Memory Errors

When a No_Memory_Beep_Code is issued by the system, check the following:
1. Make sure that the DIMM modules are properly and fully installed.
2. Check if different speeds of DIMMs have been installed. It is strongly recom-
mended to use the same RAM speed for all DIMMs in the system.
3. Make sure you are using the correct type of DDR3 Registered ECC or
Unbuffered ECC/Non ECC 1333 MHz/1066 MHz/800 MHz SDRAM (recom-
mended by the manufacturer.)
4. Check for bad DIMM modules or slots by swapping a single module between
all memory slots and check the results.
5. Make sure that all memory modules are fully seated in their slots. Make sure
to follow the instructions given in Section 2-4 in Chapter 2.
6. Check the position of the 115V/230V switch on the power supply.
7. Please follow the instructions given in the DIMM Population Tables listed on
Pages 2-7 and 2-8 to install your memory modules.
