ok so i just bricked my gecube 3850 by setting vcore to 1.42v

it worked ok for a while, but then it started artefacting so I removed the mod, then it started artefacting at stock, and now it even artefacts at 300mhz...

funny thing is though, on one occasion it seemed to work fine at stock clocks after all these problems, even getting through 20 minutes atitool artefact testing and a crysis benchmark at high settings with 4xaa. Leads me to believe it may be reversible damage, but who knows... :S

remember kids, all mods are done at your own risk
