Impact of Hyperthreading?
Disabling hyper-threading reduces CPU performance but saves power and heat. On a 3930k, you disable it via BIOS settings or chipset options to lower power consumption.
It will appear in the BIOS at a specific location determined by the motherboard. Regarding performance, it should be roughly 60-70% of its previous multi-threaded speed, while single-threaded performance shouldn't be impacted unless you compensate with higher clock speeds.
