These work great with MSI AM4 mobo's. I bought these for my wifes build. They look figgen awesome! Once you get the app to work correct. Which when you download it DO NOT unzip the file. First right click and select properties. Then in the general tab go to the bottom and check the unblock. If you don't do this you will get an error from the app for some reason because it can't detect the memory. After I did this I was able to launch the app.

Great RAM, runs at rated speeds, benchmarks well, and is stable. Pretty simple.

Oh BTW THIS IS SO COOL LOOKING IF YOU LIKE RGB!!!!!

For me it is worth every single extra dollar.

Honestly memory now is pretty boring - it either works or it doesn't. And through numerous tests it has been shown that above 16gbs there is no performance increase in gaming and most computer activities with either capacity OR speed increase of the RAM (over 2133Mhz I think).

In other words save your cash and I did that and bought lower speed RAM to get awesome lighting effects.

I have it paired with Corsair HD case fans and 115i cooler with an Asus motherboard that supports Asus Aura.

The Aura software controls the mem chips as well as the mobo and I prefer the rainbow pattern the most.

Did I mention I REALLY REALLY LIKE THIS MEMORY AND THE RGB!

Great glow. I wish my motherboard would remember the last setting. Not sure if this is the fault of the RAM or mobo. I dual boot and have to boot into Windows to set my prefs. Also, I wish the white only light was a little less dingy. Otherwise these are awesome.

Despite all of the issues going on with the corruption of the spd and conflicting with other rgb software, I'm able to use mystic light, cam, and Trident z rgb all at the same time, no conflicts. The ram works great, although the fastest it'll run on my Ryzen build is 2933

This is definitely a recommended buy for anyone building a gaming rig. Look beautiful in the pc and most important part it runs perfect.
