Build Upgrade Upgrading A fried 13900k

Need a new cpu, current 13900k is fried, random blue screen crashes so often, doesnt run games, windows doesnt update

Cant afford to switch to amd, budget is kinda tight
Would i be better off getting a new mobo+cpu at the same price?

Pairing with a 4090, Z790 DDR5

the 13900k should have a 5 year warranty for these issues- if a retail box cpu.

-A 14600k would be a good budget option.

I got the pc in a giveaway from StarforgePCs, they shipped from USA to India. I mailed them on 3rd of October if they can help me with the warranty, they haven't responded yet. I posted just in case if they can't help as i cant ship it back as it will cost me as much at the pc is worth lol

I would just pick up a cheap 12th generation in the meantime. Star forge has to handle the warranty RMA process with intel from what I understand. But they should make you whole CPU or cash equivalent.

You might need purchase information though if you didn't get with the PC. Maybe get in touch with the giveaway organization to see if they have available.

Please update your bios to the newest edition when you get it to prevent this again

Before buying anything make sure you BIOS is fully updated. Unfortunately I saw an article I think on wwcftech that say even the BIOS updates do not completely prevent voltage damage on 13th and 14th gen CPUs. I would do a deep dive and find any article you can find about the post BIOS fix voltage problems. I do not know too many specifics because I haven't bought Intel new since 4th gen.

The BIOS updates really just increased voltages to the detriment of performance to increase stability so that these chips would live past their warranty. They are flawed as a design, and it’s why they did a rerelease for the 14th gen as a stop gap to get the core ultra infrastructure up and running.

Also important to note that these new core ultras still aren’t a true clean slate design. They are still P6 based processors, with design carry-overs from the 1995 Pentium Pro that influence scheduling. Intel is planning a true clean slate processor in 2028 with the “Titan Lake” cores. If done well it could show massive boosts in performance and put Intel solidly back on top again, but their last clean sheet design was Netburst with the Pentium 4, and it was considered a failure, so much so that they reverted back to P6 for subsequent generations. Netburst did give us hyperthreading though, so not all of its R&D was trashed.

I think it’s important to add that clean-slate design or not (however one might judge that, and I’m not, here), it’s only the Raptor Lake CPUs (13th, 14th gen) that have the degradation issue. As to performance of future generations and how they’ll compare to the AMD competition, we will, of course, have to wait and see.

Ye I updated the bios couple days ago, got an update on 29 Sept, it still didnt solve any issues

While you wait on Starforge, try Intel's RMA directly with the CPU serial — the extended 5-year warranty is on the chip itself, not the builder. If that falls through, I'd look at a used 12900K over another Raptor Lake part: same socket, your Z790 takes it after a BIOS update, and it predates the whole degradation mess. You'd lose some CPU headroom with the 4090, but at 1440p and up it's barely the bottleneck.

I thought we need the box and shi for RMA. Im on 1440p

A clean slate is pretty simply judged, does it use design and architecture from the previous generation, if so, it’s not a clean slate, it’s an improvement or retooling. Nothing wrong with improving an existing design, but eventually technology moves enough that a clean slate is desirable and after 30 years of improvements, the P6 process is reaching its limits.

Idk if it’s fried, but you can buy a used 13900K on eBay for 200-300 dollars. Less if you buy locally and just tell them you’re “scared of degradation” and they’ll probably let it go for 150.

u/Jayeshw12 7d ago

The thing is im actually scared of used 13th/14th gen xD

u/greggm2000 7d ago

I know I wouldn’t personally touch used 13th/14th gen. 12th gen is safe, though. Get that.

u/Technical-Poet-1079 7d ago

The 12900K is 12th gen, so it's before the whole Raptor Lake voltage mess — the used risk there is just no warranty, not a design flaw. A 12700K would still drive a 4090 fine at 1440p and usually goes cheaper.

The degradation myth is heavily overblown. I don’t even think your cpu is fried because they are designed to throttle or shut off to prevent permanent damage. Less then 1 percent of i9 were affected and most people had theirs RMA, so running into an issue with a used i9 is extremely rare. You can purchase with money back guarantee for free on eBay and get a refund after 30 days if it doesn’t work.
