For reference purposes, this card's Steel Nomad score with stock settings is 5228. With the Nvidia app auto-tuning, 5370.
MSI Afterburner settings:
+400mhz (3250mhz) core clock flattened at 1.035v and onward
+3000 mhz memory clock
+100% core voltage
+110% power limit (the max for this model)
Doesn't like exceeding 3300mhz or 1.04v from what I've seen. Anything over +400mhz on the core clock and it gets upset fast. Power peaks at 280W. 64C average temp during Steel Nomad, 75C during Time Spy. Benchmark stable at 3250mhz, but I run it @ 3200mhz for gaming and stability. CPU is a Ryzen 7 5700X3D with a -30 CO on all cores.
Please feel free to share your 5070 undervolting/underclocking results here, would love to see how this card stacks up to others (especially those with a 120% power limit)!
