MSI B450 Tomahawk Conclusion
The MSI B450 Tomahawk had a launch pricing of $120 but can be more commonly found for $100 which not only increases the ever important value factor but means the extra money saved can be allocated to other areas of system improvement such as storage. The B450 Tomahawk is an ATX sized entry-level offering, but when compared to other B450 options it's actually more mid-range and offers a host of price conscientious controllers as a result.
Performance on the whole for the B450 Tomahawk is modestly average in most of the areas. Where it shines is in the power consumption, where it is essentially the best AM4 board we've tested. By comparison, the audio performance wasn't so good, with it coming last out of all the ALC892 boards we've tested.
The MSI Arsenal range of motherboard are primarily targeted at budget gamers and the Tomahawk is positioned as the best from MSI of this particular range. While it's been mentioned throughout much of the review that this board is the successor to the B350 Tomahawk, it's important to highlight the improvements MSI has done to keep their product range as progressive as possible for the consumer. The biggest win in this regard is the power delivery, but not just the componentry (which includes the replacement of NIKOS MOSFETs with those from ON Semiconductor), but MSI has implemented a much cleaner and seemingly more effective 4+2 power delivery with two high side and two low side MOSFETs per phase. The power delivery heatsink also gets a noticeable upgrade in terms of surface area on the top due to a newer extended design, as well as making the heatsinks themselves larger in size, heavier in mass and the B450 Tomahawk heatsinks now actually have fins instead of looking like lazy lumps of metal.
Another plus is the inclusion of two USB 3.1 Gen2 ports on the rear panel which MSI did omit from the last AM4 Tomahawk branded board. The superfast 10 Gbps capabilities come through a Type-A and Type-C port while the rear panel also features a further two USB 3.1 Gen1 Type-A ports and two USB 2.0 ports.
With a current retail pricing of $100, it's hard to ignore the B450 Tomahawk and offers users looking to build a good value gaming themed system with a solid foundation to build upon. The gap between the more budget B450 chipset and higher end X470 chipset boards is bridging ever closer, and this board is a good example of that.

buildzoid has said gigabyte went backwards in memory support for their second gen mobos16gb sticks are more demanding, 32gb total is more demanding
you dont 'need' to buy bdie, but you should be aware of various aspects that can hurt stability
XMP doesnt mean much, the secondary timings are not in the profile, the mobo has to make them up, the mobo may not even be sending clean or high enough voltage, the mobo can cause multiple problems already & that's before the cpu's memory controller variance is even looked at

yeah, i got the B450M Mortar on the suggestion of Buildzoid and am loving it! took my VRM temps at 1700X stock speeds from 87C on the AB350M-DS3H with its wickle cooler to 65C on the Mortarkn00tcn - Sunday, December 16, 2018 - link
if you're still around to read this, i have booted a mortar to 3466 on hynix m-die (gskill trident z 2x8gb) with mostly auto settings, but it was unstable of course (not like i expect hynix to run at this speed at c16)how can you refuse to believe something you have no statistics on? what cpu was it? 32gb is more demanding than 16gb, dual rank is more demanding than single rank (rank not channel, 16gb sticks are likely dual rank)
try 2T CR, try geardown & bankgroup enabled, try 1.36 or 1.37v, try 1.1v soc

I'm not sure it is the retailers fault that the board is not working for you now. They did not do a bios flash and render the board dead now did they. When you installed the board yes it had problems seeing both of your memory sticks and that was because of it having a older bios firmware installed.The fault is that of MSI them selves for having a newer bios that does not seem to be working properly on this model of board. With all of that said the most the retailer can do is offer to take the board in and try to get it working for you and if they are nice won't charge you anything or if they do want to charge maybe a really small fee (since it was them that flashed the board making it useless now.)
As a retailer myself I would offer to take the board in and get it working for free. My own thoughts are because of the board first having issues with your memory sticks on the older bios that is where the problem is. If they took the board in and tried to fix it any good tech with that information in hand would very quickly pull your memory out and use actual memory that is known to work with these boards without problems and then do the flashback again. Chances are that is when the problem will be corrected and you would have a fully functioning board again.
I do think it is good of you not to mention names at this point. I do think that if they have a decent tech on staff this should be a easy fix for them and get you running again. Now if you just want to return the board for the sake of returning it then that is up to them if they want to do that or not. The board is either going to end up fixed or sent back to MSI for replacement. Now if it does end up going back to MSI who pays for the shipping MSI,the retailer or you that is the question.

Can you overclock using p-states with this board?I still use all of the various power saving features on all of my systems, my FX, my Core i5, i7 and Xeon and all but the laptops are overclocked.
I guess I got spoiled with my FX, I could alter base, turbo 1 and turbo 2 settings individually and keep Cool-n-quiet enabled. I'm looking for that capability on my eventual Ryzen build as well.

should be some sort of PBO settingsCellar Door - Tuesday, December 11, 2018 - link
The audio on this board is absolute trash. Not even bad, terrible. It is muddy and with such poor amplification that if you have even an entry pair of headphones such as Audio Technica ATH-M50, you will be barely able hear stuff, and outright forget any soundstage or bass definition.I had no choice but to exchange it for a Asus B450-F - well worth the extra $25. In my 20 years in IT - I've seen better audio on 10 year old prebuilt Dell and no name PCs. MSI should be ashamed they are putting a 'gaming' sticker on this.

I had no issues with my Beyerdynamic DT770's 80ohm pair of cans.Cellar Door - Wednesday, December 12, 2018 - link
From this review - "our testing shows that the B450 Tomahawk performs the worst out of all the Realtek ALC892 equipped boards thus far."83.5db in the dynamic range - no offense but either those DT770 are being wasted on you or you never actually hear what they are capable of when properly amplified.
