Or would it be safe to test further with other programs?
I ask this because I seemingly can only boot into windows about 25% of the time without needing to cut power and try again. Honestly I have had nothing but problems with both my board and this 3900x and at this rate I'm not sure if I could purchase a product from either of these companies ever again.
Yes I am. But I'm also running with fixed 1.23V. Sometimes it boosts to 4525MHz and that's it. When completely stock it used to boost to 4.6GHz here and there, but only 2-3 cores, and even 4.65GHz ONCE. But as I mentioned here before the temps are not great for me when using stock/auto voltage.
Regarding your ram, 6000% is considered stable, at least for me. Try running some games like bf1 bf5, they are good in catching any instability as well. You can always test it further but then you might get into the stable sickness and will basically waste your time instead of enjoying your system. Karhu is also a good test and takes less time than HCI.
This thingy of booting into windows about 25% of the time "sure" is something related to immature bios, ram, and timings all together. Also, as I mentioned here before I was having same trouble with booting up when my timings were too tight, most of the times I was losing all bios config, and once I set 16-16-16-16-58-86, a mix in between dram calc and xmp manual, I was able to solve this boot problem partially, and the write/read/latency is not much different than when I was trying to tight them. Now I can boot no problem 95% of the time, with a "trick" which consists in using the profiles.
1st sets fans to DC
2nd sets cpu vcore, ram voltage, soc and ram speed 3733
3rd sets the four first timings plus tRAS, and tRC
4th sets tRFC
And that's it. I'm running it without any problem, and I came from a 1800X (same rig) with TONS of problems along this two years I had it.
Yes it's a boring workaround, I know, but, as we don't have a polished bios for it, or as the construction of the board regarding ram/cpu does not help (bear what was said in the past about significant changes in ram tracing/routing in the new x570 mobos), that's my way to run the system instead of buying a new x570 mobo. Which is something I don't consider, honestly.
Besides this boot problem here and there, it's running absolutely flawless. Not a single freeze since then.
