+135% PT / +130 Core / +183 Memory = 1045 Core 1594 Memory 1150 Boost
For myself, +183 Memory offset gives me an even 204.0 Bandwidth. I found I can do +200 Memory offset but it's border line stable, where I'd be OK benching but not many hours of BF3 multiplayer. My +200 is a 100 MHz Memory over clock. I backed off memory just a tad and looks like I've found the memory sweet spot, for my card anyway, gaming and benching stable and able to keep the Core +130 offset.
I think I've met my Core clock limit as well at +130. Funny thing was that I backed off the Core to +124 to give me an even 133.0 Texture Fillrate and ended up with a better score in a performance 3DMark11 score. I can't see why unless being just a tad more stable gave a better Core boost as end result.
My card stacks up to some
680's SLI / 7970's Crossfire performance from what I'm seeing on average give or take which is pretty darn good for a dual GPU to accomplish.
You've got some great benches I've noticed Stateless. CheeseMaster as well. Very nice.
Well, I only have 1 690 now. I sold the 2nd one off due to really not needing it due to the resolution I play at (1080p). I did test the 2 cards individually and they both did not break past +130 offset on their own. In SLI they together would top out at +120 which is typical when you SLI 2 cards together, usually your max overclock is a little less that individual cards. I am noticing more and more people around the +130 mark on average with some being lucky to break that barrier.
For a Single PCB with 2 GPU's that is pretty dang incredible. At +120 offset and +200 on memory I have been able to beat out 2x680's in SLI, but not all as it really is about being lucky and getting 2 GPU's that clock very well. But the nice thing about the 690 is the fact that you can get close or match 2x680's in SLI but use less power, less heat and it takes only one slot.
