CORSAIR VENGEANCE LPX 64GB (2 x 32 GB) DDR4 3600 (PC4-28800) C18 1.35V Desktop Memory - Black

Product Information

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. Every few tests I also ran a run of TechArp's x264 HD Benchmark. The avg of 4 runs are also shown at the bottom. It's free, and you could say this is a real-world test. While Membench is more a synthetic test, I guess. I've used this motherboard before with Intel 12th gen and 64GB DDR4-3600 was not an issue then but the same doesn't go for Intel 13th.

Gonna be a tough job. How I miss the days when a new GPU or a CPU could boost your simple Quake experience from unplayable to playable. Remember when more RAM even made a huge difference or even a good soundcard? There's some weirdness with this motherboard such as XMP timings and voltage being applied even though XMP is disabled. Part of our exhaustive testing process includes performance and compatibility testing on nearly every motherboard on the market – and a few that aren’t. There's no way to get gear 1 working. I get the occasional boot with 3600 G2 but it's not stable. Tried auto SA voltage and manual. 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.The small form factor makes it ideal for smaller cases or any system where internal space is at a premium.

Now, what bothers me is that the timings in column BG have the highest score for the x264 test. I did further tweak some other timings, which resulted in a faster Membench run, but lower fps for x264 encoding. That's kinda contradictory... But does that 30% difference really translate to something humanly noticeable? We've all had the "wow a NVMe drive is 7 times faster than a SATA drive!" but then had the crushing disappointment of it feeling in 99% of cases just like the old SATA it replaced. 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. 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?Even this failed OCCT: XMP off - 3200 G2 - 18-22-22 - mem 1.25v (which is basically very close to JEDEC). I can try to reduce CL to 15 or 14. I haven't tried anything lower than 16 so far. Any other timings I could focus on?

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 tried getting tRCDrd under 19, but I can't get the system completely stable, even after cranking up the voltage to 1.4V which the calc suggests as max. For tRFC I got a bit confused with what the calc suggested: 630 and alt 560. When I look in the BIOS (well, I should say UEFI) it's set to 'auto' with an actual value of 312 (and tRFC2 192, tRFC4 132). So, that's good, right? Lower is better for this one?After reading up on RAM OC'ing a bit, I found the DRAM Calculator for Ryzen on TPU. Helpful tool, definitely! To figure out which chips are on the DIMMs, I used Thaiphoon Burned. It tells me it has Micron E dies. I left out some of my early tests, and all the failed tests. I tried tweaking every timing up to row 39 'power down enable', but those last ones I couldn't get to work without spawning errors.

I paired the Ryzen 5 3600 with an Asus Prime X470-Pro, and spent slightly more on the RAM compared to an ordinary 3200MHz CL16 set: I went for a Corsair Vengeance LPX kit at 3600MHz CL18-22-22-42.What's the deal with the tRCDrd? How could I get it from 19 to the suggested 17. A higher voltage? Or do the other mentioned voltages in the calc play a role? We're seeing roughly a 30% difference between our best and worst configurations, and these are just for performance memory kits. Whether that matters depends on what you're doing. The reason those big differences don't show up in a review is because it's "not fair" to compare 16GB of DDR4-2400 to 32GB of DDR4-4400. 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. Blowing a little dust of this topic, cause I think I've reached the end of the line on tinkering with my RAM timings. Most likely, but temperature dependent. I run 1.40v and never break 40-42C, but different case environments can produce vastly different results.
