Chipset Intel® C612 - Thông số kỹ thuật sản phẩm
Key specifications
- Platform: Intel C610 series (Wellsburg); marketed as Intel® C612.
- Segment: Server / Workstation (discontinued for mainstream retail).
- Launch: Q3 2014 (product later moved to discontinued/legacy status).
- Process: 32 nm; typical chipset TDP ~7 W.
- PCIe: PCI Express Gen2, configurable x1/x2/x4; up to 8 chipset PCIe lanes.
- SATA: Up to 10 SATA ports (6.0 Gb/s).
- USB: Up to 14 USB ports (typically 6 USB 3.0 + 8 USB 2.0).
- Storage/RAID: RSTe support (Intel Rapid Storage Technology enterprise) and RAID capabilities tailored to server use.
- Network: Typically integrated 1 GbE provided by the board vendor; platform support for server NICs.
- Memory: Paired with LGA2011‑3 Xeon processors supporting DDR4 (server motherboards implement ECC).
- Manageability & security: Intel VT‑d, Trusted Execution Technology, Intel ME support (ME firmware versions varied by board), Intel Standard Manageability, Node Manager support on server platforms.
- Graphics: No integrated GPU output from chipset (CPU or separate GPU required).
Use Cases
- Entry/mid server: File servers, virtualization hosts for small-to-medium deployments.
- Workstations: CAD, content creation, scientific computing with multiple GPUs.
- Storage servers: Combined with SAS HBAs for HDD arrays and backup appliances.
Key Features
- Platform controller hub (PCH) role: Southbridge handling I/O, storage, USB, SATA, LAN (via discrete controllers or integrated MAC), LPC, SPI, and management interfaces.
- PCI Express: Up to 8 PCIe 2.0 lanes native from PCH for miscellaneous devices; main PCIe lanes provided by CPU (40 lanes typical from Xeon E5).
- Memory: Memory controller is on CPU (DDR3 ECC Registered/Buffered). C612 platforms typically support quad-channel DDR3 RDIMM/LRDIMM, ECC.
- Storage:
- SATA ports: Up to 8 SATA 6.0 Gbps ports (supports RAID 0/1/5/10 via Intel Rapid Storage Technology Enterprise (RSTe) on some boards or vendor RAID controllers).
- AHCI support and hot-plug capability (depending on board design).
- Some server boards combine C612 with additional SAS controllers (LSI/Avago) for SAS/SATA RAID arrays.
- USB:
- USB 3.0: Native support via integrated USB 3.0 controllers or via additional controllers on vendor boards (typical 4 ports).
- USB 2.0: Multiple USB 2.0 ports supported.
- Networking: C612 does not integrate Ethernet PHYs universally; server/workstation motherboards pair C612 with Intel I210/I350 or other NICs for GbE, and additional controllers for 10GbE as needed.
- Management:
- Intel AMT/vPro are not typically part of C612; server management achieved via vendor BMCs (Baseboard Management Controller) over IPMI/Redfish.
- Serial/SMBus, SPI for firmware, LPC for legacy device interfaces.
- Expandability:
- Multiple PCIe slots provided by CPU lanes for GPUs, RAID cards, NICs.
- Support for multi-GPU workstation configurations (depending on board power and lane allocation).
- Misc:
- Integrated HD Audio support via codecs on motherboard.
- TPM header support.
- Multiple USB headers, fan headers, GPIOs.
Key Native Features (2021 Perspective)
- CPU Support: Intel Xeon E5-1600 v3/v4, E5-2600 v3/v4, and the insane E7 v3/v4 lines. It also unofficially (or via hacked BIOS) supports Core i7-5820K to i7-6950X.
- Memory: 8 DDR4 DIMMs per CPU (up to 1TB total), supporting Quad-Channel DDR4 2133/2400 (v3/v4 respectively).
- PCIe Lanes: The chipset itself provides 8 PCIe 2.0 lanes, but the CPU provides up to 40 PCIe 3.0 lanes. This is critical.
- Storage: Up to 10 SATA 3 ports (6 Gbps) + support for SATA Express.
- Legacy: USB 3.0 (not 3.1/3.2), 14 USB 2.0 ports.
In 2014, this was a monster. In 2021, it looks dated on paper—but specs don't always tell the whole story.
