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

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 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). I am wondering if anyone has this exact RAM/memory and if they have a Ryzen system, what speed they are able to get? 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.

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. 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. 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.

For RAM constrained applications, look into more scientific applications. Also worthwhile would be X99 in dual channel vs X99 in quad channel. 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. Like I was trying to say to paridoth I think for ver. 4.32 the memory type correlates to "Samsung OEM" in Dram Calculator.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

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). 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. 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. Why do you run WinRAR benchmark that takes about 30 seconds to complete when you have 1 second resolution. You don't actually expect DDR4-3200 compared to DDR4-2400 to give you a 3.3% boost on overall system performance when your previous benchmark showed that the gain in pure memory bandwidth is around 10-15% and the latency boost is around 3%.The Z version is supposed to always be Samsung B die and the B version (the one I have) people say is usually Hytnix. 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.

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 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).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. 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. 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.
