I want to run the blend test because I am trying to check the ram More about : prime95 geofelt a c 208 à CPUs a c 86 K Overclocking June 23, 2012 6:16:48 PM Best way to test ram is to use memtest86+. Run it for a couple of full passes with NO errors. For prime95, run it untill the cpu temperature reaches it's maximum, and then perhaps an hour should be sufficient. Specify rounding checking. Again. you should get NO errors. I really don't think you can benefit from much longer runs. dragonsamus a b à CPUs a b K Overclocking June 24, 2012 11:35:29 PM When overclocking my CPU I tested by running Prime95 for an hour on torture test. You can run longer but an hour should be fine. :-) Related resources 3770k over heating Prime95 - Forum 3570k prime95 error need help - Forum Plss help with prime95 error - Forum Prime95 temps with 3570k at 4.4 ghz help - Forum Battlefield 3 crashes my computer but Prime95 does not? - Forum Can't find your answer ?
