What the Core i3-370M is
The Intel Core i3-370M is a dual core Arrandale mobile processor from June 2010. It runs two Westmere cores at 2.4 GHz with Hyper-Threading for four threads and no Turbo Boost, backed by 256 KB of L2 per core and 3 MB of shared L3 cache. Power is rated at 35 W.
The 370M adds about 130 MHz over the 350M at the same 35 W. HD Graphics cover office displays. Against the i5-460M at similar base clocks it trails in single threaded bursts because Turbo Boost is absent.
Memory is DDR3-1066 in two channels up to 8 GB.
Socket and motherboard compatibility
The Core i3-370M fits Socket G1 with 988 pins. HM55 class boards boot it directly with a 2010 BIOS.
The Socket vs chipset: what decides whether a CPU works guide covers pairing rules, and the Intel Core i3-390M page shows a faster i3 on the same socket.
Memory, PCIe and cooling
Memory is DDR3-1066 in two channels up to 8 GB.
PCIe 2.0 x16 comes from the package.
Cooling uses the vendor heat pipe assembly rated for 35 W.
Upgrade paths
On Socket G1 the upgrade is a Core i5 with Turbo Boost or a Core i7 with 4 MB of cache. Beyond Socket G1 a move to Sandy Bridge needs a new notebook.
