Silly me
I used an old shortcut, 1.11 is much faster 6.65ms/sec at default clock/fan settings.

looking good, nice =D!

Hi guys for interest here's a couple of results from my Titan:

1.10 - 6.53 Ms/s
1.11 - 7.51 Ms/s
1.11 with both Titan and my older 580 together hits 11.31 Ms/s.

System Info:

• Windows 7 x64 Professional
  i7-3930K 4.4Ghz
  32GB RAM
  EVGA GTX Titan
  EVGA GTX 580 Classified 855Mhz Core

Pretty happy with those results, what I'm really impressed with, is the improvement in 1.11, Good job!

Definitely will add another Titan when I can afford it, it's the quietest card I've owned in years.
If anyone want's me to test out anything else let me know.

Does the renderpower decease when the chip gets really hot?
Thinking of the GPUBoost 2.0 which let the card run fast until it throttles down at a certain degree.
Most people just run a quick 5min benchmark and thats it.

Yes that's how Boost 2.0 works, you can prioritise temps or voltage. However I've run fluid sims for over an hour and the card didn't go above this threshold where it will down clock.
The stock cooling is pretty good, I'll run a long Octane benchmark 16000s and record the boost clock later today.

as a comparison, I just ran the benchmark with my 580 and 690 separately with both 1.1 and 1.11.

1.1
GTX 580 - 3.42
GTX 690 - 5.95

1.11
GTX 580 - 3.55
GTX 690 - 6.4

Compared to the Titans 6.53 for 1.1 and 7.51 for 1.11, the Titan is showing better performance than the 690 (Also, it has a bigger speed increase in 1.11 than the other cards).
This is making me wish I waited to buy my 690 and got the Titan instead.

Yes, it seems Titan was made for this sort of workload, you'll still get a good price for the 690 btw, it's the top nvidia card in all the gaming benches.

Bit off topic, does anyone have a K20X at hand to compare? I'd be curious to see if Nvidia have protected the Teslas with their drivers or the like. I know OpenCL is broken in the current Titan drivers (Photoshop crashes a lot...), but they're supposed to be working on a fix.

What is the max voltage for titan ? Can you show the "voltage and tweaks" screenshot?

Wow, 7.51 Ms/s is huge.
Maybe a bit of a stupid question but where does the Ms/s stand for?
