    SUN BLADE 1500(red) and OBP 4.30.3

    807557
      Hello.
      I recently updated my OBP in sb1500 from 4.9.5 to 4.30.3 (#140686-01)
      I did not expect a hardware incompatibility. My mistake - did not read the documentation.
      Now try to match the correct memory.

      With the original DIMMs # 370-6202-01 (PC2100R 512MB ECC CL2.5 - M312L6420ETS-CB0) I get the message:
      Configuring system memory & CPU(s)
      +.+
      ERROR: CPU0 DIMM 0  SPD reports DIMM cycle time is less than 133 MHz
      System configuration failed, powering off
      Syst.

      So I bought a 3th part faster memory of a similar type (PC3200R 512MB CL3 ECC - M312L6420EG0-CCC) but I get similar message:
      Configuring system memory & CPU(s)
      +.+
      ERROR: CPU0 DIMM 0 SPD reports DIMM has unsupported CAS latency value
      System configuration failed, powering off
      Syst.

      As i read in datasheets: in new memory supported CAS latency is 2,5 and 3.
      In original it was 2 and 2,5.


      So PC2700 is required and CL2 or CL2.5?
      So what I have to pay attention to when selecting memory for this computer?
      Do I require SPD 1.0, or it can be SPD 0.0?

      Maybe someone has a working sb1500 with OBP, and can write memory model? I would be grateful.

      Regards.
