Aida64 Vs prime95 when overclocking?

Recommended Posts

Posted · Original PosterOP

Hey guyz.

Sorry for my bad english..

 

i have a x58 asus  p6t mobo with x5670 on it.. my cooler is cooler master masterair ma410p with two fans. now i overclocked that processor from 3.3ghz to 4.3 ghz at 1.38v. i cannot make it lower then that because the cpu become stable.. now i was stress testing my processor with aida 64 before where my cpu didn't throttles.. but now i tried to stress test it with prime 95 and my processor starts to throttle after 30 seconds or so.. now my question is that should i drop some overclocking or i should believe on the results of aida64? which test is more closer to gaming.. because my main purpose is gaming..

Use OCCT, its not as heavy as p95 but is near the same in finding errors whereas Aida doesn't really find much.

As far as i am aware, depending on the games there are those that would be more taxing in different ways on the CPU because of the different types of instructions. From my experience a game, even if it's old, like BF3 was overheating my PSU. Now i can't exactly speak for every game or can think of which games did what. It all boils down to optimization and what you are planning to play. The difference in tests that you have experience is because of the difference in instructions, if games are all you care about, just test with them how hot you CPU gets. For example, i am running an FX-8300 OC'd to 4Ghz, while i can go over that, my overall system stability would go a bit poof and i would rather play all my games decently, then some better and others crashier. For me, i play old games like Skyrim, L4D2, Payday 2, but i also play newer games like Control, DMC 5 and Metro Exodus, these games can take more use out of my wiggly 8 cores.

So all in all, it depends on what you want to play. If you want to play simpler games that don't require that much out of your CPU, then go ahead and keep the 4.3Ghz OC, but if you want to use newer ones that fully utilize your CPU to the max, tone it down to 4.2 to 4Ghz. Either way, just use monitoring programs like MSi Afterburner for your temps, just to be sure.

Aida64 for thermal testing, Prime95 for stability testing

with aida 64 my temps are in high 80s but it is not throttling .. with prime95 my pc isn't turned off but it was throttling.

Then a better cooler is a good idea

i haven't used prime small fft lately.  

 

R20 repeated runs is good for real world workload temp check and aida/occt for stability.

Test with as many things as possible. If you're doing this for gaming, I'd also test by playing some games, too. Those stress tests can be very useful, but they aren't going to guarantee a stable OC for every single use case.

 

I had a 6700K that could hit 4.5 GHz on a 212 EVO with only 1.3 V, successfully doing AIDA64 and even Prime95 for hours and hours without crashing, but then I'd instantly get crashes and/or BSoDs when running ffmpeg or Handbrake.
