Crossfire, one card RAM doesn't clock down when idle

[Met-AL]

First time multi-GPU user here.

I have a pair of 6850 cards on a z68 board in Crossfire.

One of my cards, GPU1, runs considerable warmer and the memory never clocks down when at idle like it should. I have looked all around MSI Afterburner for some setting and found nothing.

Any suggestions?

How many monitors do you use?

I use two, and both are plugged into GPU1

thats why you have the high memory clock.. single display 2D is 137/300(i could be slightly off on the gpu clock) dual/eyefinity 2D is 400/900.

Ahh, gotcha.

So it's normal then. Good to hear.

 

[sirmonkey1985]

yup its normal, if it dropped to the lower single 2D clocks you would get the awesome and wonderful flickering effect due to the ram clock being to low.

Yes as previously stated its normal. You'll get crazy flickering, which gets really annoying.

+1 - the high clock speed was to prevent the display flicker issue (which was much more annoying!)
