Have you set "Overclock Mode" in OC Tweaker to "Manual"? Looking at UEFI 1.31 in one of my tools I see plenty of options that should allow for manual voltage adjustments.]]> Mon, 03 May 2021 21:12:01 +0000 https://forum.asrock.com/forum_posts.asp?TID=18734&PID=86797&title=help-with-undervolt-in-a520mitx-ac#86797 https://forum.asrock.com/forum_posts.asp?TID=18734&PID=86770&title=help-with-undervolt-in-a520mitx-ac#86770 Author: Moncavo

Hello.

I'm using a ITX System, motherboard model A520M-ITX/ac, R5 3600 processor and AXP-90 CPU Cooler, case is NR200.

When I visited his BIOS, I'm fell shocked that has not any way to reduce clock speed, or do undervolt, only overclock.

Is hidden?]]> Sat, 01 May 2021 09:23:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=18734&PID=86770&title=help-with-undervolt-in-a520mitx-ac#86770
