Only CMK16GX4M2B3200C16, in 2x8gb configuration. Maybe a Corsair employee can make a statement about the memory chip configuration (see screenshot)?

VENGEANCE® LPX 32GB (2 x 16GB) DDR4 DRAM 3200MHz - CORSAIR

With my kit going from DDR4-3200 to DDR4-3400 it wasn't worth it with the looser timings I couldn't seem to trim down, but to my surprise (on the older BIOS) it did allow DDR4-3600 and that fit better with the scaled up timings I had to use anyway. Which one would be smarter to buy, to not cause compatibility issues, but get the best possible performance? I was trying for weeks to get my memory stable at 3600MHz. I tried many different settings offered by the Ryzen DRAM Calculator and non of them worked for me. I was never able to post after applying values provided by the calculator.I was looking at a 2 x 16 GB Corsair Vengeance LPX ram and found out that there were two different models Unfortunately Thaiphoon Burner has a read error here and reads Samsung B-Dies (Boltzmann, 20nm) but with B-dies timings I can't get the RAM modules to 3200 MHz.

If your problem is you can't get your XMP kit to run at XMP frequency then start with JEDEC speeds first (2133 to 2666) with XMP DRAM voltage. Not fully supported it said AND all of the info I am seeing is straight up wrong. When I XMP the values do not match what it says. What my XMP sets is not what Aida64 says the XMP will set (@ 1600 MHz 25-18-18-36 (CL-RCD-RP-RAS) / 54-559-415-255-9-6-36 (RC-RFC1-RFC2-RFC4-RRDL-RRDS-FAW) which is so far off it isn't even funny). In particular this is a good way to get what your motherboard decides to use by default for termination, cad bus, and misc values. This provides a base point where you know what values already work. I am very sorry for my post being so long and please excuse me if my English is not perfect, but it's not my native language.I've come across a number of people having the same problem on different motherboards so I can only assume it's a compatability problem with Ryzen 3000. When using DRAM Calculator for Ryzen I also discovered their timings more closely matched the "Samsung OEM" profile so that may be the info that might really help you out the most if you use that utility. I bought the second "CMW32GX4M2C3200C16", unfortunately it didn't want to work on 3200Mhz, or even lower ~2600Mhz.
