Review on Thermaltake TOUGHRAM RGB DDR4 3600MHz 16GB: Syncable 💡 RGB Memory with Alexa and Razer Chroma Support - R009D408GX2-3600C18B by Kevin Parker

As some others in the reviews point out, I had the DOCP profile enabled by default and my system wouldn't boot with the clock speed set to 4400MHz. I checked if my motherboard (Asus Prime x570) is on the supported boards list but it doesn't seem to matter. I ended up booting at 4266MHz but less than a day later I got a blue screen error, memory related in Windows so I dropped to 4000MHz and it was stable for a couple of weeks. Not very impressed with RAM, latency is slow and reference speeds are far from impressive. I contacted Thermaltake support and their response is below. I believe with further tweaking you could get the advertised 4400MHz but I'd rather have a stable system. "It is advertised as 4400 at the OPTIMAL load, your CPU silicon can affect this number. Getting to 4266 is already very good, but if you want to get more you'll need to overclock it slowly or get a better processor/motherboard and get the voltage right. I found some information on the internet about this, but you have to do this at your own risk: set the frequency (for now) to 4100MHz, now you have to set the static VCCIO and the VCCSA voltage to stabilize the memory overclock ( Make sure you have the CPU load calibration set to 5-6.) Set both values to 1.1V to start. Now slowly increase by 100MHz on each start.
