IBM Xeon X5690 six-core server processor

The IBM 81Y6725 delivers an Intel Xeon X5690 running at 3.46 GHz with six cores and twelve threads. A 12 MB L3 cache and 6.4 GT/s QPI link support multi-socket scalability. The processor targets DDR3-1333 memory through an integrated controller and carries a 130 W thermal design power.

Upgrade path from earlier Westmere or Nehalem CPUs

Replacing a lower-clocked quad-core or six-core Xeon with this 3.46 GHz part raises single-thread speed and keeps the same socket and memory infrastructure. The jump is worthwhile when workloads need higher per-core frequency and the platform already supports 130 W TDP processors with DDR3-1333 memory.

Suits legacy server refreshes needing maximum

This bare processor fits administrators extending the life of qualified IBM server platforms that accept the X5690. It is not for builders who need a heatsink in the box, for systems that require a different socket or memory generation, or for any non-server desktop or workstation board.

Questions about this item

What socket and power rating does the Xeon X5690 81Y6725 need for mounting?

The processor has a 130 W thermal design power and the listing states a cooling device is not included, so a server-grade heatsink rated for at least 130 W must be sourced separately.

What installation step is often missed with this bare processor?

Because the 81Y6725 ships without a heatsink or fan, the critical step is applying thermal paste and mounting a compatible cooler before powering on the server.

What ongoing maintenance does the X5690 6-core CPU require?

The 12 MB L3 cache and 6 cores run at 3.46 GHz with a 130 W TDP, so regular dust removal from the heatsink and periodic thermal-paste replacement keep temperatures stable.
