Anticipating an increase in Vcore, I removed my whole system out of my ghetto case for better airflow/temp. And the Vcore did nothing, zilch, nada. The default Vcore on my card is 1.19v. The cards are GTX280 Zotac AMP and MSI Super OC. Both are already highly oc'ed at 702/1402/1150. I went even to 1.35 but that did nothing. Tried everything in between too. The same, nothing. But the temp improvement from the open air system does improve oc little bit from 712/1456/1332 to 720/1512/1332 at default Vcore.
280 doesn't have much headroom on voltage unless you can keep temps below 50c full load. Wouldn't raise it to more than 1.24-1.25v as the heat is pretty intense, and higher shader clocks at least won't be stable if your core is over 70-75c full load.
