AMD Athlon 64 3400+ 2.4 GHz Socket 754 desktop CPU ADA3400AEP4AX 512KB L2, NewCastle 89W

Here is a Socket 754 single-core 64-bit CPU from AMD running at 2400 MHz. This one is known as an Athlon 64 3400+. AMD's part number is ADA3400AEP4AX. It uses the "NewCastle" core, and is the next-to-fastest regular desktop CPU AMD made for their socket 754. It is priced at about 40% of the cost of the 3700+ top socket 754 processor, with the same clock speed but half the cache memory.

It uses 130 nanometer traces, and draws 89 watts of power. It includes 512KB of L2 cache and its own memory controller for DDR SDRAM, with a "hyper-transport link" of up to 800 MHz.

This CPU is compatible with most AMD socket 754 desktop systems. In a few cases, a BIOS upgrade may be necessary to get this CPU recognized properly.

You will receive only a CPU as pictured here (but not the exact one). A heatsink and a fan are required but not included with this item. Your system will also need a good power supply.

Your CPU will arrive working with all pins straight and as pictured. I make sure it will drop into a socket 754, will insert the pins in a protective foam pad, and enclose it in a plastic clamshell before shipping it to you. If you need a free tube of thermal paste, just include a note with your payment.

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. Of the shipping methods listed here, only USPS Express Mail provides a real tracking number for international buyers.

Also, let me know if you need a shipping method not listed here. I can use any service from FedEx or US Postal Service and will quote you the same postage cost I pay

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.
