System Freeze and Reboot Itself

[3uncubyzt]

So I built a pc on March 7 with specs;

7500F

Asus B650m-k

Galax Rtx 4070 super

Xpg 2x16Gb Lancer Blade 6000mhz

1Tb Kc3000

High power Performance GD 750w Gold

Arctic Freezer Esports Duo Cpu Cooler

The problem is some random times, idle or full-load does not matter, my pc either reboot itself or screen freeze like being taken screenshot. So I've to reboot it eventually. Even though there is no BSOD, I decide to do a memtest86, when EXPO off I didn't get any errors from the RAMs, with EXPO on, the test froze directly and I had to reboot manually. Then, I changed the EXPO profile and it continued without error until the beginning of Pass4, and at the beginning of Pass4, the screen froze again. I had to end the test there. After I checked log file of test which expo is on, there is no single error too. Just freeze and reboot again and again. I think it's about my mobo's expo profile's setting but I need to be sure. Any thoughts? Any advice? Thanks already now.

Note: BIOS and Drivers have been updated.

EDIT: I entered the Expo1 settings manually and tried memtest and it froze again on the first try. I shut down the PC and switched the dual channel ram on the 2 slot motherboard and started the memtest test again without touching the manual settings I made. At the end of 3 hours, the ram passed the test without any error. For now I will observe if the computer will reboot or freeze.

Hello 3uncubyzt,

Regarding overclocking adjustments, unstable parameter settings may indeed lead to system freezes or automatic shutdowns. We recommend referring to the discussion thread Memory Kits - Overclocking and What You May Not Know for additional insights.
Additionally, overclocking stability is influenced by your hardware specifications, system configuration, and related settings. Therefore, gradually fine-tuning the parameters manually to achieve a stable state is generally the best approach.

Thank you.
