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

After a second or third boot, the BIOS also reverted back to JEDEC speeds (2133Mhz) even though the option XMP was still enabled in BIOS. Naturally the first thing I tried here was to enable the XMP profile for the memory dialing back to 3200MHz. I bought the second "CMW32GX4M2C3200C16", unfortunately it didn't want to work on 3200Mhz, or even lower ~2600Mhz. Manual overclocking of the CPU was quitre a bit more stable, but never got it fully stable on neither 4200, 4150, 4100MHz when I set them as fixed frequency on all cores.

I suspect Ryzenmaster is correct since it was made by AMD and it is right on the other numbers it sees. 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.Import the file in DRAM calculator and then, when you copy the values in the BIOS, choose the alternative values for tRFC (432) and tWRRD (3). When using DRAM Calculator for Ryzen I also discovered their timings more closely matched the "Samsung OEM" profile so that may be the info that might really help you out the most if you use that utility. Generally it is not recommended to mix two different ram kits since you may have compatibility issues. Then I tested the memory with Memtest86 for only one cycle as I knew that if the RAM overclock was going to fail again I just needed to start a game for 10-15 min and see if it will crash.

VENGEANCE LPX is available in several colors to match your motherboard, your other components, your case -- or just your favorite color. I know this is a slightly old post now but I came across it on google trying to find the same information. 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. VENGEANCE LPX DDR4 modules are compatibility-tested across DDR4 systems for reliably fast performance. The DDR4 form factor is optimized for the latest DDR4 systems and offers higher frequencies, greater bandwidth, and lower power consumption than DDR3 modules.

As I said, just use the export option in Thaiphoon and make a html page of the full results of the read. Generally I don't starting trimming timings until after I have stabilized the target frequency I'm reaching for because a really bad or problematic timing might prevent POST.

Now I am testing the manual setting of XMP 16 18 18 36 and 56 - we will see how it will be with stability.So after I managed to get the memory stable thanks to this forum and Jackzz I was excited to see if I will be able to get the CPU stable somehow.
