Refurbished Xeon X5675 processor upgrade

This refurbished HPE 633781-B21 is an Intel Xeon DP 5600 series processor upgrade with six cores running at 3.06 GHz. It targets IT teams maintaining compatible LGA-1366 servers who need a direct replacement or capacity increase. The 32 nm microarchitecture supports 64-bit processing and includes Intel Intelligent Power Technology.

Socket B LGA-1366 compatibility

The single specification that decides fit is the processor socket: this unit only works in systems with a Socket B LGA-1366 interface. Buyers must verify their motherboard uses this exact socket before purchase.

12 MB L3 cache and 6.40 GT/s interconnect

The 12 MB L3 cache and 6.40 GT/s QuickPath Interconnect provide headroom for multi-threaded server workloads such as virtualisation and database tasks. The six cores handle parallel jobs comfortably while the 1.50 MB L2 cache supports per-core throughput. Systems needing more than six cores or a newer socket generation will require a different platform.

Questions about this item

How does the 3.06 GHz clock speed translate to actual throughput in a live server?

The six cores run at 3.06 GHz with 12 MB L3 cache and 6.40 GT/s QuickPath links, letting multi-threaded workloads scale across the 32 nm hexa-core die.

What does the 6.40 GT/s QuickPath interconnect limit in practice?

The 6.40 GT/s link caps inter-socket bandwidth, so dual-processor configs share memory and I/O at that rate rather than a faster bus.

Will the Socket B LGA-1366 package drop into my existing board without extra hardware?

It fits any LGA-1366 (Socket B) server board; the green substrate matches the standard mechanical outline for that socket.
