what model number, speed, voltage, timings and configuration is you patriot viper ram?
These are the models of patriot ram up to 16GB in 2 or 4 slots on the Asus Maximus V Formula QVL:
PXD38G1866ELK 2x4GB 1.65v 9,11,9,27 or 9,9,9,24
PGD316G1600ELK 2x8GB 1.65v
PGD38G1600ELK 2x4GB 1.65v 9,9,9,24
PVV38G1600LLK 2x4GB 1.65v 8,9,9,24
PG38G1333EL 8GB 1.5
PGD316G1333ELK 2x8GB 1.5v 9,9,9,24
I'm thinking that if your ram isn't on Asus' QVL, it might not post.
