual- or triple-channel memory performance gains.

And having 3Gb of total memory will always be better than having 2Gb (unless your memory fell off the back of a turnip truck)

I recommend Crucial's 4GB DDR3 1333 RAM (on sale at Newegg for $65 and free shipping). It's two sticks of 2GB Dual Channel memory, and you can easily bump it to 1600 with 8-7-7-18 timings.

------------------------------ Win 7 x64 | ASRock M3A780GXH/128M | Phenom II x720 BE 3.7GHz at 1.525V | 45C Idle - 61C Max | 4GB Crucial DDR3 1333 RAM at 1600 w/8-7-7-18 timings | GTS 250 512MB OC'd | $470 Total price of entire system.

I can prove you wrong real quick Wisecracker.

here is what an actual triple channel not overclocked looks like. mine is the red bar

Now if your gonna do better than this with a 720, I like to see it?

This isn't an AMD/Intel thread (in case you didn't notice).

And besides - apples and oranges - you haven't proved anything. Run dual-channel in your rig and prove my point.

I'm just proving you wrong buy your statement of better then any dual/tripple channel setup. That's all
