thanks for this, I just got this card and working on getting it past 700 still, have you also tried the sapphire trixx? This allows for adjustments as well and core voltage out of the box, for some reason even though I adjusted the msi afterbuner config I was still unable to adjust the voltage.
this is my current command line
-v 2 -w 256 -k diakgcn -I 9 --temp-target 75 --auto-fan
core at 1155 , memory at 1040.. haven't played with volt adjustments yet.
Have you tweaked your settings lately? Also what driver or sdk are you running..
Haven't messed with the settings lately, although I noticed that workspace 256 preforms the same as 64. I think I may have bumped the voltage a tiny bit. I'm running CCC 13-1 whql. I was using the beta (3?) just fine, but afterburner was driving me bonkers and I uninstalled everything and went with the whql when I reinstalled, mostly because I still had the install file.
I've played with trixx a little, but I wanted to undervolt the memory so I went with afterburner. I still haven't played with undervolting the memory yet though. I was waiting on a yate loon 140mm case fan before I started tweaking again, but it hasn't helped airflow in my case as much as I'd like (I'm running 2 cards on a small MB with bad spacing) so I'm probably going to have to find new 120mm fans for the back to fix the general airflow issues in my case. More money :\
why are you oc'ing your memory ? you're doing litecoins ?
From what I understand its good to keep the memory down under 150 below the gpu... but im still learning a bit..
This is what I've read everywhere for this card too, and when I tried dropping it 160 below the core it produced a lot of HW errors for a few min then crashed the drivers.
