Unable to enter BIOS on first boot GIGABYTE Z790 AORUS ELITE AX MB

[DC42]

Hello,

Putting together a new build on the bench (not in chassis).

CPU:Intel Core i7-14700K

CPU cooler:Noctua NH-D15S

Motherboard:GIGABYTE Z790 AORUS ELITE AX

Ram: G.SKILL Trident Z5 RGB Series 64GB (2 x 32GB) 288-Pin PC RAM DDR5 6400 (PC5 51200)

SSD/HDD:SAMSUNG 870 EVO Series 2.5" 1TB SATA III V-NAND Internal Solid State Drive (SSD) MZ-77E1T0B/AM

GPU: Onboard

PSU:Seasonic VERTEX GX-1200, 1200W 80+ Gold

Chassis: Not in yet

OS:Not installed yet

Monitor: Dell 22" HDMI connected via HDMI for initial set up

Turned on PSU. Board initially lights up, CPU cooler fan spinning, RAM lights are glowing, keyboard via USB is does not display light activity, monitor is not getting signal. The board is getting power but cannot get to the next step of hitting DEL and entering BIOS. CPU cables are secure from board to PSU, same with the board power cable.

Little DRAM light on the side of the board is flashing up and down. Tried to boot with one stick instead of two (32GB per stick). CPU dropped in nicely, secured it, and installed cooler. Want to get into the BIOS to check things out and then install Windows. I am stuck at this point. Pulled out the CMOS battery and placed back in to no avail. Believe the CPU and RAM are compatible based on the compatibility listings at the Gigabyte site. Any thoughts?

I tried a few more times and it posted ultimately ending up in the BIOS (then installing Windows). Had to use one stick in "3rd" slot (have to look the manual for slot info A or B, 1 or2).

Want to get dual channel going with my second identical stick. When I try I do not end up getting to Windows. The manual was clear on what slots to use but nothing seems to work for me. Need to investigate the BIOS and perform a deep dive.

Once I can get into using the desired 64GB of RAM all will be well.

Everything is fully updated (BIOS to version FJh, drivers installed, and Windows updated). Need to get my second identical memory stick in and configure the RAM to work in dual channel booting to Windows. More fun tomorrow.

Greetings,
RAM can be finnicky.  I wouldn't necessarily run a beta BIOS unless I absolutely had to.  Keep in mind that the latest available isn't always best.
