For sale is my ASRock X399 Taichi motherboard. It will boot up and run Windows, but there are problems with the motherboard. DDR_C1 andDDR_C2 will not detect any RAM installedthose slots. The RAM can be detected in certain situations (They show up in CPU-Z, even if the motherboard disables them), but the RAM capacity from those slots will not be available in Windows and show as "None" in BIOS. The middle M.2 slot between PCIE2 and PCIE4 will not detect any M.2 devices.BIOS has been updated to the latest available as of August 2026.Comes with pre-installed M.2 screws, a set of generic Wi-Fi antennas, and an aftermarket I/O shield. Does not come with retail box or any other accessories not pictured.
This motherboard was shipped as part of a prebuilt computer at some point, so any damage or symptoms may be related to damage during shipping. It was also in storage for a long period of time, so the CMOS battery may be dead if there is a battery still installed, and there may be dust, scratches, dents, bent or broken pins, or other physical damage not explicitly described. You will receive the exact motherboard that is pictured, so make sure to check all of the photos closely for actual physical condition.Your purchase comes with everything pictured. You are only buying what is pictured, and nothing else. If a cable or something else is not pictured, it is not included!SHIPPING AND PURCHASE TERMSIdo combined shipping discounts! Multiple quantity listings already have automatic shipping discounts included, but multiple items from different listings do not.
