Delgado Posted December 21, 2019 Share Posted December 21, 2019 Hello everybody, I have a Corsair DIMM 32GB DDR4-3200 Kit, (CMK32GX4M2B3200C16 v4.32, Vengeance LPX) 2x16GB. I can't get these RAM modules to work with the XMP profile (3200 MHz, 16-18-18-36). I would like to ask a Corsair employee to tell me exactly which memory chips are installed there. Is it Samsung B-Dies or C-Dies or others. Unfortunately Thaiphoon Burner has a read error here and reads Samsung B-Dies (Boltzmann, 20nm) but with B-dies timings I can't get the RAM modules to 3200 MHz. Maybe a Corsair employee can make a statement about the memory chip configuration (see screenshot)? Here is a list of my hardware in which the kit is used: Gigabyte Aorus Elite with the current Bios F11 AMD Ryzen 9 3900X Corsair Vengeance LPX (2x16GB, CMK32GX4M2B3200C16 ver 4.32). The modules are correctly inserted in slots A2 / B2. Link to comment Share on other sites More sharing options...

The modules are correctly inserted in slots A2 / B2. There were some posts not too long ago regarding ver4.32 kits and people having issues. Basically try increasing tRC value between +2 to +6 and see if that fixes your problem. If your trying to use DRAM Calculator for Ryzen choose the "Samsung OEM" profile and see if those numbers are a better fit. Link to comment Share on other sites More sharing options...

McFlufferson Posted June 25, 2020 Share Posted June 25, 2020 Hi I know this is a slightly old post now but I came across it on google trying to find the same information. I'm using the same processor and same RAM and have since discovered that this specific 32gb set of RAM isn't on my motherboard's (asus TUF x570) QVL for ryzen 3000 compability. Only CMK16GX4M2B3200C16, in 2x8gb configuration. 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. Hopefully this helps anyone else struggling with this RAM. Link to comment Share on other sites More sharing options...
