Seen it at 2.185 MHz for some time but it stabilizes at 2.088 MHz while gaming (GTA V, Witcher 3 and Fallout 4 mostly). This was at stock.
I'm not familiar with the OC of Pascal yet, but did a few quick tries just using the sliders on afterburner. It seems to handle +20 MHz GPU and +50 MHz RAM and that was it. Even the +20 didn't seem stable in the long term. Even with that OC, I couldn't notice any difference in FPS.. maybe +1 FPS in W3.
I'm fairly happy with it tho, never see it below 2 GHz while gaming and it is pretty cool -. As in 57-62C while gaming (in a room with 22C ambient temperature).
The fans are a bit noisier than I expected tho.
My AMP Extreme starts over 2150 (I've seen it like yours reaching 2185) then gets stable at 2126 Mhz with +60 GPU, temps under 70C without maxing fans (32C room temp)
I keep Mem at +100 @ 11k Mhz but it could go higher.
A great deal of lottery going on, in his review Jay could not get his Extreme past 2050 Mhz:
And this guy with an SLI gets 2152Mhz fully stable with +99 GPU:
At the end comparing models is pretty much pointless as one unit will differ greatly from another. But I have to say that I've never seen any reports of a Zotac AMP Extreme not going above 2K Mhz (while I've seen quite a few from other well known brands), so to me buying this model gives you at least a certain peace of mind that you will reach a pretty decent clock. Mine boosted 2077 Mhz out of the box.
Don't mix it up with the AMP version reports btw, I had both models and the AMP runs 20C hotter than the AMP Extreme, it's a complete different cooler.
