Intel Core i7-3630QM socket: Socket G2

What the Core i7-3630QM is

Intel Core i7-3630QM is a quad core Ivy Bridge mobile processor that Intel released in September 2012 as a late speed bump for socketed performance laptops. It runs at 2.4 GHz base with turbo to 3.4 GHz, with 6 MB Intel Smart Cache and Hyper-Threading for 8 threads. Power is rated at 45 W on a 22 nm process. The 100 MHz steps over the 3610QM mark it as a refresh rather than a new design.

Graphics are Intel HD Graphics 4000 at 650 MHz to 1150 MHz. The block handles office displays alone, while quad laptops of the period usually add a discrete GPU for 3D work. Memory is DDR3, DDR3L and DDR3-RS at 1333 or 1600 MT/s for up to 32 GB, with virtualization and AES for lab images.

Late 2012 laptops pair it with HM77 or QM77, two SODIMMs and dual drives. All core work sits near 2.4 GHz, while bursts reach 3.4 GHz for foreground tasks. The How to find your CPU socket type guide helps confirm the socketed package in a used workstation laptop.

Socket and motherboard compatibility

The Core i7-3630QM fits Socket G2 as an FCPGA988 part at 37.5 × 37.5 mm. No soldered twin exists for this SKU, so the board search stays inside Socket G2. The BIOS must list the exact 3630QM string with Ivy Bridge microcode, since late 2012 models postdate early Socket G2 firmware. At 45 W the chip needs a quad rated heatsink.

Mobile 7 series chipsets carry it, most often HM77 and QM77. Boards that shipped with Sandy Bridge need a firmware update before the swap. The Socket vs chipset: what decides whether a CPU works guide covers that order, and Intel Core i7-3610QM shows the close April quad on the same socket.

Memory, PCIe and cooling

Memory support is DDR3, DDR3L and DDR3-RS at 1333 or 1600 MT/s, two channels, up to 32 GB for 25.6 GB/s. Two matched 8 GB modules were the typical quad fit, feeding eight threads and shared graphics. ECC is not supported.

PCI Express is 16 lanes from the CPU at PCIe 3.0, split as 1x16, 2x8 or 1x8 plus 2x4. Performance laptops wire lanes to a discrete GPU plus SSDs and Wi-Fi. The integrated block drives the panel when switching saves power.

Cooling is board specific for 45 W with a 105 C junction class. Quad heat needs full pipes and clean fans to hold turbo. A repaste during service often returns the 3.4 GHz single core peak.

Upgrade paths

On Socket G2 the Core i7-3630QM already sits near the top of the 45 W QM group, so same socket moves are short. A nearby step is a faster late QM where the manual and BIOS allow it, with memory and storage carrying over. A slower quad comparison is Intel Core i7-3612QM, which trades clocks for 35 W.

A platform change means a new performance laptop on a newer BGA package. Keep the current quad for threaded work where eight Ivy threads still meet the load.
