Hi,

I recently purchased a Ryzen 5 1600 and paired it with a MSI Tomahawk B350 board and 16GB of Corsair CMK16GX4M2A2400C16 RAM. I checked beforehand with MSI support and by consulting the compatibility documentation that the motherboard's stock BIOS (v1.0) was compatible with the R5 1600 and that the memory was also compatible and indeed it was. However, I received all the components and my system wouldn't POST into BIOS. I tried everything to get it to POST including removing all but 1 stick of RAM and unplugging everything except for the CPU, memory and GPU but got the same problem. I even cleared CMOS multiple times using the clear CMOS jumper, and by removing the CMOS battery but to no avail. The EZBug LEDs on the board indicated a CPU detect failure so I presumed the problem was with the CPU so I ordered a replacement. The replacement arrived but yet again I had the same problem.

Now, I am lost for ideas and the only solution I can think of is to update the BIOS using a Ryzen 7 chip but I don't have the money to do this and all of the computer hardware stores I've spoken to say they don't stock high value components and even if they did, they wouldn't break a seal on one just to update someone's BIOS. I'm not even 100% sure this is the problem.

Any help here would be greatly appreciated as I've no idea what to do next. Thank you.

System specs as follows:

CPU: Ryzen 5 1600
Motherboard: MSI TOmahawk B350
RAM: Corsair CMK16GX4M2A2400C16 16GB (2x8GB)
GPU: MSI GTX 970 Gaming 4G

UPDATE: I sent the board back to the retailer who updated the BIOS with a Ryzen 7 chip. It boots fine now.
 


RyZen 5 isnt supported on that board until bios version 1.3, I dont know who told you it was supported on 1.0 (1st release) but they were wrong, R5 wasnt even released then. You will need to borrow a RyZen 7 to flash the bios or send the board back, or send the CPU back and get an R7 instead.

Where in the world are you located ?
 


If you follow the CPU support list link: https://www.msi.com/Motherboard/support/B350-TOMAHAWK.html#support-cpu
it shows that R5 1600 is supported from v1.0 and it was also confirmed but MSI support when I emailed them. v1.3 is just a optimisation update for R5 it seems.

I am based in the UK.
 


I would say that information on the website is wrong, even the board is stating its the cpu.
overclockers.co.uk will flash it for you, or tell you if thats the problem.
 


Okay thanks. I'll send them an email. I presume they would help me even though I didn't buy the board from them?
 


They would give you free advise, they may want a small fee to flash it for you, great company to deal with, very helpful.

 


Okay cheers. I've sent them an email. I'll wait and see if they get back to me.
 


Any luck hearing back from them. Have practically the same setup (different ram but my ripjaws V is also supported according to MSI's site).

Would love to actually get some gaming out of this rig rather than RMA it.
 


Overclockers said they couldn't help me because I didn't purchase the board from them, but the retailer where I got the board from, scan.co.uk, said they would flash the BIOS for me if I sent it back to them. I just have to pay for shipping. It's really frustrating and another cost to add to the already expensive system, but I have no choice :/
 


No, I only bought the board from them :/ I have asked them to test it with an R5 1600 before they send it anyway.
 


Any updates? I have a similar issue.
 


I returned my board but I think this looked promising. You might give it a try

I was helping a guy in inida yesterday with a very similar problem too, he ended up taking his whole kit back to the shop he brought it from, he had an RyZen 5 and Corsair RAM with the Tomahawk board, same problem, couldnt get it to post, when he took it back to the shop, they put Crucial ram in it and it fired up straight away, no issues, anyway, they flashed the bios for him to the latest version and then his Corsair ram worked fine after that.

The MSI link you posted is great, but I think it relies on a bad bios flash or corrupt bios flash before it works, its the same thing as ASUS's crash free bios feature, and although this is kind of a bios problem, its not really, the bios on the board is fine, it see's it as a ram problem.

 


Retailer said they've updated the BIOS and it was successful, but they're taking forever to send it back to me.
 


I just got the board back and it all works fine now.
