I got my Power Colour AX7970 yesterday and i wanted to do my first overclock so i read up everything did my research and gave it a go. My problem now is that i dont know why screen is freezing, I can still hear sounds from teamspeak etc but screen is frozen.
Current Settings
Core Voltage 1.2
Power Limit 20%
Core Clock 1.120
Memory Clock 1470
Fans auto.

I have run Heaven with everyone on ultra with no issues at all. My screen only freezes after 2-3 rounds of BF4. My temps are sitting at 60-65

Thanks

Go back to stock. confirm you didnt do any permanent damage. start the process over much less aggressively, and make sure you adjust each setting on its own first, then combine the settings together when you know each one is stable.

i have gone back to stock and everything works perfectly at 45 degrees max. i have been doing incriments of 20 mhz on the core clock. but i can only do incriments of 0.06 of voltage i cant do any less is that normal?

have you been toggling each one independently as to isolate what is the cause of the problem? maybe the memory clock is too high

ok so i have started from the beginning and seems to be going pretty well.
Currently sitting at 1.22 v and 1515 memory clock havent touched core clock as of yet temps at around 50 with stock fan setttings. But i am wondering of the voltage is too high for that current clock?

another quick question when im doing the core and memory clock do i update the memory voltage and the core voltage or just the core??

Memory and core will both need voltage bumps. In my experience I haven't been able to OC the gpu memory at all..I might try again but thought I messed up my card once until I restarted. Screen went orange and lines and was not pretty lol. I'm gonna try again today as I don't get much fpS increase w just the core clock alone. 1000 MHz stock at 1130 MHz core now.
