That sucks. But I wouldn't give up, I would respectfully lean on that seller a bit harder. Because it's pretty damn hard not to be able to produce a receipt especially if they have an account with the place they purchased it from. Otherwise, they can source their CC.
I requested RMA since I got an early batch January 2023. I had all the limits and undervolting in place and had no issues. I just sent back for oxidation since INTEL did not clarify it. I would buy it again with all the fixes. They way I see is INTEL should have limited BIOS settings right off the start.
I would seriously consider reaching out to Intel and processing the RMA. Especially since you already have a 12700K. I had Intel cut me a check for my 13900K and I bought a 12900K for 250 bucks. You already have the CPU that's like 90+% of the 13700K without the temps and the issues. It's free money for you at this point. Go for it! Bank it and wait for something better or put it toward a 9800X3D.
Bear in mind, I never set it above 1.49v in the bios, and the actual voltage reported in windfows never rose above 1.53v. Bios defaults actually made it go higher than this. It's watercooled with a massive radiator andwater temp never rose above ~30°c
You can do what I did, sidegrade to a 12900K(F) for like 240 bucks and pocket the rest of their cash refund. I suspected that their mitigations were only delaying actions for 13/14th gen. You can't fix broken shit. Even though my 13900K never even hit 6 Ghz, it still degraded. I think they pushed the architecture too hard to try to remain relevant. It's all poo.Well, replacement 14900K has basically died again, or rather seriously degraded in a matter of months!
I'm not sure it was ever stable at 6ghz, but recently I've devised a new test of running prime95 on a single thread and assigning it to each core in turn to determine highest speed for that core. Well, my supposed 6.1ghz all core overclock is utterly shattered, here's how my cores are holding up after only a few months:
Core 0 - 5.6ghz
Core 1 - 5.7ghz
Core 2 - 5.7ghz
Core 3 - 5.7ghz
Core 4 - 6.0ghz
Core 5 - 5.9ghz
Core 6 - 6.0ghz
Core 7 - 5.9ghz
The first few cores have seriously degraded!
These chips are just pure shit. That Arrow lake CPU speeds are so low says to me that pushing beyond 6ghz was just a short term leap to win benchmarks and reviews and these chips just couldn't last for any decent amount of time. I think we're going to see all people's 14900K chips just slowly die over time.
This will be my last Intel chip for a while.
Yeah, that's great... I ended up pickup up a 14700K for 295 bucks and that's a definite upgrade from the 12900K I was running after the 13900K became defective. Been running flawlessly the entire time. I undervolted it and it's stable and +10-11% Single Thread, +20-22% Multithread. No complaints. I will look for the new microcode BIOS update for this as well.
Looks like Dell started releasing it already.
That's awesome!
If you guys have the receipt of purchase Intel will refund your money or give you a new processor. It's worth the effort.
The microcode does not fix an already crashing/damaged CPU. It only prevents a CPU which is still ok, from getting damaged and starting to crash.
I know that. But the customer did not initially want to buy a new CPU or any hardware. The machine was just locking up on occasion. Early days.
That's a great way to lose your investment. When it does, eventually, cook itself... Intel will not honor a replacement or refund. The flaws are there, whether you recognize them or not. It effects damn near every CPU in their 13th/14th gen lineup that's not a essentially still a 12th Gen part rebranded.
If you are on the newest bios, it will probably be fine.
Personally, I wouldn't buy it. Unless he's the kind of friend that will process the RMA for you and still has his original receipt of purchase. Plus, once he discovers that Intel will give him 600+ dollars for the CPU good chance you don't get the system anyway... Just trying to cover all the bases here. If he got it in sketchy fashion and can't RMA it or won't work with you to get it replaced, don't do it.
He'd definitely let me process the RMA with the info, but maybe I shouldn't mention the refund...
You just lost credibility as any kind of friend I would ever want to have. Because a good friend would tell his buddy he could finance his terrible choice of Arrow Lake adoption on the refund value of the 13900KS

Alright, good point, I'll tell him the truth- what I said would be a shitty thing to do
How much tuning have you done exactly? I normally don't mess with more than just the adaptive offset and llc. How much more is there to undervolting that I'm missing out on? Ring bus?Wish I had something more positive to post about the 13/14th Gen processors. This might be somewhat positive. At least I am taking it as such. The latest BIOS microcode update specifically addresses long idle times where the processor sits for days. I think one example was 8 days... Great that they are still working on the processors, but seriously... the issues with the Raptor Lake processors never seems to end. Makes me wonder if after this microcode I am going to have to painstakingly re-input the undervolting parameters that took me forever to get in there when I picked up the 14700K. I just want to set it and forget it. Kinda tempted not to update to this new microcode as I never leave it idle. Worst case, I put it to sleep if I want to keep the system in standby.
Regardless, this indicates that Intel is still struggling with isolating the Raptor Lake issues. Wonder if I will end up RMA'ing this one too!
On my 13900KS with minimal tweaks I like to have it at about 5.4/4.1 and it being in between 1.2v-1.27v on 12 cores no hyper threading. The thing about i9s is if you enable hyper threading and all 16 ecores it just keeps adding voltage and for gaming I don't need 32 threads so I shut off hyper threading and shut off 12 ecores. I wish Intel just made a 12 or 16 Pcore CPU instead of all this ecore nonsense. If you shut off all ecores you can easily get 5.7 all cores full time possibly under 1.4v but I personally like to be under 1.3 at all times. I just don't need to push the CPU voltage because I'm only at 144hz. So I keep the chip as low voltage and cool as possible.
The voltage is the issue causing degredation not the temperature even though it's not good to run at 90c-100c more than often almost always it's the rediculous high over voltage that was frying the CPUs ring bus. That's why running an even lower all core frequency at 5.4 or 5.5 across all cores full time no single core boost is ideal and your chip will last longer than its processing relevancy.
If I'm investing more than a couple hours into this business I usually get fed up these days. Every BIOS is different and every time I go hunting for the undervolt settings (depending upon which manufacturer makes the boards) I end up pulling my hair out trying to dial in the settings. Now, there are two ways you establish a successful undervolt.
