X370 fatality it RAM help?

I need some serious help. I can't overclock my RAM at ALL. I've tried different timings, lowering speed, changing ProcODT to every setting from 43.6ohm to 96ohm. Changing command rate to 1T. Disabling gear down mode. This has turned out to be a bigger PITA than DDR3 to overclock. I'm begging, anyone who can help me out I welcome it.

Using x370 fatality it, 1800x, Trident Z RGB F4-3466C16D-32GTZR. Feeling pretty stupid right now.

Thanks, RAM just fails and drops to 2133mhz currently.

Sorry for sounding dumb, but by SOC voltage you mean VDDCR SOC voltage? And the only option it's freaking offset. So I have no idea what the current voltage is to set it to 1.1-1.2

It's not clear to me which board you have, is it the Fatal1ty X370 Gaming ITX/ac? It's the only one of the four ASRock Fatal1ty X370 boards whose name is close to what you posted.

I'll assume it is the Fatal1ty X370 Gaming ITX/ac.

Question, have you ever had this board and CPU pass POST yet, and go into the UEFI/BIOS? It seems you have at some point, how did you manage that?

The memory is listed in this board's memory QVL list. But G.SKILL's QVL list is all Intel chipset boards, so the XMP profile may not work well at all. Ryzen is not listed at all, which is surprising since this is a new model:

You said the memory won't do dual channel even at 2133. Have you verified that both DIMMs will work individually, one at a time in the board? Meaning that both DIMMs work, and one is not bad.

Disabling Geardown Mode forces a 1T timing, which is harder for the memory to do. This memory is probably DR (Dual Rank), meaning chips on both sides of the memory board, is that right?

You need to insert one DIMM at a time, into the A1 slot, and clear the CMOS/BIOS before you try starting the board. If you skip that step, you're just hurting yourself.

IF both DIMMs work individually, then try both DIMMs together, again clearing the CMOS/BIOS before starting the board. Sounds like you've tried that, but we need to know where you are at.

IF you get past 2667 with 32GB in that board, you'll be doing very well. Zero chance of getting the XMP speed of 3466 with 32GB. Stick with Auto memory settings for timing, ProcODT, etc, DRAM voltage at 1.35V. That memory should be Samsung B-die, so if you must set ProcODT, 53.3 ohms ONLY.

BTW, it's not you, its Ryzen and memory compatibility, its biggest issue. The only "you" problem is expecting more from Ryzen and this board than is practically possible.

The first thing you do when you have a problem is to take out all unnecessary parts. Now you learned it the hard way  ;)
