Intel Core 2 Quad Q9550 2.83 GHz quad core Socket 775 CPU SLB8V 12M/1333, Yorkfield 95W

Here is a fast quad core Socket 775 CPU from Intel running at 2833 MHz, known as the Core 2 Quad Q9550.  It uses a 1332 MHz front side bus and has a generous 12MB L2 cache, and the "Yorkfield" core.

It uses 45 nanometer traces and draws 95 watts of power.  Further details are below (courtesy of cpu-world.com)

This CPU is not compatible with early socket 775 systems, so please check your system documentation for compatibility.  If you can't find a straight answer, ask me.  I would rather tell you no than waste our time with a return for compatibility reasons.

Also, note that you are purchasing only the CPU as pictured here (but not the exact one).  A CPU cooler (heatsink) is required but not included with this item.  (I do not have them).

Your CPU(s) will arrive working and packaged safely in antistatic bubblewrap.


Shipping via USPS first class mail is FREE within the U.S. and reasonable elsewhere.  Please let me know if you need a shipping method not listed here.  I can use UPS, FedEx. or US Postal service and will quote you the same postage cost I pay. The shipping methods listed here do not have any guaranteed delivery time, meaningful tracking, or postal insurance.

International Buyers – Please Note: Import duties, taxes, and charges are not included in the item price or shipping cost. These charges are the buyer's responsibility.  Please check with your country's customs office to determine what these additional costs will be prior to bidding or buying.

I welcome questions from interested bidders and offer a 30 day return privilege. I will consolidate shipping for winners of multiple items within 3 days.
