@looniam That reminds me of when I used Prime95 to stress test my X5690 before I ran it into the ground with 1.5V. It gave me a good excuse to finally upgrade.

Anyways, you should turn off AVX in the latest version of Prime95 using the line you've shown there in the local.txt document. I didn't need to when stress testing my AMD 1800X though.

AMD 1800X w/ Phanteks PH-TC14PE (3850MHz, 100MHz BCLK)
G.SKILL 3200MHz CL16 16GBx2 (3066MHz, 14-14-14-14-28-42-4-6-24-1T)
GIGABYTE GTX 1080 Ti Gaming OC (2038MHz, 5940MHz)
ASUS ROG Crosshair VI Hero (BIOS v6301)

Ya. I am using 360mm aio (one rad).

Honestly I am satisfied getting to 5.1 Ghz super stable, but 5.2 Ghz super stable for 24/7 usage would be nicer though.....

Personally, I think I might have a individual core problem..... Maybe like 6/8 cores are super good , while like 2 of them are bad, that's why I couldn't get 5.2Ghz stable in blender. (It is stable in aida64 though.... that's the weird part)

That makes sense based on the stock specs of the chip. There is a reason the stock boost is tiered by number of cores. Helps them save money on production no doubt.

Is there any statistics over 9900K potential? SL is dead silent ATM, I beleive they keep the statistics up to binned chips launch.

Though, 9900K is already around ~900$ here, in local stores. And thing that makes it more hilarious - that I found my cpu block with wrong jet installed, thus, with right one I get lower temps -> and -surprise- it occured my CPU handles 5 GHz at ~1.32V LLC5, which is fan-f-ing-tastic. And it makes 9900K upgrade even more questionable.

SL is still binning it, so they don't have accurate statistics yet. They will in a few days though. They stated they expect it to be thermally limited though.

Too much money?

i dont believe any of yours "stable" clocks.

or maybe on power throthling aka cpu clocks dropped down on some cores (LinX Gflops show how much GFlops you get=how fast yours cpu/ram truly are).

Give me picture with Prime95 (non-avx) with smallfft preset and 2 hours bench.

And benchmark LinX, at least 1 round calculated and it gives yours GFlops speed.

9900K @5.0Ghz stable with fast rams gives over 520 GFlops...at least here, in Finland. ☺

Seeing as there is no dedicated 9th-gen Intel CPU's thread, thought I'd just post this here and see what other people get.

9700k @ 4.8Ghz ~1.225v
Have tried 4.9Ghz at ~1.285v but haven't done enough testing.
5Ghz would instant-crash at 1.35v so I haven't bothered.
Running -4 on the AVX for stability, not that I use many AVX workloads.

Temperatures are pretty hot with my NH-U14S, granted I live in Australia though and ambient was probably 27C
4.8Ghz with Prime95 (AVX Disabled) FTT ~80-85C. Gaming was ~60-65C
4.9Ghz with Prime95 (AVX Disabled) FTT ~92C. Gaming ~74-80C

So yeah, seems like I lost the silicone lottery here. I'm happy with 4.8Ghz I guess but 5Ghz would've been great.

Those are pretty insane numbers considering non-avx testing... vCore isn't that high aswell.
