What the Xeon E5-2689 is
Intel Xeon E5-2689 is an eight core Sandy Bridge-EP server processor that shipped in March 2012 for dual socket servers sold through system makers. It runs at 2.6 GHz base with turbo to 3.6 GHz, with 20 MB cache and Hyper-Threading for 16 threads. Power is rated at 115 W on a 32 nm process. No public ARK v1 page exists for this OEM oriented SKU, so the TechPowerUp database entry plus the HMC catalog entry carry the clocks, cache, power and socket facts used here.
No integrated graphics are present. Memory spans DDR3-800 to 1600 over four channels with ECC for up to 384 GB, and the chip gives 40 PCIe 3.0 lanes plus two 8.0 GT/s QPI links. High base with a tall turbo suits mixed virtualization and database hosts.
Boards pair it with registered DIMMs in 1U and 2U chassis from the system maker that qualified it. The maker CPU support list is the only compatibility reference for OEM SKUs without an ARK page. The Socket vs chipset: what decides whether a CPU works guide explains why that list outranks the chipset name.
Socket and motherboard compatibility
The Xeon E5-2689 fits LGA 2011 in FCLGA2011 form. Dual socket Romley boards with the C600 series controller carry it where the maker lists the SKU. Because no ARK page exists, the system maker board and BIOS revision decide compatibility, not a generic chipset table.
At 115 W full size server heatsinks apply. The CPU cooler compatibility by socket guide covers server heatsink classes.
Memory, PCIe and cooling
Memory support is DDR3 at 800, 1066, 1333 or 1600 MT/s, four channels, with ECC and registered DIMMs for up to 384 GB. Full population feeds sixteen threads.
PCI Express is 40 lanes of PCIe 3.0 per socket. Two QPI links at 8.0 GT/s join pairs. NUMA placement matters on dual boards.
Cooling is vendor qualified for 115 W. No retail mount exists.
Upgrade paths
Within LGA 2011 the Xeon E5-2689 can move to standard Sandy Bridge-EP or Ivy Bridge-EP eight core parts on the same board, where the maker list allows. Memory and storage carry over. A close standard comparison is Intel Xeon E5-2690 with higher clocks at higher power.
A platform move means a DDR4 generation. Keep the node for mixed host duty.
Frequently asked questions
What socket does the Intel Xeon E5-2689 use?
It uses LGA 2011. The system maker board and BIOS decide compatibility.
Why is there no ARK page for the Xeon E5-2689?
It is an OEM oriented SKU documented in the TechPowerUp database and catalog listings rather than a retail ARK page.
What memory does the Xeon E5-2689 use?
DDR3 at 800, 1066, 1333 or 1600 MT/s, four channels, with ECC and registered DIMMs.
Is the Xeon E5-2689 for dual socket boards?
Yes. The 2600 numbering allows two sockets.
