Crossfire Question/Help

[knight_40k]

So I recently pulled 2 4870s from different computers and Crossfire'd them in one system. They are both Asus 1GB Dark Knight edition cards. Since doing this the fans seem to be spinning at full blast all the time, even at start up. They never did this before. AMD overdrive shows that the 2 cards are operating at different clock speeds.

 

Card #1 graph shows GPU clock @ 500Mhz, Memory clock @ 900Mhz

Card #2 graph shows GPU clock @ 750Mhz, Memory clock @ 900Mhz

 

Below the graph there is a sliding bar for each Mem and GPU. The starting numbers are the same for both cards but the end numbers are different.

 

Card #1's bar shows GPU @ 500-850 (750 in the box beside), Memory bar is 900-1150 (900 in box)

Card #2's bar shows GPU @ 500-900 (750 in the box beside), Memory bar is 900-1300 (900 in box)

 

Is this normal?

 

System using is Crosshair V, FX8350, 8GB 1333, Corsair TX750 V2, Antec DF30 (2 front 120 fan, 1 rear 120, 1 top 140, 1 side 120)

Try using MSI Afterburner and set up your own smart fan profile. It should override to an acceptable level ramping the fans up when temp hits thresholds.
