    Does the WX58BP actually support ECC?!

    Uncle_Steve

      Despite Intel's literature claiming support for ECC, I'm starting to get skeptical. Does anyone out there have an example of a WX58BP actually using ECC? If I boot in Linux and run dmidecode, here's what I get on a WX58P:

       

      sudo dmidecode -t 16
      # dmidecode 2.9
      SMBIOS 2.5 present.

       

       

      Handle 0x0014, DMI type 16, 15 bytes
      Physical Memory Array
          Location: System Board Or Motherboard
          Use: System Memory
          Error Correction Type: None
          Maximum Capacity: 8 GB
          Error Information Handle: Not Provided
          Number Of Devices: 4

       

      Note the "error correction type" of "none." If I do the same thing on a Dell server:

       

      dmidecode 2.9
      SMBIOS 2.5 present.

       

      Handle 0x1000, DMI type 16, 15 bytes
      Physical Memory Array
          Location: System Board Or Motherboard
          Use: System Memory
          Error Correction Type: Multi-bit ECC
          Maximum Capacity: 8 GB
          Error Information Handle: Not Provided
          Number Of Devices: 4

       

      I'm more than willing to accept "operator error", but the silence on this subject is deafening.

       

      I could have saved 15% and just bought an i7-based system.  :-(

          Yes it does; but you need a processor that also supports ECC,  remember that the motherboard no longer has the memory controller this  is now on the processor(this is true for all i3/i5/i7 and W3500/W3600  processors).

          You don't say what processor you have; if you have a  standard i7 then you won't get ECC but if you put a W3540 for example(  http://ark.intel.com/Product.aspx?spec=SLBEX ) then you will.

            Apparently there's no Linux driver yet, but I would have thought Win 7 would have support, but for the life of me, I can't find any indication of it. The system has a Xeon W3520:
