Asus Z390-H Gaming: Double Start after cold-boot

[Game-Gun]

Hello Steam-Community,

i just finished building a Gaming-PC with the following specs:
MB: Asus Z390-H Gaming (used)
PSU Seasonic Focus GX 750W (new)
CPU: i7-9700 (used)
Ram: 32 Gb (4x8Gb) 3600mhz ADATA XPG SPECTRIX D60G (used)
Storage: 2xNVME-SSDs + 3 Sata-SSDs (new)
PC-Case: NZXT S340 Elite (used)
GPU: Powercolor RX 5700XT Red Devil (used)
Wifi-Card: Glotrends Wi-Fi 5 AC1200 (new)

The Problem:
Whenever the Pc does a cold-boot (switing off PSU or poweroutlet which the pc is connected to), the Pc starts the first time and goes off bevor the rgb of the ram has time to light up and goes off. The DRAM-Led appears to be light while this is happening. Bios-Screen also has no time to appear.
After the second boot everthing works perfectly normal and the pc boots into windows.
This does not happen as long as there is always power to the motherboard, even if erp (S4+S5) is activated in Bios.

Ich have made the following troubleshooting-steps:
i tested 4 different ram kids with and without XMP. I also tested 1, 2 and 4 sticks. I also tested every Ram-Slot with a single stick.
I enabled and disable erp with S4 and/or S5.
I disabled fastboot.
I removed the cmosbattery and reset everthing. Right after that i tried not using XMP.
I tried the different XMP-Profils for the Ram.
I swapped the PSU. The one currently used is the one that replaced a Rog Strix 750.
I tried all of the above without the Graficscard.
I removed my cableextensions, just in case there was a problem with powerdelivery.
I tried the board with only cpu and Ram and cooler and disconnected everthing else.
While not having the Graficscard installed. I used the HDMI and Displayport-Output.

I read in some Forumposts that this is a normal behaivior for Ausus Z390-boards, some even stating that all Z390 motherboards do that "doublepump". I do not believe that this is true.

Can anybody help me getting rid of this stupid doubleboot. Or does some know a Z390 Board that does not do this ♥♥♥♥♥♥♥♥?

Thank you very much for your help and sorry for the bad english.

My older AMD FX computer started doing this and I thought the fault was in fact the PSU but I was wrong. My issue was grounding the motherboard.

in bios power options, power settings, on power restore stay off

it can also be windows using hibernate/fast startup
start -> run as administrator -> cmd -> powercfg -h off
and reboot

Go into bios and select manual instead of auto for xmp profile and configure.

xmp has nothing to do with the ram leds

Might be a RAM related issue though. You really shouldn't attempt to use above 3200 for that Motherboard & CPU. Especially with all 4 DIMM slots populated.

Hello, thank you all for your helpfull input, i also tried just 2 sticks of g.skill Aegis (3200mhz) with and without xmp. The Problem is still there. I think i have no choice but to RMA. I tried a third PSU and put the Motherboard out of the Case, to make sure that there are no grounding issues, but nothing helped. The Last thing i could try is to Downgrad the Bios from Version 3006 (the latest) to something much older. I read in other Forum-Posts that other Asus-Motherboards had this issue and it was solved with Bios 0805. This Motherboard has a Bios with the same Name. I dont know if this even matters, but im running out of options and patience...

Yes, it can sometimes be best to use a lower BIOS. I recommend the most stable version for your particular system let it be the latest or even v1.

I thought it would be memory retraining
While it might be annoying, i think you might be going overboard for an annoyance and not a full on issue if everything works properly.

This. What could be happening is the PC is attempt to boot using your 3600 XMP: I doubt it can, so it reboots using something else.

It should be giving you a POST warning though usually if that is the case, such as OC'ing failed.

[Game-Gun]

no such warning, i even put a post code speaker in, to test if something is happening, but nothing, not one deep in the double boot process

[Game-Gun]

correction: after the scond boot there is a single short deep, which, i assume, means everthing is fine

Memory Training doesnt give an error code as far as im aware
But yeah, unless something was actually giving you problems id say you wasted money on a non issue.. but whatever works i guess

[Game-Gun]

RMAd it today, orderd an Asrock Z390 Phantom Gaming 7 on Ebay. Hope this one works better...

You probably have an overclock that needs training on every cold boot. My 11400f does this. When I overclock and perform a cold boot it will start training over again. Warm boot it doesn't.

Yup
