I have an error 19F visible in bios of my SR1500. Processor and chipset stepping configuration is unsupported.....
Platform ID: S5000XAL.
BIOS Version: S5000.86b.15.00.0101 of September 11th, 2010.
Server 1 :
Processor 1 and 2 Intel QuadCore L5320@1.86GHz - > Stepping : 07 - > CPUID Register : 000006F7.
Server 2 :
Processor 1 and 2 Intel QuadCore E5335@2.00GHz -> Stepping : 07 -> CPUID Register : 000006F7.
I read this post : http://communities.intel.com/thread/26057 http://communities.intel.com/thread/26057
It mean that I have to downgrader my BIOS ? Has anybody already solved this type of problem ?
Thank you for avnace.
What's the PBA# of your board? Check http://www.intel.com/support/motherboards/server/sb/CS-023585.htm Server Products — Important information on support of Intel� Xeon� Processor 5300. If it's lower than -801, there is no solution but to change the board or CPU, since it's a hardware limitation.
My PBA# is : D46952.702.
I realized a test on one of my server.
I made a downgrade of BIOS (via the following page: www.intel.com/support/motherboards/server/sb/CS-023585.htm) for the version S5000XAL.
Resul : no error message in BIOS, both processors are recognized. My server W2K8-R2 knows eight processors, as well as Sandra Sysoft.
Does it seem to you correct to think that the downgrade was benecial ?
Not really... Just the old BIOS is not "aware" of the limitation. The voltage regulators on the old board revision is not designed to support Xeon 5300 series. It may cause unexpected behavior, like system unstable, halt, reboot, even hardware failure.
