Review on Corsair CMK16GX4M4A2400C14B Vengeance LPX 16GB (4X4GB) DDR4 DRAM 2400MHz (PC4-19200) C14 Memory Kit - Blue by Ken Arellano

These memory sticks are both a blessing and a curse because they are the only 16GB sticks that can be used to fully populate the ThreadRipper 128GB motherboard. They do not work reliably at XMP2 speed (DDR4 3200, 1.35V). I have 4 sticks, 64GB, on Gigabyte Designare ThreadRipper 1950x. Unfortunately, I had to replace six memory sticks to get a stable DDR4 3200 system. Some sticks were DoA. Two more ran only with DDR4 2666 (not 3200). Last week a memory stick died after six weeks of operation. Now you need to spend time going through Corsair's RMA process. I wonder if this is an issue with Hynix Vers Samsung B chips. Unless I'm willing to run memory below DDR 3200 and need 128GB of memory, I would avoid that memory at least for x399 ThreadRipper systems. I test the memory with HCI MemTest.
