10 core @4400mhz+ with 4000c16/c17 tweaked is pretty good. In BF V it's maybe better than 9900k too, due to higher memorybandwidth and x299 is better for sli

Turns out Ive got bad RAM which might explain the seemingly random lockups and crashes I am experiencing during anything that uses memory. 12 memtest errors over 2 passes.

Have replacement RAM arriving today.

I would love to get this CPU above 4.4Ghz however my H150i even with push/pull high RPM fans cannot keep Prime95AVX under 90c at 4.4 so I am using a -2 offset for AVX.

CPU appears to need about 1.22v for 4.4Ghz normal / 4.2AVX on all cores with HT ON.

Might just have to put a little custom loop in there with an EK Coolstream 360 XE and push pull fans.

Yes, somewhat. My 4.3 GHz 7980XE limits my 1080 Ti SLI in the majority of games at 1440p. With 2080 Ti NVLink, it would be more so.

I am assuming by 1.90V you are referring to the VCCIN or made a typo otherwise it would probably blow up lol. 1.22V does seem a little high. I find that once some cores start getting above 90C the stability drops rapidly and the voltage required increases more on Skylake-X.

How old is your HX1200? Are the 5V and 3.3V voltages where they should be? I had an issue once where increasing CPU voltage actually reduced stability, it was caused by the PSU.

Im now rock solid stable at 4.4Ghz with 1.22v V. VCC IN is 2.1v.

Passes the following, plus hours of gaming:

10 Loops ASUS Realbench BENCHMARK MODE
1hr Prime95 CUSTOM 1344K FFT IN-PLACE
2.5hrs Prime95 SmallFFT AVX/FMA3 Enabled (complete loop of all the smallFFT sizes)
2hrs ASUS Realbench STRESS TEST MODE MAX RAM
1 x Heaven Benchmark run
1 x 3DMark Firestrike run
1 x 3DMark Timespy run
1 x Cinebench CPU + OpenGL run
1 x HWBot x265 4k run
8 Hours AIDA64 Stability Test CPU,FPU,CACHE,MEMORY
Pime95 CUSTOM 8-4096kFFT 5Mins per FFT Size IN-PLACE AVX ENABLED (complete loop of all FFT sizes)

I have some headroom to push it further, so long as I don't use Prime95 SmallFFT's with FMA3. PSU is brand new, and I tried two.

Wow, that is some exhaustive stress testing lol.
