Pls help to squeeze all of Samsung B-die Kingston HyperX Predator 3333 2x8 kit

Hi all! It's my first thread here (except of one introductionary one i started in the wrong branch by accident). I'm pretty new to overclocking and for now looking for 24/7 safe overclock for my new rig. Maybe soon i will try something extreme, you never know!

What do we have?
CPU: Ryzen 7 2700 with Noctua NH-D15
Mobo: X470 ASUS PRIME-PRO
RAM: HyperX Predator 16GB (2x8) kit (HX433C16PB3K2/16) with Samsung B-die chips
Rest of components are not so important for CPU and RAM OC i think

CPU works fine on 4000MHz 1.275v (Manual) and LLC2. Stable in OCCT Linpack 2019 on all 16 threads. Intrested also what is the best safe 24/7 overclock for it. Voltage must be safe according to all info I found. But maybe it will be better to use offset voltage instead of manual? 1smus's RAM overclocking guide says that RAM can be unstable with highly overclocked CPU ~4200MHz.
Managed to start RAM on 3499MHz CL16, using timings and V2 profile from DRAM calc (pics below), 1.39v and 1.025 SOC (LLC2). Latency 70 ns is pretty high.
Didn't POST with CL14 timings from profile V1.
TestMem5 on default config passes without errors.
I have read about that RAM kit it sucks in overclocking although it has samsung b-die chips, maybe because it has maximum factory overclocking.
Any thought how i can boost my performance on these for safe 24/7?
I ordered G.SKILL Sniper X 3600C19 kit, will test it later. Now i want to know what current kit is capable of.

It's doing fine, with my Kingston 3600 I managed all the way up to 4000MHz but memory scores were worse than at 3600. For one, Cl won't go under 16 and that's with 3700x. Best Aida score was at 3733MHz but with 70 mS latency, that's the part I couldn't get any better.

Kit also POSTed on 3600 clock and CL16 timings from calc, but had like 6 to 12 errors in TM5 default config test. Maybe if I debug some timings I will reduce that error count. Latency and bandwidth also was better than on 3499.

Did you try with 1.4v for RAM ?

It's a miracle you can boot at 3499 with Ryzen 2700. Manually tighten your timings in bios and that's all. You sure this kit is B-Die?

Yep, also tried voltages between 1.35 and 1.4, errors still present. I think it's about timings.

Why do u think so? I know that official supported memory freq for ryzen 7 2700 is 2933MHz in dual channel, but it works even on 3466MHz and can run above if motherboard is good enough. Memory controller's microcode in CPU can change with AGESA updates.

Because it's still a miracle to boot at 3466MHz with Zen + CPUs.

No it isn't given right combination of MB, BIOS and RAM. I had it running at 3600MHz Cl 16 even with 2700x, it even gave a bit better scores than now with 3700x.
