MSI B350 Tomahawk/Ryzen 5 1600x not posting

I decided to do almost a whole rebuild, got a 1600x, msi tomahawk, and 8gb of ddr4 ram, (2, 4gb sticks). I put it all together the right way, turned it on and the cpu debug led is on. I did the CMOS battery thing like some people said, i played with display ports, nothing. Some people say the BIOS needs updated but I don't know how to do that without being able to use the pc, I have another pc that I could download the new bios on and install it if that would work.

Just checked msi compatibility with ram, says that my RAM is not compatible, could that be the reason it doesn't work?

  3. You shouldn't need a BIOS update. Have you checked for bent CPU pins (there are a bazillion of them)? Also, does anything flash on the screen? Verified memory is fully inserted and locked into place?

    Have you stepped through the aforementioned guide?

  4. I checked the cpu, i checked the ram, checked the gpu, all the plugs. I've been told that some of the msi boards don't come with the bios update for ryzen 5 for whatever reason so I think ill just return the thing.

  6. I recently purchased an MSI B350 Tomahawk and a Ryzen 5 1600x. After alot of reading I decided on Corsiar Vengence LPX 3200 DDR4. When I went to purchase the ram the clerk said he didnt recommend Corsair ram with Ryzen CPU, I asked what he did recommend, he said the store had G.Skill Ripjaw 4 DDR4 3000 on sale for $209, $30 cheaper than the LPX Corsair I was going to buy. The G.Skill wasn't on the QVL for the board but I decided to take a chance.
    On initial boot (before even installing OS), I went into the bios and it was showing 3.600 Ghz @ 2133 ram speed with bios version .150, I changed A-XMP to ram 2933 and rebooted, nothing changed. Rebooted and flashed bios to new version .180, back into bios to confirm new version, now .180. Selected A-XMP2 2933mhz AND 3.9 Ghz on CPU. Rebooted again, bios showed CPU running at 3.9 Ghz and ram 2933Mhz, continued to reinstall Windows 10 on Samsung 850 SSD with USB stick with ZERO issues. Computer has been running for a week now and I have yet to have any problems so I wont push it any further. Bottom line is you should flash to latest bios.
