discussion 14900k stability

[Solace]

Did anyone have to screw around with voltages to get these things stable? The threads on instability are mainly bios specific issues due to improper configurations and degradation is purely "speculation" I have yet to actually see or experience this since the new bios's enforce proper voltage limits where as older versions apparently were not.

I have experienced some apps crashing on stock settings (generally lower intensity things). I also bumped the IMC to 1.2v for 6000mhz ram when it was at 1.1v before in the rare event it actually is the imc/ram faulting (passed memtest etc...)

The errors are seldom and intermittent. I asked intel to provide a KS edition which is binned better and probably not going to suffer the same issues since I'm 99% certain is simply the configs in place are applying an insufficent voltage curve. I kinda wish there is a benchmark to lock certain frequencies and run through standard tests to see stability.

I wonder if what you are experiencing fits the problem described by Intel in the 0x12F microcode (I posted about that already). But Intel mentioned light loads running for days and not hours.

After Intel patched most of the major voltage-management bugs last September with update 0x12B— which had already bundled fixes from 0x125 (for eTVB-related Vmin shifts) and 0x129 (to curb over-volting at idle)—some systems still saw tiny dips below the minimum safe voltage when they ran light, single-threaded tasks nonstop for days on end. That’s exactly what 0x12F is here to tackle.So what’s in 0x12F? Think of it as a precision tweak to the PCH’s voltage-tracking firmware. When a CPU’s running barely anything, the voltage regulator might get a bit too relaxed, slipping below the floor limit without anyone noticing. The new instructions keep a tighter lock on Vmin, effectively preventing any undershoot.

In practice, most desktop and gaming rigs won’t hit the scenario that 0x12F fixes. But for labs, small servers, or any setup where you leave a CPU idling on light duties for days, this patch could mean smoother sailing. It’s also a reminder that firmware updates aren’t just about new features or overclocking boosts— sometimes they’re critical to keeping your silicon within safe electrical bounds. So do yourself a favor: grab the latest BIOS, flash it, and let 0x12F handle it.

Raptor Lake Instability: Intel Releases Yet Another Firmware Patch (0x12F Microcode)

Suppose you’re a Raptor Lake guru (Raptor Lake is Intel's codename for the 13th as well as 14th generations of Intel Core processors). In that case, you might’ve noticed that Intel just rolled out microcode update 0x12F to stamp out a lingering voltage-drift quirk on their 13th- and 14th-gen chips.

That sounds about right, the most recent crashes were 100% idle. I did have games crashing on the previous chip as well but this one seems a bit better. I'm asking to get a KS chip if I rma it again which hopefully will fly.

Guess I run a .5 offset on the lower freqs to help avoid this from kicking in. Kinda sad how perplexed OCing is these days. 2700k took me 15 minutes to set and use for 5 years in safe ranges with a 10% gain. I simply just want stability and tinkering with voltages gimps performance due to CEP when I thought the LLCs are synced.

Might be boned either way, even at .025 offset increase I still see apps crash when idle. A year since release and still riddled with issues...

Day 1 i delidded liquid Metaled and got the Direct Die fomr TG for my 14900K-KF chips only time iv experienced crashes was due to nvidia gpu drivers.

That was solved not too long ago, I had a bsod from a bad build a while back when remoting to a desktop. Took 3 hours for a softreset to click in from the machine freezing too.

You should check event viewer, it is possible some system services are restarting/crashing under id 1000. Generally when idle, might be mobo specific as some brands have the latest microcode out. Asus does not sadly.

yeah went and checked Dec 2024 last update. ill def take a look as id stated in another post im getting some delayed starups the task bar icons are not starting up nearly like they used to.

id 1000 you say ill take a look at it have not cleared event viewer in awhile so should have a full list if its in there.

I just woke up still waking up so I may even on the right page but if Iam its kind of coincioecently funy becasue I was watchign jaytwocents yesterday and he was trouble shooting someones PC tha thas isues of crashing for noreason ? if I am, wrong just ignore my sleepy head.

he figured out that it was something called intel degradation
again if I am wrong just ignore me lol

This is perfect other then it's Jay2bandwagans. But exactly the issues I tried avoid.
