HP Xeon X5675 Processor Upgrade

This refurbished HP 638871-B21 processor upgrade adds a six-core Intel Xeon X5675 running at 3.06 GHz to compatible Hewlett-Packard servers. It targets administrators who need additional compute threads for virtualisation or database workloads on existing LGA-1366 platforms.

Socket and Power Verification

Confirm the host board uses Socket B LGA-1366 and can supply 1.4 V DC with a thermal envelope of 95 W. The system BIOS must support the 5600 series stepping, and the chassis airflow must handle a maximum case temperature of 81.3 °C.

Build and Mounting Implications

The green substrate measures 1.7 inches by 1.8 inches and fits the standard LGA-1366 retention mechanism without adapters. A 12 MB L3 cache and 6.40 GT/s QuickPath Interconnect are integrated, so no extra cabling or daughter cards are required for operation.

Questions about this item

Does the HP 638871-B21 Xeon X5675 processor arrive with a heatsink or thermal paste, or must they be purchased separately?

This processor upgrade ships as the CPU only; a compatible Socket B LGA-1366 heatsink and thermal compound must be sourced separately for installation in a Hewlett-Packard SL390s G7 ProLiant server.

Should I choose this X5675 3.06 GHz hexa-core model or a different 5600-series processor for my SL390s G7?

Select the X5675 when you need six cores at 3.06 GHz with a 95 W thermal design power; other 5600-series models vary in core count, clock speed and TDP, so match those figures to your workload and cooling capacity.

What does the 3.06 GHz clock speed mean for real-world performance once the X5675 is installed in a server?

Each of the six cores runs at 3.06 GHz, delivering 12 threads via hyper-threading and 12 MB L3 cache, so multi-threaded applications scale across all cores while the 6.40 GT/s QuickPath Interconnect keeps data moving between the processor and the system.
