Intel第九代系列的桌面CPU
2019年第二季後會更新為R0 Stepping(步進)
依照Intel的說法
Stepping 13是修正Spectre V2,Meltdown V4,MSBDS,
MLPDS和MDSUM增加了硬體弱點對策修正
拿到R0步進的新CPU
主機板BIOS一定要更新到最新支援R0步進的版本
比如像Core i7-9700這一顆CPU
一上市就只有R0步進的版本
如果主機板仍是舊版BIOS,雖然可以正常開機
但Windows作業系統可能無法安裝
或是已經裝好Windows系統,使用時系統可能會崩潰

Intel第九代系列CPU
2019年第二季後會更新為R0步進
現有的i9-9900K、i9-9900KF、i7-9700K、
i5-9600K、i5-9600KF...等會從P0步進升級到R0步進
i5-9400F、i5-9400...等會從U0/P0步進升級到R0步進
目前列出有13個型號
https://i.imgur.com/4Y0F9UA.jpg
現在市面上零售版除了i7-9700全都是R0步進的版本外
i7-9700K、i9-9900K..也有看到有R0步進版本出現
https://i.imgur.com/PMU4QGY.jpg
左方SRG15是R0步進,右方SRELT是舊的P0步進
(i9-9900K的P0步進是SRELS,i5-9600K的P0步進是SRELU)
其他CPU型號新舊步進序號可參考:
http://bbsah.com/thread-72237.htm
基本上
R0新步進版本的序號
就看盒子上或CPU頂蓋上序號SRG__就對了
大家之後購買列表上型號的CPU
就可能拿到R0步進新版本
記得主機板要更新到最新版本BIOS
才能正常使用

好像」還是沒修掉。目前聽到的是最快要comet lake
才會修掉的ht的bug
