Solved Unstable new i9 13900K PC multiple BSODs

It is most likely a ram issue. This has been confirmed by testing using MemTest86.

To clarify re the ram. I have two sets of the Corsair Vengeance 36-36-36-70 5600MT/s 16GB x 2 DDR5.

I must add I don't intend to have 4 sticks of ram in motherboard at once.

Ram Kit One

Inserting both sticks into A2 and B2 slots boots the PC but system is extremely unstable (the crash dumps are posted above).
One of these sticks runs the pc fine if installed into slot A2. Currently testing this one in Memtest86 and no errors so far.
I also tested both sticks together in Memtest and one stick generated a number of errors.

Ram Kit Two

Inserting both sticks into A2 and B2 slots, the PC will not post.
One of the sticks on its own in A2 boots fine and runs stable in Windows 11. With the other stick in A2 the PC will not post.
The stick that works fine in Windows 11 has been fully tested in Memtest and passed.


It looks like I've been unlucky to have two sets of the Corsair ram, both with one good stick and one faulty stick.

The ram is going to be RMA'ed to the retailer (who have their own technician's and are one of the leading sellers of computer parts in New Zealand). They have promised me that they will get the testing of the ram completed quickly and will replace any faulty ram.

It is most likely a faulty ram issue. If on top of that there is something else wrong like a bad motherboard I think i might

@Marcus Vinicus, I may be confused, but if you have 2 sets of RAM, and you have 1 faulty stick in each set, couldn't you just use the 2 good sticks together and see that it works fine?

I'm gonna try that. I've been doing a lot of testing in Memtest of individual sticks of ram so the PC has been tied up for hours.

I've put the two good sticks of ram in the PC and it has booted and is currently running fine without any BSODs/crashes/error messages in Event Viewer. I'll let it run for a couple of hours before I'll have to RMA the ram to get it replaced.

So if the PC runs stable with these two ram sticks that means the motherboard, CPU etc. are ok. I didn't think that either was the issue at any stage.

I am confident that this is now resolved with two good sticks of ram now installed. I'll give it another couple of days before marking this solved.

Thanks to everyone for your comments and suggestions. There are some really good and knowledgeable people here.

Also thanks to the technicians at Computer Lounge in Auckland New Zealand where I purchased the ram. These guys were really helpful and gave great advice and service.

The BSOD issue seems to be resolved with the replacement of the faulty ram with 2 sticks that passed testing in Memtest86.

Now marked as solved.

whatever you do -- don't mess around with the CPU -- if that is damaged at all then two things would normally happen -- the Machine wouldn't even power on (some might but some won't if there's no interaction with the CPU) and the fact that you can even start windows is an indication that the CPU is OK.

There's probably some settings / overclocking or whatever on the mobo that aren't correct.

Just try and boot ANY Live Linux distro and see if the system is stable. If it is then it's Windows / board settings.

I'm sure if you check the Mobo software and settings there's something awry. Go for the lowest possible level of performance and then gradually alter at will --but ONE thing at a time or you won't know what caused the defect.

OK I see you've fixed it now !!! - surprised faulty RAM -- I've built loads of machines over the years --can't say I've ever had a case of faulty RAM though -- just bad luck !!! but glad you fixed it.

Let me add my two cents after struggling with same issue for over 6 months. The problem is NOT faulty ram (although in some cases it might be possible). The problem is in the BIOS settings. Remove overlooking if you have this available. Also do not use the ecores. Once I did these things my system is finally stable. It was a hard lesson learned for a guy who has over 30 years experience with computer hardware. Yes, I have an Intel I9-13900k processor sitting on a MSI - MAG Z790 TOMAHAWK WIFI DDR4 Socket 1700 USB 3.2 Intel Motherboard with 64gb of ram. Running Windows 11 Pro.
