Corsair 178300 Vengeance LPX 16 GB (2 x 8 GB) DDR4 3200 MHz C16 XMP 2.0 High Performance Desktop Memory Kit for AMD Ryzen, Black

Product Information

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. 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 may consider moving over to the Z version if that's a better option. I know people have really good results getting higher speeds and tighter timings with the Samsung B-die Z version so I'm not sure why the B version I have has different specs if it's the same memory module on there. 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. Part of our exhaustive testing process includes performance and compatibility testing on nearly every motherboard on the market – and a few that aren’t.

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. It's a theory that may seems reasonable but I cannot confirm for sure in any way and would be interesting to understand the difference.

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. In fact... Now on my same board with Ryzen 5 2600X I get 3200 14 14 14 34 timings stable. On MSI boards in the BIOS, they have a list of frequency and timings you can TRY and that one also works. So I can run that or 16 18 18 36 no problem. CAS 14 settings is faster a bit but so far only in RAM benchmarks. Not in anything else. 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 can't find anything recent although the motherboards seemed to be either MSI or Gigabyte boards (but, people were only reporting around 2933 mhz).

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. So which is technically the better memory? I know the Z is supposed to be for AMD and people have good results with it. I've been OK with the B though I do get some strange stuttering sometimes but I'm not sure if that's due to the ram or not. 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. The small form factor makes it ideal for smaller cases or any system where internal space is at a premium. So, I installed the latest BIOS (dont know if that mattered, but at least the beta BIOS is not broken).

For RAM constrained applications, look into more scientific applications. Also worthwhile would be X99 in dual channel vs X99 in quad channel. The CMK16GX4M2B3200C16 seems to be optimized for Intel boards. It runs at a slightly higher voltage than the CMK16GX4M2Z3200C16 and supports XMP 2.0. The CMK16GX4M2Z3200C16 appears to be optimized for Ryzen.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. 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. Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. I don't know if it matters about BIOS version or motherboard manufacturer but I was planning on considering a Ryzen build. 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.

I'm sorry to revive an old thread but i'm investigating the issue and I have a theory that i could not confirm or discard as invalid. said:What was the system build used for the testing? Is it me or it's missing from the article?it seems that part of the article got "cleaned" :) 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).

Apple cancelled this, now what?

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. 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. It may be that the CMK16GX4M2B3200C16 (Optimized for Intel) is using the less expensive and worse hynix chips (they have problems with AM4 but works good with Intel) while The DDR4 form factor is optimized for the latest AMD and Intel DDR4 motherboards and offers higher frequencies, greater bandwidth, and lower power consumption than DDR3 modules. Vengeance LPX DDR4 modules are compatibility-tested across AMD and Intel DDR4 motherboards for reliably fast performance.
