What does "all-complex" mean here?
Does it affect FFT cutoff?
Seems that throughput becomes higher with all-complex FFTs.

Default Trying to tame this monstrosity (i7-12700K)

MB: ASUS Prime Z690-A
CPU: i7-12700K (8 P-cores + 4 E-cores)
RAM: 32GB Corsair DDR5-5600 C36
PSU: Corsair RM750X (80+ Gold)
OS: Win 10 Pro 21H2


This motherboard has a bit of a weird understanding of 'auto', which I thought would be 'stock' Intel specs.
Instead the mobo automatically tries to overclock and override the normal turbo modes. So I quickly disabled that function. In ' auto' mode the mobo also overwrites the Short and Long term Turbo Power mode with 241W .

I might have gotten a bit too optimistic with buying memory DDR5-5600 C36. Runs OK for Cinebench and Prime95 benchmarks, but for any production (LL DC test) it starts producing errors within 1 hour. Loosening the timings to C46-46-46 only delays the production of errors. So I've backed off to DDR5-4800 C46 (JEDEC spec) for now.

Here some test in the Frankenstein mode
With my pretty decent air cooler the hottest cores hit 90C when running Cinebench or Torture test on all cores....

The value for 1-core benchmark may be incorrect.
V30.7 has a bug. Use V30.8 for benchmarking.
