8-core Xeon for ThinkSystem SR650

The Lenovo 7XG7A05575 is an Intel Xeon Silver 4110 processor with 8 cores and 16 threads running at 2.1 GHz. It delivers 11 MB of L3 cache and a 85 W thermal design power. The part is validated for the ThinkSystem SR650 server platform and fits the Socket 3647 interface. It suits administrators who need balanced multi-threaded performance for virtualisation or database workloads.

Upgrade path from lower-core Silver SKUs

Moving from a 4-core or 6-core Silver processor to this 8-core model adds two to four additional cores and doubles the thread count to 16. The 2.1 GHz base frequency and 11 MB L3 cache improve throughput for parallel workloads such as container hosts or mid-range SQL instances. The jump is worthwhile when current CPU utilisation regularly saturates available threads and the SR650 chassis has adequate cooling headroom for the 85 W TDP.

Socket 3647 installation in SR650

Installation follows the standard LGA 3647 procedure: open the carrier, align the processor notches, close the carrier and torque the heat-sink retention nuts to the specified pattern. The SR650 service manual calls for a compatible heatsink rated for at least 85 W and correct thermal-paste application. Common issues include bent socket pins during carrier closure, mismatched heatsink mounting hardware, and BIOS versions that do not recognise the Silver 4110 stepping without an update.

Questions about this item

Will this CPU fit the Socket 3647 motherboard in my ThinkSystem SR650?

Yes, it uses the Socket 3647 interface and is validated for the Lenovo ThinkSystem SR650 server platform.

What installation step is often missed when fitting this 85 W processor?

Applying thermal paste evenly and torquing the heatsink to the specified pressure so the 77°C thermal limit is not exceeded.

How often should the thermal interface be refreshed on this 14 nm Xeon?

Reapply quality thermal compound every two to three years or whenever the cooler is removed to maintain the 85 W heat transfer.
