BD82Q65 is the Intel ordering code for the desktop Q65 Platform Controller Hub in the Intel 6 Series chipset family. Intel's specification update identifies the B3 stepping as S-Spec SLJ4E. The PCH connects the processor platform to SATA, USB, PCI Express and legacy system interfaces.
Confirm the supplied device marking, stepping and board firmware against the platform design before assembly.
Intel's 6 Series/C200 datasheet identifies Q65 as a desktop chipset SKU. It provides eight PCI Express 2.0 ports, a PCI interface, fourteen USB 2.0 ports and six SATA ports. The Q65-specific feature table supports AHCI but not the RAID 0/1/5/10 feature set shown for Q67. The chipset does not itself contain a CPU or graphics processor.
Combines serial storage, USB and PCI Express connectivity in one PCH.
Intel's SKU table defines the specific Q65 port and management capabilities.
Board BIOS and chipset configuration select supported interface modes.
Intel documents B3 stepping as SLJ4E for BD82Q65.
Eight PCI Express 2.0 ports are listed for Q65.
Fourteen USB 2.0 ports are listed for Q65.
Six total SATA ports: one supports 6 Gb/s and five are limited to 3 Gb/s or 1.5 Gb/s.
AHCI support is listed; RAID 0/1/5/10 is not listed for Q65.
The catalog describes BD82Q65 as 942-FBGA, FCBGA. A current distributor describes it as FCBGA-942, 27 mm by 27 mm. The package workbook's 942-FBGA row includes this catalog label, but its referenced JPG is absent locally; confirm the manufacturer mechanical drawing and exact ball map before layout or replacement.

The registered JPG is missing; the illustration is not approved.
The Intel 6 Series/C200 datasheet is the authority for numbered ball assignments. Functional groups include processor-facing DMI, SATA, PCI Express, USB, display-related interfaces, LPC/SPI firmware connections, clocks, power and grounds. Do not substitute a generic BGA pinout for this exact stepping.
Direct Media Interface connects the PCH to the compatible processor platform.
SATA, PCI Express and USB signals route to board connectors and controllers.
LPC/SPI, clocks, reset, power management and interrupt signals support system startup.
Use Intel's ball map and electrical specifications to assign every supply domain.

Electrical limits, ball assignments and platform compatibility require the controlled Intel documents.
Another Intel 6 Series chipset is not automatically interchangeable. Q67, B65 and Q65 differ in storage, management or port capabilities. Validate ordering code, B3 stepping, firmware support, board routing, package ball map and platform qualification. No unverified internal substitute link is included.
Intel's specification update associates BD82Q65 with Q65 and S-Spec SLJ4E. Intel's 6 Series/C200 datasheet defines the Q65 feature column. Current distributor availability and lifecycle must be reconfirmed before procurement; catalog stock is not presented as a verified live distributor quantity.
Repair and support of qualified Q65-based platforms.
Supply planning for deployed systems using this exact chipset.
Maintaining SATA, USB, PCI Express and PCI functions of an existing design.
Controlled replacement after stepping and ball-map verification.
Check Intel top marking, S-Spec, lot traceability, BGA condition and storage history. For independent-market stock, request provenance and incoming electrical or functional test records. Verify all commercial terms and actual availability before placing an order.
Intel's Q65 desktop Platform Controller Hub; its B3 stepping is listed as SLJ4E.
Six, including one port supporting up to 6 Gb/s and five up to 3 Gb/s.
No; Intel's Q65 SKU column lists AHCI but not that RAID feature set.
No. The package register has a matching 942-FBGA row, but its referenced local JPG is absent.
Keep this detail under review until package artwork, exact mechanical compatibility, current authorized distributor inventory and tier pricing have been verified. Human approval is required before publication.
