Asus Rog Strix Z790-A gaming WiFi II can’t boot with 2 sticks of RAM

MihaiE

I have an issue on my pc, asus rog strix z790-a gaming WiFi 2, I’ve tried 3 types of rams (Corsair Titanium, Corsair Vengence, Kingston Fury). With none of them don’t boot with 2 sticks in slots A2 and B2. It will boot with a single stick in B2 slot. If I try to boot with one single stick in A2 the yellow led on mobo stays on. I think the slot A2 from my motherboard is busted. I don’t know what to try next :))

cpu : 14900k

gpu : asus rog strix 4090

 Hello MihaiE

Try updating to the latest bios and see if this gets the A2 memory slot working, the latest bios for your motherboard is 0801.

ROG STRIX Z790-A GAMING WIFI II | Gaming motherboards|ROG - Republic of Gamers|ROG Global (asus.com)

A memory slot not working can be due to an overtightened cpu cooler or bent/misaligned cpu socket pins.

Try loosening your cpu cooler a little.

If no help, remove the cpu cooler and cpu and check carefully for any bent or misaligned cpu socket pins.

 

 

 

 

 

Thank you for your response in the first time.

I have the last bios which I’ve downloaded from asus.com 0801.

i will try later when I reach home to loosening the cpu cooler a bit to see if I have luck, and then check the cpu on  intel’s 14900

Great !

Give us an update anytime.

If loosening the cooler doesn't help, you can take a picture of the cpu socket and post it here for us to check if you like.

 

 

 

Definitely. 
I will try both solutions, and I will come with an update.

Unscrewed everything (aio, contact frame, clean everything) screwed everything back , repaste the cpu, place the aio back but not so tightened and the pc post with two sticks of ram, and xmp profile as well.
