For your perusal: http://www.hardwaresecrets.com/article/133

Good job explaining it to me, though. I especially enjoyed the condescending attitude.

 

I wasn't trying to be condescending.  I was confusing memory speed and bandwidth though ;)  You're right, I was wrong.

 

It does make me wonder if I would see a bump in PPD if I went to quad-channel, instead of the dual-channel config I'm running now.

Well... It would seem our i7-2 folder, has gotten more points with his 3770K than yours...

Buzzin! WHEN YOU GET A NEW MOTHERBOARD?!

Stop fighting in the middle of my war! tongue.gif

I haven't read the whole article yet, but from what I could tell the article you've linked to is correct krem. I'm reviewing some of the videos from the coursera computer architecture course, I want to agree that more channels and higher speed doesn't necessitate more bandwidth. What I really want to do is just upload the video, but I'm not sure the legality of that (even tho it is already free and open to anyone).

I will say that I hadn't noticed much, if any, increase in performance from dual channel to quad after my memory was back from RMA. Not that I was monitoring it very closely.

Peoples confusing Dual Channel and DDR tongue.gif

Dual Channel theoretically doubles memory bandwidth by splitting data between the channels, kinda like striped SSD's (RAID 0)

DDR is what turns 800MHz in to 1600MHz (Double Data Rate) As well as employing lots of stuff to do with memory timings, but I'm not gonna go in to that.

It's confusing, but trust me. That's what it is. tongue.gif

Oh and I'm on a ~26k credit WU, finishes in about 13 hours.

I downloaded mine. It cost $250 for 24GB, but it's totally worth it! It like mycleanpc.com - it just works!
