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

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. 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. Details about the extent of our regulation by the Financial Conduct Authority are available from us on request.

For RAM constrained applications, look into more scientific applications. Also worthwhile would be X99 in dual channel vs X99 in quad channel. 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 have a bit of a memory dilemma. I want top upgrade to 32gb of ram, I currently have CMK16GX4M2B3200C16 on a Ryzen 3600X system. 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? The Z version is supposed to always be Samsung B die and the B version (the one I have) people say is usually Hytnix.

The thing is, I think the B version I have is Samsung though it doesn't specify B die. The Manufacturer says Samsung and it just says 8gb/1 die but I'm assuming that's a Samsung B Die. 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. 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 don't know if it matters about BIOS version or motherboard manufacturer but I was planning on considering a Ryzen build. Like I was trying to say to paridoth I think for ver. 4.32 the memory type correlates to "Samsung OEM" in Dram Calculator.

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. If you want to benchmark RAM, it seems like you understand that you need benchmarks that are RAM constrained and compression is part of it, though that's largely CPU bound not RAM bound. In terms of WinRAR specifically, this benchmark offers nothing because your resolution is so poor you can only separate dual cores from quad cores from hex cores, you can't distinguish hex cores with DDR4-2400 from hex cores with DDR4-3200. On top of that, WinRAR is more dependent on the disk so using an M.2 PCIe 3.0 x4 drive should be distinguishable from a SATA-III SSD, is distinguishable from a HDD. You could make the WinRAR benchmark more meaningful by using a bigger data set -- if 1.3GB takes 30 seconds then 15GB should take about 346 seconds and now you can resolve to within 1/346 = 0.29%. Well below what anyone really cares about. 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.

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. 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. 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 Scroll down in thiaphoon report to screenshot your XMP timings. I think the JEDEC timings are listed first in the report, then XMP after.
