I sure would not want to be the one to defend DDR. The wider the bus, the greater the potential for "ground bounce."

I'm really impressed by MU's latest fix (not), adding resistor stubs.. this is something we did to "kluge" a fix when doing ATE fixtureing,,, not a design practice "real" engineers employ in high volume manufactured products.

The wheels are starting to come off the DDR wagon..

Hi h0db; Your post is quoting letters to the editor, not Overclockers itself.

Here's a link to the original Overclocker's article. Did you notice this little paragraph?

...
I purposely wanted to test a mix of modules to see how these boards would cope with such diversity. I used RAM Stress Test Professional (R.S.T. Pro) as the test tool. This is a stand-alone diagnostic card that plugs into a PCI slot. The card is self-booting - there is no OS to get in the way of results.

Here's the test tool:

Testing memory out of a PCI slot is likely a better test of the PCI system than it is a test of memory. Very few hobbiest motherboards are going to ever have a high bandwidth memory using device running out of the PCI slots. Interpreting the test results is problematical at best.

P.S. It must really rub your butt raw to be so certain that RDRAM is superior to DDR, while DDR outships it by at least 5 to 1 (and scheduled to reach 10 to 1 before the end of the year).
