I was just running the program Memtest86. I noticed the throughput (speed) of my PC2 6400 RAM in dual channel mode was running at 2,678 megabytes per second. That isn't even half of the 6,400 megabyte per second rating. Is my Athlon 4600+ Dual-Core processor bottlenecking the RAM at these speeds while it is running Memtest86?

I know the computer technology industry always brags about the throughput of different devices and you usually get about half of the speed that they advertise. (For example USB 2.0 advertises at 60 megabytes per second (480 megabits per second) transfer rates but you really only get 20 megabytes per second or lower.)
 
It could just be the way memtest runs, have you tried an actual benchmark to see the throughput?
 
I have never done this before other than with Memtest86. What programs can you use to monitor the actual throughput of data of the RAM?
 
I ran PC Wizard 2009 and it is showing my memory is running at 380 megahertz getting 5760 megabyte per second throughput speeds. That is certainly much better than the speeds I was getting with Memtest86.
