About this deal

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 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 don't know if it matters about BIOS version or motherboard manufacturer but I was planning on considering a Ryzen build.

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. Glad to report that the system did POST and everything seems to be working smoothly. Did some mem testing for around 10 minutes and it didnt crash, so I guess the pc is usable for now. I will stress test and benchmark tomorrow, too tired now. If you get a good match that may be what you really have if there is any doubt. Keep in mind dram calculator is suggesting what you can use. The situation may very from system to system anyway. Like I was trying to say to paridoth I think for ver. 4.32 the memory type correlates to "Samsung OEM" in Dram Calculator. For RAM constrained applications, look into more scientific applications. Also worthwhile would be X99 in dual channel vs X99 in quad channel.Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. 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. If you're building a Ryzen machine, it might be a better idea to get CMK16GX4M2Z3200C16. I'd recommend just getting a 2x8 kit and running it in Dual Channel mode. What is the difference between these two kits: CMK16GX4M2Z3200C16 vs. CMK16GX4M2B3200C16. I will be using it with the r7 1700 with the C6H. What kit is the best to get the highest speed on? I plan on getting 2 sets of them. Are there any other kits you recommend that can fit while using the NH-D15? 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 Klarna Bank AB (publ) is Authorised by the Swedish Financial Services Authority (Finansinspektionen) and is subject to limited regulation by the Financial Conduct Authority. 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. 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).

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 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. Generally I've had good results when enabling GearDown and disabling PowerDown with both my LPX and RGB kits and Zen+ and Zen2 CPU's. Keeping DRAM voltage near 1.35v seemed to be a sweet spot as using higher voltages didn't seem to have any improving effects for my RGB kit and keeping SOC between 1.0v and 1.1v. Overall memory support on my MSI B350M Mortar Arctic has gotten a lot better as well. With B-Dies it can even boot DDR4-3600 into Windows without manual adjustments just on A-XMP. You do still have to make some manual adjustments for full stablity, but that is still a big improvment compared to the early AM4 days. 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.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.
