So last night I started overclocking my MSI 970 Golden Editions.
At stock voltage the highest stable OC I was able to get was Core: 1514 MHz (+208) and VRAM: 8610 MHz (+400). This gave me an fps of 114.9 in Heaven at 1920x1080 w/ maxed out quality settings, 8x AA, and extreme tessellation.
Turns out the GPU I have in my prime 16x PCI-e slot is the card that is the weakest link in the SLI configuration. It is the card that fails when I push higher. This GPU has an ASIC quality of 67.2% The Second GPU has an ASIC quality of 60.1%... So for people concerned their GPU's post low ASIC scores, don't fret, it's a useless metric. I have yet to pull GPU 1 and see how far GPU 2 can go, but I will jump into that this weekend. At that time I will also host and post some screen caps showing scores/performance to verify these claims.
In the meantime, does it make any sense for me to swap GPU 1 & 2, so that GPU 2 is in my lead 16x PCI-e slot?
