Hello,
 
Comme vous l'avez vu dans le titre, j'ai 2 x 16 Go qui sont devraient tourner à 3600 MHz sur mon PC et je suis en réalité bloqué à 3200 MHz.
 
Config :
 
i7 8700k
MPG Z390 Gaming Plus
 
 
Sur CPU-Z : DRAM Frequency 1600 MHz
 
J'ai activé le profil XMP dans le BIOS mais je suis toujours à 3200 MHz.
 
Je suis cap ou j'ai raté quelque chose ?
 
Bien à vous

Tu as un unique profil XMP ? Tu es sur que c'est bien de la 3600 (que disent le profils XMP dans CPU-Z par exemple ?).

 
Dans le BIOS je n'ai qu'un bouton "ON/OFF" du XMP et si je clique droit sur le XMP dans les paramètres avancés, les profils 1 à 5 restent à 3200.

y'a écrit quoi comme ref sur la barrette? pcq de ce que je lis, c'est vu comme des profils xmp 3200 sous cpuz
 
 
apres, deux choses
 
- 125€ c'est un peu cher pour 2x16 3600 C18, à moins cher que ca t'as de la 3600 C16 (110€ mais pas RGB)
 
 
- 3600 c'est bcp pour des intel 9xxx, pas de garantie que le cpu tienne
 
 
- en mode safe, rabats toi sur 2x16 3200 C16, tu verras pas la difference

 
Elles sont déjà achetées et montées. Je cherche à comprendre pourquoi je ne suis pas en 3600 MHz comme indiqué sur les barettes.

pr cpuz ce sont des 3200 C16
 

 
donc retire les, et vérifie ce qui est noté sur l'étiquette
 
si c'est noté 3200 C16, cherche pas plus loin, y'a eu une erreur lors de ta commande

 
Ah effectivement je viens de m'apercevoir chez LDLC qu'elles existent en 3200 et 3600. Je les ai achetées en magasin, le vendeur à dû me filer les 3200.
 
Sujet clos du coup, merci du coup de pouce

 
Hum pas vraiment, c'est la 4 eme revision de SKL .

Ça tient pas en 3600 sur mon 9900K en tout cas . Même après des heures de tweak vccSA/Io, timings en manuel etc etc

Y a toujours de mauvais combo proc / cm / ram .  
 
Mais 3600 ça passe la plus part du temps.
