So im doing some stress testing and want to know from someone who actually knows what theyre doing. When using aida 64 to do stress testing do you need to have cpu and fpu checked when doing the stress test. Even at a 4.6 ghz oc my cpu reaches low 90s when both are checked but when just one or the other is checked temps are fine. Prime 95 temps are great as well but not when cpu and fpu are checked on aida 64. So i guess my question is is it necessary to use both when testing the stability of my overclock
