Here is a 64-bit Socket AM3 quad-core CPU from AMD running at 3200 MHz. This one is known as the Phenom II X4 955. AMD's part number is HDZ945FBK4DGM. "Black Edition" means that it has an unlocked multiplier, for flexibility in overclocking.
It uses the "Deneb" core and 45 nanometer traces. It includes 2MB of L2 cache, plus 6MB of L3 cache. It includes its own memory controller for DDR2 or DDR3 SDRAM with a 2.0 GHz Hyper Transport Link. It draws 125W of power (more than some other Phenom II X4 955s). If you have a socket AM3 motherboard, it also supports DDR3 memory, and works with DDR2 memory in a compatible Socket AM2+ motherboard.
This CPU is compatible with most AMD socket AM3 systems (and many socket AM2+ desktop systems), but the buyer should check their system documentation for compatibility. Here is a link to a partial list of motherboards which support this CPU. A BIOS upgrade may be necessary. Some motherboards can not handle a 125W CPU. If you are not sure, ask me. I would rather tell you "no" than waste our time for a return over compatibility.
You will receive only the CPU as pictured here (but not the exact one). A heatsink and a fan are required but not included with this item. If you need a small tube of thermal paste, just let me know at the time of payment.
Your CPU will arrive working with all pins straight and as pictured. I have made sure it will drop into a socket AM3, and have inserted the pins in a protective foam pad and enclosed it in a plastic clamshell for shipping.
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.
Please let me know within three days of purchase if you can't use PayPal or prefer not to use that payment method. However, I accept credit card payments only through PayPal.
Shipping to any address in the U.S.
with a zip code is FREE via USPS first class mail. I ship only to the
address PayPal gives me. I offer inexpensive USPS first class
international shipping everywhere else, if you don't mind the delay and
lack of meaningful tracking.
Also, let me know if you need a
shipping method not listed here or if you need a quote for consolidated
shipping. I can use any service from UPS or US Postal Service and will
quote you the same postage cost I pay.
International buyers: You are responsible for
paying any additional customs duties or VAT your country may charge you.

The processor you are purchasing is a delicate part which two different people have inspected. Each of them was able to insert this CPU into an appropriate socket, but we probably have more experience than you. Please do not be offended if we include some installation instructions.
Here's the technique we use to straighten pins. It requires sunlight, a magnifier, a utility blade and perhaps a safety pin. First, hold the CPU at about a 10 degree angle to the socket and see if you can insert the outer row of pins for only one edge. If you feel any resistance, do not push down. The resistance point helps you locate the troublesome area. Use the utility blade along the sides of the pins to push up any pin that isn't upright. (If the pin is almost flattened you can raise up the end by inserting a safety pin underneath it and lifting the back of the safety pin). Then use the side of the utility blade to make the CPU pin stand up perpendicular to the base, in a line the other pins in that row. Try to avoid any pressure near the base of the pin (which is where they break off). Repeat this process for each of the 4 edges. Then decrease the angle so the inner rows of pins go in the holes and on all 4 sides. Again, try to locate any resistance points for each side and repeat as necessary. Eventually you should be able to use the CPU. Do not spend too much time on this.
