Hi ZGR,
I have the 2.3 ghz 2012 classic mac pro with the 512mb 650m. I cannot overclock whatsoever with MSI or EVGA, but with nvidiaInspector I can force P5 state and overclock the core. I cannot clock the memory any higher than 2000mhz. I have read other people with the same issues so I guess there must be a difference between the two models aside from just the size of the memory. Just to be clear, can you please tell me how you overclock yours? Is it as simple as just opening up MSI afterburner and moving the sliders? On mine it seems to stay in P1 normally until I force P5. In P1(the dynamic clocking mode) I cannot make any adjustments. In P5 I can OC the core to a constant rate of choice but only set the memory up to 2000mhz. I do not experience any throttling due to power constrains or heat as you have described aside from an occasional time or two where it drops to 750mhz for a sec.
Thanks
