Here's my journey.1. Setup
I started off after a DDU uninstall and complete clean install of just the newest driver and PhysX without changing anything in NVCP.
I ran a Firestrike benchmark without touching a thing right after.
Stock Firestrike Graphics Score = 187312. Core Overclocking
I installed MSI AB and maxed the power and temp limits (111%/92c) and increased the core clock by +10mhz each successful run.
I stopped at +110mhz where it usually crashed before a run could finish, and settled at +100mhz as there was no artifacting or any visual weirdness, just program crashes at +110mhz.
With only temp and power limit maxed and a core of +100mhz I got a Firestrike Graphics Score of 19348
With the exact same settings but the fan at 100% the whole run I got a graphics score of 19498

3. Memory Overclocking
With an established weak +100mhz core increase that stays under 2000mhz 99% of the time under load... I moved onto memory.
Increased in increments of 100mhz it wasn't until +700mhz that visual artifacting began. It persisted at +650mhz so I settled on +600mhz.
With this my Firestrike Graphics Score ended up at 20600

4. The Frustration
I'm disappointed that my core is rarely ever over 2000mhz while others are getting 2100mhz+ with ease, and graphics scores of 21500+ while I'm stuck around 20500.
It isn't even 100% stable at 2000mhz either, it crashed once after hours of running. It looks like I'll probably have to lower things even further if I have issues while gaming, memory included.
What makes no sense is how the core clock causes crashes, there are no signs of instability visually or from GPU-Z like you would expect.
When the memory was reaching its OC limits, visual errors appeared before 3DMark or anything else crashed, you would expect this of the core as well.
When the core crashes, the driver never crashes, nothing spikes or drops prior to it happening in GPU-Z, there are no artifacts or visual issues. It's like something pulls the plug.
More frustration comes from the fact that increasing core voltage does nothing to help
. It gives 0 overclocking headroom and in fact seems to add instability to your overclock.
Running these clocks that cause 3DMark to hard crash in Battlefield 4 cause BF4 to completely lock up and freeze after a short while. Again, no artifacts or any visual errors of any kind.
No display driver crashes, no visual instability, no GPU-Z drops or spikes prior to crashing, it's as if it just doesn't get enough power for a split second, though the voltage does not drop.
The way the core becomes unstable and crashes is sudden and weird, I feel there's something wrong with the BIOS possibly causing this limit.
There should be other signs of instability somewhere, this is abnormal and abrupt.
Here are GPU-Z results of a crash with the voltage maxed out. Besides the maxed core voltage the settings are identical from Part 2 Core Overclocking, the core is still only +100mhz but the increased voltage gave a higher max core. The max core was not what GPU-Z recorded right before the crash, it was at just 2012mhz.
Increasing core voltage from 1.0620 to 1.0930 makes it crash more, and doesn't allow for any more mhz on the core clock. If I increase my core voltage, I have to lower my core clock to maintain stability

So I'm not too happy. My GTX 970 had a Firestrike Graphics Score of 14318 for what it's worth with this same system. Top tier 970 to bottom tier 1070.
I suppose at the end of the day, 14318 to 20600 is a 43.87% increase, and my stock 1070 score of 18731 to 20600 is a 9.97% increase.
This is assuming I don't have to lower my core clock to +90mhz or less which I may have to which is pathetic, hopefully it will hold up in games since it usually does in Firestrike.
Mem might have to go down to +575/550mhz if I ever see anything weird again but that's still pretty good, better luck than my core OC quite obviously.
If I could have achieved a score of 21750 like some people on 3DMark, that would be a pretty juicy 16% boost over my stock score.
I can't check my ASIC with GPU-Z to see just how bad it is since it's not yet supported, but I'm guessing 65% or less.
Lastly, my fans have been weirdly loud occasionally during RPM changes, they hit some real turbulence or something, vibrations. Hopefully that happens less.
Maybe I will be able to hit 2100mhz core when custom BIOS's are available, which will make it so increasing your core voltage ACTUALLY HELPS.
That could be useful, having a voltage increase that increases OC headroom and stability instead of ruining it
