Intel Xeon E7-4850 2.0 GHz 10-Core LGA 1567 130W SLC3V server processor
Ten-core server processor with 20 threads, 24 MB L3 cache and 130 W TDP for LGA 1567 platforms
- NameXeon E7-4850
- CPU Socket TypeLGA 1567
- Core NameWestmere EX
- # of Cores10-Core
- # of Threads20
- Operating Frequency2.0 GHz
- 10 cores and 20 threads handle heavy multi-threaded workloads

- 0 GHz base frequency delivers steady compute throughput
- 40 GT/s QPI links scale across four-socket systems
- 130 W TDP fits standard server cooling envelopes
Refurbished 10-core Xeon for multi-socket servers
This refurbished Intel Xeon E7-4850 delivers 10 cores and 20 threads at 2.0 GHz for LGA 1567 platforms. The 24 MB L3 cache and 6.40 GT/s QPI links suit scale-up workloads on compatible server boards. It is sold as a processor only without a cooling device. Buyers who need a new-in-box unit or a different socket should look elsewhere.
DDR3-1066 memory ceiling and QPI bandwidth limit
The integrated controller tops out at DDR3-1066, so faster modules will run at this speed. Four QPI links at 6.40 GT/s set the inter-socket bandwidth ceiling for multi-node configurations. The 130 W TDP defines the thermal envelope the system must dissipate. Builders targeting higher memory throughput or newer DDR generations cannot use this processor.
LGA 1567 installation requires server-grade cooler
Installation follows standard LGA 1567 procedure but demands a cooler rated for 130 W in a server chassis with adequate airflow. The processor will not function on boards that lack Westmere EX microcode support in the BIOS. Missing VRM phases or an undersized heatsink are the most common causes of thermal throttling or boot failure.

이 상품에 대한 질문
Which capacity should I choose for the L3 cache on this Xeon E7-4850?
This processor has a fixed 24MB L3 cache; there are no alternative cache sizes for the SLC3V model.
What does the 2.0 GHz operating frequency deliver in a live server?
Ten cores at 2.0 GHz with Hyper-Threading provide 20 threads for parallel workloads such as virtualisation and database tasks.
What does the 6.40 GT/s QPI link cap in practice?
The 6.40 GT/s QuickPath Interconnect sets the maximum data rate between this CPU and other sockets or the chipset in a multi-processor system.
