No over-clocking involved in the instability I was talking about...
It was simply trying to run faster RAM (DDR4/3200) - which is much more of a benefit with AMD's Infinity Fabric architecture than with Intel. The level of flaky behavior was startling (especially upon first release).
Turn off the onboard audio... and SMT (Simultaneous Multi-Threading - Hyperthreading in AMD speak) was gone.
This was across all the top motherboards/brands (not limited to one model).
Gigabyte's AX370-Gaming 5 was the most stable with DDR4/3200.
Even so, after a few days testing, the motherboard would no longer post.
Had to reset the CMOS and lower the RAM speed to achieve 100% stability.
Ironically, you can pop almost any decent DDR4/3200 in almost any Z370/Z390/X299 motherboard... and it'll run rock-solid.
With the following two CPUs being recently released (and affordable), you've got an ideal DAW processor.
- i7-8086k (six cores, 12 processing threads at 5GHz)
- i9-9900k (eight cores, 16 processing threads at 5GHz)
Super high clock-speed and up to 16 processing threads... in a mid-tier CPU
Z370/Z390 Motherboards are rock-solid... and were from first release
No annoying compatibility issues (like the one I mentioned with Boost 11)
For those that don't know...
Not all processes in a DAW can be multi-threaded.
This is why high-clock speed is so important (never want to sacrifice significant clock-speed for more CPU cores).
In an ideal circumstance, you want high clock-speed and more CPU cores.
This is exactly what the 8086k and 9900k deliver... without having to go the expense of socket 2066 (typically considered more of a high-end workstation).
Lack of Thunderbolt-3 is also a factor for many folks.
Even if they don't want/need it now, it's nice knowing it's an option.
I have zero against AMD.
If the balance shifts, I'd be just as happy to use their CPUs.
