I am new to overclocking and likewise new to using prime95. i was wondering if someone could explain a little more on how to use prime95 with a core i7. which stress test do i want to run? blend? also how long should i run for (i have been hearing about 12-24 hours). if prime95 fails, the lights turn to red by the worker numbers correct? otherwise if everything is green, i assume it is all working properly? i plan on doing a test using real temp 3.0 and cpu-z , can i do anything else on my computer or have any other applications running while im running prime95?
