What socket does the Intel W-2123 use, and which workstation motherboards are compatible?
The W-2123 uses the LGA 2066 socket, compatible with Intel C422 chipset workstation motherboards — platforms like the Asus Pro WS X299 SAGE II, Gigabyte X299 DESIGNARE EX, and similar W-series Xeon validated boards. It is not compatible with consumer LGA 2066 X299 boards unless those boards explicitly list Xeon W support in their compatibility documentation.
What is the ECC memory support status of the W-2123?
Yes — the Xeon W-2123 supports ECC (Error-Correcting Code) memory, which is the primary architectural distinction between this workstation CPU and consumer Core i-series on LGA 2066. ECC detects and corrects single-bit memory errors in real time, making it the appropriate platform for financial modeling, scientific computing, CAD, and other applications where data integrity is non-negotiable.
How many PCIe lanes does the W-2123 provide, and what does that mean for expansion?
The Xeon W-2123 provides 44 PCIe 3.0 lanes directly from the CPU. This is substantially more than consumer desktop CPUs — 44 lanes supports simultaneous use of multiple PCIe x16 GPUs, high-speed NVMe RAID arrays, and Thunderbolt cards without lane contention, which is why the W-series platform targets professional workstation builders.
What is the TDP of the W-2123, and what cooling is required?
The W-2123 has a 120W TDP — meaningfully higher than consumer desktop i5/i7 chips. Standard consumer coolers designed for 65–95W TDP CPUs are insufficient for sustained workloads at this TDP. A workstation-grade tower cooler or a 240mm+ AIO rated for 150W+ TDP is the appropriate thermal solution for this processor.
What does "renewed" mean for this CPU, and what should I verify before using it?
The SR3LJ W-2123 is listed as professionally inspected and tested to perform like new. For a CPU, renewed typically means the processor has been electrically tested for correct operation across all cores and cache. Before deploying in a production environment, run a stress test suite (Prime95, Cinebench multi-core) to confirm stability under sustained full-load operation, which can surface latent issues not caught in basic functional testing.
