An alternative to building a second setup would be for me to pull my Barton out of main rig and put it into test loop. I can get an estimate of K7Burn Watts by measuring delta T across the waterblock and we can just correlate remotely. How to determine Vcore is the same though for different motherboards and systems? I keep meaning to solder a DMM to some motherboard pins...
Oh as an aside I just finished running a quick test of a waterblock to see what W estimates I would get. Results SEEM to be reasonable (C/W values line up predictably with BillA's testing, W estimates mesh well with earlier estimates from MCWChill testing, etc) but are off an ENORMOUS amount from benchtest.com calcs (and presumably radiate). Jim's calculator spits out 113W for a Tbred at 2200MHz 1.85V, while his "88% rule" yields 99W. Not a reflection against Jim or Benchtest or Radiate; it's just the numbers from mfgr are not very reliable for AMD chips I think.
It would be nice to get some complementary techniques running at the same time to get a handle on this but at least in a preliminary fashion I am feeling pretty good about our W estimates over calcs.
