Overclocking

Just like Phenom II X6 1090T, maximum stable clock for 1055T was around 4.1 GHz which is of course great for new AMD's six core processors. Phenom II X6 1055T had no problems pushing very high HT values on our ASUS Crosshair IV motherboard, and the end result was achieved with combination of 290 MHz HT and maximum multiplier of x14.
This time I gave it some more effort so this result was done on 1.465 V (1.488 V overvolted under load), unlike with 1090T where 1.50 V (1.55 V overvolted under load) was used. The difference in power consumption is show below. Time spent tweaking could be well worth it.
