More Titan pics :
http://imgur.com/a/dCjaXI have changed the pool : its seems the titan doesn't like clevermining.
So I'am pointing the Titan at my WDC pool and its very stable : 260 MH/s + (underclocked @ 250mhz)
I think it's been established already that multipools don't like the Titan. They can't handle the hash for some reason.
