ASRock Z890 Taichi OCF (OC Formula) is geared toward record-setting overclocking, and is from the same category as the GIGABYTE AORUS Tachyon, and ASUS ROG Maximus Apex. Besides an overpowered CPU VRM and a boatload of features relevant to professional overclockers, this board has a 1-DIMM per channel memory configuration that provides the best memory overclocking headroom. There are quite a few enthusiasts who just want the pesky memory out of the way and focus on CPU overclocking. For this exact niche, ASRock developed a variant of the Z890 Taichi OCF with a DDR5 CAMM2 slot.
