Dual channel Hmmmmm ?.

[bushmaster]

This (http://www.msi.com.tw/html/e_service/techexpress/tech_column/2channel/page1.htm) over at MSI makes for serious consideration when considering to build AMD or Intel to take full advantage of dual channel DDR.
It seems as though the Intel architecture better utilizes DCDDR and reaps over a Ghz/s of added bandwidth from the dual configuration. And the AMD architecture only gets a boost of 98MB/s and 4MB/s respectively.

So is that just because of the MSI board, the chipset or the processor?

The Two Channel DDR structure uses Twin Bank mode, and requires two memory modules plugged into the appointed DIMM slots in order to enable 2 Channel DDR. Though E7205 only supports DDR266 memory, its 4.3GB/s memory bandwidth will still outperform the Single Channel in DDR400 in terms of performance.


It sounds similar to RAID technology to me, two sticks of same make, same size...giving double the bandwidth but not only half the size. i.e. two 512 sticks giving double the bandwidth but only 512mbs of RAM (not 1024)

That however is a guess from the info on that page, correct me if I am wrong....

Amd seems not benefittin much with Dual DDR.

probably the chipset and the processor's bandwidth requirements.

From what I've heard it's the processor that's holding back the performance of dual channel memory for AMD. It might also be the chipset to some extent, since it wouldn't surprize me at all to learn that an Intel chipset has a superior memory controller. However, I still think it's mostly the processor. I would tend to believe that it's not the MSI board specially to any significant extent. First, I don't see MSI themselves posting benchmarks that make their own board look bad. Second, I've seen benchmarks of various nForce2 boards, and MSI is generally in the middle of the pack, not much worse or better than any other.

No it's not just the MSI boards. This was just the first that I had seen a manufacturer of both AMD and Intel boards publish a document that could possibly lower sales of a product.
And it's both the chipset and processor that limit the advantage of DCDDR on the AMD based boards.

I was considering upgrading from the MSI K7N2-L that I'm using now to the K7N2-ILSR Delta. But since reading about this I'm going to sell the K7N2-L/XP2600 system I just built and start again with the MSI 875P Neo-FIS2R as seen here (http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=434&MODEL=MS-6758) when it's available in the U.S.

Looks like Intel's going to be coming back hard and heavy this year.

nice features for an MSI board....evrytime somethin nice comes out i feel like upgradin....still will wait though.
