So my best laid plans wrt upgrading my system from an i9-12900KS to an i9-14900KS went awry. Even though I waited patiently for Intel to claim they had solved the 14th gen CPU self-destruction issues this fall via microcode, and gave it another three months just to see what the consensus opinion on the "fix" might be, the i9-14900KS I bought locally and installed on February 15th only took a bit over 2 weeks before it yakked up its first bluescreen bug check.
From there I started noticing applications abending, drivers borking, and BSODs roughly 3 days apart in the beginning, then increasing in frequency until three weeks ago it was bug checking when restarting from bug checks. No bueno! Went through the usual debugging protocol checking memory and drivers and even doing an OS roll-back, but in the end it was clear, that processor was heading towards the light.
I had already moved my old i9-12900KS into a brand new build for my wife so that wasn't available, so I bought another one locally (so thankful for Microcenter Cambridge!), plugged that in, and all of the crapola immediately went away. Let that chip run for the last two and half weeks with literally zero issues, then started the RMA process with Intel to get a replacement 14th gen CPU.
Intel just tonight concurred from all the log files I sent that the processor was defective and they have initiated the replacement process, even sending a pre-paid mailer to return the chip. The rep I'm dealing with when asked claimed that the replacement chips are going through an extra level of qualification testing, so hopefully the i9-14900KS - which as the nee-plus-ultra flagship 14th gen CPU is also the most prone to the failure mechanism that plagued the 13th and 14th gen Core processors - will work for long enough to be worth the effort (and $$)...
Cheers! (fingers crossed
