Hey all

I've had my PC for a little over two years, and have been plagued by the instability issues of these chips.
After Intel admitted the fault, I flashed my BIOS to apply the microcode fix, but the issue remained.
So last week I RMA'd my CPU and received a fresh brand new one as a replacement.

Well, the random restarts are still occurring. Does anybody have any idea what might be causing this or how to fix it?

I have confirmed I am on the correct bios and microcode

CPU: i7-14700KF
Motherboard: MSI PRO Z790-P WIFI
PSU: Corsair RM1000e 1000W 80+
GPU: GeForce RTX 3080 MSI SUPRIM X
AIO cooled

90% of the time the restarts happen when gaming but occasionally when just idling.

Before Intel admitted the instability issues I had actually sent the system back to Cyberpower who just did a fresh windows install and claimed it was "fixed" but the issues began happening again within the first week.
 
If the core speed and multiplier always stay at 55-56 then you are on a decently heavy all core overclock, and running some stuff on an overclock will cause crashes.
You are only supposed to get two cores at 5.6 and all the others go up to a lower max clock up to wherever the software and the other limits allow them to.

Run hwinfo to see individual core clocks.

As far as I can see there is no OC applied. It's a new CPU with a fresh BIOS. All BIOS settings are default besides XMP and Resizable BAR enabled.

MSI calls it enhanced turbo, the equivalent of MCE (multi core enhancement)
At first boot up it should have asked you what kind of cooler you have and the bigger cooler options apply these enhancements.

If the bios at any point has anything about 'intel defaults' then activate that and see if that is more stable.

I did as you said and have been stress testing and gaming all night with no instability noticed thus far.
I will update either in a week or if another restart happens, whichever is sooner. Thanks for the help!
 
Unfortunately I encountered another restart this morning after an hour of City Skylines 2. Honestly this is the most frustrating thing. I have this box in my living room worth thousands of £ which I can't use at all really.
 
What are your temps while running the game? It's the temps and the voltages that seem to be the main culprit. I don't know this to be fact, but I think constant, high temp shut downs damage the chip a little each time it happens. Something like a breaker constantly tripping from too much current draw. That might not be the best analogy, but... That's not to say yours is damaged or has been damaged.

I have the 14600K and learned to undervolt it from the start. I got it at the time all of the overvolting was going on with MOBO manufacturers; about a year and a half ago. I have an MSI Pro 790A-Wifi MOBO.

Intel has admitted that these chips can have flaws and that temps can accentuate and accelerate their deterioration. But trying to undervolt it might be an experiment worth trying.

Yes that's what I've understood thus far as well. I suspect my issue is voltage rather than temps, as I'm usually around 75-80 degrees max whilst playing games.
I don't suppose you know of any decent resources that you could point me towards for undervolting?
 
Sorry, I was away from the desk awhile...

Take a look at this. Post #50. I put all of the links up that I used. I just ran some diagnostics on the PC mentioned where I did these changes today. Temps are still low and I used CPU Lite so that controls voltage there without having to go in and do it "manually."

All the info is there. Watch the videos, especially where the British guy shows how to undervolt on 3 different MOBO manufacturers. Pay close attention to the MSI posrtions - you can skip to just those, really. Pay attention to the guy playing with the different CPU Lite settings - two videos of that, iirc. But before you begin, go into your Bios and exit and save to default settings. I think you said earlier that you have the most recent Bios. If you don't, actually, do that first, then the save to defaults.

From watching the videos you should be able to find the settings, but start with the CPU Lite stuff. It's only one or two settings in Bios. Save changes. Run Cienbench R23 with Hardware Monitor going so you can see temps and voltages of the CPU. Changing the CPU Lite settings from where ever they are down to 11 or 9 or somewhere around there should do the trick.

I hope this helps you. I hope it's not the chip. And, it could be something completely different than we're considering right now too, but this is a good start to check things out. The Reddit link is excellent, but only do that once it's stable with the slightly easier stuff first.

Good Luck!

Thanks a lot man.
Yeah I've been considering the idea that it might be PSU, given that a brand new chip started restarting on me within 2 days.
I'll try all this tomorrow and report back. Thanks again
