So what really is faster...3.8GHZ CPU but NB at 2000 or 3000MHZ?

Has anybody tried PCIe Speed Test v0.1 to measure CPU-GPU/GPU-CPU bandwidth from the ATI Stream Power Toys site? Maybe it can help troubleshoot some of these HT Link speed issues. Theres also a forum post on the ATI developer forums about it here: http://forums.amd.com/devforum/messa...VIEWTMP=Linear

Maybe with this, you guys can figure out why we get a slowdown when we push the HT Link speed high.

EDIT: Max speeds at CPU Core@3.2 1.35v, NB@2.4 1.25v, HT Link@1800mhz 1.2v, PCIe@124mhz, HT, NB Chipset@1.1v:
Max CPU -> GPU: 5.484 GB/sec [8388608 bytes]
Max GPU -> CPU: 943.053 MB/sec [1048576 bytes]

HT Link@2200mhz 1.2v:
Max CPU -> GPU: 6.417 GB/sec [8388608 bytes]
Max GPU -> CPU: 952.805 MB/sec [33554432 bytes]

FYI: This is a very stressful test and occasionally causes the ATI GPU driver to restart. We may be able to use it as a stability test as well.
