Unable to boot OS after changing Ram speed

[Scroll]

This week I rebuilt my system to with a Ryzen 5600x, on a Strix 570x - f board with Corsair APX 32gb at 3600mhz and a Samsumg 970 nmve m.2 drive as my new boot drive. I've kept my old case and I believe is a pretty decent corsair 750 watt psu and 1080ti gpu. Managed to get all built with ease, installed windows on the new drive and kept a on hdd as it was.

Used all evening and it as just fine. Booted in the morning without issue, then went back to bios to change ram speed but I did not change the profile DOCP instead just changing straight from 2666mhz to 3600mhz. Obviously not a great idea. Posted fine, afterwards black screen and no longer boots windows.

So far I've tried reseting the bios with the reset pin, CMOS, taking the ram out and switching them around and it has not helped. Curiously I plugged in my windows install usb and manually booted to it from bios and managed to reinstall without issue.. Rebooted and it no longer goes past bios.

I'm going to attempt to take the ram out and reset the motherboard after their removed and possibly try with just one stick installed. I find it quite perplexing that i can manage to reinstall windows multiple times but upon reboot I'm stuck.

I believe at this point I'm out of my depth and would appreciate any advice.


Thanks for reading if you got this far.

Taken ram out, reset CMOS pins and battery and tried individual sticks of ram, gets to bios but no boot to windows. I could flash the bios or tear the whole system down and start again. I've checked that connections for the drives and they are visible still on the bios.

This is a really long shot but you could try moving the nvme drive down to the second slot to see if makes any difference?

I can give that a try, I did ponder doing this already but the screws on the shield for the second m.2 drive are ridiculously tight.. And I just managed to get it to boot by plugging the windows usb installer in, going to advanced options and exiting to windows. What kind of diagnotistic can I do at this stage?

Did you increase the voltage of the ram to 1.35v?

I didn't, definitely seems to be where my problem started.

Going to try a few more things tomorrow, after getting windows running via the usb drive updated and restarted and it now seems to be boot to windows realiably. Windows can't see the hdd drive currently so I'll investigate that next and come back to setting the ram up properly. Could I have damaged the motherboard or ram and thats led this odd set of occurances?

So it booted fine this morning and I've continued to update windows fully, and set the docp settings for the Ram which switched the voltage up to 1.35 as suggested earlier. Everything seems to be fine. I can only think that when I did a fresh install of windows I didn't let it fully update and restart when asked.

Thanks for all the suggestions anyway. I never want to touch anything in bios ever again if I can help it.
