alienware 18 DIMM access controller for RAM damaged, worth changing ?

[Omadon]

Hello everyone,

 

first of all I am very happy to have found this forum.

 

I have been a hard-core & die-hard user of the AW18 for 12 years now and simply refuse to buy another laptop for daily use.

 

One of my 4 models has developed the following problem:

 

The DIMM RAM access controller 1 seems to be faulty.

 

I have switched all kind of RAM to all positions and found that whenever any RAM is placed in controller 1, the laptop does not POST and I get four beeps.

 

I have tried all combinations, so the access controller seems to be faulty.

There is no visible damage and I have tried cleaning it, but that didn't change anything.

 

As the maximum RAM for my processor running Windows 7 Ultimate seems to be capped at 32 GB, I wanted to ask if it is possible, instead of changing or repairing the motherboard to use the following combination on the 4 controllers:

 

controller 0: 16 GB

controller 1: leave empty

controller 2:  8 GB

controller 3:  8 GB

 

Any suggestions would be greatly appreciated.

 

Regards,
