That is better than mostly all 9900k/ks cpus. Most builds need insane cooling for 5GHz AVX loads. So you have diamond CPU's, not gold samples. Prime95 fft 8k AVX must be brutal.a its a 5.1 binned chip, I expect the KS will be as good if not better. @tyler_jrb is the lucky one, his does 5.4
The KF is on a new stepping, the KS is on a new stepping plus voltage bin at 5ghz.
Mine is binned for 5.1 at 1.31v. at 5ghz does 1.2v which is above average but not special.
Best chips do 5.3ghz at 1.32v AVX.
Have posted the radiator spec in other thread.
Thanks for that. Nice chip!

5GHz at 1.2v is not average, that is pure fairytale talk. Stable conditionally, certainly. You can't have both an average and nonaverage CPU lol. If it does 5.1 @ 1.31v then it's a given it'll do 5GHz at a lower voltage.
Average is around 1.3 to 1.38v for 5GHz (AVX).

2 hours of OCCT large with AVX2 and 30 passes of x.264 stress test is my baseline for what I’d consider safe daily stable. This will also pass p95 26.6 small fft.
That would not be a good way to test for stability, for lots of different reasons. It's takes a few days to prove a system stable. Had an overclock pass short tests and crash/reset in games. Overclocking is not a quick process. 3800x RAM tuning was fun. Running memtest86 over and over.

This is for CPU only obviously. That's after spending 6-8 months on the same setup trying all sorts of different stress tests. I'm happy to recommend that to anyone looking for stable CPU and be confident that their daily mainstream systems will be fine for gaming, compiling, rendering and desktop usage.
Other components (ram and GPU) need their own stress tests.
You can do as you please with your setup. Each his own.
for a newer stepping KF? not sure.
My response was partly referring to the post that silicon is always being tweaked behind the scenes via steppings and board firmware
improves.
The reference to ‘average’ is that whilst my KF chip is good at 5Ghz my chip hits a clock wall at 5.3 whereas the best K and KF chips hit 5.3 at 1.35 and can do 5.4 at 1.45.
I don’t have full voltage scaling on my chip to 5.4/5.5 whereas others do, that’s why my chip is not a true golden sample like RSRs and Splaves samples.

What exactly is your definition of "hit?" Realbench? Prime95? Or something weaker like AIDA? Not seen much in the way of consistent results at 5.3. Usually, it's casual gloating and the stability is quite conditional.

Aside from P95 AVX, what would you consider to be quality stability testing?
hit = all the above plus cinebench, memtestx86 and superpi at [email protected].
can’t boot into windows at 5.4 i would expect that even if i could i would need a chiller for cinebench as 22c water temp would not cut it.

For AVX stability I'd consider Realbench at the least. Or multiple instances of the x265 HWBot benchmark.

Well the ones you've mentioned are extremely weak, so maybe that goes someways to explain the conflict of opinion here.

That's fine, here is a realbench 15 minute stress. fans at 200rpm.
Can I you ask you for a favor? Would you mind running OCCT for me? Just hit auto and it should default to Large and AVX2. If you can run that for 30mins and share, it’d really help me compare temps and see what I can gain.
sure what fan rpm profile day-to-day or maxed out ?

Your normal setup. Then I can ref that against my max setup.
I’ll screenshot what it does to my cooling after 2 hours in a bit.
i have never ran OCCT before so didnt screenshot during the test. I did capture HWINFO though.
the test pulls around 50w less than Realbench and hence the temps were far lower - 51C.
my setup is around 500w passive though, with my aquaduct, i cant recommend the MO-RA 420 PRO enough. With a bigger GPU like the 2080ti on the loop i think the fans would spool a bit harder during a full stress test. During gaming it would be fine with the fans on low.

Thank you for testing that! Your cooling is pretty bad ass for sure. It's been a while since I ran real bench but I generally needed a lot lower vcore to pass real bench than i do occt/x.264/x.265. I'll run my daily 5.1 setup tonight and share.
Why is your system agent clock 800mhz? I thought 1000mhz was standard?
This is OCCT after 2 hours. 1.4v bios turbo llc, 52/47x. Alphacool 360LT with Kryo on the IHS. I'd just be happy dropping 10-15c off this honestly.
