![]() The idea is to lower the risk so that it is as close as possible to the risk you would encounter at non-overclocked speeds. None of them are the end-all be-all of stability or reliability. These methods are intended only to give you an idea of what problems you might encounter with a specific overclock. You should run whatever overclock you are comfortable with. Stability testing is largely a subjective endeavor. Prime 95 is my last test because it takes the longest. I think blend is folly for CPU stress testing, because it takes stress off the CPU.įor C2D you can use large FFT b/c it still fits in the CPU cache.īefore I do Prime95, I'll usually do 3dMark01, 03, and 05, and the 3 most stressful games I have at the time to test for all-around stability. If you're including RAM you're not getting the full stress on your CPU that you would with CPU-only testing. The idea with these stress programs is to put your CPU through more stress than you would see with normal computing so that you are stable when doing just about anything you could throw at it. If you're too lazy to run MemTest86, then I suppose using Blend is a cheap way to get some minor testing done on your RAM stability. The thing is, if you already used MemTest 86 to test your RAM for stability at this clockspeed, then it's a waste of time to use Blend. Unfortuantely no stress is perfect but I would stress for at least 4-8hrs on large fft.small fft is primarily cpu, large seems to at least stress some ram and cpu I have seen many say there seem is orthos/prime 95 stable and crashes in games or some other app which is odd to me.my opteron large fft pushed max temps? cpu, ram, mobo etc.I have notice blend put alot stress on ram, cpu and chipset.is one stressed more not sure but isolated small fft seems to push a higher cpu temp than blend and early runs of large fft. I just ran a C2D 12hrs blend stable when I stopped. Others recommend 12 -24 hrs of each small, large, blend testing. ![]() Prime95 and all stress testing is a funny thing.I found in the past if I was stable for 12hrs plus on large fft.I would have no issues on my system Run 2 simultaneous instances of all the stressors sequentially one by one, each for 2 minutes and summarise with performance metrics at the end.Funny if you read Prime 95 they say to run at priority of 1.persoanlly if you are doing nothing else when stress testing(which I do.walk and let it run).I see no reason to change the priority. Stress-ng -sequential 2 -timeout 2m -metrics Runs 8 cpu stressors and stops after 800000 bogo operations. Each stressor will use 5% of the available file system space. Runs 2 instances of the mixed I/O stressors using a total of 10% of the available file system space for 10 minutes. Stress-ng -iomix 2 -iomix-bytes 10% -t 10m Runs for 60 seconds with 4 cpu stressors, 2 io stressors and 1 vm stressor using 1GB of virtual memory. stress-ng -cpu 4 -io 2 -vm 1 -vm-bytes 1G -timeout 60s You can easily install and put the required loads on all the above resources Here are the links-īut personally, I am a fan of stress-ng application. If a specific python solution is required, then I would recommend stress and stressypy modules. ![]() That is why the task manager on Windows or Activity Monitor on macOS (or top, free commands on *nix systems). A node has mainly 4 resources that are under constant use.
