12900K / APEX / 2x16gb F5-6000U3636E16GX2-TZ5RS / EKWB Velocity2
Built system and installed 0811. Moved my windows 11 installation directly over from my Z690 Strix D4.
Set XMP1 and 1T. Stable over multiple days/runs of Memtest, Cinebench r23, 3d Mark, Flight Sim 2020, and 4 hours of COD Vanguard.
P-cores "Sync by Core Usage" ranging from all cores @ 50, to 53 single core.
38 Ring bus.
Default E-Cores.
Haven't tried tweaking anything else yet, but I'm very optimistic that I can squeeze a lot more out of the memory and a little more out of the cpu.
The 12900k's SP is 77, but it doesn't seem to mind.
The only annoyance is that Armory Crate has trouble detecting my dram rgb, even with optimized bios defaults. Asus software is SO bad.
When I switched from the z690 Strix D4 to the Apex, I switched from an NZXT Z73 AIO to the EKWB block, D5 Pump, and 360mm PE radiator.
This custom loop destroys the Z73. Temps are around 10c cooler at load, the cpu never even thinks about thermal throttling.
