What the Core i3-2312M is

Intel Core i3-2312M is a dual core Sandy Bridge mobile processor that Intel released in 2011 for socketed laptops. It runs at a fixed 2.1 GHz with no turbo and includes Hyper-Threading, so 2 cores give 4 threads. Cache is 3 MB Intel Smart Cache. Power is 35 W on a 32 nm process.

The 2312M matches the 2310M on clocks while appearing as an OEM option. Office behavior is identical in everyday suites. Intel lists the launch as the second quarter of 2011, so this page uses the year to avoid guessing a month.

Graphics are Intel HD Graphics 3000 at 650 MHz to 1100 MHz. The block covers laptop displays at native resolution. Memory is DDR3 at 1066 or 1333 MT/s.

Socket and motherboard compatibility

The Core i3-2312M fits Socket G2 with 988 contacts in FCPGA988 form. Intel lists PPGA988 as the supported socket. HM65 and HM67 boards from the Sandy wave carry it, and HM76 plus HM77 boards accept Sandy parts.

Board makers published the final CPU lists. A board that omits the string may refuse to boot even when the chipset matches. Check the list before buying a used laptop for parts.

Memory, PCIe and cooling

Memory support is DDR3-1066 and 1333, two channels, up to 16 GB. A matched pair helps shared graphics more than a single larger module. ECC is not supported.

PCI Express is 16 lanes from the CPU at PCIe 2.0. Lanes feed wireless, storage and card readers.

Cooling follows the 35 W mobile pattern with a single fan and a board specific heatsink. The CPU cooler compatibility by socket guide notes laptop heatsinks stay board specific.

Upgrade paths

On Socket G2 the 2312M can move to the 2330M or 2350M for higher clocks, or to a Core i5 M with turbo where lid access and firmware allow it. Memory and storage move with the board. A nearby socketed reference is Intel Core i3-2310M.

A full platform change needs a new laptop. Keep the old body for spare use.

Frequently asked questions

What socket does the Intel Core i3-2312M use?

It uses Socket G2 in FCPGA988 form.

How is the Core i3-2312M different from the 2310M?
