Wont Post get 9 beeps!

System doeIf there is one DIMM in the system the memory row/bank may be disabled when there is a memory failure. The system will not boot because it has no memory to use. If the DIMM is replaced with one of the exact same type and size, then the system will continue not to boot. BIOS cannot tell when a DIMM has been replaced with one of the exact type and size, therefore BIOS believes it is still the bad DIMM and will not use it.

Here are two possible workarounds:

1. After replacing the defective DIMM, continue to reboot the system until you hear the "no memory" post beep sequence (3-3-3) during POST (no video display). After three (3) incomplete boots, a "062 three consecutive boot failure. Using default CMOS configuration caches are off" error will occur. At this point BIOS will go back to the default settings and begin to use the new DIMM. However, if you have disabled the 3 boot fail count (this setting may not be available in all servers) in Setup, then BIOS will not turn the DIMM row/bank back on.
-=OR=

2. Remove the DIMM. Power on the system until the "no memory" post beep sequence (3-3-3) is heard. The memory row/bank will now be marked as being empty. Power off the system and put a good DIMM back into the system. The memory DIMM row/bank is re-enabled and the system boots normally.

NOTE: If more than one DIMM (or more than one DIMM set) is installed in the server and one memory (or one memory set) row/bank is disabled due to a memory failure then, the user must go into setup and re-enable the row/bank after replacing the bad DIMM.

Below are IBM BIOS Beep codes that can occur. However, because of the wide variety of models shipping with this BIOS, the beep codes may vary. Beep Code Description Document No Beeps No Power, Loose Card, or Short. CH000312 1 Short Beep Normal POST, computer is ok. No problem 2 Short Beep POST error, review screen for error code. See screen Continuous Beep No Power, Loose Card, or Short. CH000607 Repeating Short Beep No Power, Loose Card, or Short. CH000607 One Long and one Short Beep Motherboard issue. CH000607 One Long and Two Short Beeps Video (Mono/CGA Display Circuitry) issue. CH000607 One Long and Three Short Beeps. Video (EGA) Display Circuitry. CH000607 Three Long Beeps Keyboard / Keyboard card error. CH000304 One Beep, Blank or Incorrect Display Video Display Circuitry. CH000607

Standard Original IBM POST Error Codes 1 short beep Normal POST - system is ok 2 short beeps POST Error - error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem 1 long, 1 short beep System board problem 1 long, 2 short beeps Display adapter problem (MDA, CGA) 1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 3 long beeps 3270 keyboard card

The IBM POST code states that after the 2 beeps the screen displays the error.
In the case you have a faulty fan and it needs to be replaced.

The IBM Netfinity 5600 is a complicated beast for sure. You really need to get a copy of the Netfinity Manual from IBM (not on the web site fyi.). It's as big as the machine unfortunately. In section 3, p.124 it lists 3-3-3 beep code as "No memory has been detected in the system" solution is "Reseat mem modules or install mem modules. If prob persists get machine serviced." On the previous page, 3 short beeps (only) on POST indicate "system mem error. combo only occurs when video bios cannot display error msg. replace the failing mem module." You might also want to check the light-path diagnostics inside the machine. A little light will be illuminated right beside the bad DIMM.

The processor fan should have failed. check it out.

Hi,

Have you tried http://www-304.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=SERV-GUIDE&brandind=5000008?

It may have what you're looking for.

Dear NickB,

In my experience working with many servers, Non-ECC memory will not work on a machine that requires ECC memory. It is possible in some servers to disable the ECC mode in the system BIOS to allow non-ECC memory to work, but you will often end up with performence problems later on.
Hope this information helps, let me know if I can be of any further assistance.

i am using a compaq vrm for my 3500 m20:
the number is:
320266-01
spare:329267-001

this one works!!

re-install the old bios. evidently the new flash bios is not compatible with your machine.
