Updating BIOS on Codex X

I have a Codex X desktop and I noticed that the ram speed was 2133mhz instead of the advertised 2400mhz. I suspected that this was due to xmp being disabled so I went into the BIOS to enable xmp. What I found was that the BIOS does not have an XMP option. So I figured I needed to update the BIOS to a later version of MSI 5. I used CPUZ to check the motherboard model number and it came back as "MS-B905" which is not a real motherboard. It seems to be named according to the desktop system rather than the actual motherboard. I did notice that it was a Z170 chipset which means faster RAM should be supported.
I went over to the support page for the Codex X and found that it does have a BIOS download page. However, it only has a single option, which is the one I already have (that does not have an XMP option!).
I went ahead and downloaded the BIOS, and there was a changelog [attachthumb=1]. 
On line 63, it says: " 01. Patch code for kingston issue : fix DRAM frequency to 2133MHz by PM request."
There are also references to XMP tweaks in the earlier logs, which I guess means that they took it out when they fixed the DRAM frequency to 2133 MHz.
I also noticed this line: " 01. First initial EB905IMS901 BIOS.(The Project is based on [MS-7998])",  and that changes for MS-7998 are included in the changelog.
MS-7998 corresponds to Z170A SLI PLUS which I suspect is the actual motherboard model in the system.

This leads me to believe that if I want to upgrade my ram speed, I'll either need to buy a new motherboard or try updating to the latest BIOS supported by Z170A SLI PLUS.

I also noticed in the BIOS that there was no option to do a flash. Instead, in the first few lines in [attachthumb=1], it says: !!!The end user want to update system BIOS to fix some bugs,  You can use flash tool AFUDOS.EXE(Version 5.07).
EX: c:\AFUDOS EB905IMS.9YY
And AFUDOS.exe is included in the bios folder. Does this mean I need to run c:\AFUDOS E7998IMS.130 ? (E7998IMS,.130 is a BIOS supported by the Z170A SLI PLUS).

I just find this entire scenario to be hilarious. I'm tempted to try doing this flash and then replacing the motherboard once it bricks itself.

Clearly that specification is not universal because it lists a 1080 instead of a 1070. Also, I did not say as specified, I said as advertised. Clearly in both of the above examples (the only sources I could find of this computer), the memory speed was advertised as 2400Mhz. I understand that this is not your fault or responsibility, but I don't see why pointing out the clearly non-universal specification is doing any good. All I want to do is buy some new ram with higher speeds and install it on my perfectly good motherboard. In the process, it seems like I need further guidance from you guys at MSI on how to go about installing a new BIOS supported by my motherboard. There are instructions in the BIOS folder supplied from the support website about using AFUDOS.exe but they are rather unclear. All I want is clarification on these instructions.

Hello. I'm having the same problem here. Any luck resolving it?
