Cinebench Black Screen

[zackdow]

I’m overclocking my i7-7700k and I’ve managed to get pretty good results at 4.7ghz with 1.22v. My temps get up to 75 on the high end with a noctua u12s. When I run cinebench, I’m getting a consistent score of around 900, but sometimes the screen will go black (doesn’t crash, I just can’t see anything on the screen) and then once the benchmark is done it will go back to normal. I’m guessing it’s an issue with stability but the system is fine under stress tests (most I’ve ran is 20min on intel extreme tuning utility). Is this a bug in cinebench or a problem with my overclock?

if GTX 1080 is used as primary display there should be no black out, had that black out on onboard CPU IGP so I figured must be CPU's graphic faulty or inability of system stressing, rather than tortured, you should focus on script optimizing, anyway, why you need high MHz CPU speed for?

Try stress testing with ROG RealBench or OCCT. If it detects errors, up the voltage and disable iGPU from the advanced section of BIOS. Also, 1.22v seems really low for 4.7GHz. Lucky I guess 😉.

Cinebench is better off as benchmarking. Never heard anyone basing stability on passing few rounds of Cinebench.

BTW, do you have LLC enabled?
