Is your setup still working well @ 1.075v, 1350 core, 1425 mem? Nothing has melted?
I have the 4gb Maxwell. With EVGA Precision it runs at 1.12v under load no matter what I do with voltage even if I keep at stock .868v. Can increase to 1.18v. Kept at stock which again ends up being 1.12v. Other numbers are 1155 and 1420. No modded bios. The pixel and texture filtrates and bandwidth also increase. Settings won't stick with MSI Afterburner. I miss not having a CPU temperature readout.
Edit: The GPUZ reading is now constant at .868v-1.18v with benchmark running in background. Don't know if GPUZ sensors are more accurate than EVGA OSD or maybe when benchmark is in foreground it is a different voltage result.
