前言:
BIOS的版本-CPUIMC(内存控制器)-内存颗粒/PCB-主板供电及内存布线-时序(CPU-SOC-内存)电压设置都会影响内存超频的能力在这些前提之前,也可以根据在系统内查看的数值记录(Ryzen Timing checker和DRAM-Calculator-for-Ryzen)或拍照下来,然后在进入BIOS进行适当的设置!

Processor:CPU类型
Memory Type :内存颗粒
Memory Rank: 内存Rank单双面
Frequency(MT/s):内存频率
DIMM Modules:内存数量
点击R-XMP→Calculate SAFE:即可看到推荐值,右边两项为快捷和极限推荐值,小白的话点击SAFE即可!
超频配置:
BIOS版本:E7B89AMS.160
CPU:Ryzen5 2600 6C12T
散热:九州风神玄冰400
主板:AMD B450M MORTAR
内存:HOF 3600 8GX2
电源:航嘉Jumper 450bv
首先重启一直按键盘上的Delete键(有些主板进入BIOS按键不同,详情可查看主板说明书或者百度主板型号进入BIOS方法,一般都是Delete或者F2键进入BIOS)
选择高级内存配置,进行内存时序修改:(以下名称为B-die的均为Samsung B-die)
DRAM Frequency 就是内存频率的选择 我们这里选择为3400

简单的超频主要进行主时序修改即可,这个此帖开头有帖子教程


FCLK:Infinity Fabric总线用于ccd/ccx与io die和io die连接内存之间的总线,在Ryzen里能效达到1:1会使内存性能得到最大的发挥,在intel叫北桥频率
内存频率=FCLK*2,例:FCLK频率为1800Mhz则内存频率为3600Mhz,FCLK频率越高说明CPU的IMC越强,Zen2-Zen3设置FCLK可以直接1800起步
想深层次了解FCLK的可以找一下网上的解析
CR:默认1T,如果上高频不稳定设置为2T
tCL:此项时序中最重要的一项,数值越低性能越强,平时常见的16-18-18-35的16则为tCL。
tRCD:一般设置为tCL+(1-2),若不稳定可提高
tRP:一般设置与tRCD同数值,若不稳定可提高
tRAS:该值一般设定为tCL+tRCD+(1-2),若不稳定可提高
tRC:该值一般设定为tRAS+tRP(1-6),若不稳定可提高
tRRDS-tRRDL:一般值项为4-6 6-8 8-10,根据情况适当提高或缩减
tWTRS:该项和tWTRL最好是一起设置,一般是设置为4-12,也可以适当提高到6-14
tFAW:该值越低会使系统负载的时候性能更强,一般不小于tRRD的4倍,一般设置值为16-34
tWR:该值一般默认即可,会影响系统行为,当然也是数值越低越好,一般设置为16-34
tRFC:此项非常影响内存性能的一项,tRFC数值越小性能越强,该值一般设定为tRC+(2-6),但是受频率提高的影响,该值必须设定在一个合理的范围。一般三星B-die颗粒设置为280-350
Ryzen会存在1/2/4的情况,一般tRFC2是tRFC1的75%,tRFC4是tRFC1的45%,如果拿捏不定,可以直接修改1/2/4单独一项
tRDRDSCL:该值默认在Ryzen上一般是4-6,也是影响内存性能的一项,该值越低性能越强,一般设置为3,追求性能设置为2(但有可能过不了测试或开不了机)
tWRWRSCL:该值默认在Ryzen上一般是4-6,也是影响内存性能的一项,该值越低性能越强,一般设置为3,追求性能设置为2(但有可能过不了测试或开不了机)
tRTP:与tWR类似,定义rank内存读取发出到tRP之前的间隔时间,如果bank增大,该值也要放宽,Ryzen一般设置为8-14
tCKE:一般在Ryzen上直接设置为1,值项一般(1-8)若不稳定可适当提高
(tRDRD SD-DD)-(tWRWR-SD-DD):可以直接通过主板的Auto值来缩减,或者直接使用Auto值
tWRWR-SC:默认1即可
tRDWR:Auto即可
Gear Down mode:该值根据MSI林大解析效能等于2.5T最好设置为Disabled,顺便说一句,内存tCL如果想设置为奇数(单数)此项也必须Diasbled
Power Down Enable:此项应为内存节能选项,选择关闭
TSME:网上说关闭此项能减小内存延迟,在Ryzen的说明里这项功能是安全内存加密,能不能减少延迟本人也没证实过,有兴趣的可以试试
DRAM SOC电压:适当提高该电压可提高内存超频稳定性,一般为1-1.2V。
以上值为个人理解,其他小时序或者不想太麻烦,可以直接通过DRAM-Calculator-for-Ryzen这项软件的推荐时序进行适当的压缩或放宽
超完频后,进入系统打开Memtest测试,能过200%-300%无错误就表示超频成功!


由于之前忘记截图了,就放一个最先超频的跑测试吧,性能小参差不了多少

超频前:装完系统直接进系统跑的测试

超频后:CPU OC@4.1G 内存 3400 CL14


以上就是AMD内存超频的方法和推荐了,有任何疑问可以在本帖留言
