    Help Identifying Processor (steppings)

    armstrhu

      Hello,

      I have a Dell server that can handle Dual CPU's. Currently there is one CPU there and would like to add the second.  The CPU currently in there is a dual core Intel Xeon 5150, with stepping 6.  I see that there ar 3 differen't types of 5150's :

      • SL9RU (B2)
      • SLABM (B2)
      • SLAGA (G0)
      • Is there anyway for me it identify which one I have, without having to remove the heatsink? Also, do I need to match the steppings or would any 5150 work? If I dont HAVE to, is it more efficient if I did? Thanks for you help

          Several, but it would help to know what OS your running?

           

          In Windows, I would use CPUZ http://www.cpuid.com/softwares/cpu-z.html

          Or the  Intel® Processor Identification Utility if you need a bootable version.

          ( not as easy to read the stepping revision and appears to hang my system for about a minute when I start it so have patience.)

          This will get you the stepping (B0 or G0) but not to the specifiv S-spec, but if they are G0, there is only one.

          If you want to match them and they are B0, you may need to pull the heat sinks.

            So I used the intel processor identifier. this is what comes out

             

            SPEC Code

            Ordering Code Media Stepping Socket CPU ID VT-x
            SLAGABX805565150ABOXG0LGA77106FBtrue
            SLAGABX805565150PBOXG0LGA77106FBtrue
            SLAGAHH80556KJ0674MTRAYG0LGA77106FBtrue
            SL9RUBX805565150ABOXB2LGA77106F6true
            SL9RUBX805565150PBOXB2LGA77106F6true
            SL9RUHH80556KJ0674MTRAYB2LGA77106F6true
            SLABMBX805565150ABOXB2LGA77106F6true
            SLABMBX805565150PBOXB2LGA77106F6true
            SLABMHH80556KJ0674MTRAYB2LGA77106F6true

             

            I have Xeon 5150 Family 6, Model 15, Stepping 6. From what I can tell this converts to CPU ID 06F6.  There are 6 options, all with stepping B2 but different SPEC codes.  I am not sure if you know, but am I correct in assuming the BOX are just retail versions and TRAY is an OEM, so that there is no real difference between those? In that case, it would be down to SL9RU ann SLABM. I guess it would be nice if I could match the processors exactly, but I do not want to have to pull the heatsink if that is the only way to find out the SPEC code. The main thing I am concerned with is if it would work or not. If there is a chance it might not work, if you know any other way to get the SPEC code other than pulling the heat sink that would be great. Thanks

              sorry i forgot, I am running linux (Ubuntu 10.10)

                yeaks Linux!!!!  (I am a hardware guy and have always preferred point & Click)

                 

                The System Information tool has a Linux version for Red Hat and Suse. I don't know if it would work on Ubuntu http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=19656&lang=eng&wapkw=(Intel+System+Information+Retrieval+Utility)

                 

                But it sounds like your sure you have the B2 so I don't know that you need it.

                 

                The S-Spec number (SL9RU or SLABM) Identifies the physical processor. The Ordering code is specific to how I is packaged.

                 

                You would need to check DELL's support sited on mixing S-spec processors in your specific server.

                Mixing speeds or steppings is usually not recommended, but I think you would be just fine as long as both are 5150's and the B2 stepping.

                  On Linux it is very easy.  Just type "cat /proc/cpuinfo" and it will give information on all CPUs/cores.
