What the Core i3-2310M is
Intel Core i3-2310M is a dual core Sandy Bridge mobile processor that Intel released in February 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.
Threaded office apps benefit from 4 threads even at modest clocks. The 2310M launched the Sandy mobile i3 line and appeared in many early 2011 laptops. Fixed clocks keep behavior predictable.
Graphics are Intel HD Graphics 3000 at 650 MHz to 1100 MHz. The block drives laptop panels and external monitors. The controller takes DDR3 SODIMMs in two channels.
Socket and motherboard compatibility
The Core i3-2310M fits Socket G2 with 988 contacts in FCPGA988 form. This page covers the socketed rPGA version. The same silicon also ships soldered on BGA 1023 for thin bodies, which is not a field swap. HM65 and HM67 boards carry early Sandy designs, while HM76 and HM77 accept Sandy parts directly.
The board BIOS must list the exact 2310M string. The Socket vs chipset: what decides whether a CPU works guide explains why the list outranks the chipset name.
Memory, PCIe and cooling
Memory support is DDR3-1066 and 1333, two channels, up to 16 GB. Matched SODIMMs help shared graphics. ECC is not supported.
PCI Express is 16 lanes from the CPU at PCIe 2.0 for wireless and storage. Most 2310M laptops stay on integrated graphics.
Cooling is a 35 W laptop fan assembly sized per chassis. Cleaning restores sustained clocks.
Upgrade paths
On Socket G2 the 2310M can move to the 2330M or 2350M for higher clocks, or to a Core i5 M with turbo where access and BIOS allow it. Storage and memory carry over. A nearby socketed reference is Intel Pentium B960.
A platform move means a new laptop. Keep the old body for basic tasks after wiping the drive.
Frequently asked questions
What socket does the Intel Core i3-2310M use?
It uses Socket G2 in FCPGA988 form. A soldered twin exists on BGA 1023.
Does the Core i3-2310M have Hyper-Threading?
Yes. Two cores give 4 threads. Pentium B parts of this era have 2 threads.
