So it appears the card can hit 6608 and be "stable", but it takes an increased TDP as the RR09SS set the draw to 300W in normal and boost mode.
However, this memory OC of 10% only increased my overall 3DMark11 Extreme score by 50 points, so not really worth it.
Also, upon actually looking at all of the test scenes, it appears that while Demo 1 became clean of artifacts, there were some artifacting in Benchmark Test 1, which is not a scene I had ever stared at before. So 6608 is not 100% stable. However, the same scene was artifact free at mem clock 6550. So somewhere between 6550 and 6608 is the breaking point (with these BIOS).
So this is a card which can easily boost up to 1072 core, and OC to 6550 mem. At those values, it is stable and artifact free in every single 3DMark11 scene. That's not too shabby. I haven't browsed the entire Titan Owner's Thread, but it seems most people's memory clock is topping out at around 6400 - 6500. A select few are getting 6600+.
I am beginning to think that maybe I shouldn't RMA the card after all, as the hardware on this card is solid, it's just the stock vBIOS which are crap.
I should point out that these RR09SS BIOS do NOT raise the vcore at all. They simply raise the TDP def and max to 300W instead of 265. I am not sure if mathematically this requires an increase to vcore, but in all of these tests with RR09SS, GPU-Z reports the voltage topping out at 1.162 which is the reference default.
