Question B450 pro m2 v2 cpu support

[Blackhawk140]

I have a msi b450 pro m2 v2 mother bord and i just bought a ryzen 7 5700x.. is it compatible with the card after bios update ??

This is when you consult the manufacturer.

B450M PRO-M2 V2

AMD AM4 Micro-ATX professional motherboard, M.2, MSI PRO

www.msi.com

Doesn't appear to be compatible.

Astounding....this seems to be one of the very few B450 boards out there without compatibility with Vermeer processors (Ryzen 5000 series CPU's).

Except the latest BIOS (7B84v4F1) includes AGESA ComboAm4v2PI 1.2.0.A, which does provide compatibility with Vermeer including 5700X processors. It also has a Vermeer SMU (v56.76.0) included in the BIOS. This indicates it should work with a 5700X. It is indeed, however, a bit of a chance if MSI decided to lock it out in the BIOS for some reason. But why include the SMU??? What is probably more likely is they're just not interested in updating the online compatibility lists for an old and long obsoleted board even though they post the updated BIOS.

Since you already bought it update BIOS with your current CPU to the one above and try it out. Be sure to reset CMOS after updating and putting in the new CPU.

I tried that and after the update i got bleuscreen after restarting so i roll back to the previous one.. any solution ?

Being able to revert to the original BIOS suggests it ran in the BIOS screens well enough, which is undemanding of memory. Blue screens while starting up suggests a problem with Windows which is common when memory isn't being properly initialized since it's very demanding on memory.

Did you reset CMOS after the initial BIOS update? Also reset CMOS any time you change processors. I suggest doing it by removing the battery for a couple minutes while also shorting the pins.

What processor were you running at the time it blue screened on the updated BIOS?

I was running 2700x ryzen after bios update and i didnt reset cmos

Resetting CMOS could be the trick to making the updated BIOS work for you. It's certainly worth the try even for the 2700X but also swap in the 5700X if you still have it. But be sure to reset CMOS again after putting in the 5700X: it must be reset any time you change out processor for best success initializing memory.

Something to keep in mind is that motherboard has pretty weak VRM section with only 4 simple phases and none of the FET's under a heatsink. But then it seems to have run OK for you with the 8 core 2700X which isn't as efficient as the 5700X. Once you have it running with the 5700X (think positive!) don't attempt any sort of all-core, fixed overclocking. Instead look into PBO with curve optimizer which undervolts in a way that works well with the processor's boost algorithm which and actually improves on the processor's efficiency. The result is improved performance even though it may run a bit cooler and put less load on the VRM.

What if i change to a520m ?? Is it better vrm than mine (b450m pro m2v2)?

Which board precisely? But probably not since a520's are not capable of overclocking at all. It may not even be possible to enable PBO to set up curve optimizer on one.

But as I said, your board seems to have worked well enough for your 2700X which is less efficient and 105W TDP compared to a 5700X which is 65W TDP rating and more efficient. I'd not worry about it too much so long as not attempting a fixed, all-core overclock.

The good thing about MSI boards is they allow temperature monitoring of the VRM FET's. Get HWInfo64 and watch that temp sensor under typical workloads: if staying under 95-100C you're great. FET's are typically capable of temperatures up to 125C, but only for short duration and not continuous use. Even if you should see temp of 105-125C in a stress test - which is NOT a typical workload - it's not really anything to worry about.

Its ok i update the bios to the last version and the 5700x is working good ...thanks a lot for the advise u saved my money...
So i can now keep using the b450m pro m2v2 without worring
