So here's a thing. If I try to OC my PNY 1070 outside of SLI and outside of core spec, it freezes my computer. I thought the method of OC (MSI Afterburner) was at fault so I tried NVInspector. No dice.
I took it apart to replace the thermal material and clean the fans - and whaddya know. There are two points on the rear of the board that control overclock protection and overvolting protection. Connecting the solder points seemed to fix my problem - I ran Superposition at +400 memory and about +50 on core in addition to the +100 of my modded BIOS.
Unfortunately my temperatures drove the clocks down, but I'm getting a liquid cooler for it soon so I can get to the 2100MHz my Founder's Edition card managed to achieve.
Neither this PNY card nor the EVGA card that I sold for $850 could touch my old Founder's Edition until it exploded.
Here's some images of the OC/OVP switches on the card. It also has contacts for a multimeter to monitor voltage on vCore, memory, and the GPU clock generator (PLL)!
I'm not going to submit a score for this card until my water cooling comes in - but when it does I'm coming you, SinxarKnights.
