AsRock Freeze issue: FM2A88X Extreme4+

Since I detected some access from countries other than Japan, I translated assuming they might be after this issue.
After the little explanation for Japanese users, I would introduce the issue I faced and resolved.

This is an issue I resolved recently.

<Issue>
Sudden PC freeze
* If the issue happens while the PC is making sounds, noise like "vvvvvvv..." keeps coming out.
* The PC does not respond to any input from its mouse or keyboard.
* After force-shutdown, Kernel power 41 error would be shown on Event viewer.

I would omit what I did for resolving the issue other than this blog suggests, since there are so many PC freeze issues and solutions.

<Result>
I found the configurations below, and after I changed them to "Manual", I haven't detected the same issue.
* CPU Overclock mode
* DRAM frequency (I matched this to the memory specification: if your memory's spec would be "DDR-3 1600MHz, then DDR3-1600)

<My journal follows>
My mom's PC is the one I manufactured. The specifications are the following:
*******************************
CPU (AMD A8-7600 BOX)
ASRock FM2A88X Etreme4+
CFD W3U1600HQ-4G (4G×2)
Intel 530 Series SSDMCEAW120A401
KRPW-L5-600W/80+
Toshiba MD03ACA200
Windows 8.1 Pro DSP 64bit

After my father passed away the last spring, my mom and I decided to upload "how to cook" videos to keep in touch, and this is mainly why I manufactured her PC. After a while since she started to use the PC, we faced the problem I described in <Issue>. (The recent video we made is: https://www.youtube.com/watch?v=p3R5QeKIQcs this video has English CC.)

My PC uses the same mother board although the CPU is different, and I detected the same issue. I also knew CPU overclock mode somehow relates to this issue and stopped it long before, but the same issue started happening frequently these days. And, I knew there was a high possibility that UEFI (BIOS) update would fix the problem.

However, my mom lives in an island and uses Tethering with her mobile phone, so I decided not to deploy the update because it would be such a mess once other incidents happened related to the update until I actually went back home.

So, I finally made getting back home and found that this mother board had an option to overclock the memory frequencies in addition to CPU overclock.

So here we go. The UEFI configurations are as follows.

<UEFI configurations>
* Open "Overclock mode" under "OC Tweaker" (This configuration is for automatically overclocking your CPU.)
* Change it to "Manual".

*Open "DRAM frequency under the same menu (This configuration is for automatically overclocking your memory access frequencies).

* Change it to whatever your memory frequency is.

I think I could actually overclock some without any issue. I thought the issue happened when the memory access suddenly increased like changing time frame suddenly when you are editing and playing at the same time, so I assumed making the access rate static would fix the problem.

I personally think I can't detect physical differences even if I overclock in the moderate range.

So, if you are using the same mother board or similar ones by the same vendor, I would suppose UEFI (BIOS) update fix the problem. I set the same configurations in "Auto" in my own PC but never face the same issue.

Anyways, if you are about to either change the configurations above or update your UEFI, please do it at your own risk.

In the end, if you are interested in other blogs in my page, please do not hesitate on asking me to translate.

I hope this might be of any help for someone.
Thanks :)
