I'm having this stuttering/freezing issue while playing battlefield. I would play for 5 minutes and then it would just lock up on me .I tried resetting my bios, turning off all of my overclocks and reverting to old drivers. Nothing seems to work. Could it be hardware issues. Here are my specs
Amd Phenom II 960t OC to 3.6
Sapphire Amd Radeon 6850 Oc'd to 900/1100
Gskill 4gb 1333 mhz DDr3
no the card is three months old. This has been happening for about the time i started to overclock it past 850mhz on the core clock. Whenever i go upwards of 1100 on the mem clock i black screen. I used the Fur bench Test benchmark and it didnt go over 75 degrees i'm gonna try running again without the overclock. Another thing is that when i go to play source games it freezes up too but not as bad. Is it the Cpu's overclock or the gpu's thats causing the freezing?
No, that just means you didn't overclock properly. As said before it is very highly recommended reading this guide before doing any overclocking. The card might be stable in furmark and any other stress but in some games it will crash. Also overclocking your card will make it unstable so you have to find the stable settings for your card. Every gpu is different, it's a matter of trial and error.
