295x2 not detected by OpenCL on ubuntu 15.04

Ubuntu server 15.04 with Catalyst 15.5 drivers and AMD APP SDK 3.0 Beta for 64-bit Linux.

 

Two cards plugged in: 270x and 295x2.  lspci shows both cards, as does amdconfig, but OpenCL only detects the 270x.

 

The OpenCL program I'm developing works great on the 270x, so drivers definitely work for that card.

 

Anyone know how to make OpenCL detect the 295x2?
