I've been attempting to overclock my EVGA 1070 SC (Both Afterburner and X), manually and through setting curves. I had heard setting curves gave you better clocks though, so I thought after I found a good manual clock I'd switch to a curve and see if I could get a better one.
 
Well... what's going on? Something seems off for sure.
 
Stock
  
 
+175/+550 Manual
 
 
2217/+550 Boost
 
2240/+550 Boost
 
2443/+550 Boost
 
Yeah. You heard that last one correctly. X (GPU Z was confirming the readings) was reporting a stable 2443 throughout the entire benchmark, without dropping once at 1.093v. Fans were blasted up to max to keep the temps at 45c.
Of interest is how while the boosted scores are lower than the manual clock, the minimum FPS goes up with each one. [This]( is basically what the boost settings in X looks like (the extra before 1.093 was me trying to get the thing to crash).
 
So it is quite obvious that something is being reported wrong, as the manual clock goes quite a bit higher in Heaven and crashes on the core long before GPU boost does.
 
I've got no ideas on what the hell is going on. It's like I've missed something but I'm unsure as to what, exactly. I'm using the latest version of Precision X (downloaded it today after trying Afterburner), and setting the offset with GPU Boost to the same as the manual offset (+175) resulted in lesser performance compared to the manual offset.

    Looks similar to what I get when going from 2202MHz to a little higher - it drops the scores/FPS. My 1080 ACX 3.0 (yeah, base model) can only bench up to ~2240MHz with some success under water and <35C temps.
     
    I'm not totally sure, but for me I think it is still a stability issue - probably power starved. Your GPU under LN2 with a modified power delivery board would probably be freaking insane.
     
    Edit - if you haven't already, try removing any VRAM overclock, or even underclock the VRAM, to get the GPU more power to see if that helps any.

    Hi,
     
    So I did as you suggested and here's what we got:
     
    2493/+0
     
    From what it looks like, removing memory clocks is just decreasing the FPS further - nothing I can do will bring it close to the 57 that a manual clock scored. I also tried running it with no clock at a boost +175 offset (to match 2164 where manual is stable) and it was lower too.
     
    This is what GPUZ tells me when doing this, btw:

    The core is running awfully warm to be running clocks that high.  I've found through the several Pascal cards that I've owned, that anything above 25c or so doesn't run well at 2200+.  Lower temps, and you'll very, VERY likely see an increase in performance....and may be able to lower voltage, to decrease the power limit throttling.  That's certainly not helping your scores, either.

    Clocks that high, certainly seem like a bug to me.

    Yeah, I am figuring this is some kind of bug, I just wish I knew where it was coming from (updated drivers already, etc) so that I can just GPUBoost normally and have the acclaimed better to manual clock performance I'm supposed to get.

    aye, your card wouldn't be doing 2480 (nearly 2500) at 45c.
     
    Even kingpin needed LN2 to get a 1080 to 2500 odds.
     
    You running a cross-flashed BIOS?

    Oh, what tool are you using to monitor the GPU frequency? Heaven/Valley? (they're way off)

    No flashed BIOS
     
    And I was monitoring the frequency through Precision X - this was also confirmed running the GTA V benchmark. Even played for a bit with it running at a reported near 2.5.
