T5500 power boot up and shut down after few seconds when riser board connected

Hi there,

I bought second processor riser board for my T5500 workstation.

I put X5690 CPU and three 8G RAM on Riaser board and mother board both.

without riser board, computer working 100% Ok. but connecting riser board on mother board, it is booting up after 2 or 3 second, system power down.

please save me on this..

 

Many thanks

JW

  • Hi there, JW

    What is your current ram configuration (number of sticks and size) on your main board?

    • 이재웅 Do you have the 8GB sticks in slots 1,2, and 3 of the mainboard? If so then it's the correct configuration for that kind of setup. If that's it then have you tried reseating both the Ram and CPU on the riser? Failing that swapping the CPUs and see if the other x5690 will boot off the motherboard.

    • 이재웅 Also make sure the CPU/Riser power cable is firmly connected to the riser as well. From my own personal experience the T5500 reboots can happen if the Riser isn't seated correctly on the motherboard (sometimes pulling out and back in fixes this) also the power cable should be firmly in place. The other is the reseating of both RAM and CPU. The CPU swap was suggested because sometimes even a bad CPU or bent pins in the CPU socket will give off the same effect.

    • 이재웅 it’s plug and play.  Did you make sure to install matching step codes?  Do all of the memory modules match?

      Jbigticket23 Hi There, What is mean install matching step codes? All memory are working good though.

    • 이재웅 Your Intel CPU stepcodes must match.  What model cpu's do you have installed?

    • 이재웅 Hi JW,

      what @jbigticket23 was referring to was the 4 to 5 character code on each of the CPUs. Think of it as a serial number. It's usually under the model number. That code must match on both CPUs since Intel makes different variations of the cpu with the same model number.

    • 이재웅  Yes, the stepcode would be SLBVX on the X5690 CPU's.  Did you verify if all of the memory modules are matching?  You can't mix E dimms with R dimms.

  • You say it boots up for a few seconds then shuts down. Does that mean the POST screen shows then goes away?

     

    Does it boot without the riser board?

     

    Is the one cable that goes to the riser board in place?

     

    What are the lights on the front of the case (1, 2, 3, 4) doing?
