Corsair 163301 Vengeance LPX 32 GB (2 x 16 GB) DDR4 3200 MHz C16 XMP 2.0 High Performance Desktop Memory Kit, Black

Product Information

I currently have got CMW32GX4M2C3200C16 which I bought in October 2018. It's working fine on my Asus x470 pro with Ryzen 7 2700X. Maybe a Corsair employee can make a statement about the memory chip configuration (see screenshot)?

reboot. memtest86. if all good then boot into windows and get your memory settings from Ryzen Master.

Typically first I use the bootable memtest86 USB and don't event bother booting into windows unless at least one pass is successful. 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.

I've come across a number of people having the same problem on different motherboards so I can only assume it's a compatability problem with Ryzen 3000.

Perfect and I have one other I have no idea what is and that is Write Row-Column Delay. I always seem to find 5 settings over the years and only ever four are shown that I could find. Any idea what that would be for these? 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. Want to start test out dram calculator but if thaiphoon burner is showing the wrong info I don't want to tinker with it yet, want to be sure what it really is. 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. 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.
