Tomorrow, I need to check if ASUS tech support says that it is OK to use the 64GB sticks to 512GB total RAM size. I need to also check my source for refurbished RAM sticks for 32GB and 64GB ECC RDIMM size.
Looks like you are right about AMD differentiating between HEDT and Server total RAM. Since receiving my MB and registering the serial number with ASUS, I was able to get personal answers about using 64GB RAM sticks to achieve 512GB in the 8 RAM slots. NO, use at own risk. As we all know it is best to use the largest RAM sticks available for future expansion. I was planning to use 4X64GB to achieve the 256GB maximum as indicated by Puget Systems and BOXX for their systems. I will now use the 8X32GB, since I have $5,000 invested in the CPU+MB and will not risk it.
