Crucial DDR4 RAM 2666 MHZ not detected by the BIOS anymore with WIN11

Hi all,

I have a problem.

I added a 16 GB RAM CRUCIAL 2666 mhz in my asus motherboard from 2023. Everything was working well for weeks.

Now I checked in Win Task Manager Memory. I see that the memory is 16 GB and that the memory is not detected any longer.

Check the BIOS: 16 GB shown. The extra 16 GB CRUCIAL are not detected.

It happened after an UPDATE from WIN11 to WIN11.

Can someone help ?

Everything is plugged properly, i need to check the RAM bars indididually and clean the slots.

Any idea ?

P.S: i did the "Windows Memory Check" = no problem detected.

any tip is welcome...buy new RAM ?

Thanks in advance.
 
What happens when you remove old ram and only use new ram, does system boot? Perhaps the ram isn't fully seated in the slot?
 
Could have just failed, I have a gskill RMA currently for sticks from 2012 which won't run at XMP settings anymore.
 
Ok I tried to boot only with the CRUCIAL DDR4 (prolly defected). It failed. I will try it in a older motherboard to be sure it is a compatibility issue and not a dead RAM module. I removed the Crucial DDR 4 and stopped verifications. I wanted to take 0 risks as I have too much stuff in this computer to tinker more.

Thanks for your help all

Bye
 
Ok, I put the Crucial DDR4 2666mhz in a former Motherboard. Detected and working fine.
Compatibility wizzard. Mindf**k.
For info.
First time I encounter the "your RAM module is too old for this motherboard' Joke.
I guess, a start exist in everything. Amazing.
 
So what I am gonna do is to buy a twin AEGIS Gskill to match the 16 go one. Which is INSANELY CHEAP compared to the crucial.
Is it me or the price of the RAM decreases overtime...
Sad to buy cheap RAM when you had "high end" one...
Thx...
This topic is a monologue anyway.
We still have a problem of compatibility with mothership which is not heard of so far. (only one or 2 messages from 2020 on forums)
