Ok so I have had time to do some proper testing, and as I suspected my 3600 was not fully stable. I tried to fiddle a bit with some different settings on this speed but was unsuccessful.
Then I noticed @Gadfly post about his 3466 settings where he included all the timings and subtimings as well as his settings for voltage.
So I gave those settings a try, I did a 1:1 copy and fired up the machine.
I did a slight modification by bumping BCLK to 100.2 (because I am sick and tired of getting ~3893 MHz CPU speed, yes I know, I'm slightly pedantic) and reduced voltage all around just a little bit to see if it would work. And it did work beyond my expectations. Magic!

400%+ HCI stable. I don't know which of the settings did the trick in the end but combined they surely worked out nicely.
So went from 3200 C14 (with worse sub timings) on bios 9943 to 3473 C14 (with better sub timings) on bios 1401. This is a great bios indeed.
Using an 1800X. Ram kit is G.skill 2x8 3600 C16 (Part nr F4-3600C16D-16GTZR).

Using P-state OC with value 9C (3900 MHz).

Here are my general/voltage settings:
BCLK Frequency [100.2000]
Memory Frequency [DDR4-3473MHz]
Core Performance Boost [Disabled]
CPU Core Voltage [Offset mode]
CPU Offset Mode Sign [+]
- CPU Core Voltage Offset [0.02500]
CPU SOC Voltage [Manual mode]
- VDDSOC Voltage Override [1.11250]
DRAM Voltage [1.38000]
1.8V PLL Voltage [1.80000]
1.05V SB Voltage [1.05000]
CPU Load-line Calibration [Level 1]
VDDSOC Load-line Calibration [Level 1]
DRAM VBoot Voltage [1.38000]

Mem:
DRAM CAS# Latency [14]
DRAM RAS# to CAS# Read Delay [14]
DRAM RAS# to CAS# Write Delay [14]
DRAM RAS# PRE Time [14]

Full settings file attached as well as a screenshot of the HCI run.
Thanks a lot again to Gadfly for these settings. I will be looking around if you ever put out a 3600 C16 configuration.
And thanks to e@elmor @[email protected] for making this motherboard a great one.

That is great ram to do that with DDR @ 1.38v and with ProcODT at default. Check the post right above you by the Stilt for 3600 speeds. It might work.

3600MHz with ease, SWEET biggrin.gif , you ran some RAM stress tests yet?
Personally I'm using the recommended 53.3ohms by post-flame-small.gif Elmor post-flame-small.gif on my kit. Then for 3333MHz I use what post-flame-small.gif The Stilt post-flame-small.gif has used for his setup of 3466MHz on similar kit. 53.3 ohms sits about in the middle when I last checked for what me kit needs so I reckon the lowest may not be the best setting.



How low were you going on tRC?

There are some massive changes in the new PMU FW, which 1401 is using.
Based on my experience one step forward, two or three steps back.

While the new PMU FW allows hitting higher memory speeds, it can no longer handle running GearDownMode disabled w/ 1T or tightening of certain sub-timings (tWRWRSC, tRDRDSC, tWRWRSCL, tRDRDSCL). All of these are extremely important to the memory performance, which means that the new PMU FW is pretty much useless. It is not worth trading the significantly tighter sub-timings to slightly higher memory frequencies, especially when above 3200MHz the DFI is no longer a major bottle neck.

The correct ProcODT depends on various things, there isn't an "one size fits all" solution. The correct ProcODT depends on the DRAM ICs, DRAM PCB, CPU specimen, populated slots, etc.
AGESA defaults to 60Ohms for all configurations and 53.3 or 60Ohms is the optimal value for single rank Samsung B-die DIMMs (80 - 96Ohm for dual rank).

Sorry if I'm jumping to conclusions, but are you saying that above 3200+, latencies matters more than speed? And what does the acronym DFI stand for?

Based on my experience, definitely.
3520MHz 14-14-14-28-56-177ns (tCL-tRCDR/W-tRP-tRAS-tRC-tRFC) stands no chance against fully tuned 3200MHz 12-12-12-26-54-140ns (tCL-tRCDR/W-tRP-tRAS-tRC-tRFC) settings, everything else being equal.

DFICLK (Data Fabric). The fabric that connects the CCXs, memory controller and other blocks within the die together. It's frequency is tied to the MEMCLK (1:2 rate).

It seems like it. 1107 is still optimal for my hynix m-die lpx ram. Its fine at 3200 and HCI stable up to 700%. 1401 gets me to 50% then either errors like mad or blue screen crashes then sends me into an f9 boot loop. Considering how great it works now its totally pointless to even update the BIOS. its a real shame.

@YpsiNine

+rep, thank you smile.gif .

@The Stilt

+rep, thank you smile.gif .

Yep ProcODT I have grasped from your shares before, Elmor's, [email protected] and Praz smile.gif , but thank you again for further explanation thumb.gif .

I've stuck to 3333MHz on UEFI 1401. So far it benches in what I tried as 9943 on same setup plus is as stable. On 9943 using your 3466MHz timings I needed to tweak tRAS from 28 to 34, tRC 54 to 60, tFAW 36 to 39 and tRFC 333 to 373, for it to be stable on 3333MHz with 1.375V VDIMM and 1.05V SOC set in UEFI.

3200MHz I can use your 3466MHz timings setup with 1.35V VDIMM and 1.0V SOC set in UEFI on 9943 and 1401.

Are you able to share the fully tuned 3200MHz setup you have highlighted in same depth of settings as your 3466MHz setup previously posted? thanks smile.gif .

I will, as soon as I revert back to older bios.
3200MHz CL12 settings aren't very useful for most people, since only the best B-die modules can do those timings with sane voltages.
Even the very best modules require 1.45 - 1.50V to run 3200MHz CL12.

Strange, I'm using the same timings that you've posted some weeks ago with only faw at 28 and trc at 42 and I have no instability at 3466 14-14-14-14-28-42, 1.125 soc, 1.4 vdimm. I'll post the full timings once I'm back at my PC after work. It is GSAT and HCI stable by the way, 1 hour each.

Change attributes from 1 to 2

HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\0012ee47-9041-4b5d-9b77-535fba8b1442\dab60367-53fe-4fbc-825e-521d069d2456

And again change Attributes from 1 to 2.

Now go to Control Panel -> System and Security -> Power Options click on "Change Plan Settings" and then click on "Change advanced Power settings".

Now under "Hard disk" you should have AHCI Link Power Management - HIPM/DIPM and AHCI Link Power Management - Adaptive options.


Change "AHCI Link power management" To active, which means there is no power management for AHCI and finally change Adaptive to 0 milliseconds (Although if you enabled "active" this option has no effect).

Finally under "PCI Express" Change "Link State Power management" to OFF.

This solved my freezing problems.

I also did some test with the freezing scenarios:

first, I ran my pc bog standard (load optimize defaults) to rule out the overclocking being an issue. It turned out that full load in the non-overclocked system also led to freezes.
Then I tried above solution and since making the changes I have not had a pause yet! It's only been half an hour sofar, but before it would have paused by now.

Update:
Bit more testing shows that the system still freezes. Now using it's standard overclock (103X38 / 3300MHz memory @ 16/17/17/17/36)

No rush smile.gif . You help us plenty in many of AMD aspects thumb.gif .

Damn I sound like I'm your BITACH! biggrin.gif .
