Thank you for choosing EcoSave, where we prioritize sustainability by offering refurbished and used CPUs. By opting to upgrade with our products instead of buying new ones, you are making an environmentally friendly choice that helps reduce electronic waste.

• Product Condition: The CPU you are ordering, designated as OEM, may be new or refurbished. The condition can range from new to like-new, pulled, or pre-owned, depending on the age of the CPU and how long it has been out of production.
• Availability: For older CPUs that are no longer in production, pre-owned or pulled parts are often the only available options, ensuring you have access to necessary upgrades.
• Quality Assurance: All OEM CPUs are thoroughly tested before shipping and come with a 21-day warranty for replacement. Please note, there are no cancellations or returns accepted for these parts.
• Compatibility Check: Please verify your system requirements carefully before ordering CPUs to ensure compatibility.
• Dual-CPU Servers: If you are using the CPU in a dual-CPU server or machine, it is essential to match the SL code of the new CPU with your existing CPU. Contact us if you need assistance with matching SL codes.
• SL Codes: All Intel CPUs are designated by a Step code or SL code, a 5-digit alphanumeric code found on the CPU itself. To run dual CPUs in one machine, their SL codes must match.
• Brand Specific Requirements: If you have a branded computer (e.g., HP, Dell, IBM), you must provide us with a HeatSink part number. Otherwise, we will ship a generic heatsink if you order one from us.

We appreciate your decision to support sustainable computing by opting for our EcoSave initiative of refurbished and used CPUs. Your choice helps extend the useful life of computer hardware and minimizes environmental impact. Review Feb 2026
