Memory interleaving

Hi,

Is there a reference anywhere that explains the benefits for memory interleaving on the HP Proliants, and how it works ?

Thanks
Andrew

Background

For background information on the Intel Dual Channel Memory Architecture, please see these documents:

Intel Dual Channel DDR Memory Architecture White Paper
http://www.kingston.com/newtech/MKF_520DDRWhitepaper.pdf

Dual Channel DDR400 memory can balance the performance of the Intel Pentium 4 processor with 800MHz front side bus.

Personal Experience

In June 2005 I received a ProLiant ML110 G2 with a single factory-fitted 256MB DIMM. I installed a matched pair of PC3200/DDR400 DIMMs - in the correct sockets - and measured the following memory performance improvement:

ProLiant ML110 G2 ( Model 382050 / Pentium 4, 3.2GHz )
Single DIMM 2947 MBytes / sec
Dual DIMMs 4664 MBytes / sec
( SiSoft SANDRA benchmark )

The Intel and Kingston documents suggest that this results in a 10-25% improvement in overall system performance.
