1 Make sure DRAM is installed first in banks A6 and B6, 

followed by banks A5 and B5, etc. Do not install DRAM in 

banks A1 and B1 until all other banks are full.

2 Replace DRAM DIMMs one at a time to test DRAM. Replace 

any faulty DIMMs.

3 Replace logic board. Note: When you replace the logic board, 

be sure the LED cable is not interfering with the power 

actuator.
