for the class of numbers Super prime SuperPrime is a computer program used for calculating the primality of a large set of positive natural numbers. Because of its multi threaded nature and dynamic load scheduling, it scales excellently when using more than 1 thread execution core . It is commonly used as an overclocking Benchmark computing benchmark to test the speed and stability of a system. Background information In August 1995, the calculation of Pi up to 4,294,960,000 decimal digits was achieved by using a supercomputer at the University of Tokyo. The program used to achieve this was Porting ported to personal computers, for operating systems such as Microsoft Windows Windows NT and Windows 95 and called Super PI . SuperPrime is another take on this procedure, substituting raw floating point calculations for the value of Pi with more complex instructions to calculate the primality of a set of natural numbers.

CPU locking is the process of permanently setting a Central processing unit CPU s clock multiplier . AMD CPUs are unlocked in early editions of a model and locked in later editions, but nearly all Intel CPUs are locked and recent models are very resistant to unlocking to prevent overclocking by users. AMD ships unlocked CPUs with their Opteron, FX and Black Series line up, while Intel uses the moniker of Extreme Edition. Intel usually has one or two Extreme Edition CPUs on the market, leading their range in clock speed and starting at 999 1499 USD. AMD has the majority of their desktop range in a Black Edition, with very little price differences from the standard editions. Users unlock CPUs to allow underclocking , overclocking , and front side bus speed compatibility with certain motherboards, but unlocking invalidates the manufacturer s warranty and mistakes can cripple a CPU. However, locking a chip s clock multiplier does not necessarily prevent users from overclocking, as the speed of the front side bus can still be changed to provide a performance increase. AMD Athlon and Athlon XP CPUs are generally unlocked by connecting bridges jumper computing jumper like points on the top of the CPU with electrical conduction conductive paint or Graphite pencil lead . Other CPU models determinable by serial number require different procedures to be unlocked. One of the easiest ways to unlock an older AMD Athlon XP CPU was the pin mod method, because it was possible to unlock the CPU without a permanent modification of any bridges. Just putting one wire or some more for a new multiplier Vcore into the socket would unlock the CPU.

Differential fault analysis is a type of side channel attack in the field of cryptography , specifically cryptanalysis . The principle is to induce faults unexpected environmental conditions into cryptographic implementations, to reveal their internal states. For example, a smartcard containing an embedded secure cryptoprocessor processor might be subjected to high temperature, unsupported power supply supply voltage or current , excessively high overclocking , strong electric field electric or magnetic field s, or even ionizing radiation to influence the operation of the processor. The processor may begin to output incorrect results due to physical data corruption , which may help a cryptanalyst deduce the instructions that the processor is running, or what its internal data state is. ref Eli Biham, Adi Shamir The next Stage of Differential Fault Analysis How to break completely unknown cryptosystems 1996 ref ref Dan Boneh and Richard A.

DISPLAYTITLE H sub 2 sub Ceramic cooling H sub 2 sub Ceramic cooling also called H sub 2 sub C or Hot to Cold is a computer cooling product offered as an option in Dell s XPS gaming systems, advertised specifically as facilitating Cpu CPU overclocking . H sub 2 sub C is a two stage Liquid TEC hybrid cooling system that combines a liquid to air heat exchanger much like a liquid radiator , a Thermoelectric cooling thermoelectric fluid chiller , and control circuitry to optimize CPU cooling with minimal power. According to Dell, the cooling efficiency of H sub 2 sub C contributes to PC systems that are cooler in over clocked mode and potentially quieter in normal operating mode. By cooling the CPU below what is possible with traditional forced air convection or water cooling systems, but preventing the temperature from falling below ambient room temperature , H sub 2 sub C is advertised as extending CPU life while eliminating the risk of humidity condensation .
