Cannot POST using 3600Mhz / 3533Mhz / 3466Mhz - RMA CPU?

EDIT:

I am convinced this is my CPU !! I am unable to POST with the default DOCP profile at 3600Mhz / 3533Mhz / 3466Mhz !!!

Should I just RMA the CPU? Because at this point, this is an absolute joke.
------------------------

Does Ryzen only work with 3200Mhz memory? Because that's the consensus I'm getting here with my 3600Mhz ram kit as well as what I'm reading from others. I am using the DRAM Ryzen calculator and it's still crashing my computer when it goes to sleep, although not often, occasionally.

FCLK @ 1800
All the timings below + subtimings
SOC voltage left on auto @ 1.025V
DRAM voltage 1.36V
Memory Frequency on auto

I've found better success with not touching the Termination Block Ω, CAD_BUS Block Ω, and CAD_BUS Timings settings. Leave them on auto and let the AGESA code figure it out. Punch in all the other stuff including the voltage recommendations. Be sure to go to the Advanced page and enter the voltage recommendations from there. I don't know if it's still needed, but power down and pull the power cord for 30 seconds after every change, so the memory retrains on the new settings.

Personally I would take the app's recommendation with a grain of salt..

Best is leave all other sub timings to auto and just adjust the main timings such as TCL, TRCDWR, TRCDRD, TRP, TRAS and TRC..you may also look into disabling Power Down mode..

I have the Vengeance LED 32GB kit b-dies on 3600 CL14 w/o issues having to resume from a sleep..also check if the power saving stuff for AMD is enabled and your CStates/PStates as well..

If you still find trouble, might be best to check if there's an updated BIOS for your board and might as well update to it and after the update would be the best time to do a CMOS reset to get things back to default before you start tinkering again..

What ram slots are you using? a2,b2 for ryzen cpu's had the same issue because i was using the a1,b1 slots on my motherboard. Also you might wanna do something about that trfc timing. My ram kit is worse then yours so i dont see why you would have an issue. I can push tighter timings @ 3800mhz with this kit, but I never throughly stability tested it and I had to add so much more soc voltage and ram voltage to get it working so i stuck with 3600mhz@1.39v and auto soc.

I think for Daisy chain boards its on A2-B2 since its advised/mentioned in the manual..unless he did not read..

Well, I am using slots B2/A2 and haven't read of issues with users using the same slots. My board, listed below, recommends that on the board (daisy chain.)

My Specs:

Ryzen 7 3700X
Asus TUF Gaming X570 board
2x 8GB F4-3600C16D-16GTZN (B-die)

Up this to 1.4-1.45v even 1.5v would be fine with some airflow and may allow for 3600c14 with a little work\luck.
Worth trying 1.05-1.1v SOC just to see if it helps.

Will do, I also came across users that updated the BIOS to support the latest Zen 3 CPUs have issues with OC'ing and it being completely broken. Not sure if there is any truth to that.

In my limited attempt to OC in BIOS my benchmarks went down. AMD has really tweaked the CPU already for best gaming performance. Very little headroom in OC but lots of extra heat.

doing all core OC will just hurt performance(single threaded work loads including gaming)..AMD suggests you use PBO instead and tweak stuff from there..

I also never have had any luck messing with cad /bus settings (the ohms) that the calc suggests . They likely work great with the mobo's 1usmus used when designing the program but not mine nor the ram kits ive used .

I had 2700 non x and now 3600x. My mobo (gigabyte) has alot of redundant menus in the bios. 3 diff area's where ram timings can be set . 4 (inc prev 3 mentioned) spots u can change ram Freq Multiplier.

Witht he 2700 i could simply change timings in the first memory menu with timings listed np no matter what bios.

The 3600x however isn't the same , I have to edit the timings in a menu that accepts only Hexidecimal entries (why this is a thing ? no clue ...utterly worthless implementation of a code end users have zero use for when it comes to using a Bios)

pay attention to TCKE / TRCD <-- (d) TwrrD , TRDWR those 3 settings in particular for whatever reason across three different hynix cjr kits ive tested /used across two zen processors the calc gives settings that won't work or at best bsod randomly .

Hynix (1 kit i had TCKE = 1 np) other two I had to set it to 2 and 6 respectively. TWRRD I had to set to 3 on ALL three kits on both cpu's no matter Freq i shot for. TRDWR 9 in all 3 cases where as calc suggest 1 and 8? or 1 and 7 possibly. but 1usmus does mention this behavior with twrrd in his article u should read prior to using the calc. Cad bus timings etc worthless to tinker with in my experience with the hardware ive had. Calc will take a trashy cjr with a 3200 xmp of 16/18/18/18/38 and suggest 16/17/16/19/34 ...why? im unsure but this tends to crash in certain games even if passing mem test and aida. 3400 mhz 16/18/16/18/32 ....no problem 3333mhz 14/18/14/18/28/42 even in one case i had np with but that 16/17 and trp at 19 combo it suggests so often is garbo for Gigabyte x470 board anyway.

No issues to report with my setup. All stock 5800x with 3600mhz Gskill 16gbx2 16-16-16-36 (F4-3600C16-16GTZN) auto voltage

I have the same setup as you. I have the xmp profile on and i have have now the clocks at 3733 and fclk 1867. Works fine without touching anything else! Before that i had issues at 3600 and it solved with the latest beta bios from msi. (b550 gaming carbon)
