2nd processor wont boot hp

Hello,
I have HP Z600 Workstation running well with a single Xeon Processor 5600 (socket 0). (http://tinyurl.com/myHPz600) When I add another Xeon Processor 5600 (socket 1) to make it a dual Processor Workstation it does not boot or get to the BIOS Screen.

When I remove the processor after testing it feels warm so I know power is getting to it.

Things I have tried:

Tested the 2nd Processor in socket 0 (works with only 1 processor installed)

Tested the heatsink/fan in socket 0 (works)

Upgraded the Bios Reset the CMOS booting in Linux & windows 7

I have not touched the Jumpers.
I have not increased the 650 watts Power supply

I have noticed a very small defect on 2 pins on the processor socket. I have not attempted the bend them back!

Any help on this would great - I'm pulling my hair out!

  1. A picture would work wonders in this regard - for us to see the "defect" on the processor socket. If it is bent, you can totally destroy your CPU, motherboard and everything.
  2. Yeah it really depends on what this small defect is. get a pic uploaded if possible
  3. Hey guys, Wow thanks for the fast reply.

    I am away from my workstation now but I can upload a close up of the CPU socket in about 4 hours.

    Thanks for your help.
  4. Part of the service lol. Ok matey
  5. I assume the CPUs are identical? Not vital, but you may not always get a 5520 chipset booting with two different models.

    Another thing that you didn't mention was if you are booting with memory installed for both CPUs.
  6. Hi,

    Yes, both are 5620 Xeon 2.44.

    Each processor sockets has 3 dedicated ram slots - thinking it could be bad ram, I have tried booting with only 1 ram stick - then 1 stick in each (made by the same manufacturer).
  7. I forgot to say, the Heatsinks are different in each sockets.

    Socket 0 - Arctic Cooling Freezer 7 Pro (tested and working)
    Socket 1 - OME HP heatsink and fan (tested and working)

    I guess it would'nt need to draw more Watts from the power supply if the fan is different?
  8. Hi, I hope the images are clear enough. I also added the full shot of the motherboard just incase.

    Thanks for your help

  9. A quick update -
    I changed the ram over to another brand - Changed my quadro 600 card back to a default Quadro nvs 290. - started up the machine - held down f8 - the pc went to bios this time - selected Hardrive - said the hardware had changed and booted to windows! Cool - But before I had chance to checkout how many cores were running in task manager it said found new drivers and asked for a restart. Thinking it was just a ram issue I just clicked restart!

    On restart the fans started on full speed and no bois this time! Back to square one! The Harddrive sounds like its running and loading the os but screen is blank!!!
  10. :hello: Toxxyc and dhicks19 I have uploaded the images.

    I'm stil running on 1 processor! Does anyone know where I can go from here?
  11. A new motherboard is all I can think of. General rule is when something is bent/broken, it's not worth replacing. I don't know about server components though, take the motherboard to a reputable repair shop and let them take a look. If they can do something as simple as bend it back, you'll be lucky enough to keep it.
  12. Thanks very much for your help. I will take it to my local repair shop, or does anyone know a good place in Sussex, England?
  13. No idea. I'm in South Africa... :D
  14. Hello, did you resolve this issue ? I am having the same problem.

    I am having tha exact same problem. But I can confirm that there is actually nothing (physically) wrong with my second
    CPU socket. This is why:

    I have two E5530 xeon cpus and the Z600 works fine, but I also have two X5660 and if I insert more than one
    of them the system stops booting. Resulting only the case fans blowing with maximum speed.

    Both X5660 processors work fine if installed alone.

    I have latest bios installed.
  16. Any update with this issue. Same issue here
  17. Hallo zusammen
    Ihr habt alle das gleiche Problem. mit den HP Z600 und Z800
    HP haben die Maschinen in zwei Baureihen.
    1. ist für die Xeon 55xx Serie Rev 001 > geht nur mit Xeon 5502 bis 5570
    2. ist für die Xeon 55xx Serie Rev 002 > geht nur mit einer Xeon CPU 5603 bis 5675 bei der zweiten bootet die Maschinen nicht. Der Intel Chipsatz 5500 vom Mainboard ist zu alt
    3. ist für die 56xx Serie ab Rev 003 (zb: 460840-003 Intel Chipsatz 5520 )Größer AJ Laufen beide Xeon 56xx Serien 5603 bis 5675 Bios ab 2010-03-15
    Dei der Z800 ist das gleiche Problem.
    Also wenn ihr das nächste Mal ein Schnäppchen bei eBay seht passt auf was ihr da kauft.

    Hi
    You all have the same problem. with the HP Z600 and Z800
    HP have the machines in two series.
    The first is for the Xeon 55xx series Rev 001> is only with Xeon 5502-5570
    The second is for the Xeon 55xx series Rev 002> is only possible with a Xeon CPU 5603 to 5675 in the second machine will not boot. The Intel chipset 5500 from the mainboard is too old
    The third is for the 56xx series from Rev 003 (eg: 460840-003 Intel Chipset 5520) Greater AJ Xeon 56xx series running both 5603-5675 bios from 2010-03-15
    Dei the Z800 is the same problem.
    So if you see a bargain on eBay the next time fits what you are buying.

  18. The answer is located in this PDF document (click to view)

    This is a direct quote from hp.com support in the above PDF document:

    Support for Xeon 5600 Series processors requires the C2 revision of the Intel 5520 chipset. Two methods
    are available to determine if a specific Z600 system has the C2 revision of the chipset. 1. Use the BIOS
    setup menu to access the "Boot Block Date" from the "System Information Menu". All B3-based systems
    will have a "1/30/09" date and C2-based systems will have a "01/07/10" date. 2. HP Performance Advisor
    SW can be used to determine the PCA ID, which is reported by Performance Advisor under "System
    Configuration" and "Baseboard ID". All B3-based systems will have the ID "0AE8h" and all C2-based systems will have the ID "0B54h".


    So this is why only one x5670 6 core processor is allowed.
