What the Xeon E3-1230 is
Intel Xeon E3-1230 is a quad core Sandy Bridge server processor that Intel released in April 2011 for single socket servers. It runs at 3.2 GHz base with turbo to 3.6 GHz and includes Hyper-Threading, so 4 cores give 8 threads. Cache is 8 MB Intel Smart Cache. Power is 80 W on a 32 nm process.
Eight threads at 80 W serve virtual guests well. Entry server racks use it for cost sensitive duty. Fixed firmware keeps behavior predictable.
There is no integrated graphics on this die, so server boards provide BMC video for management. Memory is DDR3 with ECC in two channels.
Socket and motherboard compatibility
The Xeon E3-1230 fits LGA 1155 in FCLGA1155 form. Single socket server boards with C202, C204 and C206 chipsets carry Sandy Bridge E3 parts. The board BIOS must list the exact E3-1230 string.
Desktop boards may boot the chip electrically, but ECC and BMC management need a server board. Use a server board for the intended role.
Memory, PCIe and cooling
Memory support is DDR3-1066 and 1333, two channels, up to 32 GB with ECC on server boards. ECC catches single bit errors in always on service. Capacity follows the board design.
PCI Express is 20 lanes from the CPU at PCIe 2.0 for network and storage. Server boards spend lanes on reliable I/O.
Cooling is an 80 W server heatsink with directed airflow. The CPU cooler compatibility by socket guide notes server cooling stays chassis specific.
Upgrade paths
On LGA 1155 the E3-1230 can move to the E3-1240 for higher clocks on the same server board. Memory and storage carry over where the board lists both strings. A same socket graphics-less quad reference without threading is Intel Xeon E3-1220.
A platform move to a current server socket needs a new board and DDR4 memory. Keep the E3-1230 node for entry duty.
Frequently asked questions
What socket does the Intel Xeon E3-1230 use?
It uses LGA 1155 in single socket server boards.
Does the Xeon E3-1230 have Hyper-Threading?
Yes. Four cores give 8 threads.
Does the Xeon E3-1230 have integrated graphics?
No. It is a server part without integrated graphics. Boards use BMC video.
