Dodge - yes, I had indeed noticed he had a nice OC going for a
XP1600 system, although not untypical of the later steppings in wc systems. And yes, I agree that it is good to see testing done at other than default speeds/power loads.
Don't take what I said the wrong way, I am
NOT degrading his testing. Heck,
his full test data and methods aren't even published yet

When they are, they might very well contain
some of the missing data. However, my general comments regarding good testing methods and results for wc systems stands.
Simply consider what I stated as a precautionary note regarding making
general assumptions about the relative merits of one widget over another based upon a test done within narrow parameters and/or with incomplete data.
Now if we can just get Joe to use higher flow rates (like in the 300gph range) for his next waterblock roundup
Xel - it really depends on the stepping of the XP1600 used. Remember that the only difference between an XP2000 and an XP1600 of the later steppings is which bridges are laser cut and the testing done. Usually the bottom end of the speed bins are simply filled with what is left after the other bins have met their quota. As a result, the "true" OC in this case might be more in the 10% range

As I said, a nice OC, but not earth shattering
