I have just put a Titan Black into my computer for it's double precision capabilities but it is slower than the HD 7970 that was there before. I have enabled double precision in the driver.
It is only showing 4GB of Vram in Boinc when it has 6GB.
I am running Win 7 x64
Any help would be appreciated

My guess is that Titan Black shows its full strength only with CUDA applications.

Hi Vortac,
Yes I think you are right, not to worry it is still a good card.
Thanks

The key is to run seven (7) task concurrently since approximately 14% of the TITAN GPU core is used for one MW task. Running seven (7) at the same time with DP enabled gets you around 99% GPU utilization and then will the card start to match or outperform a 7970 or 280x card.

Hi RaymondFO*
My apologies for not responding sooner I was not aware of any further response to my post. You are absolutely correct with 7 which I discovered by trial and error and are how they have been running for a while. Thank you for your input it is appreciated.
