AMD Phenom II X4 940 3.0 GHz Socket AM2+ desktop CPU HDZ940XCJ4DGI, 125W

Here is a Socket AM2+ quad-core CPU from AMD running at 3000 MHz. This one is known as the Phenom II X4 940 Black Edition.. It was sold with an unlocked multiplier, for flexibility in overclocking..

It uses the "Dragon" core and 45 nanometer traces. It draws 125W of power. It includes 1MB of L2 cache, plus 6MB of L3 cache. It includes its own memory controller for DDR2 SDRAM with a 1.8 GHz Hyper Transport Link.   Although it will physically fit in a socket AM3, IT WILL NOT WORK WITH DDR3 MEMORY.

This CPU is compatible with most AMD socket AM2+ systems (and a few socket AM2 desktop systems), but the buyer should check their system documentation for compatibility.   Some systems will not handle a 125W CPU, It will not work in a Hewlett Packard system. A BIOS upgrade may be necessary. 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 present. 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 buyers and offer a 30 day return privilege.

Notes on AMD Phenom II X4 B95
Business class processor

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.
