The linchpin of ADATA’s XPG Z1 DDR4 modules is its Thermal Conductive Technology, which improves heat dissipation to boost performance. ADATA has certainly put TCT to good use, as its XPG Z1 kits are already available at speeds up to 2,800MHz. ADATA also plans on releasing a 3,200MHz kit in the near future. The XPG Z1 lineup is already an imposing collection, considering the DDR4 standard is still in its infancy. ADATA sent us a 16GB 2,400MHz quad-channel kit (model AX4U2400W4G16-QRZ) to put through the wringer.
