Hi, some help from an expert please!
I'm an X470-I owner and I've been trying for nearly a week now to get my 32 GB of ram at the rated CL to not give errors in memtestx86.
My RAM is F4-3200C14D-32GTZ. It's not QVL but it's "high quality" Samsung B-die rated at 14-14-14-14-34 (1.35 V).
Here is the problem: The RAM is very close to stable, just barely not and I can't get it to fully complete memtestx86 without errors.
It's always a few errors, test 7 and 9 fail, but only on repeated passes, it can also just plain pass the test quite regularly.
The system is so close to stable it will pass realbench, aida64 for hours, and stresssaptest likewise.
But the system is NOT stable, it will crash, on the timescale of a day. So I trust only memtest86.
RAM works flawlessly with 16-16-16-40 and passes all memtest 86 no errors, 3200 MHz and base frequency. So it's not bad RAM.
In fact the problem is that there's no way to find any sort of sweetspot for anything. It'll post and boot and run 3200 MHz CL 14 at low voltages, like 1.29 V and high voltages likewise.
It always small, single digits number of errors in memtest.
I've tried many, many things now and I just can't get it to run CL-14 3200.
What I've tried:
1-D.O.C.P and adjusting up and down the soc and ram voltages
2-Ryzen DRAM Calculator safe, fast and extreme presets
3-Vipeax's settings from

https://rog.asus.com/forum/showthread.php?101707-16GB-RAM-modules-for-Crosshair-VII-2700X/page2#post...And I've likewise tweeked voltages and sub-timing settings in all the above. I set the timings loose or tight, I adjust sub-timings,
it's always the same result, a close-to-stable but still errors . It's very frustrating, crazy frustrating.
Is it time to give up? There's something just odd, because it's so close to stable over such a wide range, I can't pin anything down.
Any help much obliged,
