Corsair VENGEANCE LPX DDR4 RAM 16GB (2x8GB) 3600MHz CL18 Intel XMP 2.0 Computer Memory - Black (CMK16GX4M2D3600C18)

Product Information

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. 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? 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. 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?

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? 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? 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. 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.

Overview

The small form factor makes it ideal for smaller cases or any system where internal space is at a premium. First of, next to the Ryzen DRAM Calc I also found some useful info and suggestions here and here. Maybe it can help someone else... 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 Blowing a little dust of this topic, cause I think I've reached the end of the line on tinkering with my RAM timings.

I also ran MemTest86 a few times, and even while bumping up the voltage to 1.45V I can't get it to pass 4 runs successfully. And this I take quite seriously. Stability stays the prime focus.

From the Manufacturer

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. 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. 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...
