What the Pentium D 830 is
The Intel Pentium D 830 is a 3 GHz dual-core desktop processor from May 2005. It runs two NetBurst cores at 3 GHz with no Hyper-Threading, so 2 cores give 2 threads. Cache is 2 MB of L2 as two 1 MB dies on a 90 nm process. Power is rated at 130 W on LGA 775.
The 830 served mainstream Smithfield towers on an 800 MT/s bus with a 15x multiplier at about 316 dollars launch price. It exists because buyers wanted 3 GHz dual cores without Hyper-Threading where the board cools 130 W.
Socket and motherboard compatibility
The 830 drops into LGA 775 boards with DDR2 memory and a BIOS that lists Smithfield dual cores, such as 945 boards. Boards need voltage regulator support for the 130 W envelope. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2 through the board chipset in two channels.
An 800 MT/s front side bus ties the CPU to the chipset. PCIe slots hang off the chipset.
Cooling is a 130 W rated LGA 775 heatsink on the 72 mm mount.
Upgrade paths
On LGA 775 the upgrade is the Pentium D 840 at 3.2 GHz in the same 130 W class, or the Intel Pentium D 820 at 2.8 GHz for 95 W operation. Beyond LGA 775 a move to a newer platform needs a new board and memory.
