Corsair will be not only on the DDR2 memory market size, but also facilitate entry into the overclocking world, Corsair's new memory technology called EPP, which stands for Enhanced Performance Profiles. The Corsair EPP memory allows even beginners to easily get started with the overclocking and with guaranteed success, enthusiasts is provided a tool to the side, which allows the overclocker to achieve the optimum of the memory easier, a first preview of the EPP technology are the following items.
In a new Corsair EPP DDR2 memory on the JEDEC SPD (Serial Presence Detect) ROM specific EPPs (Enhanced Performance Profiles) programmed, which will in turn provide the best storage performance, only the first 96 bits of 128 bit JEDEC SPD ROM to be used, Bit 97 to bit 127 can be used by the respective manufacturer of proprietary information. In this area, the Corsair Enhanced Performance Profiles is programmed Corsair also had to the integrated memory controller for AMD AM2 processors, which will be presented in a few weeks or days to analyze, and now claims to find optimal blend of maximum stroke, the lowest possible timings and other settings.
If an EPP certified memory detected by the BIOS, is an appropriate option enabled and the memory can be set as desired, it is not yet known which are BIOS versions, motherboards and platforms are supported. AMD AM2 processors are, naturally, are between the affirmed models, whether Intel will give permit to the Enhanced Performance Profiles in its BIOS edition and cpu board, is unclear.
The available 30 bits of the JEDEC SPD ROMs can be used by Corsair in two ways for the Enhanced Performance Profiles, since it is not any substantial information in the available 30 bits can be stored is only room for either two or four complete profile of less extensive profiles, in the less extensive profiles, information about the memory voltage, command rate, cycle time, CAS latency, tRCD, tRP and tRAS saved. An example would be 4-4-4-12-2T at 2.1 volts, the entire store profiles also have the following values: drive strength for address, CS, clock, data, DQS, address Delay, Delay Command, Setup Time, CS delay, setup time, tWR Write Recover and tRC.
By default, the Corsair EPP profiles are disabled, so there is no overclocking the memory and run on the specific tree by the manufacturer default settings in addition, the Auto option now, and several overclocking options to the memory at all overclock, it must of course raised the reference clock. This entails, still, simultaneously that the processor would no longer work with the manufacturer's determined clock rates, the BIOS has the choice, naturally, the multiplier of the CPU to sit down in order again to reach the original clock.
Of course, also play a role in dividing the memory controller, the options described so far proposed, in which way both memory and the processor can be overclocked, the Auto is shown in the BIOS version or paraphrased somewhat misleading. When Auto the BIOS determined by the existing optimal processor clock speed, in later versions to this option in BIOS CPU MAX will be renamed and becomes more understandable.
No matter what setting is selected, or the percentage is overclock the processor, the BIOS does not tamper with the other voltages, only the memory voltage is raised in some cases. Processor voltage and remain more important voltage values untouched, Corsair can only for the operation of its own memory modules garantieren, but not for the operation of the processor if there is the voltage increased.
