Help with a CROSSFIRE X board

post #1 of 9
Thread Starter 
I was just interested in the crossfire x mobos. I hear they are much cheaper than the 780/790i nvidia boards but I wasnt sure what boards they would be. Do you guys know of some good crossfire x motherboards that are reasonably priced and would be sufficient for 2 4870's or future 4870x2's? Thank you!.

P35 is a good crossfire motherboard. If you want something with a bit more power X38 is a good way to go. I love my asus p5k deluxe (p35). it's a solid overclocker and has a bunch of nice features (really like the built in wifi).

X38 or X48 for CrossfireX because it gives you two full 16x PCIE slots.

The P35 boards have a PCIE x16 and x4 slot (except the ASUS Blitz). But the X38 and X48 motherboards are both PCIE 2.0 and full x16 to both PCIE. They are not going to be that much cheaper then the 780i or 790i boards. But the ASUS P5E, Maximus Formula (which can be converted to a Rampage with bios flash) and the x48 Rampage Formula are great boards. ASUS also has DDR3 X38 and X48 boards if you want to go that route. Gigabyte has some great boards as well. they have an X38 DS4 and DS6 board, as well as X48 versions.

Basically the X48 is a higher binned X38 chipset, but they are identical physically. The real difference is in the bios options they are programmed with.

Try flashing the Maximus Formula to the Rampage. You will get a lot of ram tweaking options in the bios which will boost the ram's performance matching DDR3.
