✅ Confirmed Compatibility
Please note that the following list is not exhaustive. Compatibility depends on your system's specific configuration. It's essential to verify compatibility with your system or enclosure manufacturer prior to installation.
✔️ IBM System x: x3850 (Type 8864), x3950 (Type 8878), x3950 E (Type 8879)
✔️ Dell PowerEdge: 6850 (verify BIOS level and system board revision before installation)
☑️ Key Features
☑️ High-frequency dual-core Xeon MP processor for legacy 4-way capable server platforms
☑️ Large 16MB L3 cache for enterprise workloads on older server architectures
☑️ Multiple interchangeable Intel and IBM/Lenovo part numbers for easier sourcing
☑️ Socket 604 package for compatible Xeon 7100-series server systems
☑️ Good replacement option for maintaining older IBM System x and compatible Dell enterprise servers
⚙️ Fit Notes
- This CPU is not a universal Socket 604 part. Socket match alone is not enough — the server board/chipset/VRM and BIOS must specifically support the Xeon 7100N series.
- For Dell PowerEdge 6850 systems, confirm the server is on a BIOS version that supports Xeon 7100 dual-core L3 CPUs and verify the system board revision before ordering.
- HP ProLiant G4 platforms (such as DL580 G4 / ML570 G4) commonly use the 71x0M 800MHz FSB versions (for example, 7140M) rather than this 7140N 667MHz FSB model. Do not substitute unless your exact HP documentation confirms support.
- This is a high-power server CPU (150W TDP). Proper heatsink fitment and airflow are required. Use fresh thermal compound during installation such as Shin-Etsu G751.
- In multi-CPU systems, match CPU family and platform support across all installed processors for best stability.
