Need some Gskill 3466 RAM help

so I bought "G.SKILL TridentZ RGB Series 32GB (2 x 16GB) DDR4 3466 (PC4 27700) Desktop Memory Model F4-3466C16D-32GTZR"

I'm just trying to get it to run at the rated speed of 3466, I just can't seem to get it to take. These are the Samsung B die type I have them in A2 and B2 slots on the Motherboard. What timing settings should I put down to get them stable? I set it to the timing to the DRAM specs for safe and Nada ...The best it will take is 3066

Spoiler!

is VDDP the same as CLDO_VDDP in the Pic? I could not find a CLDO_VDDP named area.

DRAM Cal says CLDO_VDDP rec=700 alt=913 alt2=866.

Try increasing or lowering CLDO_VDDP by 2 in a step, after each shift you need to completely turn off the PC. I managed to get stability with CLDO_VDDP 370

Yeah, it's usually buried at the very bottom of the DRAM timings menu.

I don't know what the default is, but I put it at 700 and did my stability tests with that, so I'm leaving it for now.

If someone knows,

Would changing the VLDO_VDDP help with tightening sub-timings?

I'm at 3466 safe preset, but I'm having a hard time getting stability at the fast preset. I can boot into Windows and everything, but Linpack Xtreme with high memory usage fails after a few runs. TestMem5 passes easily though.

DDR4 voltage set to 1.45V or over instant instability

i have a X470 Taichi bios version 2.0
CPU R5 2600 (mine) and R7 2700X (on loan)
memory Samsung OEM b-die 2x 16G sticks inserted in A2/B2 dimm slots
reset bios to factory defaults, reset bios ... ....

if i go in bios and the one and only setting i do is DDR voltage set to 1.5V windows gives blue screen instantly when it tries to boot
DDR voltage 1.4V works fine
DDR voltage set to 1.45V also crashes
(i know that if voltage is set to 1.45 reported is 1.48V and if i set 1.5v reported is 1.53V)
i tried the memory on other MB brand model at 1.5V+ and works fine so it's not the memory
I tried 2 cpus on the x470 taichi the 2600 and the 2700x and the behavior is identical so it's not the CPU

can anyone else that has a x470 taichi can please try to set ddr voltage to 1.5 and above no other change (no xmp ...) and report back if his system is stable or not

Can anyone confirm if using the official bios 2.0 from Asrock's site that XFR can be enabled? Coz on previous versions my pc couldn't boot if I had XFR enabled.

cannot confirm i have my memory all set manually (my memory is OEM and has no XMP profile)
if you upgrade to bios 2.0 will be rely helpful if you could set ddr4 voltage to 1.5V and see if you can boot in windows, will help me a lot.
