I have a x470 Taichi running the latest beta bios 3.82. I've tried 3.77 as well.

I had 2 x 8gb gSkill flare x 3200 c14 running happily and tuned to the fast preset. It was even at 3466mhz at one point. I purchased another 16gb last week taking me to 32gb total.

My issue is the PC will simply not boot with all 4 sticks populated. Even when pegged at 1866mhz it will not boot. At this point it would be great just to boot into Windows with all 4 dimms. I have changed the sticks around but no go.

When I remove one stick, leaving 3, it will boot at 3200mhz fine into Windows.

I have tried upping the voltage to 1.4, soc to 1.1, VDDP to 1.1.

I am using the Safe preset as below. Any ideas?
Hi again, anyone got any ideas? I have tried multiple bioses, 4 populated dimms simply will not boot, even at the lowest and loosest settings.

I have a MSI Tomahawk B450 with 4 dimms working fine in my server box, with slower memory.

On the weekend I am going to try that 4 x 16gb from the Tomahawk in the Taichi and vice versa.

Overall not impressed with the Asrock, the bios leaves a lot to be desired.

ambivalence_ru hey, guys.

could you please tell me if it's okay to have 14-(15-14)-14-28 timings? I couldn't get my dual-ranked samsung b-die below the second 15 (tRCD RD), the others are completely fine. the thing is that as far as I know tRAS (mine 28) = tRCD + tCL (the first 14), but tRCD has two numbers: 15 for reading and the next after 14 for writing. so, is it okay to set 28 because most of numbers are 14 or should I leave it 29? I also haven't tried to push 14s to 13s – is there a point to do it, leaving the second number 15?

I found this discussion relatable, but the question remains what is the best tRAS setting taking into account that tRCD has two values one of each can go pretty low.

chevy350 Here's what I've gotten so far with F4-3600C16D-32GTZNC, probably a little more room for improvement but overall satisfied for what I've gotten with the help of the calc

Ah, I misspoke, I was referring to the DRAM calculator

1usmus recommends 40 Ohm max for Zen 2 in this thread, but his DRAM tool doesn't reflect that.

Cool....

I was able to tighten the timings a bit. All I changed were the timings. I didn't touch any of the other settings(ProODT/CADBUS/ETC). A little bit better, but not much. For mismatched sets of ram though, I'm pretty happy.

I guess you missed this screenshot:



There is no 40 Ohm suggestion as you can see, in which case you will experience POST issues. That was my point.

EDIT: It does shows it as CJR. +Rep

EDIT II: Same results....if I change anything/everything with the timings, I end up in a endless boot cycle, or auto repair...
