The freeNAS forum actually had me run that and the highest speeds i was seeing was 365. So its something with the settings of that card. They also sent me a list of Tunables with numbers to try. spent about an hour playing with those numbers and every change made it worse.
Another guy on the forum suggested i try the other slot so when i get home tonight i will try that. He thinks even though HP says the 8x is wired as such it just may be a low end 8x and the band with may not be there. The only reason that makes sense is that the ASUS card is a 4x and it worked perfectly. This card is an 8x so it may just need more than that 8x port can put out.
Tonight i will hopefully have better news after i make this change.
This server didn’t come with the HP disk that everyone talks about using and i have yet to find an iso image that i can put on a flash drive. But freeNas sees all the drives and writes to them without a problem.
