（1）DDR5规范的主频是3200-8400MHZ，但是厂商的产品都是4800MHZ起步
（2）容量增大
（3）DDR5内存全线支持ECC
（4）海力士的DDR5年内量产，具体时间未透露

SK Hynix has today posted an update on their blog about the upcoming DDR5 memory,
which they have developed in co-respondence with JEDEC's progression of the standard.
They have noted a few key things, among which some of the most interesting are features
like the maximum speed of 8400 MHz. The DDR5 standard is very flexible, allowing
manufacturers to release their chips with frequencies ranging anywhere from 3200-8400 MHz.
While the lowest speed is 3200 MHz, manufacturers are starting with 4800 MHz chips
and building their way up from there. The minimum density of a single DDR5 die is 8 Gb,
while the maximum is 64 Gb, quadrupling the maximum capacity of DDR4 dies.

Perhaps one of the biggest changes besides capacity and speed improvements is the
addition of Error-Correcting Code (ECC) support for memory. This feature is now not
exclusive to special dies, like with DDR4, but rather is built inside every die. The DDR5
memory chips use 32 banks, split into 8 bank groups, which is designed to provide as
much bandwidth as possible. Burst Lenght is doubled to 16, compared to 8 of DDR4,
so memory access availability is better. Operating Voltage is decreased to 1.1 V, from
the previous 1.2 V of DDR4, resulting in an overall decrease of 20% of power consumption.
The mass production of SK-Hynix's DDR5 chips will start this year, however, timing is
unknown.

说实话,为什么我原来在服务器BIOS里看到ECC校正的错误有一些,但是使用普通内存的普通电话也没有发现出太大问题那? 是操作系统或软件在哪里校正的内存错误吗?

普通内存怎么可能没有错误
你看看系统log各种错误，有硬件有软件的，只是你觉察不到。
