Powercolor 4870 1gb pcs+ problem with 8.12

[invazn]

Hi anyone whom is using this card with 8.12 having to downclock their memory to 900 in order to prevent flickering on screen? If so, are there any remedies?

Based on what I see around here, 8.12 is loaded with problems. I'm using 8.11 for now.

I actually moved back from 8.12 to 8.10 from that very reason, it's riddled with problems!

The flickering you get when changing memory frequencies with the HD4870 occurs with all the compatible Catalyst drivers (8.6 Beta through 8.12 Final).

ATI's implementation of GDDR5 memory and overaggresive PowerPlay state changing is the cause of this.

Best bet is to just lock in your GPU/MEM frequencies for whatever state you're in, using ATT, Rivatuner, etc. You'll only get one flickering effect when locking/changing states this way.

Yes but problem is, I am unable to lock it I tried using rivatuner, and ATI poewrplay over rides it... I even tried reverting back to 8.11 and using driver sweeper as well but to no avail... Should I try ATI Tray Tools too?

ATI Tray tools works like a dream for my 4870. Try it out.
