Hey folks,
I have 2 servers running oclHashCat, both are identical and I thought I set them up identically. When I run oclhashcat in benchmark mode both machines seem to see both devices (each server has 2 x R9 270x's), but one only hashes at half the rate, as if only one card is actually being utilized:
Any thoughts on how to investigate why box1 is hashing so much slower then box2? I thought I installed them both identically, pretty much to the letter of the linux server howto: https://hashcat.net/wiki/doku.php?id=linux_server_howto
Many thanks, let me know what other info I might provide.
