Question new build no video

[dasschu]

Hi I just built the following

Gigabyte motherboard B670M plus wifi
Corsair 800e PSU
G.skill Trident Z5 RGB 64g RAM XMP
Ryzen 9 7900X3D
(basically the best builds of 2024 $2000 catagory)

1st MB was DoA - no video
2nd MB worked for a few days - until i turn on XMP. then no video output
3rd MB Gigabyte X870 Eagle plus wifi7. Worked for 1 day until i turned in XMP. it rebooted once then I turned it off right away and the next boot the MB had no video the lights on the MB confirmed an issue with the video. (rgb lights stop lighting up also)
I have built computers for years and never had such an issue.

Welcome to the forums, newcomer!

Corsair 800e PSU
I think you meant to say RM850e courtesy of Corsair. If not, please pass on a link to the PSU you're working with.

Gigabyte motherboard B670M plus wifi
I think you got the model for the board wrong as well. Please pass on a link to that as well.

G.skill Trident Z5 RGB 64g RAM XMP
People are advised to look for ram kits that have AMD's E.X.P.O advertised on the package to ensure maximum compatibility and stability. Got a link to the ram you're working with? Which slots are the rams populating on the motherboard?

How are you cooling the processor?

your right rm800e

the MB was a B650M.. sorry i've been looking at so many MB's the last 2 days.

RAM in A2 & B2 as recommended by Gigabyte

cooling..
Iceberg Thermal IceFLOE Oasis 360mm AIO CPU Liquid Cooler (never ran over 110 degrees when the system was working and i could see.)

110 degrees would be very concerning to me.
