CPU +Ryzen 9 9900X

  • Ready-to-build combo with Ryzen 9 9900X and X870E board
  • 12 cores and 24 threads reach 5.6 GHz max boost
  • DDR5 memory scales to 8200 MT/s overclocked across four slots
  • PCIe 5.0 x16 plus triple M.2 with one Gen 5 slot

Combo AM5 X870E pour Ryzen 9 9900X

Ce pack associe la carte mère MSI X870E GAMING PLUS WIFI au processeur Ryzen 9 9900X à 12 cœurs et 24 threads. L'ensemble est conçu pour les stations de travail et les configurations de jeu haut de gamme qui exigent une bande passante mémoire et E/S maximale sur plateforme AM5.

Remplacement d'une base AM4 ou AM5 d'entrée de gamme

Le saut est pertinent quand vos charges de travail saturent 16 lignes PCIe 4.0 ou que la mémoire DDR5 JEDEC 4800 MT/s limite le débit. Le chipset X870E débloque le PCIe 5.0 x16 depuis le CPU et autorise l'overclocking mémoire jusqu'à 8200 MT/s en 1DPC 1R.

Vérifications avant commande

Confirmez que votre boîtier accepte le format ATX et que l'alimentation fournit les connecteurs 12VHPWR ou EPS 8 broches requis par le 9900X. Prévoyez un ventirad AM5 adapté au TDP du processeur, car aucun n'est inclus. Choisissez des barrettes DDR5 non-ECC compatibles EXPO pour atteindre les fréquences visées.

Questions about this item

What clearance does the AM5 socket area need for a CPU cooler on this board?

The board uses the AM5 socket; choose any AM5-compatible cooler that fits your case height limit and does not overhang the four DDR5 slots or the M.2_1 heatsink.

Which step is often missed when installing the Ryzen 9 9900X into the AM5 socket?

Align the gold triangle on the processor with the socket marker, lower it gently without force, then lock the retention arm; skipping the alignment check can bend pins.

Which component on this motherboard will need a driver update for full Wi-Fi 7 performance?

The onboard Wi-Fi 7 module requires the latest Windows or Linux wireless driver; install it after the chipset drivers to enable the 320 MHz channel and 5.8 Gbps link speed.
