AMD A10-7850K socket FM2+ quad core CPU AD785KXBI44JA 3.7 GHz Kaveri Radeon R7:
AMD A10-7850K 3.7 GHz quad core Socket FM2+ desktop CPU AD785KXBI44JA, Kaveri, 95W
is a quad-core Socket FM2+ CPU/GPU from AMD running at 3700 MHz with a turbo frequency of 4100 MHz.
This one is known as the AMD A10-7850K. AMD's part number is AD785KXBI44HJ.
It uses the "Kaveri" core and 28 nanometer
traces. It includes 4MB of L2 cache, plus Radeon R7 graphics. It draws 95W of power This
CPU is compatible with most AMD socket FM2+ systems but the
buyer should check their system documentation for compatibility. (It will not fit in an older socket FM1 or FM2.) 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 exact CPU pictured here. It was one of the first production models, released in January 2014. 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 FM2+, 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. I will consolidate shipping for
winners of multiple items within 3 days.

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.
