Hi philsmd, I went to the same result also with my pool knowledge of hashcat 
Trying to use both the GPU I divided the workload, used two sessions and -d1 and -d2 and... got "Insufficient Memory" error on the second instance.
So I've increased RAM memory to 4GB and now it works as expected
I'm in a really "strange" (uncommon) configurarion..
The two GPU are in my datacenter colocation, the server I'm using is doing a lot of "experimental" things, so I'm using virtualization! (vmware ESXi 6.0)
I know that GPU passthrough is not supported and I wasn't that easy to make it work, but it works!
In this way the RAM upgrade from 2 to 4GB was really easy
Thank you for your assistence, If it could make you smile I've recovered the secret used to sign cookies on the target application
rockyou.txt + best64.rule = LOL ! (12 chars lenght)
Have a nice day, thank you so much
Paolo
