I have been tweaking and testing my OC on my new 9900KS this past week. Intel Burn Test, Prime95, and Aida64 AVX testing has been pretty easy with a -2 offset on 5.1 and 5.2Ghz. The hardest test to get stable for me has been OCCT small data batch nonAVX. That crashes me most of the time. Here is where I am so far.

MB: Asus ROG Hero XI Wifi
AIO: Corsair H150i
CPU: 9900KS
RAMN: 3600 Corsair Vengeance Pro
All numbers are manual voltage all core, with turbo on, c state, speed step and speed shift off, and all current limits maxed. This is also with multithread enhancements off. Pumps and fans are max.

5.0Ghz is cake and I have not tested this much. I would expect stable at 1.26 or maybe lower
5.1Ghz, 1.300v, 4.6cache, -2AVX offset, LLC6 I will post temps when I get home, but they are very much in the safe range on both AVX and nonAVX.
5.2Ghz, 1.385v, 4.7cache, -2AVX offset, LLC6 (LLC7 is unstable), temps in the high 80s on NonAVX testOCCT Small data
I have not tried to push the cache clock past -5 from core clock.

I have run many many 1-2 hour Prime 95, Aida64, and OCCT tests. If the config will pass 1 hour of small data OCCT NonAVX test, it will be stable on all the others. This test is also pretty harsh on temps.

I see a a tremendous voltage difference between what is configured in BIOS and what CPU-Z and HWInfo report. On the 1.385v load, 1.365 shows up at idle and drops to 1.2s under load, Again, I will post actuals tonight.

Cinebench varies 60-70 points, but high score so far is around 5050.

Intelburntest is an obsolete joke. It was made for Core 2/Conroe processors and uses ancient Linpack binaries that do not support AVX. I have absolutely no idea why people even bother with it now. On 9900k's, it uses less current/watts than small FFT 29.8 build 6 prime95 with AVX2/AVX disabled! That's how awful it is.

If you think OCCT is hard to pass, you haven't tried LinX 0.9.6 with 35000 sample size. To pass that, ALL residuals in each loop must match (each Norm and each residual must be the same as the one above or below it).
That test puts prime95 to complete shame.

Unfortunately that test is dependent on proper RAM settings since it is uses RAM extensively, unlike small FFT AVX prime95 or FMA3.
Small FFT FMA3 prime95 is the second hardest test to pass (using 29.8 build 6).

Surprised your processor still works after doing this one.

Why you say that? Temps were in check. Average package temp was 89* with max temp on any core being 91*. Average core temp was 80-88* after an hour.

At 5.1 1.300v, NON-AVX was was average package temp of 79* with all cores average being between 73-78*.

OCCT small data Avx on this one ^^^ was pretty toasty at 95* package average and cores averaging between 87-95*. I am sure the 5.2 on AVX would temp throttle.

Prime Smalll Data AVX on this one ^^^ was essentially the same. 96* package average and cores between 87-96* average after an hour.

On Intel Burn Test, what I like about it is it will throw an error and not blue screen. OCCT will flat BSOD if the clock gets out of whack. I use IBT to get close and then refine with OCCT and/or Prime95.

At 1.385 Bios voltage for the 5.2, my CPUZ vcore shows 1.359 at idle. Same for HWInfo. When I put it in a load, that shows to go down to 1.279V. I swear my Gene XI did not drop or show that far off, but this Hero XI does. This is with a LLC of 6. Another head scratcher for me is 1.380, 1.385, and 1.390 voltages in BIOS all show 1.359 in CPUZ...

Look at what you wrote in my first quote very carefully please.

The XI Gene and XI Hero have a different VRM so I’m not surprised.

Have you tried actually measuring voltages with a multimeter? My guess is a high quality multimeter will show a different story.

Lol. Yep typo. 1.850 would be a melt down. Haha. I’ll fix post to 1.385...

Yeah sorry if I was nagging. You know with the Asus boards setting CPU PLL OC Voltage to 2.6v and VCCST (standby) to 1.6v at x52 multiplier....

I have not tweaked CPU PLL OC Or VCCST yet. Please tell me more.

x52 or higher multiplier sets CPU PLL OC (Pll bandwidth??) to 2.6v (No, this is NOT a typo) and Standby voltage (VCCST) to 1.6v if they are on auto.
Manual adjusting fixes that.

What do you suggest they be? I may see what the 5.1 levels are when set to auto and just Manually set them to that I guess.
