IBM 00FK644 Xeon E5-2640 v3 2.60 GHz 8-core processor upgrade

SKU CH-4S6Z-KK0D7 MPN 00FK644

Eight-core Xeon processor upgrade for the x3650 M5 server running at 2.60 GHz with 20 MB L3 cache

  • Electrical Outlet Plug TypeProcessor Upgrade
  • Eight cores handle parallel workloads with 2.60 GHz base frequency
  • Turbo frequency reaches 3.40 GHz for burst performance
  • 20 MB L3 cache reduces memory latency for large datasets
  • 90 W thermal design power limits cooling requirements in dense racks
  • LGA 2011-v3 socket fits IBM x3650 M5 server platforms

Refurbished Xeon E5-2640 v3 server processor

This is a refurbished Lenovo Xeon E5-2640 v3 processor upgrade operating at 2.60 GHz with eight cores. It uses the LGA 2011-v3 socket and a 22 nm process. The unit draws 90 W thermal design power at 1.3 V DC. It is intended for compatible IBM server maintenance or expansion.

LGA 2011-v3 platform constraints

The processor fits only LGA 2011-v3 sockets and communicates through QuickPath Interconnect at 8 GT/s plus Direct Media Interface at 5 GT/s. Maximum operating temperature is 74.3 °C. The package measures 2.1 by 1.8 inches. These electrical and physical limits define the platform boundary.

Verify IBM x3650 M5 compatibility before ordering

Confirm the target system is an IBM x3650 M5 and that the BIOS revision supports the E5-2600 v3 series. Ensure the server cooling solution can dissipate 90 W within the 74.3 °C thermal specification. Buyers needing a different socket or a newer processor generation cannot use this part.
