Hello les boyz et les girlz    
 
J'ai récemment acheté une Z690 Asus rog Apex sur le forum avec un kit de DDR5 G.Skill Trident Z5 RGB DDR5 2x16Go 6000C36 tRAS96 Noir et un i9 12900K.
 
La carte boote sans problème avec n'importe quel stick mais uniquement dans le port proche du dimm2. Une fois booté, 0 erreur, 0 plantage, RAS ,tout va bien memtest OK.
 
Mais si je veux booter avec les 2 sticks , rien à faire, je reste bloqué à erreur 55, pas de ram inséré. Il arrive, dans de rares cas, que la carte mère démarre avec les 2 sticks mais aléatoirement. J'ai attendu patiemment que de nouveaux bios arrivent et règlent le problème mais en vain. Ca fait 2 bios nouveaux que je flashe, mais le problème persiste.
 
Que la RAM soit en 4200 ou en 6000, c'est pareil.
 
Je sèche du coup. La ram est bien compatible avec la rog apex selon asus      

La carte a connu le LN2 ? Possible qu'un slot ait pris l'eau

pas à ma connaissance...

pas sûr de ce que t'as fait donc je precise,
 
par defaut il faut mettre les rams sur les slot 2 et 4 (lecture de gauche a droite)
 
 
un seule barrette c'est sur le slot 2,
 
pas de risque d'avoir abimé le socket en installant le cpu ?
 
 

C'est une Apex, donc 2 slots
Ta remarque sur l'installation du CPU est pertinente.  
zeitoon, as-tu installé un support de socket aftermarket, type Thermalright ?

 
mea culpa  

salut
 
j'ai eu le même problème avec une maximus xi gene et dans mon cas c'était un pin du socket cpu tordu

non j'ai eu connaissance du support apres... mais parfois ça fonctionne...

ca passe en sav selon vos REX ?

si pas de pin tordu, ça passe en SAV

ok j'ai commandé le support socket : je vais checker tout ça !

For anyone here with a Z690 Apex
90MB18I0-M0AAY0
90MB18I0-M0EAY0 (November 2021)
that has written it off due to the A Channel being complete crap. I need you to try one thing that has brought my Z690 90MB18I0-M0AAY0 back from the depths of hell. The A Channel is Super sensitive to ram seating. I could not get my 90MB18I0-M0AAY0 Z690 Apex to OC over 6000mhz. I just thought I had a bum board as documented in Igors lab One Motherboard, Two Faces - ASUS ROG Maximus Z690 Apex review with Teardown, RAM- & Adaptive Core-OC | igor'sLAB (igorslab.de) . I was ready to write it off and wait for Z790. And then one thing that bugged the heck out of me.....The B channel, (when seating ram) would just "click" in. The Tabs on the North and South Side (being wide open before installation) just worked. It was like hearing a shotgun being loaded. You just placed your ram in that slot and then applied pressure to North and South and Bang Bang. It just pressed into the appropriate place. You can actually hear the "click" , "click" as it seats the ram. My A Channel was never this way. I approached the installation on the A Channel the same way as the B Channel but never got that "perfectly positive seating". I thought that I was applying enough pressure but never had that positive "click" in as I did with the B Channel. I ran my system for almost a year in this way. I thought I was lucky to have an Apex that did 6000mhz seamlessly. It seemed to seat perfectly, but ...alas. No Bueno. Whenever I tried to OC the RAM....Sh*tsville. I just chalked it up to no patience and no skill. I literally fu*ed with this slot for over 10 minutes last week and felt the Ram Stick move lower than I thought it should go. After this maneuver my A slot is doing 6800mhz passing ram tests when it was intermittent at 6000mhz. I've had this board since Dec 2021 and the whole time My A Channel Ram wasn't appropriately seated. Can you believe this complete cluster fu*? I didn't want to post this 5 minutes after discovery but waited a week to do Ram testing on MemTest86, Kahru, TestMem5. Passed 5 hours of each. ***!? I am a happy camper now and can't believe that having my Ram in the A Channel at 99.5% seated compared to 100% seated made the difference. You would have thought that if your Ram wasn't seated appropriately that it would have bunked out massive errors immediately. We've all heard of this kind of situation with novice builders and would never, ever think this was a possibility with most of us but if this post helps at least 1 of you out there that think you have a complete crap Z690 Apex........screw with that A Channel seating......it literally saved me from buying and rebuilding my PC!

Merci, je vais retenter l'installation : mon support thermalright arrive ce jour  

Bon et bien merci la communauté tout est ok grâce à l'adaptateur . Aucun pin de tordus en fait c'était juste le verrou du socket d'origine qui forcait trop...
