🌟 Heritage Warehouse Stock:

This item is part of a large batch of legacy inventory inherited from an old computer storefront that closed its doors years ago. It has been safely stored in a climate-controlled, smoke-free backroom environment for decades.

📦 Item Condition:

Genuine Intel Pentium 4 2.40A GHz Retail Boxed Processor (sSpec: SL88F). This is a rare, pristine New Old Stock (NOS) vintage processor kit.

100% Unopened Factory Sealed Content: The clear plastic factory circular tamper seals on both the upper and lower flaps remain completely unbroken and fully intact (visible in image_YcngRp.png). The Prescott core CPU and matching original Intel factory heatsink/cooling fan remain completely untouched, zero-hour, and permanently sealed within the internal staging plastic matrix (as viewed through the verification cut-out windows in image__czu-T.png).

Please Note Box Cosmetic Flaws:

The original cardboard retail box has significant handwritten black felt marker identification text detailing the CPU specs across the front and side faces ("2.40A GHz 533/FSB Soc-478 1MB/CACHE"). The package features a green inventory tracking sticker reading "G39", an old red retail price tag, and displays light vintage shelf edge wear from long-term warehouse retention.

⚠️ RETRO COMPATIBILITY & OVERCLOCKING DISCLAIMER — PLEASE READ:

• This is a legacy 2004/2005 Socket 478 desktop processor. It WILL NOT fit or function in modern computer motherboards (such as modern Intel LGA 1700 or AMD platforms).

• Prescott Core Voltage Requirements: This specific 2.4A variant uses a 1MB L2 cache and 533 MHz FSB built on the 90nm Prescott architecture. It requires a compatible Socket 478 motherboard whose BIOS explicitly supports Prescott core voltage maps (1.4V Max). Older Socket 478 boards built strictly for Northwood cores may require a BIOS flash or may be incompatible.

• Buyer Technical Responsibility: Please consult your retro motherboard's manual and CPU support matrix to ensure it accommodates the Prescott 533 MHz FSB speed tier prior to purchasing. No technical configuration or hardware installation assistance is provided.

• Value Retention Note: Because this item is highly collectible to technology preservationists specifically due to its unopened status, returns cannot be accepted if the clear Intel factory round security seals are cut, broken, or peeled by the buyer.

• Fraud Prevention: To safeguard transactions against processor swapping, chip harvesting, or component return schemes, the factory production batch code (FPO/BATCH #: 7514A946T), the retail UPC barcode (735858166829), the EAN block (5032037004312), and the laser-etched serial matrix on the CPU face top view have been thoroughly logged, photographed, and recorded prior to shipping.
