What amd motherboards work with ddr3 ecc registered memory?

I have an amd phenom II 9950 125 watt am3 cpu, and
16GB of ddr3 1066 ecc registered 4x4G dimms

I am trying to find a motherboard that works with this memory.
I like the reliability of ecc, and I want ot use it.

Has anyone experience with this?

for example
4 x DIMM, Max. 16 GB, DDR3 1800 (O.C.)/1600 (O.C.)/1333/1066 ECC, Non-ECC, Un-buffered Memory

You need a server board, they are the only ones to support eec registered.

How on earth does one end up with $3000 of memory and no motherboard?

Do you mean like an opteron?
16GB of DDR3 1066 ecc-r was only $615.
16GB of non ecc was ~= $750.

The print was so small that I did not see the ecc until I got it.
Then I kind of liked the reliability, and decoded to try to find an appropriate motherboard rather than returning it.

The opteron looks good, especially shanghai, but doesn't the numa architecture mean that you can't address all of the memory from one CPU?

Are there any indications that some manufacturer plans to make an ecc-r motherboard for the Phenom II?

You can find motherboard which take ECC RAM which are not server boards but I do not think you can get buffered type motherboards what are not server type.

Since K8 core, ECC memory is already supported. Any motherboard for AMD K8 processors and up will work with out any problems when using ECC memory. Motherboard manufactures may not put in an option to tell the memory controller that you have ECC memory. Do not need to use an Opteron to get ECC memory. Your present processor supports ECC memory. Try running lshw or any program that looks up specs of the computer. For dual channel ECC memory, the programs should read 144 bit and 72 bit for single channel.

For your processor, you will need ECC unbuffered or ECC unregistered memory.
