Benchmarks I
With due respect to performance at stock speeds, the single most important question that presents itself is whether the AI7, for all its BIOS bells and whistles, performs along the lines of a PAT-enabled Springdale motherboard. The answer to that question will dictate performance.
Now given that the AI7 and IC7 (Canterwood) run at almost the same frequency and have identical performance-related BIOS settings, we can surmise that the the AI7 is the recepient of some form of memory accleration technology. A non-PAT-like BIOS would exhibit scores far closer to the 4000MB/s mark.

Performance Acceleration Technology lowers the latency between CPU and memory, using optimised pathways. Here, clearly, there's not much in it.

The Athlon 64 3200+ / ABIT K8V-MAX3 combination does amazingly well from supposedly limited bandwdith and 'only' 2GHz clock speed.
