I have the problem in using DDR3-1333 memory in 2022TC-BIBQRF (H8DCT-IBQF). The problem is when I am using 16GB memory sticks, it never goes for maximum DIMM size support which said in website to support 128GB as maximum. Reason?
C32 platform can support maximum 128GB memory capacity. But, recent 8GB are all coming with Q-RANK DIMM module. Refer to AMD memory support matrix, those Q-RANK memory will have to insert on DIMM B. The maximum GB per channel is limited at 32GB. If you have 2 DIMMs with 16GB inserted on DIMMB, it will give you 32GB for each CPU. The maximum of this mainboard is upto 64GB support at this moment.
