<p>Thanks for reaching out to us about this. Could you let me know what version of Geekbench 4 you're using and what you mean by "blackout"?</p>

restart before completing the whole test. It was Geekbench 4.1.4. And now<br>
it seems is OK with Geekbench 4.2.0. But there is another problem. It seems<br>
unable to get the correct memory bandwidth with a quad-channel CPU. I<br>
checked some samples like 7900X, 6950X, and my own 7820X.<br>
the memory copy/bandwidth marks are far too low, approximately a<br>
dual-channel value. Here is one of my own score:</p>

<p>I see, thanks for clarifying. I will look into the 7820X score and let you know as soon as I can if I'm able to provide some more insight into the issue.</p>
