Corsair VENGEANCE RGB PRO DDR4 RAM 16GB (2x8GB) 3200MHz CL16 Intel XMP 2.0 iCUE Compatible Computer Memory - Black (CMW16GX4M2C3200C16)

Product Information

I also tried changing timings with Ryzen DRAM calculator on the samsung b-die and samsung OEM profiles, but also got BSOD

I did try to set the mem speed to 2666Mhz since that is the official limit for Coffee Lake CPU's but it crashed there as well.Tried entering the memory timings by using the Ryzen DRAM calculator (every which way that I found on the www) VCORE SOC Voltage set to v1.028 - Could not set to v1.025 as suggested as it seems my BIOS only has .022 and .028 options :( Any recommendations on how to better test the RAM? As errors never show up on Membench, but manifest in random occasional BSOD's.

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.Ryzen 7 3700X Gigabyte X570 UD (bios F20b now) 2x8gb ddr4 Patriot Viper [xmp 2.0] (2133/3200) 16 18 18 36 and 64 < for XMP 3200Mhz. I suspected this was to do with overvolting of RAM or SOC initially when I faced many BSOD's (more than 2 per day), as I realised my BIOS VDDG and VDDP was higher than normal (1100 and 1000) when comparing to the Ryzen DRAM calculator 'Safe' values which were recommended at 900. As per another thread, I used Thaiphoon software to read the XMP directly from the kit before importing it and using 'Calculate Safe' option on 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.

Our servers are getting hit pretty hard right now. To continue shopping, enter the characters as they are shown 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€+).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.
