What's the point of Ryzen DRAM calculator?

Really I don't get what's the use of this app for a mere mortal?
Apparently it's an essential tool for DRAM OCing on Ryzen. But what does it actually do?
I downloaded it, and all I can see that I'd have to fill in a bunch of information I don't have the slightest idea about.
I thought the app would detect the installed RAM, CPU, and MB combo and suggest me a recommended setting based on a database.

So how is this even useful? How should I know any of the info that needs to be filled in?
Ok, I know my cpu type, but how do I find out the memory type? or DRAM PCB Revision, or memory rank?

I used it to dial in some timings on RAM that wasn't qualified for Ryzen at the time. As for Die types and what-not, you'll need to do some research on the modules that you bought. I don't remember the site off the top of my head, but there is a site that has a database of modules to known die types used.

There's a program called Thaiphoon Burner which can be used to read and save the RAM specs to an HTML file which can then be loaded by Ryzen DRAM Calculator to auto-populate the needed info for your RAM. The free version of Thaiphoon Burner will allow you get the specs you need and export them to the HTML file.

The usefulness of Ryzen DRAM Calculator can be hit and miss. Some people have great success with it while others can't get any use out of it at all. In my case I have a Samsung B-Die kit, a lower binned B-Die, and none of the recommendations will even boot for me. That could be because of the RAM or my motherboard or my CPU. I have never had an issue with the XMP settings, though. As soon as I put the system together I loaded the XMP profile and everything worked and was stable.

I've used it to take some modules pretty high. I've gotten my 32GB kit (4x8GB) DDR4 3866MHz modules to just over 4,000MHz. It's B-Die, so that tracks.

Have you had better success with 4x8GB vs 2x16 GB?
I'm curious as well. When I first started on the Ryzen architecture I bought 2x16GB modules and couldn't get them past 2666MHz, mostly because they were dual ranked modules. Switched to 4x8GB modules and had no problem hitting my 3200GHz. I was able to use the calculator get them to 3466GHz, but they weren't overly stable. Had to back it down again to 3200.

I've got 2x16 2666 dual rank modules, and getting them to 3000Mhz was easy. But I never even tried taking them higher yet. That's why I was looking at this app, maybe it could help reduce the trial and error a bit.
