Socket LGA 1851 et chipset B860

Cette carte mère ATX accueille les processeurs Intel Core Ultra de série 2 via un socket LGA 1851. Le chipset B860 gère quatre emplacements DDR5 jusqu'à 256 Go en dual channel avec profils XMP 3.0 et prise en charge des CUDIMM. Un slot PCIe 5.0 x16 et un second slot PCIe 4.0 x4 assurent l'extension graphique et additionnelle.

Alimentation 10+1+1+1+1 Dr.MOS

L'étage d'alimentation utilise une conception 10+1+1+1+1 phases avec Dr.MOS pour le VCore, le GT et le SA. Quatre connecteurs SATA 6 Gbit/s et trois sockets M.2 (un Gen5 x4 128 Gbit/s, deux Gen4 x4 64 Gbit/s) complètent le stockage. Le contrôleur Dragon RTL8125BG assure le réseau 2,5 Gbit/s et le codec Realtek ALC897 délivre un son 7.1 canaux.

Accessoires fournis et logiciels

Le bundle comprend un cache I/O, des câbles SATA, des vis pour M.2 et la documentation. L'utilitaire ASRock Polychrome SYNC pilote l'éclairage ARGB et RGB adressable. Le BIOS intègre Intel VMD pour la gestion NVMe et la mise à jour instantanée Instant Flash sans clé USB.

Spørgsmål om denne vare

How do I install the CPU into the LGA 1851 socket without bending pins?

Lift the socket lever, align the processor triangle with the socket corner, place the CPU gently without pressure, lower the frame and lock the lever; the common mistake is forcing the chip before the frame is fully closed.

What upkeep does the 10+1+1+1+1 Dr.MOS power phase design require over time?

Dust the VRM heatsinks and chassis fans every few months; the Dr.MOS stages have no user-serviceable parts, so no thermal-pad replacement or firmware action is needed unless temperatures rise unexpectedly.

Which limit appears first when the Blazing M.2 socket runs at PCIe Gen5x4 128 Gb/s under sustained writes?

The SSD controller typically hits its thermal throttle point before the motherboard lane saturates; adding a heatsink to the M.2_1 drive keeps sequential throughput stable.
