Temp target? That infomation is irrelevent because his cards are under water. Clock speeds? Irrelevant. The cards throttle because of power limitations and heat. Neither were maxed out in that regard so it shouldn't have happened.
Your BIOS combined with his driver has bugs and throttles. That's what the issue is.
First of all, I hadn't run Valley to confirm and yes it is normal for the card to down clock when utilization drops, that is expected and what I assumed was happening initially. That is why I ran it myself to double check. I wasn't aware his cards were under water until he mentioned it. Lastly, if the vbios were the culprit, it would have caused the same behavior on my system as well as others which it clearly doesn't.
In fact, its only now that he mentioned he's using 320.14, none of this was brought up before.
Majin - run both vbios using the 320.14 driver and see what happens. I'm using 314.22.Edited by 5150 Joker - 5/18/13 at 6:31pm
