Did I Run Prime95 Right?


It also runs hotter because when one thread is waiting for the RAM to respond, the other thread wakes up and continues to do calculations within the CPU. When you run two or more instances of Prime95 on a multi-CPU machine, each instance doesn't really settle down and run only on one CPU. This is a very useful characteristic if your computer is flakey and you're not sure which component is causing the problem. Open the pod bay doors, Cortana.

I just hope I don't ever get any data or torrents that have been on your system.

It reached 18 hours before it crashed. The solution is to find the right settings for IntelBurnTest that will result in stressing the CPU while leaving just enough free CPU cycles to allow FurMark to get GPU load Another piece of advice is to stick to “offset mode”, i.e. How To Read Prime95 Results Reboot and run Prime95 Torture Test for 5 to 30 minutes and repeat this until the Program displays errors.

When Prime95 fails in any way, the very first thing you should do is run a memory test to rule that possibility out. How To Use Prime95 To Stress Test Cpu The "Min FFT size (in K)" and "Max FFT size (in K)" allow you to pick the minimum and maximum size of the FFTs done in the test. But if you've been overclocking, you know what to do. That doesn't seem right.

As such, Blend and Large FFT's both have cyclic workloads which are unsuitable for CPU thermal testing.Other stability tests such as Linpack and Intel Burn Test have cycles that load all How To Stop Prime95 Test Not all psu's are made equal and some allow for voltage drop and noise on the rails which will certainly cause the effect you are experiencing, sometimes only a little can If you're still using the stock cooler, you should pick up an aftermarket cooler if you plan on overclocking.Actually, if you are using an aftermarket cooler, what kind of voltages are Reply to CompuTronix Related Resources Prime95 test question Prime95 Test question & some others ( noob ) solved prime95 questions about the test Stock prime95 test questions Prime95 torture test questions

Straight Power E9 580 W (564 W on the 12 V line), the symptoms were exactly the same. Also note that MemTest86 is not as good a test of your CPU/RAM interface as Prime95 because it doesn't heat the CPU as much.

Though very useful, its not sufficient to be blindly accepted as fact. Prime95 Blend Or Small Ffts This picks out slight miscalculations which will screw up a few bits and bytes hither and thither, but may not crash your computer.

Repeated that evening. H100 Corsair for cooling. Waiting to install the second version until the first completes its one hour test to make sure the code is working on my laptop. Prime95 Not Using 100 Cpu The RAM data is passed in both directions between the CPU and northbridge and if the northbridge is a little weak, it may have problems communicating with a hot CPU.

If you run Prime95 and then try to start another copy of Prime95, you only end up with one instance of the program running. But after all it's your computer. If you get errors only after several hours, this is a result of slight instability because the system is running with little or no margin. There is a point that is rarely pointed out on any forum threads related to stress testing with Prime95 to verify stability of overclocks.

It's then time to back down and repeat the Torture Test until there are no errors for at least 12 hours.

Reply to Mysticking32 SR-71 BlackbirdMar 2, 2015, 12:12 AM I use Aida 64 also. Does it mean that it's stable?

Each instance will not contact the server and retrieve a second exponent- from now on each instance will want to do separate exponents and you will not have to worry about If you're running out of ideas then give it a try. jjd99dApr 20, 2010, 2:44 PM Prime95 24 hours is accepted as stable with the O.C. It's averaging around 5C lower than before, which I read would happen (due to the thermal paste needing to get warm so it can spread out better).

foolycoolyApr 28, 2009, 3:41 AM Interesting note for the 'extremists.' I ran prime95 blend for 13+ hours overnight w/o a hitch at my current settings.

A friend of mine was running a prime unstable pc for 5 months with no single problem while playing games etc. Permalink Radox-0 2 Builds 1 point 11 months ago Usually a bios update will not affect overclocking performance or at least negatively.

They usually run it 12-24 hours... I'm kinda trying to figure out if my ~75C results were due to me having a smaller aircooler, me incorrectly installing the CPU cooler, or a combination of both. Is that still an issue? So the IBT and Prime95 tests alone does not mean jack.

If the cores share one memory controller then you'll probably get maximum stress by running the blend test on one CPU and running a small FFTs test on each of the Meanwhile my prime95 was failing with Blend test until I got to 1.35 volts (which is what is set automatically for 4.6GHZ in the BIOS. your pc is probably shutting down to protect the cpu.
