Question Gigabyte B650 DS3H - No display, no beep, no POST ?

[Artamys]

Hello !

Firstly, let me apologize for my poor english, as it is not my primary language.

I've recently bought a complete setup ( not a prebuild ) on advices, but I can't manage to boot it..
I don't have any display, the monitor seems to not even wake up ( it's perfectly working rn with my laptop on both HMDI/DP).

Here is the full spec, everything is brand new :

CPU : AMD Ryzen 5 7600X 4.7 GHz 6-Core Processor
CPU Cooler :Thermalright Peerless Assassin 120 SE 66.17 CFM CPU Cooler
Motherboard : Gigabyte B650M DS3H Micro ATX AM5 Motherboard
Memory : Corsair Vengeance 32 GB (2 x 16 GB) DDR5-6000 CL36 Memory ( exact model is CMK32GX5M2B6000C36 )
Video Card : AMD Radeon RX 6950 XT Radeon RX 6950 XT 16 GB Video Card
Case : Fractal Design Pop Air ATX Mid Tower Case
Power Supply : NZXT C850 (2022) 850 W 80+ Gold Certified Fully Modular ATX
Here is the partpicker if needed : https://pcpartpicker.com/list/K2n9Vw

My first though was the ram at fault. I then realised on the (non exhaustive) list of compatible RAM from gigabyte site for this mobo, that this model (CMK32GX5M2B6000C36) was not listed. Some really similar models are, but not this one. Here is the list : https://www.gigabyte.com/Motherboard/B650M-DS3H-rev-10/support#support-memsup

I asked Corsair if it was compatible, they answered "It was not tested, ask Gigabyte", what I did. Gigabyte answered " When the RAM nnot in the QVL we cannot guarranty if it works fine with this MB.
But it would works with default BIOS setting. For your issue might relate on the GPU, it might not support the UEFI mode. ". Problem is I have no spare graphic card to test.. and don't really wanna buy one for !

I instead bought something a bit cheaper, a little speaker to hear my mobo crying. Result : no beep at all. I did it hastly (hoping for an answer) so it might be my bad on that point though. I'll try again later with only CPU and no GPU/RAM, only did it with CPU+cooler+GPU+RAM and obviously PSU.

Do you have any ideas about my problem, could it be tests or more informations !

Thank you in advance
EDIT : I forgot to add that the whole thing powers on, fans are running, the big red "RADEON" on the graphic card is lighting.

Hello !
Thank you for your fast answer. I stupidly pressed enter so my message sent before I finished it
Please find the full spec in the original post.

Im going crazy..
I removed everything but CPU, RAM and PSU.
I tried with :

1. CPU/2 RAM , CPU /1 RAM : no beep
2. CPU / no RAM : 3 "long" beeps ! Kinda one sec each
3. CPU / 1 RAM again : no beep
4. CPU / no ram again : 3 same beeps ! (edited bcs i'm retarded)

Did you find a fix to this? I'm also experiencing similar issues

Hello,

Yes I finally somehow managed to ''fix'' it by myself.

Mobo refuses to boot with a stick in the recommended slot for solo ( 2nd closest to CPU , A2 ? ), but is ok with one in the farthest ( B2 ? ). It also works with two sticks to the two farthest to the CPU.

I did a qflash+ before, but dunno if it's mandatory.

The whole thing boots in a really weird way.. It seems to boot once, then 2/3 sec after reboot to finally reach windows. Then computer works as intended.

The only exception is memory is set to 3600mhz by default. If I change the XMP in the bios to 6000 MHz, it boots but if computer is then shutdown ( seems at least for couple jours ), it refuses to boot at all. My only option is then to unplug it and empty it of electricity to reset bios config.

This memory stuff apart, it works fine. I've been fighting with if for over a month, I'm tired so I'm using it this way for the moment. If you find a fix or something, I would love that you share it with me

Hope it helps, and sorry for my English.
