Seems everyone's having the same problem with the EP45T-UD3R... i can't get mine to run at 1600 CAS 7, like my ram is rated for. I have a 2x2GB OCZ platinum kit, 1600 CAS 7, 1.9v.

I can get it to boot, but as soon as i run prime blend it fails immediately. No matter what timings, voltage and strap i use, it's all the same...

Now, i started playing with the driving strengths, and these made a huge difference ! set them all to +8, just for the sake, and it made it last 10-20mins on prime blend before fail... quite the difference.
Too bad the board doesn't have the driving strength profiles... it's hard to tune all 8 settings for both channels

Does anyone have any experience with the driving strengths? care to share ?
