A Note about Dual-Channel

post #1 of 2
Thread Starter 
Preface: Most of you familiar with folding will find this to be old news, but more proof / evidence can never hurt.

So I got some new desktops at work recently, and of course I just HAD to test their folding prowess. The systems came configured with an Intel Core-i3 2120 CPU (3.3GHZ, HT no Turbo). They also came configured with 4GB DDR3-1333 in SINGLE CHANNEL mode (1 DIMM).

Anyway, I stole a memory module out of one of the systems to test in dual channel vs single channel mode.

Results:

Project 6057

Single Channel TPF: 6:20s

Dual Channel TPF: 5:55s

In Conclusion, even this lowly CPU receives a nearly 7% boost in TPF going from single -> dual channel memory. Again, nothing earth shattering or even surprising, but noteworthy nonetheless.

Just thought I would share this with everyone!

Might not be earth-shattering for SMP WUs, but for -bigadv, it makes a pretty big difference.
