2.0GHz: 11.9 GB/s
2.2GHz: 35.8 GB/s
2.4GHz: 12.5 GB/s
2.6GHz: 36.8 GB/s

That's a big difference ...
Looks like a bug. And I guess the will be some interesting results if you starts playing with the core frequency as well. Could it be problems with the sync?

And the whole write through idea looks like crap to me. What is the advantage? I think I can see some drawbacks.
