    Sorry, you're right. I meant a 45W max TDP rating for BE-2400 at 2.3G whilst 4850e 2.5G is a same TDP lower binned chip with 200MHz more than BE-2400, yes.
    E7200 does not have hardware virtualisation support (wish, they'd manage to make this more transparent via the product name).
    Skimmed over an Computer Base review and the power consumption in idle seems to be onpar with an downclocked X26000 at 2.2GHz. That downclocked X2-6000 still winns price/preformance wise.

    Clock frequency: 	2.1GHz
    L1 Cache: 64K instructions + 64K data per core
    L2 Cache: 512 KB per core
    Production: 65nm Brisbane, Fab 30 and 36
    Quantity of transistors: 221 million
    Core area: 118 mm²
    Default voltage (Vcore): 1.15-1.20v
    Max TDP: 45W
    Max current consumption: 36.5A
    Max Tcase temperature: From 61°C to 78°C
    Min CnQ Frequency: 1.0GHz
    Min CnQ Voltage : 1.10v
    Max CnQ Current: 22.5A
    Max CnQ TDP: 27.7W 
    
    vs.
    
    Processor: AMD Athlon X2 4850e
    Clock frequency: 	2.5GHz
    L1 Cache: 64K instructions + 64K data per core
    L2 Cache: 512 KB per core
    Production: 65nm Brisbane, Fab 36 Dresden on 300mm wafers
    Quantity of transistors: 221 million
    Core area: 118 mm²
    Default voltage (Vcore): 1.15/1.20/1.25v
    Max TDP: 45 W
    Max current consumption: 36.5 A
    Max Tcase temperature: 78°C
    Min CnQ Frequency: 1.0GHz
    Min CnQ Voltage : 1.0v
    Max CnQ Current: 15.1A
    Max CnQ TDP: 18.1W
    How the above differ from the X2 3800+ 2.0GHz 1.025-1.075v EE SFF 35W model is, it needed 1.5v for ~2.6G.
    I'll disconnect the CD drive don't worry But yeah, it'll be good to compare ocne again.

    Those where my results all passed 5-15mins prime so the final stable voltages might be ~0.05V higher.
    Do you own an 78GB raptor? I might pick an WD 500GP.

These results are CnQ and CE1 results and it shows a very likely possible error in low end results I've seen and not been able to repeat in some online reviews for a while now. P-Tuner IME is a very accurate DCA tool at low wattages on each rail.
    My dmm can be used to measure amps but the docs say it must be measured without voltage applied.
    I compared 4pin vs 8pin rails. With 8pin rails P-Tuner readings are very accurate dV=~0.01V. With the 4pin rail P-Tuner readed an ~0.08V higher value.
    What really puzzled me was HWmonitor, 12V2 shows higher values than in P-Tuner and 12V4 (unused) seems to be used.

    Thanks for the phoronix link. Comparing an 1.8GHz xeon with the opterons is abit suboptimal but I like their work on the benchmark package.
