Socket 462 / Socket A

Socket 462 (also called Socket A) is a PGA socket designed for AMD K7 family of processors. This socket can be used with AMD Athlon and Duron processors ranging in speed from 600 MHz to 2200 MHz (3200+) and with bus frequences ranging from 100 MHz to 200 MHz (400 MHz DDR). For a full list of supported processors please see below.

Picture of Socket 462

Socket A has 462 pin holes (hence the name "Socket 462") with 11 pluged pin holes. Socket dimensions are 5.59 cm (5.24 cm without lever) x 6.55 cm or 2.2" (2.06" without lever) x 2.58", which is almost the same as Socket 7/Super Socket 7.

Supported processors

All processors in the table below will physically fit into the socket, but not all of them are supported by all motherboards. If you're upgrading an old computer system please make sure that the CPU is compatible with your motherboard. Please see "Upgrading socket A motherboards" section below for information on how to determine what microprocessors can be supported by your motherboard. #[Table]

Upgrading socket A motherboards

While you can fit many socket 462 processors into your motherboard, not all of them may be supported by the board. To determine what processors are supported you'll need to:

  • Determine manufacturer and model of your motherboard,
  • Search on manufacturer's website for the motherboard model.

To determine upgrade options for brand name computers (like Dell or HP) try to search for computer model on computer manufacturer website.

For upgrade information for ASUS, DFI, ECS, Gigabyte Technology, Jetway, MSI and PC Chips motherboards please check CPU-Upgrade motherboard database.

Processor Installation

For processor installation please look at your motherboard manual or download installation instructions from AMD website.

My Shuttle AN35N Ultra will handle an Athlon XP 3200+. If these are no longer made, do you know if my m/board will support a different AMD class?


Response: Athlon XPs are no longer produced. Your board may support Semprons, though the fastest Sempron 3000+ is as fast as XP 2700+

AMD Duron upgrade to AMD Athlon

2007-07-04 18:14:01
Posted by: Bradley Kirwan

Hi I am thinking about buying an AMD Athlon 1700+ Socket A/462 with a bus frequency of 133MHZ. I currently have an AMD Duron 900MHZ Socket A/462 with a bus frequency of 100MHZ. MY mobo has a jumper setting for bus frequency 100MHZ/133MHZ. If I bought the processor, installed it and then changed the jumper setting for Bus Frequency to 133MHZ, would my process be fully working?

AMD Duron upgrade to AMD Athlon

Response: Not necessary. Athlon XP has newer core which may not be supported by your board.

Hi. My question is about the Geode processors based on the T-bredB core and actual AthlonXPs. It is said that Geodes could run fanless up to 1000mhz which could not be said of my Athlon 1700+DLT3C JUIHB running 1000mhz at 1.13V<
is the GeodeNX a close relative of the 1700+ or were there any other major changes?

Do the low power consumption models Athlon SFF (and XP SFF) CPUs fit on socket-A motherboards????? The early press releases said they would have thier own special socket?????

Also what are the performance differences(if any) between the SFF CPUs and the standard Athlon CPUs????

some processsors that are not listed in your motherboard manual will work after upgrading the bios. so check your motherboard builder's site for bios upgrades and upgrade the bios before installing the new cpu.

I heard that amd athlon xp 3200+ is the fastest , but it runs on 2200 mhz , hmm my processor if i overclock it , it runs at 2.0ghz so what is the difference of those 200 mhz between the overcloked proc and the un-overclocked one. Please answer, and sorry for my bad english .

Response: The fastest socket A CPU is Athlon XP 3200+. Whether or not it is supported depends on your motherboard make and model.

Asrock K7S41GX and XP 3200+ Barton (Socket A)

2008-06-26 08:51:41
Posted by: Bryan

Thanks to some great advice from this website, I upgraded my Sempron 2500 to an Athlon XP 3200+ Barton core (AXDA3200DKV4D). However, in order to get the 3200+ to run at the correct speed I had to mildly overclock the mobo. In most of my research I found that Asrock socket A boards (with a few exceptions) only support a 333FSB, and not every BIOS supports the 3200+. I grabbed the latest BIOS from the manufacturer's website and it worked, although not at the right clock speed (1750 MHz). To get the 2.2 GHz you are supposed to get, you have to increase the system clock from 166 MHz to 200 MHz in order to get the required 400 FSB for the 3200+, and this is done in BIOS by setting the system frequency to manual. Bottom line: Yes you can run a 3200+ on most Asrock Socket A mobos with the right BIOS, and you must gently overclock. The performance increase in my case was quite evident, and I've had no issues regarding the O/C. I hope this helps some of you with older boards.

I have the mentioned ASUS motherboard. Manual says it supports upto 2.25 GHZ. What is the fastest processor that I can use. I do not mind to underclock the processor. It might even save some heat and the actual performance degradation might not be that big.

See article about this.
clockiing at 66% of maximum speed and lower voltage saved 66 % heat.

This way you can create a nice quiet media pc for a little money
