What the Celeron B800 is
Intel Celeron B800 is a dual core Sandy Bridge mobile processor that Intel released in June 2011 for low cost socketed laptops. It runs at a fixed 1.5 GHz with no turbo and no Hyper-Threading, so 2 cores give 2 threads. Cache is 2 MB Intel Smart Cache. Power is rated at 35 W on a 32 nm process with 504 million transistors on a 131 mm2 die.
Graphics are Intel HD Graphics for Sandy Bridge at 650 MHz to 1000 MHz. The block drives laptop panels and basic video without a separate card. The memory controller takes DDR3 SODIMMs at 1066 or 1333 MT/s in two channels.
The fixed clock keeps behavior predictable in classrooms and offices. Laptops pair the B800 with HM65 class boards, 2 GB to 4 GB of DDR3 and a spinning drive. The How to find your CPU socket type guide shows how to confirm the rPGA socket before ordering parts.
Socket and motherboard compatibility
The Celeron B800 fits Socket G2 with 988 contacts in FCPGA988 form. Mobile 6 series HM65 and HM67 boards carry early Sandy designs, while 7 series HM76 and HM77 accept Sandy parts directly. The board BIOS must list the exact B800 string.
Chipset choice matters less than BIOS coverage at this level. Any Socket G2 board that lists the B800 boots it at rated clocks. The Socket vs chipset: what decides whether a CPU works guide explains why the CPU support list outranks the chipset name.
Memory, PCIe and cooling
Memory support is DDR3-1066 and 1333, two channels, up to 16 GB. Two matched SODIMMs help the shared graphics block. ECC is not supported.
PCI Express is 16 lanes from the CPU at PCIe 2.0 for Wi-Fi, card readers and storage. Most B800 laptops stay on integrated graphics.
Cooling is a 35 W laptop fan assembly sized per chassis. Dust removal holds the fixed 1.5 GHz behavior under classroom loads.
Upgrade paths
On Socket G2 the Celeron B800 can move to faster duals such as the B810 or B840, to Pentium B parts, or to Core i3 M chips where lid access and BIOS allow it. Storage and memory carry over. A nearby dual reference is Intel Celeron B815.
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 Celeron B800 use?
It uses Socket G2 in FCPGA988 form.
Does the Celeron B800 have Hyper-Threading?
No. Two cores give 2 threads at a fixed 1.5 GHz.
