I am determining my max core and mem and there are two things I remember reading but I cannot find anymore. One is, after you determine the max core and memory, your supposed to lower it down a certain amount to be safe... like 5-10 points or something. Also, how long are you supposed to let the tests run? I don't think I can safely do 10 hours or something like that since I will not be able to watch my computer adn I remember people saying you should keep an eye on it. Also, when do you know when to stop finding? When you get artifacts of course, but what about temperature, should you lower it at a certain temp? I am using a 9800 xt with ati silencer 3. I appreciate the help.
