Solved Unstable new i9 13900K PC multiple BSODs

Hope this is the right place to post this.

I have built a new system (see specs listed below).
I started the PC for the first time today and it is highly unstable and has different BSODs constantly. It has also been freezing up in the bios.

System
Case: Corsair 5000x
CPU: Intel i9 13900K (PL1 and PL2 @ 253watts)
CPU AIO Cooler: Corsair H150i ELITE CAPELLIX XT Liquid
Motherboard: Asus ProArt Z790 Creator WiFi Bios 0704 updated to 0816
Ram: Corsair Vengeance DDR5 5600 2 x 16GB (failed the Asus Memtest86 from inside bios)
PSU: Corsair Rm1200 Shift
GPU: Sapphire Nitro RX 7900 XTX (this is from my old AMD system and it ran perfectly stable).
Hard drive: Samsung 980 PRO 2TB M2
Operating System: Windows 11 Pro

What I've tried
Installing an identical set of ram to that listed above. System freezes.
I've checked all connections from the PSU.

What I'm going to try next
Remove CPU from MB and inspect pins for damage
Reinstall AIO Cooler with new thermal paste.

I would like to update the bios from the old 0704 to the new one but an not willing to risk it with the system being so unstable.
I am starting to suspect faulty hardware.....

I am a retired IT Manager and have a lot of experience at building my own PC's. I've never struck anything as severe as this before.

Any help appreciated.

Make sure, according to your manual, from left to right, your RAM sticks are in the second and fourth slots.




For the BIOS download it says
PROART Z790-CREATOR WIFI BIOS 0816
Version 0816
11.56 MB
2023/02/24
"-Support high-capacity DDR5 memory kits

“Before BIOS update, please download Intel ME update tool from ASUS support site, and update ME firmware to Version 16.1.25.2020 to ensure optimized system settings.”
Use the BIOS flashback so you don't need to enter BIOS or the OS by using the FlashBack port and button.

Try the memory one stick at a time in slot A2. Are all three PSU cables firmly connected to the motherboard and PSU? What's the CPU idle temperature? My i7-13700K CPU is 32C on a similar Asus board with air cooling. It's unlike the CPU has a problem as you would not be able to enter the BIOS.

He might need to update the BIOS for the RAM, as when it comes to BIOS updates, "stability fixes" generally mean new RAM kits, and fixes to sub-timings.

I've updated the bios to the latest from Asus. This has reduced the CPU temps by 10 degrees Celsius. The PC is still having BSOD's every couple of minutes and is unusable. Also there are flashing pixels (lots of them). I've checked the all power cables including those for the GPU.

I'm not hopeful about this atm and think there is some kind of serious hardware issue going on. All the parts are new except the GPU which is about 3 months old.

I have the log files collected by log-collector. But using the Attach Files says the file is to big

This is most likely your problem.
You might actually want to update your BIOS like someone suggested because it might resolve the issue.

You have to upload the file to any cloud storage and provide a link here in the forum.

Over at the ROG forums it looks like there seems to be a big problem with the 700 series and RAM.
Quite a few threads: Intel 700 & 600 Series

this is the ram on the QVL for that mobo. Are one of these kits your model #?
Also are you running both the 8 pin CPU power and 4 pin cpu power?

Thanks for all the comments and suggestions.

Here are the log files and dumps from log collector

As stated above I've updated the bios to the latest version 0816.

I'm currently running the computer with one stick of the Corsair ram (16GB). The screen corruption has gone (many flashing pixels) using this one stick of ram. This ram is on the QVL but that doesn't mean it will be stable. Note that XMP is disabled and ram is running at 4800MT/s

Yes and Yes. I checked all connections to and from the PSU last night.
In that list my ram is the 1st.

Quick update

I've had the PC running for 2 hours non stop with one stick of ram. No BSODs, no error messages in the event viewer.
Currently running CPU with the multi core enhancements disabled in the bios (i.e. PL1 & PL2 at 253 watts).

In addition to the RAM testing:


1) Please run:

Post a share link into this thread using one drive, drop box, or google drive.


2) Turn off Windows fast startup:

Hi zbook,
Thanks for you advice, I'll get on to it when MemTest86 finishes. Is looking like faulty ram is an issue here.
I've been in touch with the retailer who sold me the ram. And with Asus tech support.

Here's the log file generated by TuneUp.bat

Settings are optimized so that you're unlikely to miss any BSOD as automatically restart was turned off.
If there is a BSOD it should display a message and require a reboot.

Once you've turned off Windows fast startup make a new restore point:

Then continue testing for malfunctioning/ incompatible hardware.

Looks like a bad RAM stick then. You could use the built in W11 memory tester or memtest for more details

Ram: Corsair Vengeance DDR5 5600 2 x 16GB (failed the Asus Memtest86 from inside bios)

It's either bad RAM, or could be a bad board. Try replacing the RAM first. If that doesn't fix it get a different board (suggest not another Asus)

He did already.
