Trying to get Claymore's miner working on my test rig, but cannot get more than 2.6MH out of a 390x.  Any help would be appreciated.

Rig:
Ubuntu 15.10
i7 4790k
16GB Ram
Asus 390x



config.txt:

-epool eth-us2.dwarfpool.com:8008
-ewal XXXXXXX
-dpool http://dcr.suprnova.cc:9111
-dwal plggy.R9390X
-dpsw x
(tried changing intensity and other settings with little change in hashrate)


start-up script:
#!/usr/bin/env bash

export GPU_SINGLE_ALLOC_PERCENT=100
export GPU_MAX_ALLOC_PERCENT=100
export GPU_FORCE_64BIT_PTR=0
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1

echo "Starting Claymore"
./ethdcrminer64

Aticonfig shows 100% load but card stays cool and hashrate low.  With ethminer I am around 30MHs with this card.
