Your rams are far better then this LPX kit, also there's a lot of tips in the comments


Anyway, to get always 100 bclk you have to disable spread spectrum, unfortunately is possible only on some x570 board :/
I guess it's on all X boards because I do use that setting and I've seen it on X370 & X570 at work.

There is a large thread on the X370-Pro here. The short of it is that it is difficult to stabilize 3200MT/s with one-dimm-per-channel on it with a Zen1 or Zen+.

Can start with one such blurb about this here.

There is at least one report in there where someone with Zen+ had more frequency with 4x8GB than 2x8GB.

Thanks for this i will take a look. SAdly i still get error with auto timings at 3200 which are over loosen ... so dram calculator timings not stable, and even on auto with TRFC 560 ...
this mobo is a nightmare for RAM ... look those timings, how it cant be stable ?? ...

The timings are unlikely the problem (although too tight secondaries could be late / intermittent). It is very likely the signaling, with some influence from SOC voltage settings and core overclock.

It may be worth reverting the core settings to find the true ram ceiling.

Other than that, the first things I might mention would be similar to what Veii already said. The "normal" RTT for single rank, Samsung B-die would be 7-off-5 (34-off-48 in ohms), although Asus likes to default to off-off-5. CAD drive strength settings to 24-24-24-24 to start.

Besides turning down SOC voltage a little, I would roll back most, or all of the LLC. Too much voltage can increase error rate.

You can ballpark the required voltages using AIDA stress test with cache and memory checked (+/- FPU depending on cooling). Should run it at 30min to an hour at the beginning of the process. This is more or less one of the first steps in cm87's guide on computerbase.de.

Otherwise, here is a 3200MT/s result for a Zen+ on the X370-Pro using FlareX B-die, although it is under Pinnacle AGESA v 4011. In this case, working RTT was 5-off-5. Forum post was at hardwareluxx.de here, via google translate. Maybe that will work for you, but that can be board, bios version, combination specific.

Ok thanks for this, already tried raise vcore but no help (im sure my cpu is stable, passed intelburntest 10 pass many times, p95 small fft, large fft, never crash)
About the RTT value, that's interesting, ive tried RTT NOM 34/off RTT PARK 48 and RTT WR OFF, gonna try different combination of RTT and let's see. thanks
Im actually maximum LLC for SOC, it dont overvolt, it just flat, 1.1v idle like full load, no any drop, but i could down it 1.1v is a bit high i agree (auto voltage)
This is my new timings, i dont really think its gonan be stable, but let's try

Op, have you tried swithing your rams placements? Put one in A2 to B2 and the one in B2 to A2.

Might be worth trying the other 2 slots as well.

Too much vcore will give you the same thing. Same as too much SOCv. Same with too much DRAMv. A single error can be voltage slightly off. Have you tried lowering SOCv to 1.88v?

Single error also try tRFC adjustment.

Im right now to 1.05v soc, i was 1.1v before. Ive got single error even with TRC 73 and TRFC 560 (auto timings, see picture post above) dram voltage 1.35v.
Buiut it seems more i raise vcore, more error pop late, i was to 1.312v and now to 1.325v
These are my auto timings and not even stable with that, 1.1v soc, dram 1.35v
