Two questions... Why does the motherboard website say this: - Quad Channel DDR4 Memory Technology - 4 x DDR4 SO-DIMM Slots - Supports DDR4 4000+(OC)* / 3866(OC) / 3800(OC) / 3733(OC) / 3600(OC) / 3200(OC) / 2933(OC) / 2800(OC) / 2666 / 2400 / 2133 non-ECC, un-buffered memory - Max. capacity of system memory: 128GB** - Supports Intel® Extreme Memory Profile (XMP) 2.0 *The maximum memory frequency supported may vary by processor type. **Due to the operating system limitation, the actual memory size may be less than 4GB for the reservation for system usage under Windows® 32-bit OS. For Windows® 64-bit OS with 64-bit CPU, there is no such limitation. https://www.asrock.com/mb/Intel/X299E-ITXac/index.asp#Specification My processor states that 128GB is possible via the Intel site... https://ark.intel.com/content/www/us/en/ark/products/189127/intel-core-i9-9920x-x-series-processor-19-25m-cache-up-to-4-50-ghz.html Long story short my question is why can't I add four 32GB DDR4 2666Mhz RAM in the available slots? I am thinking this is based from a bios manipulation on Corsair's side. When will there be a update for the owners to fully utilize our system's potential.... Or why not give us the ability to use ASRock's bios directly? Thank you for the insight, Alan P.s. I am now the owner of 4 Corsair Vengeance SODIMM 32GB (1x32GB) DDR4 2666 C18 1.2V for Intel 9th & 10th Gen Systems, Black : https://www.amazon.com/gp/product/B0815H1RB8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Should I return these?
