What the Celeron G540T is
Intel Celeron G540T is a dual core Sandy Bridge desktop processor that Intel released in June 2012 for low power office towers. It runs at a fixed 2.1 GHz with no turbo and no Hyper-Threading, so 2 cores give 2 threads. Cache is 2 MB Intel Smart Cache. Power is 35 W on a 32 nm process. The list entry dating it to September 2011 is wrong; the Celeron list plus the Intel discontinuance notice place it in June 2012.
Graphics are Intel HD Graphics for Sandy Bridge at 650 MHz to 1000 MHz. The block covers office monitors and video without a card. The memory controller takes DDR3 at 1066 MT/s.
The 100 MHz step over the G530T at the same power suits quiet fleet refreshes. Boards pair it with H61, B75 or H77 and 4 GB of RAM. The LGA, PGA and BGA: CPU package types explained guide places this LGA desktop part against mobile forms.
Socket and motherboard compatibility
The Celeron G540T fits LGA 1155 in FCLGA1155 form. Both 6 series and 7 series boards boot Sandy Bridge directly. No update is needed for Sandy parts.
At 35 W slim office boards cover it easily. The Socket vs chipset: what decides whether a CPU works guide covers the chipset split.
Memory, PCIe and cooling
Memory support is DDR3-1066, two channels, up to 32 GB. Two matched DIMMs help the shared graphics block.
PCI Express is 16 lanes from the CPU at PCIe 2.0. Office builds usually skip a card.
Cooling is the 35 W stock pattern with push pins on 75 × 75 mm spacing.
Upgrade paths
On LGA 1155 the Celeron G540T can step to faster Celeron duals, Pentium duals and Core i3 chips on the same board. Memory and storage carry over. A slower T reference is Intel Celeron G530T on the same socket.
A platform move to LGA 1200 or newer needs a new board and DDR4 RAM.
