Level 3 (L3) cache | Cache memory further from the processor core than Level 2 cache, but still in the processor package.Level 3 (L3) cache |
liquid cooling system | A method to cool overclocked processors that uses a small pump inside the computer case and tubes that move water or other liquid around components and then away from them to a place where fans can cool the liquid.liquid cooling system |
memory cache | A small amount of faster RAM that stores recently retrieved data, in anticipation of what the CPU will request next, thus speeding up access.memory cache |
MMX (Multimedia Extensions) | Multimedia instructions built into Intel processors to add functionality such as better processing of multimedia, SIMD support, and increased cache.MMX (Multimedia Extensions) |
multi-core processing | A processor technology whereby the processor housing contains two or more processor cores that operate at the same frequency, but independently of each other.multi-core processing |
multiplier | The factor by which the bus speed or frequency is multiplied to get the CPU clock speed.multiplier |
multiprocessor | A system that contains more than one processor. The motherboard has more than one processor socket and the processors must be rated to work in this multi-processor environment.multiprocessor |
octo | A processor package that contains eight cores and supports 16 instructions at once.octo |
overclocking | Running a processor at a higher frequency than is recommended by the manufacturer, which can result in an unstable system, but is a popular thing to do when a computer is used for gaming.overclocking |
PowerNow! | An AMD technology that increases performance requirement for processors. PowerNow! |
processor frequency | The frequency at which the CPU operates. Usually expressed in GHz.processor frequency |
quad core | A processor package that contains four cores and supports eight instructions at once.quad core |
S1 state | The ACPI power saving mode where the hard drive and monitor are turned off and everything else runs normally. S1 state |
S2 state | The ACPI power saving mode where the hard drive, monitor, and processor are turned off.S2 state |
S3 state | The ACPI power saving mode where everything is shut down except RAM and enough of the system to respond to a wake-up call such as pressing the keyboard. Also called sleep mode or standby mode. S3 state |
static RAM (SRAM) | RAM chips that retain information without the need for refreshing, as long as the computer's power is on. They are more expensive than traditional DRAM. static RAM (SRAM) |
stop errors | An error at the kernel level that is severe enough to cause the operating system to stop all processes.stop errors |
thermal compound | A creamlike substance that is placed between the bottom of the cooler heatsink and the top of the processor to eliminate air pockets and to help to draw heat off the processor.thermal compound |
triple core | A processor package that contains three core processors, thus supporting six instructions at once. triple core |
