内存检测工具输出的数据，还在查DDR4的原因

尽量描述具体些

搞不懂啊，就发现出现问题的设备有个共性低八位没问题，高八位数据随机时间出错

dhr8369

CPU core operating speed of up to 1.2 GHz
High-speed 8/16-bit DDR3/3L/DDR4 DRAM memory controller
The SDRAM interface clock—up to 800 MHz for DDR3/DDR4 respectively
DDR选用的是三星的DDR4-2666，1333MHz fCK for 2666Mb/sec/pin

DDR高八位偶有读写错误是哪的问题？有遇到解决的吗？
