MSI B85M-G43 with OEM BIOS

[Derchris1]

Hey there,
I have bought this board as an used board (Rev. 1.2) with BIOS version E7823IMT V3.14B8. I guess its an OEM board/BIOS. Does anyone know if there is a newer E7823IMT BIOS version available and where to get it?
Or is it possible to crossflash it with the newest E7823IMS.390 BIOS version by renaming it to E7823IMT.390? Or should it be updated via DOS and AFUDE238.exe or via MSI_UEFI_FlashTool?

Another question: There is this option "BIOS Boot function (Enable/Disable)" in MFlash menu where you can select a bios file on usb drive to boot from. Can anyone tell me what does that exactly mean? Is it possible to boot a newer BIOS version for testing from USB without updating the existing one on the board (and maybe crash it)?

Thanks in advance for any help .

not by renaming

Or should it be updated via DOS and AFUDE238.exe or via MSI_UEFI_FlashTool?

Different one >>Forum USB flasher<<

Something like this, but doesn't worked good.

Some more information from my side:
From my old Dell T20 (mainboard failure) I want to reuse the xeon E3-1225 v3 togehter with a 4 GB RAM module and additional 2x8 GB RAM modules from G.SKILL. Therefore I bought that MSI mainboard. Together with an old PSU (bequiet dark power P7 550 W) I built everything into the MSI board, either only the 4 GB module or the 2x8 GB modules.
As you can see from the pictures in both cases the BIOS recognizes the components (at least so I think).

What somehow bothers me is the build date of this "special" BIOS version E7823IMT from 2019. Whereas the latest MSI BIOS version 3.9 for this board is from 2015.

With both RAM configurations the system runs stable while in BIOS @ 40°C. I also run memtest86 in DOS mode with both configurations for 20 min and 50 min with no errors and stability problems.
The only problem now is, when I boot Win 10 from the ssd sometimes the system reboots while loading, sometimes it is able to load into win 10 desktop and then after some seconds/maybe 1-2 minutes it also reboots without any error messages or so. It is like you switch power off and on. In both RAM configurations it is the case.
I don't have a clue where such a behaviour can result from.

Sounds like a PSU issue.

Don't mix RAM modules, will always end up being a problem.

ogether with an old PSU (bequiet dark power P7 550 W) I built everything into the MSI board

Dark Power P7 is an ancient PSU, almost 20 years old, with three years warranty! There is no way it's still in the best shape. Electrolytic capacitors inside PSUs slowly deteriorate with age, plus back then, the technology wasn't that advanced. Even the most high-end PSU you'd replace after 10-15 years.

I would say, grab some money and get a new PSU, this one has done its duty and can go to the retirement home (electronics recycling). See my Guide: How to find a good PSU. At the very least, you should test with a known good (borrowed) PSU of decent quality, preferably still within its warranty period.

You are right, points on your side. With my second PSU Straight Power 11 the system works fine and stable. I will get a new one.

But really weird thing is:
I did a cross check and put the P7 back into my really old system where it was used ever since. An old GA-78LMT with an Athlon II X2, 8 GB RAM and an old Crucial 128 GB SSD with Win 10. With that setup Win 10 is booting stable and also runs stable when loaded. But when switching to the Samsung SSD and trying to install Win 10 the same problem occurs and the system randomly powers off.
I even did an 1:1 cloning of the Crucial SSD to the Samsung SSD with Clonezilla --> loading Win 10 from Crucial SSD works stable, loading the same Win 10 from Samsung SSD instable

Yeah, thought so, 20 years is too old. Maybe you can still use some of today's high-end PSUs in 20 years, as the technology is better than 20 years ago, and they even have PSUs with 10-12 years warranty now. But almost all of the PSUs that are already almost 20 years old now can cause weird effects, instability, file corruption and sudden shutdowns by now.

It's also not that uncommon for them to appear ok with one configuration, but cause severe problems with another configuration (although seeing it depend on a specific SSD is a first for me). This is because one configuration might slightly push things over the edge, or is more sensitive to whatever is already quite bad in the PSU's output (like excessive voltage ripple, because the secondary-side capacitors can't filter the voltage properly anymore).
