AMD Phenom II X6 1055T 2.8 GHz Socket AM3 desktop CPU HDT55TFBK6DGR, 125W

Here is a 64-bit six-core Socket AM3 six-core 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 HDT55TFBK6DGR. AMD made two different Phenom II x6 1055T processors. This is the more common one: the 125W HDT55TFBK6DGR. The scarcer one draws only 95W and sells for more.

It uses the "Thuban" core and 45 nanometer traces. It includes 3MB 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. 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 many AMD socket AM3 systems (and some socket AM2+ desktop systems), but the buyer should check their system documentation for compatibility. Some socket AM3 systems can not handle a 125W CPU or 6 cores. Here is a link to a partial list of motherboards which support this CPU. 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 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.

International buyers: You are responsible for paying any additional customs duties or VAT your country may charge you.

Notes on AMD Phenom II X6 1055T (125W)
On socket AM2+/AM3 platforms in the minimum performance state the processor runs at 800 MHz core voltage and has TDP 55.4 Watt [1] - These characteristics were measured on a single CPU, and they can vary slightly for other processors with the same model number
