Well, I currently have a Rampage IV Extreme, 2 galaxy gtx 680 soc in sli, lsi 9265-8i and a creative x-fi titanium hd. I try to upgrade my 680 with the new titans. I install them, one an Asus and the other an EVGA Superclocked. I try it, but system hangs in the lsi boot rom. It never gets to the F/W Initialization. I try removing all the cards and left 1 titan and the lsi, and no luck. Also try the lsi on different slots and the same. If I remove the lsi, system boots fine and titan works. But as soon I put it back it hangs on the lsi. I contact lsi, evga, asus, even adaptec. None of them has a solution. LSI saids they don't check compatibility with videocards, that if changing slots doesn't work that I keep using the 680. Really? C'mon. According to Asus it should work, but they didn't test it. Evga saids something like that, I really don't remmeber exactly now. So, I think to change it with an adaptec 7805 if this solve the problem, but adaptec saids they don't if it can work or not, they didn't test it on rive. So, my next idea was changing the motherboard with a Workstation series, like the Asus P9X79E-WS. Contact presales from Asus, and again, they don't know if it going to work, it can or not. I contact lsi to check with this board, and they don't know either. So, I don't want to spend more than a 500 dollaras for a board to check if it is compatible or not, or worse, spending 600 with a new raid card. So, anyone here have a similar configuration? An lsi raid card with a titan? I have lastest bios from asus and also last firmware from lsi. My guess is a problem with the rom of the card going to the same address of the rom of the titan. Any suggestion?
