ok, but the X2 3800+ is a Manchester core, and I have read this article http://www.xbitlabs.com/articles/cp...lon64-x2_2.html
which talks of the advanced memory controller in the Manchester/Toledo cores.
This is the part of the article which im referring to:
"Athlon 64 X2 processors are based on the Toledo and Manchester cores with E stepping, i.e. their functionality is similar to that of the Athlon 64 processors on San Diego and Venice cores (except for the ability to process two computational threads simultaneously). Athlon 64 X2 also supports SSE3 instructions and features an enhanced memory controller. Among the peculiarities of the memory controller of the new Athlon 64 X2 I would like to mention the support of different memory DIMMs in different channels (it even allows installing memory modules of different capacity in different channels) and the support of up to four double-sided DIMMs in DDR400 mode."
Does your explanation still apply after reading this? thanks for the help.
