I've used 2 DFIs.
The 1st was a NF4 LP Ultra-D.
That board was a pain in the arse the first 2 months i got it.
However, after some tweaking, a lot of reading from forums, it works like a charm and i started falling in love with it.
My 2nd DFI is Ah_Khoo's ex DFI.
I can say, so far this is the easiest plug and play board i've used.
Plugged in everything, booted 3.2Ghz on 1st boot.
Very minor ram tweaking. If i have HPR i think no tweaking needed at all.
The board had been superbly stable as of today, i've never crashed even once running on 3.2Ghz...
So basically, it differs from Models. The LP 590 SLI seems to be a problematic one i heard. There were quite many issues with it.
Btw, if you want a nice proc, check out garage, Xixo's ex F3 is now on sale.
Better grab it fast, that should outperform any average BEs when it comes to OC.
i saw my name there.. morning all
