AMD Phenom II X6 1055T 2.8 GHz Socket AM3 desktop CPU HDT55TWFK6DGR, 95WHereis a six-core Socket AM3 CPU from AMD running at 2800 MHz with a turbo frequency of 3300 MHz when no more than 3 cores are in use. This one is known as a Phenom II X6 1055T. AMD's part number is HDT55TWFK6DGR. It draws 95W of power, so it will work in a Hewlett Packard system. (There is a more common, less expensive 1055T which draws only 125W, and does not work in many systems.)
It uses the "Thuban" core and 45 nanometer traces. It includes 3MB of L2 cache, plus 6MB of L3 cache. It includes its own memorycontroller for DDR2 or DDR3 SDRAM with a 2.0 GHz Hyper Transport Link. ThisCPU is compatible with many AMD socket AM3 systems (and some socket AM2+ desktop systems), but the buyer should check their system documentation for compatibility. Some systems have a BIOS which does not recognize a six-core CPU. Other systems can not handle a 125W CPU. In other cases A BIOS upgrade may be necessary to recognize this CPU properly. If youare not sure, ask me. I would rather tell you "no" than waste our timefor 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.
YourCPU 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 buyers and offer a 30 day return privilege. USPS First Class shipping is free within the U.S.
International buyers: You are responsible for paying any additional customs duties or VAT your country may charge you. Please do not ask me to falsify customs forms.

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.
