Highest memory speed reached at acceptable voltages and timings. I did not run any 500+ FSB for simplicity purposes because this article is to help others gain starting stability, above 500 FSB each user would need many specific settings tweaked which cannot be generalized.
I did however, run a few tests at higher speeds then listed below with a set of the 1GB Modules. They (2x1GB) ran up to 1200Mhz without issue using 450 FSB X 2.66D and 500 X 2.40B.
