Hi All, I'm just in the process of building a new system based on the Ryzen 3950X and Crosshair VIII Hero. It's going to be used for a variety of tasks, including gaming, rendering and virtualisation. I initially ordered the 32GB (4x8GB) 3600Mhz 8Pack Xtreem CL16-16-16-36 kit. This seemed to be the best RAM size and performance compromise that I could find in the UK. There do seem to be faster kits available elsewhere, but none I could find here. However, I've just taken on a new project, which is going to require a minimum of 64GB. I'm now in a bit of a quandry as to which RAM to go for. At the moment, I've ordered the Corsair Vengeance LPX 2x32GB 3600 MHz CL18-22-22-42 kit. I'm wondering if I should perhaps have gone for the Vengeance RBG Pro, which is the same price currently. Does anyone know what ICs are actually used on these two types of DIMM? I've read that some of the lower clock speed kits actually have Samsung modules, but that these higher speed DIMMs might either be Micron or Hynix. I've also read that having 4 x DIMMs from the LPX range can be problematic (which might be a consideration in the future if I need to go beyond 64GB). Would really appreciate people's thoughts, or suggestions of alternatives at a similar price point. Thanks, Andy.
