    Posted: 25 Oct 2017 at 10:18pm
Overall my system is working fine, but there is one very random issue that is happening that I can't figure out the cause and it usually happens after a reboot with Windows 10 where it locks up the system when trying to load windows 10. Problem is it doesn't happen all the time ( I have rebooted win 10 like 10 times in a row previously and it didn't happen once ) and till today it has never happened during a cold boot. Since before today it never happened during a cold boot I wasn't too concerned about it because I don't reboot too often once I start up windows, but today it took 3 resets from a cold boot to get into windows so I am now wanting to get this resolved. So any suggestions are welcome.

The biggest annoyance with this is because I press the reset button (and I don't know why this is the case) during the windows boot up sequence the whole system resets then powers down. It's as if it thinks the overclock has failed. Often times it resets all the OCing settings to default. I don't quite understand why the reset button does this and IMHO it's definitely doing damage to the attached HDDs by doing this quick power down then up sequence. Is there a way to disable this "feature"?

LukerLito, I suspect your memory.  I have a similar system as you and no such problems.  I am running borrowed memory to stick with AMD (FlareX) till the BIOS/AGESA gets fixed.  As a test I would suggest you allow the memory run at SPD specifications ( I suspect it may be 2400 MHz) and see if the problem is gone.  If you look at the memory timings when running W10, is it what you expect or has Boot Training changed them?  I know of no setting to change Reset and suggest you ask ASRock. 
There is a hint that the BIOS/AGESA may have an update, see here: https://community.amd.com/thread/220821
Please include your BIOS and W10 versions in your specifications as well as your power supply.  Enjoy, John.

EDIT: WOW!
Quote WOW, Benja just sent me the new BIOS v1.71 and it works PERFECTLY with my 128gb of ram. Windows is also showing 128gb useable as well. Thank you so much Benja, it is working absolutely perfectly. I am so happy right now. Thank you AS ROCK and AMD! 128gb is so awesome!

Thanks for the suggestion, I totally forgot to check the RAM settings because I set it to 3066 and never changed it again after I found it had some issues at full 3200 speed. It is 3200 ram and now set to 3200 but I didn't change it to that Confused. Next reboot I'll put it back to 3066 and I am sure that will fix it.

Hi. Sorry to ask a similar question in your post. I?™m having the same sort of issue except mines during cold boot. I?™ve gone from 2933mhz to 2133mhz on the memory but i still have to keep turning the pc on and off just to get it to boot eventually.
Thanks for any help.

Lambouk, please go into your BIOS, hit F9 (Load UEFI Defaults), then F10 (Save and Exit) and then use your machine.  If you have further problems, please give us more details of symptoms and what speed you are running your memory.  I suspect you are overclocking your memory and that may be the problem.  Enjoy, John.

Thanks for the help. I was hoping as I spent quite a bit of money on my trident z f4-3200c16d-16gtzb. I?™d get 3200htz or close to it. Do you think I could get 3200 if I upped the voltage.?

Lambouk, I assume you mean X370.  Please post your BIOS version.  If you are running the latest version and do some tuning (voltage, LLC, etc) I would expect you to be able to get close.  Is your memory on the qualified list?  There are several memory experts and I am not one, that can help you.  Enjoy, John.
