Inconsistent POST/Boot issues

[cybing]

Description of Problem: I've recently had some issues with my new PC build (about 3 months old) where it has been recently been real inconsistent with POST/BOOT to windows (sometimes it'll take like 10 retries to get it to POST). After reading loads of forums etc. I'm basically thinking that it's due to unstable RAM. I noticed in event viewer that I've been having Kernel Power 41 Critical Errors since the day I built the PC.

Troubleshooting: One thing I've done already is turned off the DOCP/XMP profile in BIOS so that the RAM is running at the default speed before profiles are applied (from 3600MHZ on DOCP to 2666mhz without profiles). I suspected that my MOBO was not liking the RAM running at that speed (I had timings and voltages on auto too). Will running the RAM at this base value help increase stability? I'm hoping that I might be able to go a few days without the issues returning, if so, this tells me it was a RAM issue. I can always have a play around with timings later on if this fixes my issues. I really need this PC for work so any ideas will be appreciated.

There's like no way a 5900X on a Crosshair Hero can't run 3600MHz RAM. Something is broken and needs to be RMAed.

 

Ensure you have the RAM in the right slots (usually 2 and 4, but consult the mobo manual). If it is, then try a different kit (within return window) and/or RMA your existing kit.

Checked my mobo manual and they're definitely in the right slots (2 and 4). Do you not think it could be an issue with the voltages being out of whack? I ran a Windows Memory Diagnostic and it came up with no issues on the memory. I could try buying another RAM kit and seeing if this fixes the issue if the POST issue returns, so far today (I turned off DOCP yesterday) it's been booting fine.

 

Really appreciate your reply.

You can try making sure you have the latest BIOS revision, and then doing a factory reset on the board, just in case you accidentally fat fingered something in the BIOS, but that board especially is going to come out of the box ready for pretty much anything.

I'm currently on BIOS 2311 which was I think one of the early BIOS for zen 3 on the x570 boards. There have been 7 new BIOS updates since the one I'm currently on. What would a factory reset entail?

Just gonna bump this thread quickly and say that I replaced my 7 year old GPU after getting Q-Code errors that were supposedly related to GPU and it booted first time. Hopefully this has solved my issue now.
