Matched Pair Intel Xeon Gold 6140 2.3GHz 18-Core Server CPU (SR3AX) - Skylake-SP

Matched Pair Intel Xeon Gold 6140 Processors

Premium matched pair of Intel Xeon Gold 6140 18-core server processors. Sourced from datacenter liquidation, tested functional. Same stepping/week for dual-socket BIOS compatibility. Ideal for HPE DL380 Gen10, Dell PowerEdge R740, Supermicro X11 dual-socket boards, and compatible LGA3647 platforms.

Pair Specifications

• Cores/Threads: 36 cores / 72 threads total (18C/36T per CPU)
• Clock Speed: 2.3 GHz base, 3.7 GHz turbo (Intel Turbo Boost 2.0)
• L3 Cache: 24.75 MB per CPU (49.5 MB total)
• TDP: 140W per CPU (280W combined for dual-socket)
• Socket: LGA3647
• Architecture: Intel Skylake-SP (Xeon Scalable 1st Gen)
• Memory Support: Up to 768 GB per socket (DDR4-2400/2666)
• Uncore Features: Intel UPI (10.4 GT/s), QPI support, PCI-E 3.0 x48

Condition & Testing

• Used datacenter pull — fully functional, normal cosmetic wear
• Individual thermal load testing completed on both units
• Matched stepping verification — same CPUID for stable dual-socket operation
• Ready to ship — no packaging or accessories included

Why Matched Pairs Matter

Dual-socket server boards (especially older BIOS revisions) are sensitive to processor stepping mismatches. Mismatched steppings can cause boot failures, BIOS errors, or performance throttling. This pair is verified identical stepping from the same manufacturing week, eliminating compatibility risk.

Compatibility

• HPE ProLiant DL380 Gen10, DL360 Gen10
• Dell PowerEdge R740, R640 (2-socket configurations)
• Supermicro 2U/4U X11 dual-socket systems
• Any LGA3647 dual-socket server board (Xeon Scalable 1st Gen)

Important Notes

• Requires adequate server-grade CPU coolers (2x for dual socket = 280W dissipation)
• DDR4 ECC memory recommended for datacenter/server use
• Firmware updates may be required on older board BIOS for full stability
