Enthusiast was able to make 1 TB of RAM work in the motherboard on the X299 chipset

Officially, this board only supports 256 GB
ASRock announced that well-known overclocking enthusiast Nick Shih was able to install 1 TB of memory in the ASRock X299 Taichi CLX motherboard designed for workstations. Officially, this board supports up to 256 GB of memory.

To achieve this, Shi used an Intel Core i9-7900X processor and eight SK Hynix LRDIMMs of 128 GB each. The source notes that the X299 chipset does not support EEC memory and LRDIMM. It is not yet clear what tricks Shi resorted to in order to make the above memory work on the ASRock X299 Taichi CLX.

SK Hynix already offers 256 GB LRDIMMs, but they operate at an effective frequency of only 2666 MHz. As can be seen in the screenshots, those used by Shih worked at a frequency of 2933 MHz with timings CL21-21-21-47 and an operating voltage of 1.20 V. They carry the catalog number HMABAGL7MBR4N-WM, but are not yet in the manufacturer’s assortment. Even more interesting, Shi managed to raise the effective frequency to 3471.8 MHz with CL20-24-24-56 timings.
