To properly configure your system, install a minimum of four memory modules first. ECC memory detects and corrects memory errors within the server environment. Registered also called buffered memory modules register between DRAM modules and the system's memory controller.
ECC Registered Memory transfers less electrical load to your memory controller which makes it more stable and reliable. What is Unbuffered Memory? What is Load Reduced Memory? It is recommended to use identical memory configuration in all channels.

There are many articles, documents and discussions in Internet and there is no definitive answer about the hyper-threading usage in virtualized environment.
A processor architecture feature that allows a single processor to execute multiple independent threads simultaneously. Also called symmetric multithreading SMT. To me the following HP document gives most complete description and recommendations to help taking the best decision for each particular case. Hyper-threading settings recommended for optimal performance:. Performance testing may indicate a zero performance gain when enabling hyper-threading, and in some cases, even degraded performance.
Whether or not the workload or custom application supports more than 64 processors, it is always good practice to test and benchmark these configurations. It also enables the OS and applications to share work between those 2 virtual processors whenever possible, thereby making use of resources that would otherwise sit idle. Make sure hyper-threading is enabled in the BIOS for processors that support it. For the best performance we recommend that you enable hyper-threading ESXi systems manage processor time intelligently to guarantee that load is spread smoothly across all physical cores in the system.
