I manually used RBE to mod the BIOS and disable powerplay. I set the card to run at permanent clocks, thus conventional OC software such as afterburner wouldn't work for overclocking. I set the card to run at a constant 835/1250Mhz @ 1.125v. However, whenever i try to set a higher voltage, say 1.17-1.2v and set the clocks to 880/1280Mhz using RBE, the card crashes while on Furmark. What am i doing wrong? Is there another way to get stable higher voltages. What's the highest safe, stable voltage i could run the card at? Any help appreciated
You are not crossfiring 2 cards or more, it's redundant to set the 2D=3D clocks. Editing the 2D clocks are not exactly disabling the ULPS.
You can try to overclock the card using Sapphire Trixx to find your stable OC for core/memory and the voltage to sustain it. Later, if you wish to edit the BIOS with the OC settings, that's perfectly fine. But after editing the BIOS then run the stability test is totally the other way around than it should.
The safe voltage and core and memory settings depend on your full load temperature on stock air cooler. I'd say 70-75°C is safe.
