Xeon X5675 processor upgrade

This refurbished HP 637345-B21 processor upgrade adds a hexa-core Xeon X5675 running at 3.06 GHz to compatible ProLiant servers. It targets administrators who need additional compute capacity in existing Socket B LGA-1366 platforms. The 95 W thermal design power fits within the original cooling envelope of supported systems. Buyers who want more storage or a different socket type should look elsewhere.

Socket B LGA-1366 and QuickPath limits

The processor installs only in Socket B LGA-1366 motherboards, restricting use to servers designed for the 5600 series. Its 6.40 GT/s QuickPath Interconnect sets the maximum link speed between sockets, so multi-processor scaling cannot exceed that bandwidth. The 32 nm process and 12 MB L3 cache define the performance ceiling for this generation. Systems requiring higher interconnect speeds or newer socket standards are not compatible.

Green PCB, 1.7" × 1.8" package

The green substrate measures 1.7 inches wide by 1.8 inches deep, matching the standard LGA-1366 form factor for direct drop-in installation. A 95 W TDP and 81.3 °C thermal specification mean the existing heatsink and airflow must handle that load without modification. Compatibility is confirmed for the Hewlett-Packard DL160 G6 ProLiant server; other chassis may need verification before purchase.

Questions about this item

Is this the right processor upgrade for my HP ProLiant DL160 G6 server?

This Xeon X5675 is listed as compatible with the Hewlett-Packard DL160 G6 ProLiant Server. It uses the Socket B LGA-1366 interface and has a 95 W thermal design power.

What real-world performance does the 3.06 GHz clock speed deliver?

The six cores run at 3.06 GHz with 12 MB L3 cache and a 6.40 GT/s QuickPath Interconnect. The 32 nm process and automatic power regulation balance throughput with the 95 W TDP.

Does the LGA-1366 socket limit memory speed or bandwidth?

The processor fits Socket B LGA-1366 and provides a 6.40 GT/s QuickPath Interconnect. Memory speed and maximum capacity are determined by the DL160 G6 system board, not by the CPU alone.
