Hi.
I think HP is somehow overriding the vBIOS. No matter what, i was not able to go over the +135MHz limit on core. I've modded the vBios with Kepler Bios Tweaker 1.27. It changes the default boost but the gpu is stuck at 788MHz anyway. I've tried NvidiaInspector. Forcing the PState P5 doesn't work. Limiting to P5 seems to work but changing the core freq doesn't do anything. I'm desperate because i know there's a lot to gain. With the memory at 2400MHz (+1000) it never exceeds 70C.
