Multiplier Bug found on MSI x370 Sli plus Bios

[combine1237]

Just found a bug on the latest versions of the bios for my msi x370 sli plus bios. This affects versions 3.2 and up on the bios. The bug involves setting the multiplier in the bios. When a manual multiplier is set it will require the actual frequency and not the multiplier itself. So if you entered 3700 into the multiplier box it would put in a multiplier of 37 or a ~3700mhz clock speed. However, if you input 37 into the box it would display 3700 when you press enter and would show up as having a clock speed of 3700mhz in the os and the bios, but this would be incorrect. I think it would believe you are requesting a clock speed of just 37mhz and set the multiplier as low as the board supports to match your request which on my board is 15.5 or a 1550mhz clock speed even though it is displaying otherwise. This bug will become apparent if you use a monitoring program like cpu-z or ryzen master which will display the correct clock speed and multiplier of the board. This may not be a very bad bug as it can be solved by filling out all 4 multiplier numbers in the box before pressing enter, but can be frustrating nonetheless. Right now I can only confirm that this affects the x370 sli bios, but I have read of other people with b350 motherboards from msi having similar issues. If you have an msi motherboard you should probably check to see if it is effected. I do not know if this is already known and being fixed or not. Please let me know if it is.

Intel have run good job making overclocking super easy. You just put in frequency/multiplier, it increases also memory controller speed and other things.

Weird, I have this same issue, and I have been putting all 4 numbers in the correct slot. 

 

You keeping your chip at stock voltage at 3.7?

Nope, I will am using 1.28vcore and my stock is 1.212vcore at 3.7 ghz with the stock cooler. Try the 3.1 bios if you can't figure it out.

I tried the newest one then reflashed to the second newest and still got a the same issue. 

 

It's really a shame cuz it seems like a quality board and I really like the bios setup.

 

But I'll try it out when I get back home and let you know

A) The multiplier only affects CPU frequency.

B) Exactly how it works on current and last gen AMD platforms as well.

yea same issue with the 3.3 and 3.2, 3.1 multiplier works fine for me. kinda stupid but i still complained to MSI.

 

manually inputting hte numbers or using +/- still causes the same issue. but I'm fine with sticking to 3.1, I'm sure it overclocks just as well lol.

Kind of off-topic, but I'm kinda new to OC'ing, and I was wondering how you're fairing with this mobo?  How much tweeking have you been doing in the BIOs?

Not much tweaking just adjusting vcore and northbridge, turning off turbo, and setting it to 3.7 as I am using the stock cooler.

what/where is northbridge on the bios?

[Weyburn]

did you ever find a fix for this?

Sorry to revive an old thread, but I hit this bug in the latest version of the BIOS on ASUS STRIX X370-F (version 0813).

 

Interesting for sure. I just reverted back to Auto and used Ryzen Master and BOOM it works fine.

MSI mobos are trash, this bug is known on them.
