Anyways, as long as there is no chipset that supports DDR2-667, these fast DDR2 DIMMs only make sense if users can overclock their systems. What Intel did is implement an overclocking limiter to the MCH chips: If the CPU clock exceeds the threshold (we determined that this is 10% over specification), the required PLL (Phase Lock Loop) will reset and won't refuse to lock that frequency. Basically that is a very simple way of throwing a spanner in the works, as it causes a system crash. Decent motherboards automatically restart and you may try again. The easy way would be to limit all overclocking ambitions to 10% max, but now that Intel added this extra obstacle, I somehow felt compelled to break some barriers. |
