Single 32GB Support

titlebg

Maximum memory capacity on Z490 motherboard is 128GB. After Intel update the memory reference code, single slot support up to 32GB. Therefore with populated 2 DIMM per channel on both channel, total memory capacity is 128GB, which was only available on High End Desktop (HEDT) platform. For users who always run out of memory capacity, there is more bandwidth now. Easier and smoother for those memory intensive application such as rendering and video editing.
