well that totally didn't work for me. GPUs won't even start like that, trying the miner out, but having to put in all the settings again, this nscrypt does seem like pure voodoo like that guy said

I had same problem. GPUs off, you just need 8mb of ram, then all works.
The funny thing is when I'm mining, I look the system memory and I'm just using 1.6 mb, so I dont understand why 4mb not enough.
This BS is pure voodoo

lol
This was my problem too. Using 7950s, no indication my system was using the 4gb it had.... putting in 8gb worked for me. Sweet. So I played with settings a little bit, then left it sit to mine. Done and done.
BUT.... One gpu died so I restarted the system, and now it doesn't work anymore.
