Just curious about the CPU-Z stress test.
Just curious about the CPU-Z stress test.
I achieved a 4.5Gz overclock on the 4690k at 1.280v DDR3 1600. It's stable during 10 Intel Burst tests at full stress (6Gb). I prefer quick results now, so I avoid using Prime95 all day; some say Intel Burst is more accurate and faster at spotting issues, but honestly, when I run the CPU-Z stress test, my computer restarts every 30-35 minutes. Does this behavior from CPU-Z really count as reliable since I don’t use it often? What are your thoughts?
I achieved a 4.5Gz overclock on a 4690k at 1.280v DDR3 1600. It's working well with 10 Intel Burst tests at full stress (6Gb). I prefer quick tests over Prime95 since some say Intel Burst is more accurate and faster at spotting issues. However, when using CPU-Z stress tests, my computer would restart every 1-2 hours during the test—possibly due to a BSOD, though I might have fallen asleep while running it. How reliable are these CPU-Z stress tests? My experience hasn’t been very positive; I usually rely on other programs for thorough CPU testing. CPU-Z is better for quick checks but doesn’t push my CPU hard enough to cause real strain.
I get that it doesn’t produce as much heat as other programs do, but I can understand that because real-world applications usually generate less heat and their stress tests might differ from others. I know passing Prime95 all day doesn’t ensure my PC will handle games well. What I’m confused about is how to tell when the CPU-Z stress test has finished. My PC experienced a crash after 30-35 minutes of running the test, but once stable, I can stop it. Then I ran another test with 4.5gz 1.3v for over an hour without any crashes, and my screen stayed black except for the cursor and blinking light, which felt like it was still processing. I’ll consider that a sign of stability since CPU-Z uses all my system resources. Any other advice?
What cooler are you using? Your voltage looks a bit too high for 4.5ghz on a 4690k. It's not extremely dangerous, since 1.3v seems to be the threshold before damage, but overall it's on the higher side.
CPU-Z and LogicalProcessing suggest it doesn't put enough stress on the CPU. For a 4690k, try running prime95 version 26.6 (don’t go higher) and perform 10-minute FFT tests. A CPU test on Aida64 should take about half an hour to an hour. You can also run an FPU test for 15-25 minutes, but be aware it will generate a lot of heat—so if you already have a stock cooler, it might not be worth it.
For comprehensive stability, perform a full test in Aida64 lasting around 45 minutes to an hour. If everything checks out, you can continue with your activities and games while keeping an eye on the situation. Remember, quick results don’t guarantee long-term success when overclocking—patience pays off.
Take your time investing in your overclock, verify its stability, and it will reward you well.
Good luck!
I'm using noctua nh-u14s, 4.5gz can run smoothly only at 1.3v if I set it that way. I've used prime95 and aida for 24 hours but found it still unstable for gaming, so I increased the voltage to 1.275. With 1.3v and 4.5gz I don't want to risk using prime95 because the temperature difference was extreme at that limit. I'm just curious about clocking at 4.5gz and stress testing with CPU-Z cos I haven't tried before.
