    Cool SLI comparison between 790i Ultra and Rampage Extreme

    Since there´s a SLI hack that make it possible to run SLI on a non Nvidia chipset board (such as P35, P45, X38 and X48 for an example) I thought it might be interesting to see if there´s any different between a native SLI board and a SLI hacked board.

    The choice fell on the 790i Ultra and the Rampage Extreme.


    Test setup

    Code:
    Motherboard:	XFX 790i Ultra / Asus Rampage Extreme
Chipset Driver:	15.51 / 9.1.1.1020
CPU:		E8600
Memory:		2x2 OCZ Platinum LV PC3-12800 1600C7
Videocards:	XFX 9800GTX Black Edition
Video Driver:	191.07
Hard Disk:	WD Caviar Black 500Gb
Monitor:  	Samsung Syncmaster 2243BW @ 1680x1050
OS:		Windows 7 RC 64-bit

    The speed for the CPU and memory was set as followed

    790i Ultra 400 x 10 4,0GHz / 1600 777 21 1T tRC 30
    Rampage Extreme 400 x 10 4,0GHz / 1600 777 21 1N tRD 5 Strong (strap 200)


    Let the test start

    Okey, that was it guys, not much of a different, I call it a draw, what´s your opinion.

    looks like minfps is actually worse on the 790, at least in farcr2?
    havent looked at all the results... you dont happen to have a spreadsheet with the results by any chance?

    very nice tests, thx for sharing

    Very interesting observations, thanks for posting!
    I am surprised that REX isn't always better, and I was pretty sure it would be!

    Great stuff Ghostleader...

    Why would the REX be better as he needed to keep all timings and co in equality with the 790i. FSB clocks are too low to make any difference.

    Where the REX shines for benchers is the way it can push the FSB way over 600FSB... Try that on 790i , For me it's even is a more reliable setup for 24/7 than any Nvidia chipset till now will ever be... at 550FSB daily , no biggie here

    Would be nice to see a comparison at 500FSB too... good job old man I bet the REX starts to pull ahead there
    Question : Why do some overclockers switch into d*ckmode when money is involved

    Remark : They call me Pro Asus Saaya yupp, I agree
