I specifically want the samsung b-die version (the Vengeance cost ~170€ while others ram modules like G skill Flare X or other modules with samsung b-die chip usually costs 200€+). So, I installed the latest BIOS (dont know if that mattered, but at least the beta BIOS is not broken). My online research has found till now that everyone with hynix chip (RAM version 5.39) have the Intel optimized(B) module while those who owns the samsung b-die (RAM version 4.31) have the AMD Optimized(Z) module.

reboot. memtest86. if all good then boot into windows and get your memory settings from Ryzen Master. Now, I'm not sure if I should go for the same model I have and risk getting a Hynix version or go for the Z which is always B die.

I have a bit of a memory dilemma. I want top upgrade to 32gb of ram, I currently have CMK16GX4M2B3200C16 on a Ryzen 3600X system. I am waiting to see what happens with the new AMD (Ryzen 2?) hardware to be released - I think it's this month or next month. I used the import feature from Thaiphoon because I noticed that even though I put in the correct specifications in all the main fields like rank, number of modules, frequency etc the timings still changed when I used the imported file in DRAM calculator. I left Samsung b-die instead of Samsung OEM, as you suggested, because that would give me invalid numbers. Then I heard about what you said about tRFC and I set the alternative setting (432) as well as the tWRRD (3).

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. 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.

The clever and stylish, low-profile design of DDR4 LPX memory means it can fit comfortably into much smaller spaces. The LPX series of Vengeance DRAM was prepared for when the first of the Micro ATX and Mini-ITX motherboards for DDR4 memory released. In any system that has minimal internal space the small form factor of the LPX DDR4 RAM from Corsair is ideal. I can't find anything recent although the motherboards seemed to be either MSI or Gigabyte boards (but, people were only reporting around 2933 mhz). Any update or reports of this working at that speed or native 3200 mhz on Ryzen AM4 motherboards? Also, does it matter whether it's a B350 or X370 motherboard? I don't know. I haven't been able to confirm what that version really "is" from anywhere. I suspect it's just lower grade b-die.

The latest that I read was around the end of the year (December '17) and a few buyers of this RAM was saying they could only get up to 2933 mhz so I don't know if that has changed. There were no details, though, so I don't know if it mattered about the motherboard or BIOS. Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. Part of our exhaustive testing process includes performance and compatibility testing on nearly every motherboard on the market – and a few that aren’t. I also have a kit of 4.32 ram (different model, size, and dual rank) and found it didn't like tRC timings (and some lower tRFC) out of the box and were a bit problematic to get working. I needed to reconfigure ProcODT, RTT, and SOC to push over DDR4-3200 successfully.I don't know if it matters about BIOS version or motherboard manufacturer but I was planning on considering a Ryzen build. Hi thanks for the reply, did not get anywhere with dram calc and got so tired to reset cmos every time so funny enough I tried your values and that was the best I could get I think for 3600Mhz on my Tomahawk Max board. Finance is only available to permanent UK residents aged >18, subject to status, terms and conditions apply. 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. As you step up in frequency and you can't seem to get DRAM Calculator values to work you can revert to what did work (from the previous step) starting with ProcODT, RTT, and CAD values.
