I have two possible DC (double capacity) memory for a z390 Hero XI with 9900k (at 4.8-5.1GHz); with the context of having 128GB in Windows 10 x64.
Timings are a bit different, and price difference is significantly different, even though for an intensive/professional usage, it's not this important but it can be worth a good 2TB NVMe.
I'm a programmer and few of the projects are definitely memory bound (size, latency, and bandwidth of RAM) if not CPU front-end bound or NVMe memory bound (latency and bandwidth).
Is there any specific recommendation regarding timings related to memory operations (which ones ?) and other CPU front-end bound operations/programs ?
