So these are al brand new parts, from yesterday 26nov

installed every piece of hardware like it should be,

now i tried to boot but it kept repeating : updating iROG-1,
so after looking op similar issues

flashed the bios to the latest : didn't solve it
tried kingston memory : Didn't solve it
tried different GPU: didn't solve it
tried different PSU: didn't solve it

at this point i have no clue what to do,

additional info :

Did you try switching to the second UEFI chip?

[HiVizMan]

Quick question and a possible way to fix it.

What was your shipping bios and how did your flash it?

Switch over to the B bios and get into BIOS and cross flash over.

i tryed switching to B Bios, and it kept rebooting and updating, i flashed with a usb stick no idea what original rom was

See the sticker near the motherboard's power connection. Tell us the last 4 digits:)

That's not the number we're looking for. See this for example:


See 1502 in the sticker? That's the version the boards ships with.

oh ok 😄 sry

4403

Download 4503 and try to flash that one instead. Use USB flashback. Nothing else.

well i have downloaded it and used USB flash, led's start blinking ... and after a lll that still nothing goes like this :

Start Button pressed
makes an attempt to start
shutsdown
startsup
waits for about 3-5min show the bootlogo (cannot press del or f2 no reaction either from USB board or PS2)
then i just shut it down cause it was like that for a whole night

also tried 1000w HX from corsair (thought it was due to not enough power) didn't solve anything
