Also, I finally took your advice and went down to 1400mhz and 2135. I found I needed about 10mv more for stabe after 16.9.1/16.9.2 and my stable memory clock went way down. 2135 is the max mem on my 2nd card so I might as well run that. Could be degradation problem or it could be a driver thing. I'm not sure why stable settings are no longer stable. Not sure it matters. 1400 is stable. I ordered the block for my 2nd card and will put it in next week. We'll have very similar configurations/speeds so thanks for the benches.
I am glad the information was useful - About the FPS, I forget to check your time spy, was time ago - And It's logical have a few FPS less taking in mind I have 0.5 ghz less - It's clear still the freq it's more important than the cores but im sure like you this going to be more reduced with the time, and improve more the use of other cores, like in Vulkan for example.-
About the Mem freq, I discover something you can try... Less voltage you put, more memory freq you can get... don't know what the hell happends - But the story was when I discover this "insulate" problem in the GPU, I start the overclock again from 0 was very quick we now have the experience, now the drivers are more mature, and all that stuff.-
I get 1390 mhz core (may be 1400 mhz don't try really not time this week) with a real 1.81/85v - In the past I use 1.20/1.22 real voltage, don't know why I use so many, I was doing the things wrong - But anyway, with that high voltage The max mem freq I get was 2135 mhz without errors - But now I get 2160 mhz without errors and that it's a improvement - Of course from 1.21v to 1.81v it's a HUGE difference in temp's in GPU and VRM - So check with 1400 mhz - that's my recommended max sweet point of this video card, and the less voltage you can get, try with 1.75v real (thats 1.85v in GPU Tweak II) and test with Unigine Heaven or Valley (for crossfire) then for stability general use Firestrike (not neccesary ultra) If pass OK with 2135 mhz of Mem, use Metro Last Light and start to rise the Mem I am very sure if you are using less than real 1.85v are going to be able to get 2150/2160 mhz of ram freq.-
Another thing to take in mind be carereful with the CrossFireX and the voltage of the second card, don't know why, but here in my PC the second card by default its detected in the stage 7 with less voltage than the primary (I talk about this but I repeat) the problem with this it's you are going to sync the two video card in any overclocking software but the second will have less voltage in my case the difference it's 50mV a lot really.-
I have constant crashes with the CrossFireX then I see that problem - Remove the Sync option in the GPU Tweak II and manually add 50mv to the value of the primary card voltage in the second one for example my primary it's in 1.212 (real 1.81/85v) and the second one 1.262v (real 1.81/85v) that's because from default have a difference of 50mv , and problem solved perfect voltage in two video cards.-
