SHUTTLE SH55J, Corsair XMS3 16GB

I am trying to upgrade memory amount in a SHUTTLE SH55JSCG.

Shuttle specs say this is a 16GB motherboard.

It has been running Corsair XMS3 4GB DRAM successfully.

The BIOS is the most current available.

 

I tried installing Corsair XMS3 16GB CMX16GX3M2A1600C11.

The system stalls during POST. Where the POST status screen normally writes what it finds as dram slot by slot, it now just paints all of those lines solid white and the process halts. There is no error message of any kind.

 

The memory is being installed in the correct slots and is seating properly.

I have tried setting DRAM frequency manual to 1333, no joy.

What configuration do I need to achieve 16GB?

Thank you.

That's a 2x8gb kit. Specs says 16gb (4x4gb). Very likely the board does not support 8gb modules. You'd want a 4x4gb kit for 16gb. If it did support 8gb modules it would support 32gb max.

I will see about exchanging what I purchased and rack this up to a rookie mistake. Thank you.

I exchanged the memory for four pieces of 4GB. I installed Corsair CM18GX3M2A 1600C9 in all four slots. The result is identical to what I had earlier, the computer tries to boot and locks up on POST.

 

I pulled out two pieces, leaving 8GB on the motherboard. Same no joy result. I put the original two pieces of 2GB back in and the computer boots. Do you have any followup thoughts?

 

Right now it is looking like the solution will be to throw this box away and build a brand new one. Many, many man-hours. And no doubt there will be problems galore and unknown to make a perfect duplicate. Thank you for your insights.

Can u go into bios will old modules and set voltage and timings of the new ram then shutdown and install 2 sticks of the new ram and see if that works. May takes some trial and error.
