Hi and Dear Msi, you are doing a splendid job for all these years keep up the good works for the Msi Owner and Msi Community Member.

Kingston 2x16gb KF560C40BBK2-32 Assemble In Taiwan (Purchase in the year 2022) ram slot populate at 3&4
Kingston 2x16gb KF560C40BBK2-32 Assemble In China (Purchase recently Manufacture year 2023) ram slot popuate at 1&2
Thermaltake View 71 Casing ( with all side mount and mirror mount dismantle body remain only)

Am currently having ram that cannot operate at 6000mhz with all four slot occupy, xmp profile 1 which is a 6000mhz setting will not boot properly until it goes back to bios menu. A profiles 2 which operate at 5600mhz with no issue at all and last is the profile 3 is giving me a 4800mhz (Default Ram Frequency). Normal with no Xmp enable surprisingly at a 4000mhz (weird, suppose to be at 4800mhz default setting but show 4000mhz only) . No problem when using two ram slot profile 1 can reach 6000mhz anytime but with four slot populate it cannot reach 6000mhz no boot at all boot back into bios menu only.

Please do not advise me not to use four slot ram which cannot reach 6000mhz use two instead. It is perfectly normal user will have two ram with their first build and latter add another two ram usage. My knowledge is achieving all four slot to 6000mhz is to alter the ram vdd voltage 1.25 volt to 1.35 volt from bios setting but i do not want to do that. Any help will be very much appreciated thank you in advance.

P/S:- Hopefully a future bios updates from MSI with (profile 1) will fix this ram issue (finger cross).

Your Truely

Proud MSI Owner.
