HP Z800 Memory Upgrade Options

Hi!

I have a Z800 HP Workstation 64GB (8x8GB) with 4TB of storage capacity. The system is running in a dedicated SSD drive. The machine has 2x Intel Xeon E5675 Processor SLBYL 3.06GHz CPU, and now I am looking into expanding the RAM to 192GB (12 x 16GB PC10600R ECC Reg Modules); however,  I have checked with an IT local company, and they said that the Z800 power supply and the cooling system might not support this memory upgrade =/. Do you guys know if 12x16GB RAM modules would work in my Z800?

Thank you very much in advance
