Ryzen Memory QVL: Need some extra help.

[averagejoe426]

I am getting the Gigabyte - B450M DS3H Micro ATX Motherboard and while looking through their memory QVL I notice that RAM kits, for example Corsair Vengeance LPX, have the 64 gb 3200 mhz kit on the QVL but not the 16 gb 3200 mhz. So the main question is, If I get the 16 gb 3200 mhz kit, will I still get the same performance?

It will be close to impossible for motherboard manufactures to test each RAM model and all its configurations.
That is why you might see a configuration listed but not another with the same model.
You could also check the RAM manufacturer, where you will find more RAM models available.

QVL. Qualified Vendor List. Not Qualified Ram List.
There's not that many ram OEMs, but what few there are all sell their ram to different vendors. Hynix for instance sells to Corsair, Adata, Kingston and many others. So you'll see multiple instances where ram is actually identical, with a different brand name, color, heatsink etc. So on the QVL there's actually a lot of ram tested that's exactly the same as a lot more that's not tested.

If you think of it as there's 10 OEMs. There's 100 Vendors. Each Vendor has 1000 different model numbers across the various sizes, speeds, colors, heatsinks, series etc. By the time you get done adding up every different type of ram, on every motherboard (you'd have to test all ram on all mobo's your company makes) you'd end up with a QVL that's 10,000 pages long, covering 10 million different variations and taking 5 years to compile. (made up numbers, but the point is valid, theory sound). Nobody will do that, ever again. So you get companies like Asus who will grab 5 or so different varieties from those 10 OEMs for a total of 50 different configurations, and pick and choose a few different brands to cover the spread.

Will your ram work? Yep, it's already tested more than likely. Somewhere. You just can't tell.
