I would also like to hear from other people who may have had the same issue and for which this solution solved this problem (setting the tRC to 56 instead of 54) I currently have got CMW32GX4M2C3200C16 which I bought in October 2018. It's working fine on my Asus x470 pro with Ryzen 7 2700X.

CORSAIR

Something is clearly not right here. I hope that a future BIOS update will resolve it. But as of now, this kit doesn't work correctly on x570 gigabyte boards. And it is on the QVL, so something is off. 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. Would like to hear if anyone using CMW32GX4M2C3200C16 on an AMD Ryzen build has similar issues and if the above fix solved any potential BSOD issues.

World-famous reliability

After this second RMA, I decided to further try out manual timings for the RAM kit. I had tried this earlier - and followed the ryzen dram calculator settings to the letter - but those also gave me errors. This time, I decided to just set the first five values in BIOS to the exact same as XMP would: 16-18-18-18-36. I noticed that my board would set the sixth value to 75, while XMP sets this to 54. So I tried dialing it down and ended up with 55 and 56 and everything ran fin without errors at 56.

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.Maybe a Corsair employee can make a statement about the memory chip configuration (see screenshot)? 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.

im at 1.4v now at 3600mhz...u think if i rais the voltage i could get tighter timings? ive just been using the memory try it feature on my msi board. In particular this is a good way to get what your motherboard decides to use by default for termination, cad bus, and misc values. This provides a base point where you know what values already work. Latest BIOS Update from GB 10c did not resolve the issue with the XMP profile and BSOD if the timings are not entered manually.Running Memory Stress Test in Intel Extreme Tuning Utility BSOD if I run for more than 30 min even if XMP is disabled in bios. CPU: Ryzen 5 5600x Board: Asus PRIME X570-P Ram: G.Skill Ripjaws V Series 16GB (2x8) DDR4-3000 Case: Fractal Design Define S I know this is rated at 16-18-18-36 but using Ryzen master, or my UEFI, I have no idea what those correlate to so I can switch mine to their proper timings.

Like I was trying to say to paridoth I think for ver. 4.32 the memory type correlates to "Samsung OEM" in Dram Calculator. Edit: for what's it worth: I reproduced this issue with every BIOS version I tried: F10a, F7b, F5g, F5l,and probably more. Edited November 11, 2019 by Djiezes This was me and I wanted to share my experience too, since the problem seems to more widespread than just me. Intel Core™ i7-8700K (Won at LTX, signed by Dennis) | GIGABYTE Z370 AORUS GAMING 5 | 16GB Team Vulcan DDR4-3000 | Intel UrfpsgonHD 630 | Define C TG | Corsair CX450M 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.

Low-profile design

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€+). 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. Running stable on 10c with Win 10 v1909, overnight MemTest86 showed zero errors. Edited November 13, 2019 by RBurgundy Returning the RAM-kit. The shop tested it and it worked fine for them. They claim they tested on a x570 board with a 3600X.
