![]() ![]() XTU will still stress your CPU a lot more than any game. There are very few real work applications that would require your CPU to run at 100% on all cores, for any extended period of time, and there is no game that will do this. I had cases where I could run prime95 for hours but XTU would fail in 5 mins XTU on the other hand checks how stable the CPU is when it’s usage level fluctuates, this is something you will encounter in real world applications, more than anything else a stress test checks for. Prime95 puts your CPU to 100% and checks thermal limits, power delivery and heavy load stability. Ideally, you should always check stability of an OC with different stress test. ![]() And actually it is a far more realistic stress test than a test that put your cpu to 100%. And since CPU is not at 100% all the time, it won’t heat up that much, compared to something like prime95. It is not conservative, it is designed to constantly fluctuate CPU usage. ![]() At any rate, I think any proper stress test should use AVX instructions to some extent to reflect realistic workloads. I have no idea how many games in the future will utilize AVX instructions to how much extent but, if this trend is something irreversible due to easy accessibility of AVX instructions in DX12, I think the stress test in IETU should be considered less realistic and even slightly conservative. Even though these games do not require AVX instruction-enabled CPUs, they indeed use those instructions if they are available. I admit that this example coressponds to one of worst case scenarios because no one plays a game in a way intentionally stressing the CPU. However, I also played Assassin's Creed Origins for about 40 minutes (I let the main character stay put in the most CPU-intensive spot), it easily reached 65C, though it did not exceed this figure. This is because recently many games started to utilize Intel's AVX instructions, which are known for or rather infamous for consuming more power.Īfter running the stress test in IETU for about an hour, the highest VRM temperature was merely 60C. Unlike other overclocking software, it relies on the results of machine-assisted testing rather than pre-characterized data. Enjoy Your Overclock Intel Performance Maximizer helps take the guesswork out of overclocking. One thing I noted during those tests is that the stress test in Intel Extreme Tuning Utility (IETU) is far from anything extreme and actually a little bit conservative. Restart one final time, then run a stress test with the Intel Extreme Tuning Utility (Intel XTU) to ensure stability. As I posted yesterday, I ran a few tests to determine if my H310 motherboard is suitable for running i5-8400. ![]()
