4890 screen flickers when overdrive is enabled

its to do with the atiplay settings some cards experiance it most dont.
to fix it make sure your 3d memory overclock matches your 2d memory speeds or make sure your 2d memory speeds match your 3d memory speeds.
as 2d memory voltages stay the same no matter if there in 2d or 3d.
you need a bios editor RBE to fix the issue.
If you want me to fix it for you email me your maximum memory clock speeds and bios. email in trust ect ect.

All that just went wooosh over my head lol.
It's a brand new card and I already had a random problem of it not showing a output in 2 rigs, sent it to OcUK who found no problem with it and when I put it back in my machine it worked fine.
But is editing the bios going to void my warranty? If so I will send it back and get a refund because I can't happily keep a card knowing it has a fault which I can fix by voiding the warranty.

I notice that when I enable Overdrive, the core clock, memory clock, VDDC Current and ??? current constantly dip when the screen flickers. The graphs look like:
_-_-_-_-_-_-_-_-_- with each change the screen flickers, which is about once every 2 seconds.

Have you checked for physical defects on the card? Tried flashing the BIOS to the latest version?
