DDR5 Memory Slot Tester Wide Compatibility DDR5 Memory Tester for Memory5321\n\n1. DDR5 doubles the memory read speed to 6.4 Gbps, while also greatly increasing memory capacity. DDR5 bandwidth for DDR4 twice, module transfer rate can reach 4.8 Gbps , faster than DDR4 existing new module 3.2 Gbps 50%, transfer rate is expected to reach 6.4 GbpSo\n2. DDR5 device internal operating voltage of 1.1V, more power-efficient than DDR4's 1.2V. DDR5 form factor to maintain the same number of 288 pins as DDR4, but the definition is different, not compatible with DDR4 slot.\n3. DDR5 tester all support for , for all DDR5 interface motherboard, with light-emitting diodes to indicate the data line, address line open and short circuit, used to repair not boot, not display, not read the memory and other motherboard failure, is a tool to repair the computer motherboard.\n4.
