"In case you did not know, the memory controller inside AMD's CPUs supports addressing of 11-bit columns while using 16K page size. In comparison, standard memory controllers on the market support 10-bit columns with 8K page size. In addition, AM2's controller can support as many as 2048 individual entries if a page size is 16Kbits, allowing the controller to stay longer on the same page."
It's only PC2-5300 and not really fast timings, but maybe its an indicator of what is to come. I'm guessing that by the time AMD's Barcelona is out, it'll be running at faster speeds and Intel and nVidia's memory controllers will be supporting it too....
Interesting stuff.
